Yarger Engineering, Inc. prepares traffic impact studies, traffic impact analysis, traffic operational analysis, traffic signal warrant studies, counts, forecasts, parking studies, stop sign warrant studies, speed limit studies, neighborhood calming studies, Safe Routes to School (SRTS) studies and many other miscellaneous traffic studies for developers, governmental agencies, architectural and engineering firms, attorneys and remonstrators.
Traffic operational analyses are a type of INDOT traffic impact study with a reduced scope that typically considers only the existing and proposed site traffic on opening day. Remonstrations are similar in scope to other traffic impact studies, but are performed for those opposed to the particular development or road project.
Yarger Engineering, Inc. also reviews traffic studies prepared by others for governmental agencies, attorneys and remonstrators. For more information, see our traffic study article.
The following are descriptions of Yarger Engineering, Inc.'s projects.
Yarger Engineering prepared a traffic operational analysis that included three intersections for a gas station with a convenience store. They counted traffic at two intersections and forecasted traffic at a third for analysis. They used video to collect the traffic count data.
Yarger Engineering prepared a traffic impact study that included nine intersections with two development options for a large retail store. They used video to count the traffic and collect customer data as they entered and exited the existing store to establish a trip generation rate for the new store. They counted, forecasted and analyzed traffic at nine intersections for three peak periods. They also analyzed crash data for four years on Lewis and Clark Parkway.
Yarger Engineering prepared a traffic operational analysis that included three intersections with two driveway options for an industrial plant expansion. They counted traffic at one intersection and forecasted traffic at the other two for analysis. They used video to convince INDOT that a neighbor’s commercial driveway was inadequate for the semis to allow a connection from it to a new driveway for Dubois Wood Products.
Yarger Engineering prepared a traffic operational analysis for a Ricker’s convenience store that included three intersections. The main highway intersection, SR 38 at SR 47 was a five leg intersection due to a seldom used driveway to the park. It was an all-way stop controlled intersection. Yarger Engineering used micro simulation to address analysis problems created by the skew and the all-way stop.
Traffic Operational Analysis, MVP Parks, SR 135 at 2 Cent Road (CR 250 N), Bargersville, Johnson County, Indiana
Yarger Engineering prepared a traffic operational analysis that included three intersections for a baseball facility with eight diamonds and an 80,000 sft. indoor facility. Video data collection was used for turning movement counts on SAR 135 at 2 Cent Road.
Left turn lanes were recommended for SR 135 at the driveway and at 2 Cent Road, and a southbound right turn lane was recommended for the north driveway on SR 135.
Traffic Impact Study, Huck’s and Horne Properties, US 231 at 44th Street, Jasper, Dubois County, Indiana
Yarger Engineering prepared a traffic impact study that included five intersections for mixed development of retail and residential. There were two horizon years to show phased construction where the Huck's convenience store would be built initially and the rest of the project would be completed 10 years later.
Yarger Engineering prepared a traffic impact study for a large retail and residential development with 18 lots. The study included four intersections with a large off-site industrial development. There were three horizon years. Options were considered that reopened a limited access point to US 50 at CR 200 East that had just been closed in order to allow Gateway Drive to break the limited access control. As a result, INDOT agreed to reopen the CR 200 East limited access point. The site is currently under construction.
Yarger Engineering prepared a traffic impact study for a convenience store that included four intersections with numerous off-site developments. It has three driveways, two new roads and two horizon years.
Yarger Engineering prepared a traffic impact study for remonstration of mixed development of retail and residential that included six intersections. The study used video to document large ongoing problems with traffic flow in the area and micro simulation to demonstrate how much worse it would be with the additional traffic. The video represented recurring congestion in the evening rush hour that backed traffic up 0.7 miles and showed one vehicle that took over five minutes to get through the next signal. The congestion is so bad that the alternate routes using the neighborhood streets are also extremely congested. The study also demonstrated that the proposed traffic signal by the petitioner was unwarranted.
Yarger Engineering prepared a traffic operational analysis that included three intersections for a convenience store and office building. Data collection was delayed on this project due to nearby construction on US 52. Yarger Engineering used video data collection and noticed that during the reply there were no school buses, but there are three schools nearby. It turned out that the initial data collection that was already delayed due to road construction needed to be delayed again due to the schools being on a balanced calendar and the date that the videos were first taken was during the break. Without using video, the school break may not have been detected and corrected. During the data collection Yarger Engineering also found an issue with the traffic signal's detection, signage, and pavement markings, and worked with INDOT to get them corrected.
