Yarger Engineering, Inc. designs traffic signals. The following are descriptions of their projects.
The City of Plymouth reconstructed Oak Drive north of US 30. Yarger Engineering, Inc. analyzed signal warrants and the design alternatives, prepare the signals timings, and develop the signal plans.
The City of Bloomington redesigned the intersection of Walnut Street and Old SR 37 as part of a trail project. Yarger Engineering, Inc. was hired as a subconsultant to analyze the design alternatives, prepare the signals timings, and develop the signal plans.
The City of Bloomington hired Yarger Engineering, Inc. to develop traffic signal plans for the intersections of College Avenue at Third Street, College Avenue at Fourth Street, and Walnut Street at Fourth Street. The two signals on Fourth Street were submitted for ARRA (Stimulus) funding. The College Avenue at Third Street signal was left out of the ARRA submittal due to funding constraints.
The City of Bloomington is planning to improve Rogers Street from Country Club Road to Rockport Road with curbs and sidewalks. Yarger Engineering, Inc. designed the signal revisions at Rogers Street and Rockport Road.
The City of Bloomington is planning to build an intersection improvement project at Atwater Avenue and Henderson Street. Yarger Engineering, Inc. was prepared a traffic study, developed signal timings and designed the traffic signal.
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, developed and installed signal timings, 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.
The Carey Realty Company development is part of a development pattern along SR 15 north of US 30 in Warsaw, Indiana. Along with Wal-Mart, Lowe's, Lakeside Chevrolet, Petro Planned Unit Development (PUD), and Thompson Thrift Development, the Carey Realty Company development changed 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. They used their own computerized forecasting model and Synchro to forecast and analyze the traffic. Yarger Engineering, Inc. then designed the needed 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 provided the west approach of CR 350 North, which is also known as Sheldon Drive. CR 350 North/Sheldon Drive will provide left and right turn lanes at SR 15. The existing signal was modified for the new lanes.
Per a traffic signal agreement signed by Wal-Mart Stores, Inc. and INDOT when the Wal-Mart shopping center received its driveway permit, Wal-Mart Stores, Inc. contracted with Yarger Engineering, Inc. to design a traffic signal and perform construction engineering. US 6 was under construction of a widening project by INDOT during construction of the signal.
At the request of Brownsburg, Yarger Engineering, Inc. designed a traffic signal for the intersection and performed construction engineering. The project was a design/build contract with James H. Drew Corporation. The traffic signal included coordination with the CSX Railroad for traffic signal preemption and incorporated plans to widen Northfield Drive.
Yarger Engineering, Inc. designed a traffic signal for an existing Wal-Mart store in Paoli, Indiana.
Signal Design, CR England, SR 149 at Tech Drive, Burns Harbor, Porter County, IN
Yarger Engineering, Inc. prepared traffic signal plans, specifications, and bid documents for a new traffic signal on SR 149 at Tech Drive.
Signal Design, SR 3, North Vernon, Jennings County, Indiana
Yarger Engineering, Inc. designed a traffic signal for an existing Wal-Mart store in North Vernon, Indiana.
Yarger Engineering, Inc. designed a traffic signal for an existing Wal-Mart store in Crawfordsville, Indiana. They also redesigned an adjacent driveway to prohibit left turns.
Yarger Engineering, Inc. designed a traffic signal for the intersection of Hart Street at Kimmel Road in Vincennes. They also assisted the City in construction and provided signal timings.
Yarger Engineering, Inc. designed a traffic signal for the intersection of SR 37 at Town and Country Boulevard in Noblesville for a new shopping center. They also assisted the developer with construction inspection.
Fully Actuated Versus Semi-Actuated Signal Systems - A Research Paper
In 1993, Mr. Yarger personally took on a research project into the operation of traffic signal systems using HCS, TRANSYT-7F, and Traf-NETSIM. The purpose was to answer design issues about whether fully actuated signal systems performed better or worse than semi-actuated systems. When confronted with differing opinions as well as his opinion, he did a literature search, but found that there was no factually based information on the topic. His own experience was that fully actuated traffic signal systems were extremely rare in Indiana and that most people believed in order to coordinate fully actuated signals they had to be placed in semi-actuated mode. Having successfully designed, installed, and operated fully actuated systems without going to semi-actuate mode, he knew it was not only possible, but also practical.
For this research, Mr. Yarger selected HCS and TRANSYT-7F for some of the initial optimizations and Traf-NETSIM as the primary analysis tool. The research concentrated on arterial systems, but grew in scope to include pretimed traffic signals and grid patterned street systems. He put in approximately 400 hours of his own time doing the research. In the end, he determined that not only did fully actuated signal systems outperform semi-actuated system, but pretimed systems also out performed semi-actuated systems when not hampered by pedestrians.
Mr. Yarger submitted his paper to ITE as a presentation topic and it was accepted. In September 1993, Mr. Yarger gave the presentation to an international group of traffic engineers at the 1993 ITE Annual Meeting in The Hague, Netherlands. Later that year, he presented it to a national corporate meeting of traffic engineers from HNTB. In 1995, Mr. Yarger also presented the paper at the ITE District III annual meeting.This project demonstrates Mr. Yarger's familiarity with traffic signal systems, which he has acquired through years of study, research, operation, planning, design and maintenance of them. While the research was completely theoretical, his hands-on knowledge was invaluable to the project.
