Other traffic engineering services provided by AGA include traffic safety studies, speed surveys, parking studies, street light design, demonstration projects, bicycle studies and facilities design, transit studies, truck studies, pedestrian facilities studies, and expert witness testimony. AGA has developed various custom-designed software packages to assist traffic engineers in analyzing data such as determining traffic flow, accident statistics and signal operating characteristics. The software is also used on an on-going basis by AGA staff to efficiently perform engineering services for clients. One example is HCM (Highway Capacity Manual) software developed by AGA staff to provide an interactive simulation and analysis of traffic signals based on state-of-the-art HCM delay methodology. The program, WEBSTER, is a direct application of the 2000 Highway Capacity Manual. It provides for signal timing development, capacity analysis and Level of Service determination. The signal timing feature, which is not typical of most HCM software, allows for very efficient signal operation, and is critical for determining proper system cycle lengths for coordinated signals. TRAFFIC SIGNAL OPERATION AGA operates traffic signal systems for various governmental agencies and does so remotely from our Fullerton office, which includes a mini TMC (Traffic Management Center). Existing systems include 31 signals on a TRACONET Type 90 system in La Habra, 40 signals on a QuicNet Model 170 system in Montclair and 13 signals in Lorna Linda. We are responsible for signal timing maintenance for 140 signals in the City of Fullerton on an on-call basis. We have also controlled Model 170 systems for the Cities of Santa Clarita and Huntington Beach from our TMC, as well as a coordinated signal system for the County of San Bernardino on Cedar Avenue. Additionally, AGA staff have implemented and fine tuned coordinated timing on several other systems including QuicNet, TR.i\CONET, Multisonics VMS, Econolite ZONE MONITOR, and CSC MICS. Several of these systems are also being periodically monitored remotely from our office. This unique "hands-on" signal experience, combined with our senior staffs previous experience as City Traffic Engineers, allows AGA staff to possess a very realistic understanding of what it takes to adequately serve the public while maintaining political harmony. Our TMC staff also includes a signal system specialist who has previous field maintenance experience with a local Signal Maintenance Contractor. Our unique staffing often allows us to correct problems before the public starts making complaint phone calls to City staff.