Yarger Engineering prepared a traffic impact study that included six intersections with two driveway options and two horizon years for a convenience store and small retail center. They then prepared the driveway plans with turn lanes on US 30 and on SR 13 for submittal to INDOT for driveway permits. Yarger Engineering worked with INDOT to move an existing break in the limited access right-of-way to a mutually agreed to better location.
Yarger Engineering prepared a traffic operational analysis for a convenience store. They also provide truck turning path analysis for the site engineer to show that tankers and other semis could maneuver on the site.
Concerned neighbors hired Yarger Engineering, Inc. to prepare a parking study related to a propose brewery with a restaurant and beer garden in order to remonstrate against the project. The proposed brewery was initially to have 350 indoor seats, 150 outdoor seats and standing room for another 100 people. They were also considering having concerts that would have up to 800 people plus staff. Per the City's requirements, they should have 232 parking spaces and only proposed to have 54 spaces on site and borrowing some from an adjacent development. Yarger Engineering also calculated the likely parking demand using information from the Institute of Transportation Engineers as 384 spaces for the 800 patrons plus staff during concerts. This meant that the overflow parking would likely park on the street in the adjacent residential neighborhood. Yarger Engineering then prepared an inventory and usage of the adjacent neighborhood to show that the neighborhood would be significantly overcapacity with the existing residential parking and the concert parking.
Yarger Engineering prepared a traffic operational analysis for a large industrial building that included three intersections with two driveway options. Yarger Engineering spotted a potential hazard where existing traffic were using the flush median as a westbound acceleration lane for northbound left turns. This median would become the new eastbound left turn lane into the site, so Yarger Engineering recommended a center curb to separate eastbound and westbound traffic. They also recommended a larger radius at the existing intersection to accommodate semis that had been jumping the curb and creating ruts in the grass behind the curb.
Yarger Engineering prepared a traffic operational analysis for a convenience store that included three intersections and a new road which changed in the traffic patterns in the area. The existing US 40 driveway to the empty site was reused for the convenience store. They also prepared road design plans to install a median center curb in US 40. A prior development across the street was supposed to put in the median center curb, but didn't believe it would fit in US 40.
Yarger Engineering prepared a traffic impact study for industrial development that included two intersections. In order to get better forecast of traffic from the site, Yarger Engineering studied traffic at Farbest Foods’ poultry plant in Huntingburg, Indiana. They provided a numerous road improvement alternative to address the increase of traffic, and forecasted and analyzed traffic for four scenarios for improvements that would have changed how traffic was distributed in the area. Some of the alternatives included: signalizing one of the two intersections or the other, J-turn intersections, and left turn acceleration lane in the median.
Yarger Engineering prepared a traffic impact study for residential subdivision that included three intersections with numerous off-site developments.
Yarger Engineering prepared a traffic operational analysis for a mill. Because mills are not included in Institute of Transportation Engineers’ Trip Generation Manual, Yarger Engineering studied traffic and truck weigh tickets at an existing JMS Milling site to forecast traffic at the new site.
Yarger Engineering prepared a traffic operational analysis for utility office and maintenance shops that included three intersections. Because utility offices and maintenance shops are not included in Institute of Transportation Engineers' Trip Generation Manual, Yarger Engineering studied traffic at an existing facility to forecast traffic at the new site.
Yarger Engineering prepared a traffic operational analysis that included three intersections for a convenience store.
Yarger Engineering, Inc. provided hose and turning movement counts at various locations.
Yarger Engineering prepared a traffic operational analysis for an expansion of Huck's convenience store that included two intersections. One of the existing driveways was closed and a new driveway was installed allowing better internal circulation with the expansion.
As a result of a proposed shopping center, the median crossover of an intersection leading to Huck’s convenience store was proposed to be closed. Yarger Engineering, Inc. critiqued the developer’s traffic impact study and prepared a remonstrators traffic impact study to allow the intersection to remain fully opened and signalized. As a result of the remonstration, the Kentucky Transportation Cabinet decided to replace a ramp to US 60 that allowed for adequate intersection spacing for the KY 54 (Parrish Avenue) at Byers Avenue/Ragu Drive intersection to remain open.
Yarger Engineering prepared a traffic operational analysis for a church.
