Fisher Associates – Signal Coordination Study

As a leading independent professional liability insurance brokerage offering customized civil engineers errors and omission insurance policies and risk management solutions, our team at Fenner & Esler is proud to showcase the projects and successes of our clients.    

The $400,000 signal coordination study conducted by Fisher and Associates improved efficiency and safety for the traveling public. Signal Optimization, a Transportation System Management (TSM) tool was used to maximize roadway mobility, capacity, and efficiency without capital construction improvements. Traffic Signal Coordination Studies were provided for multiple corridors where optimized timings provided significant traffic flow improvements with typical Benefit/Cost ratios of 70+ and $1,200,000 per corridor yearly savings in reduced travel times, delays, stops, emissions, and gas consumption.

Traffic Signal Coordination Studies were provided for six major corridors with 142 signals for the City of Buffalo and NYSDOT.  Traffic and geometric data was inventoried to developed three coordination timings for each of the systems. Work elements involved data collection, system timing plan development (cycle lengths, phasing, and timing), signal pre-empt timing development, development of controller input files, analysis of existing operations using Synchro TrafficWare,and before/after evaluations involving speed/delay runs. Signal optimization provided planning information and development/implementation of corridor-wide signal control systems.

The goals and objectives are compatible with the initiatives set forth in New York Statewide Transportation Master Plan to provide:

* Mobility and Reliability
* Improve Air Quality
* Environmental Improvement
* Economic Sustainability and Competitiveness
* Improve Safety
* Maximize existing roadway capacity without costly capital investments

The Signal Coordination Corridors addressed in this study included:

* Clinton Street (Michigan to City Line), 25 signals
* Elmwood Avenue (Tupper to City Line), 39 signals
* Main Street (Goodell to Humboldt), 19 signals
* Sheridan Blvd. (Grand Island Blvd to N. Forest), 25 signals
* Niagara Falls Blvd. (Eggert to County Line), 25 signals
* Main Street (Bailey to I-290), 15 signals
