TVGA provided Design Phases I-VI for the reconstruction of approximately 3.4 km of state highway. As part of the project, TVGA worked with the NY State Department of Transportation, the NY State Thruway Authority, the Towns of Cheektowaga and Amherst, and the Greater Buffalo Niagara Regional Transportation Council in studying the effects of parallel corridor improvements on Harlem Road traffic patterns.
The project included numerous traffic analyses for various intersection and roadway design alternatives. Origin-destination studies were performed to identify the volume of bypass traffic within the study network. Queuing and multiple signal timing coordination and phasing scenarios were evaluated to optimize the traffic progression through the arterial. TVGA studied and analyzed nine design alternatives for an existing complex six-legged intersection. These design alternatives included evaluations for a four and five legged signalized intersection or roundabout at this location. Accident and cost/benefit analysis were also performed for the project to support the project cost in lieu of the benefits achieved. Access management techniques were utilized to prepare alternates for access improvements to minimize conflict points and allow safer and efficient traffic and pedestrian flow on the state highway.