Bethany Christian Church moved to a new building on the south side of Washington. The site is much larger than needed by the Church, so they plan to sell off lots for other development, such as restaurants, convenience store, and apartments. They also planned to have soccer fields behind the church. Yarger Engineering, Inc. was hired to prepare a traffic impact study for the phased development of the site and to prepare roadway plans for a new driveway and turn lanes. After several changes to the site plan and eventually selling off the unused land as farm land, the driveway to the church was designed and constructed without turn lanes.
Yarger Engineering, Inc. prepared a traffic impact study for a proposed development including a truck stop, hotel, and restaurants on SR 3 in Spiceland. They also considered two fast-food restaurants that may be developed on the other side of SR 3 by others.
Yarger Engineering, Inc. prepared a traffic signal warrant study for a proposed Culver’s Restaurant in Warsaw, Indiana. The Culver's is located about 300 feet to the southwest of the intersection of Parker Street at Patterson Road. A signal was not found to be warranted.
The City of New Albany is developing an industrial park on the west side of SR 111 (Grant Line Road) in New Albany. Yarger Engineering, Inc. prepared the traffic impact study of 11 intersections including the I-265 at SR 111 interchange. It also contained two horizon years and two improvement alternatives options.
Pittsboro Elementary School constructed a new building that essentially double the size of the school. Schmidt Associates prepared construction plans for the new school building and asked Yarger Engineering, Inc. to prepare a traffic study and help address the current queuing problem with vehicles that drop off and pick up students. Yarger Engineering, Inc. studied the existing traffic, forecasted traffic with the new building, and developed several options to address the existing and future conditions.
Indiana State University relocated the Colleges of Business and Education from their home in the Statesman Towers to the Federal Building and University Hall. The building and site plans were prepared by Schmidt Associates, who asked Yarger Engineering, Inc. to prepare traffic studies for the nearby intersections to the new locations. Yarger Engineering, Inc. forecasted traffic including large volumes of pedestrians, developed and analyzed alternative intersection improvements, and prepared reports for the new locations of the College of Business and the College of Education.
The City of Plymouth hired Cripe Architects + Engineers to design a reconstruction project for Oak Drive. Yarger Engineering, Inc. was hired as a subconsultant to analyze signal warrants and the design alternatives, prepare the signals timings, and develop the signal plans.
Laxen Estates is a plan development inside of Forrest Commons in Avon. Concerned neighbors worry that the existing local streets are already over burdened due to the lack of a second entrance into the neighborhood and long cul-de-sac lengths. They remonstrated against the development and asked Yarger Engineering, Inc. to provide traffic information to support their position.
The City of Bloomington built an intersection improvement project at Atwater Avenue and Henderson Street. Yarger Engineering, Inc. prepared a traffic study, developed signal timings and designed the traffic signal.
A group of concerned neighbors remonstrated a proposed residential development on Thixton Lane in Louisville, KY. They asked Yarger Engineering, Inc. to provide traffic information to help justify their position, including a travel time study and a survey of the roadway widths on Thixton Lane and other roads.
A group of concerned neighbors remonstrated a proposed residential development in the southeast corner of Five Points Road and Hanna Avenue in Indianapolis. They asked Yarger Engineering, Inc. to provide traffic information to help justify their position.
Intrametco plans to reopen a gravel pit on CR 600 North. The County asked for a traffic impact study for the driveway reconfiguration and to access the impacts on the nearby intersection of SR 9 and CR 600 North. Yarger Engineering, Inc. prepared the traffic study.
The City of Hurstbourne is concerned about a very large development called Oxmoor Farm just to the west of the City. The development is a mixed use with retail, office and residential uses. It occupies 386 acres and is estimated to generate 55,000 vehicle trips per day. The development plans call for connecting to stub streets in Hurstbourne’s residential area. The City already experiences a great deal of cut-through traffic due to high levels of congestion on Hurstbourne Parkway and Shelbyville Road. In addition, the University of Louisville’s Shelbyville campus is directly across Shelbyville Road from the City of Hurstbourne and is planning to expand. The City asked Yarger Engineering, Inc. to review the existing traffic studies and help address concerns about the cut-through traffic anticipated by the City.
