Traffic Impact Studies

Traffic Impact Studies (TIS) are one component of a total transportation solution for today’s complex projects. We are experienced in developing project support through effective public involvement on traffic issues. Traffic analysis and engineering studies give the big picture of traffic conditions by considering elements like traffic volumes, intersection geometrics, and operations.  We use current technologies for analysis such as traffic micro-simulation to accurately reflect real-word conditions. Our traffic planning, parking, and calming studies provide the understanding needed when road rework or development projects will increase traffic volumes or modify traffic patterns.

Clients such as state transportation agencies and municipal governments use our Traffic Signal System Design, Analysis, and Optimization for intersection traffic control studies to optimize signal timing to improve traffic flow and reduce delays.  We implement state-of-the art hardware and software–in-the-loop simulation technology to provide detailed analysis results.

Pedestrian and Bicycle Studies

In addition to vehicular traffic, pedestrian and bicycle analysis is also necessary to the design of integrated transportation systems.  Our studies have identified successful strategies to promote alternative transportation and improve safety for pedestrians.

We have developed community comprehensive action plans by providing specific engineering, planning, enforcement, and education recommendations to promote pedestrian and bicycle safety. One analysis on the safety effects of the Leading Pedestrian Interval (LPI) and its results was presented at the Penn State Transportation Engineering and Safety Conference (2008) and at the 2009 Annual meeting of the Transportation Research Board (TRB) in Washington,D.C.  The report was selected for publication in the Transportation Research Record Journal.