The Kentucky Transportation Cabinet planned to shut down one of the two US 41 bridges over the Ohio River and detour traffic to the other bridge. Ellis Park Race Track is located at the northern end of the bridges and was concerned about the congestion that reducing the bridges from four lanes to two lanes would create and how it would impact access to their track. Ellis Park hired Yarger Engineering, Inc. to assist with convincing the Kentucky Transportation Cabinet to change their plans and allow four lanes of traffic across the Ohio River. The Cabinet agreed and put three lanes on one bridge and one lane on the other while they painted the bridges. The traffic control plans for the bridge painting closed the crossover to the main driveway, so Yarger Engineering, Inc. also prepared traffic control plans for Ellis Park's internal traffic.
Duke Realty developed Walnut Creek Market Place on US 421. As part of a driveway permit, INDOT required a center curb be installed in US 421 by the developer. This center curb cut off access to and from properties on the west side of US 421. Yarger Engineering, Inc. was hired by the businesses on the west side to help mitigate the impacts of the center curb.
Pilot Travel Centers, LLC developed a truck stop with a McDonald's restaurant in the southeast corner of CR 400 North and CR 200 West, just off of I-74 in Shelbyville. Yarger Engineering, Inc. prepared a traffic impact study, designed a traffic signal, and provided construction engineering for the signal. The traffic impact study included several future offsite developments, four driveways to the truck stop and one public intersection.
Community Schools of Frankfort is planning to build a new elementary school on SR 39 at Kelley Road. Yarger Engineering, Inc. prepared a traffic impact study for the school. The scope included data collection, forecasting, capacity and loading analysis, and writing a report. Because of the unusual nature of the school traffic in Frankfort where many parents pick up their children from school, Yarger Engineering, Inc. collected trip generation and loading data at the three schools being merged into the new school. As a result of the loading analysis, the curbside waiting areas were increased about ten fold to deal with waiting parents.
Wal-Mart Stores, Inc. developed a Supercenter in Heartland Crossing on SR 67 in Camby. Yarger Engineering, Inc. prepared a traffic impact study that included ten intersections, numerous on-site and off-site developments, and several roadway options. As a result of the study a median crossover and a new signal were installed and several roads were widened.
The Carey Realty Company development is part of a recent development pattern along SR 15 north of US 30 in Warsaw, Indiana. Along with Wal-Mart, Lowe's, Lakeside Chevrolet, Petro PUD, and Thompson Thrift Development, the Carey Realty Company development is rapidly changing the face of northern Warsaw.
Yarger Engineering, Inc. prepared the traffic impact study and roadway improvement plans for SR 15 and CR 350 North. The study scope included one intersection at SR 15 and CR 350 North. Yarger Engineering, Inc. used its own computerized forecasting model and Synchro to forecast and analyze the traffic. Yarger Engineering, Inc. then designed the need intersection improvements and provided construction engineering and inspection services. As a result of the study, SR 15 is being widened to provide left and right turn lanes to CR 350 North. CR 350 North teed in to SR 15 from the east. This project will provide the west approach of CR 350 North, which is also know as Sheldon Drive. CR 350 North/Sheldon Drive will provide a left and right turn lanes at SR 15. The existing signal was modified for the new lanes.
The Thompson Thrift Development is located in the northwest corner of SR 15 at CR 300 N in Warsaw. Yarger Engineering, Inc. prepared the traffic impact study and roadway plans, and provided construction engineering and inspection for SR 15 and CR 300 North.
The study scope included three intersections on SR 15 and CR 300 North. Yarger Engineering, Inc. used its own computerized forecasting model and Synchro to forecast and analyze the traffic. Yarger Engineering, Inc. then designed the roadway improvements and provided construction engineering and inspection services. As a result of the study, SR 15 was widened to provide left and right turn lanes to CR 300 North. CR 300 North was widened to provide a left turn lane at SR 15. The southeast corner was improved to facilitate semis turning into Da-Lite Screens.
Yarger Engineering to prepare the traffic impact study for submittal to INDOT, Michigan City, and La Porte County. Yarger Engineering counted traffic at five existing intersections and analyzed traffic flow at three existing intersections and three proposed driveways with and without the new development. The extra locations were counted to address traffic volume differences between the existing intersections that were analyzed.
Local homeowners were concerned about a proposed open pit mining operation in their neighborhood. The proposed use would have generated significant dump truck traffic on Hazel Dell Parkway and 106th Street.
Yarger Engineering researched the petitioner's file in the Carmel Department of Community Services and visited the site. They conducted an informal floating car technique speed study and estimated the sight distance at Hazel Del Parkway and 106th Street. Dump trucks require additional intersection sight distance over passenger cars. They also commented on several other traffic related issues.
Local homeowners were concerned about a proposed strip mining operation in their neighborhood. The only driveway to the site was located on SR 37 across from Perry Road in Morgan County. The proposed use would have generated significant dump truck traffic, which requires additional sight distance over passenger cars. Yarger Engineering measured the sight distance at the intersection and took a speed study to show that three fourths of the traffic exceed the speed limit. The speeds were critical because of the limited sight distance at the intersection was barely adequate for the posted speed, but inadequate for the majority of traffic. Yarger Engineering presented its findings in the remonstration portion of the zoning hearing.
A new heart hospital was proposed for New Albany on Payne Kohler Road. Payne Kohler Road is a two lane county road that tees into Blackiston Boulevard. Blackiston Boulevard then tees into Charlestown Road and Blackiston Mill Road. The intersections are stop sign controlled. Charlestown Road is a five lane roadway. Blackiston Mill Road is a two lane roadway that widens to provide left and right turn lanes at Charlestown Road. The intersection of Charlestown Road and Blackiston Mill Road is signalized.
Southern Indiana Rehabilitation Hospital is located adjacent to the south of the site. They have experienced congestion problems with several intersections in the area and were concerned about the additional traffic and congestion that would be created by Kentuckiana Heart Hospital. Yarger Engineering provided an independent traffic impact study for the proposed hospital. The study included ten intersections. The primary intersections of concern were Blackiston Boulevard at Charlestown Road and Blackiston Boulevard at Blackiston Mill Road. Both are two way stop sign controlled. In the remonstration portion of the zoning hearing, Yarger Engineering presented their findings and the problems with the petitioner's traffic study.
Eagle Creek Homeowners' Association was concerned about a soccer complex that Indy Parks proposed on the east side of Reed Road and south of 56th Street. They believed that the entrance would not be across from their entrance, but were later told by the Park's Department that the entrance was relocated from Burkwood Way to Shadow Wood Drive for traffic safety reasons. The association doubted the validity of the statement and wanted an independent traffic study to confirm or deny the claim.
Yarger Engineering surveyed the roadway and compared the sight distance at the two intersections. Yarger Engineering also provided additional traffic information and study criteria for the association to use in its remonstration.
Kohl's Department stores hire Malcolm and Associates to locate a site for a new store in Warsaw and do a feasibility study. Malcolm and Associates hired Yarger Engineering to prepare a traffic impact study for the single use site. INDOT and the City of Warsaw required extensive roadway improvements to approve permits. The project was turned over to Thompson Thrift Development, Inc. so they could spread the costs of the required improvements over more tenants.
The City of Indianapolis contracted with Engineering Design and Inspection Services to design sixteen traffic signal modernizations. As part of the project, a CMAQ funding study was required. EDIS subcontracted Yarger Engineering, Inc. to forecast traffic, conduct speed studies, and estimate the speed improvements from implementing the signal modernizations in the current and design year.
Ameriplex is a 1,300 acre commercial development on the south side I-70 between the Hendricks County Line and I-465 with industrial park and retail uses. Part of the industrial park development has already been developed. A new interchange is proposed for I-70 and Six Points Road. Six Point Road will then become Ameriplex Parkway as it crosses through the middle of the Ameriplex development. Holladay Properties hired Yarger Engineering, Inc. to forecasts traffic for the development, review the proposed roadways in the area, and make recommendations.
A new residential development requested a zoning variance in Johnson County. The adjacent neighborhood to the north was concerned about connecting the two neighborhoods because of potential cut through traffic, speeding, and a sight distance problem that would be created by connecting the two neighborhoods. On behalf existing property owners, Yarger Engineering, Inc. reviewed the existing and proposed roadway plans and documented the sight distance problem. Yarger Engineering developed alternatives to eliminate or at least reduce the cut through traffic and speeds. By reducing the speeds, the sight distance problem would be lessened.
Yarger Engineering, Inc. reviewed the traffic study and roadway plans for a proposed safety improvement project by Ball State University for the City of Muncie. The project involved reconstruction of McKinley Avenue and various side streets to provide a pedestrian refuge in a new median. It also involved modernizing the traffic control devices. At issue with the project was determining if the capacity of the proposed facility would be sufficient for the next 20 years. The traffic study prepared by BSU's traffic engineering consultant only forecasted to 2010.
The two signalized intersections have some unique features due to the extremely large number of pedestrians. The most prominent feature is the use of pedestrian scramble phasing. This is a very time- consuming way to move pedestrians and wastes intersection capacity. Traffic currently queues up for two to three blocks during peak times.
Traffic forecasting was also an issue with the study. The two primary reasons were the study's horizon year (2010 vs. 2023) and the recent plans to move major parking structures and buildings.
Yarger Engineering, Inc. reviewed the traffic signal operations and developed alternatives to the proposed plans to account for 2023 traffic levels. Alternatives included different lane geometry, longer turn lanes, different signal and pedestrian phasing, optimized signal timings, and progression alternatives.
Hamilton County Highway Department planned to widen Fall Creek Road and 96th Street at County Line Road. Local property owners hired Yarger Engineering, Inc. to review the need to widen the roads. After reviewing the plans, Yarger Engineering, Inc. was able to convince the Hamilton County Commissioners that the proposed four and five lane sections were too wide for the forecasted traffic east of the intersection. The review is still under way for the intersection and to the west; however, the Commissioners are very doubtful if Fall Creek Road west of the intersection will ever be widened.
The current intersection is a conglomeration of minor widening projects and split phasing for 106th Street. The intersection design proposed by the Hamilton County Highway Department included several new turn and through lanes, plus a standard eight phase traffic signal. At the request of the Clay Township Trustee's Office, Yarger Engineering, Inc. reviewed the traffic study and plans. Several deficiencies and over designed items were discovered. The most crucial issues discovered in the review were that the through and turn lanes were not long enough to work as initially thought. In a detailed operational review, queues were found to stretch of over half a mile with a design that a less detailed analysis using HCS found to work fine. The assumptions of the HCS were violated, but not discovered until Yarger Engineering, Inc. reviewed the plans. Yarger Engineering, Inc. then presented alternatives to provide a design that would truly function in the desired manner.
Yarger Engineering, Inc. performed a traffic impact study for a new elementary school on Grassy Branch Road in Westfield, Indiana for the Westfield - Washington School System. The school site plan proposed a single driveway to the site. Most of the surrounding land was vacant for many miles to the north and east. Yarger Engineering, Inc. determined the likely growth of the community to north and east of the school, forecasted the traffic in front of the school, and determined lane geometry and traffic control needed on Grassy Branch Road and within the site. Yarger Engineering, Inc. also commented on a nearby intersection that would need major improvements with or without the school.
A developer submitted plans to insert a new housing subdivision that the adjoining neighborhood associations felt would lower their property values. The main issues were double frontage lots and vehicular speeds. By building a street in the new area, there would only be enough land for one row of houses and thereby create double frontage lots out of the existing lots. This street would also be long enough to encourage through traffic to reach high speeds. Yarger Engineering, Inc. was asked to review the plans and Carmel Subdivision Ordinances, and then comment on the concerns. Working with an attorney and the Carmel Planning Commission, the group was able to reach a compromise that did not include the offending street, but still allowed the development.
The Petro Planned Unit Development (PUD) is located on the west of SR 15 between CR 250 N and CR 300 N. Yarger Engineering, Inc. prepared the traffic impact study and roadway improvement plans for SR 15.
The study scope included six intersections on SR 15 including two interchange ramps. Yarger Engineering, Inc. incorporated data from previous studies for the other developments and INDOT counts. Yarger Engineering, Inc. used its spreadsheet based forecasting tools and internally developed version of the highway capacity manual for the project. The company also used Synchro and SimTraffic to analyze the existing and future traffic conditions.
As a result of the study, Yarger Engineering, Inc. designed SR 15 to be widened from two to four lanes plus left and right turn lanes to the driveways for Petro PUD and Lakeside Chevrolet.
Lakeside Chevrolet wanted to move from SR 15 south of US 30 to a new location just north of US 30 in order to expand. In order to get a driveway permit, INDOT required a traffic impact study that included six intersections on SR 15 including two interchange ramps. Yarger Engineering, Inc. used its spreadsheet based forecasting tools and internally developed version of the highway capacity manual for the project. They also used Synchro and SimTraffic to analyze the existing and future traffic conditions.
In 1998, Duke Corporation sought zoning changes to the northwest, southwest, and southeast quadrants of I-465 and US 31 in Hamilton County, Indiana. Neighborhood groups in the area and private individuals banded together to form the Heartland Coalition to remonstrate the zoning changes, and more importantly, the deterioration of their quality of life due to increased traffic congestion that would result from the more than a million square feet of new office and retail development.
Yarger Engineering, Inc. provided traffic engineering assistance to Heartland Coalition in the form of reviewing the developer-prepared study and by preparing an independent traffic impact study that identified deficiencies in the proposed roadway improvements by the developer to mitigate the increased traffic. The study consisted of the I-465 ramps, US 31, 96th Street, 103rd Street, Spring Mill Road, College Avenue, and various driveways. Yarger Engineering, Inc. demonstrated that the development was too large for the surrounding roadway network to handle even with proposed modifications. The scope of the development was dramatically reduced and the traffic was reanalyzed. Yarger Engineering used Synchro and SimTraffic as well as internally developed versions of the highway capacity manual to analyze the traffic. The Synchro and SimTraffic were selected for their ability to show graphically the congestion problems to the Carmel Planning Commission in Carmel City Council.
In a related project, the College Hills neighborhood was redeveloped as an office complex. This project is immediately east of Parkwood Crossing. Yarger Engineering again used Synchro and SimTraffic to demonstrate the resulting congestion. (Aerial photography provided by Above All Photography, Ltd.)
INDOT has developed roadway plans to widen SR 66 in Evansville. On behalf of KDDK, a law firm representing some property owners along SR 66, Yarger Engineering, Inc. worked with INDOT to minimize impacts from the right-of-way takings and assisted the property owners with internal circulation plans for the resulting roadway geometrics. Yarger Engineering, Inc. looked for ways that both INDOT and the property owners would benefit from their proposed changes to the roadway plans. One example is the closing of one driveway nearest an interchange and the relocation of another that resulted in about a 90% reduction in the number of parking spaces removed from an auto dealership. The new driveway location also resulted in better internal circulation.
The existing intersection had single lane approaches to a four-way stop. The intersection design proposed by the Hamilton County Highway Department included several new turn and through lanes. At the request of the property owners in the area, Yarger Engineering, Inc. reviewed the traffic study and plans. Several deficiencies and over-designed items were discovered. Yarger Engineering, Inc. then presented alternatives to provide a design that would truly function in the desired manner while saving many acres of private property and lowering the cost of the project. For example, one family saved about 20,000 sft of frontage on Towne Road.
University High School developed a private high school in the southwest corner of 116th Street and Towne Road. Yarger Engineering, Inc. prepared a traffic impact study consisting of seven existing intersections and three new driveways. The company also prepared plans and specifications for a driveway and associated turn lanes on 116th Street in coordination with nearby projects by Carmel and Hamilton County.
INDOT plans to upgrade US 31 to a freeway in Hamilton County. On behalf property owners, Yarger Engineering, Inc. is reviewing the status of the project and commenting on the proposed changes.
In 1997, INDOT contracted with Dames and Moore to provide traffic data collection services. Dames and Moore subcontracted with Yarger Engineering, Inc. to provide technical expertise and local area knowledge. When requested by INDOT, Yarger Engineering, Inc. scoped out the counts and estimated the fees required to collect the data. Dames and Moore personnel then placed the counters and retrieved them a couple of days later. Yarger Engineering, Inc. reduced the raw counter data and reformatted it to be compatible with INDOT's data collection software.& Some of the locations counted included I-80/94 in Lake County and I-465 in Marion County. These involved special counters that did not have compatible file formats to INDOT's data collection software. Yarger Engineering, Inc. developed translation procedures to convert the data into an acceptable file format.
In 1982, Mr. Yarger personally took on an analysis project of US41 in Terre Haute using NETSIM. The purpose was to investigate closing a cross over that was experiencing left turn accidents. Locals complained that INDOT's plans to close the cross over would substantially increase the delay at a nearby signal that was already over capacity. On behalf of the Crawfordsville District Traffic Department, Mr. Yarger analyzed the before and after conditions using NETSIM. Because of the very complex nature of the intersection, the actuated traffic signal, and the unsignalized intersection, NETSIM was selected for the analysis tool. At the time, it was the only tool capable of analyzing all the components at the same time. The analysis showed there would be substantially no difference in the delay at the signalized intersection. Mr. Yarger presented his findings at the Indiana Section - Purdue Student Section Joint ITE Meeting.
