We performed traffic and parking impact analyses for 24 intersections and roadway segments under existing and future conditions, and we identified and evaluated traffic capacity improvement measures for the mitigation of significant impacts, as well as gameday traffic management improvements to maintain safe and efficient vehicular and pedestrian flows. Our staff conducted all traffic analyses in accordance with Highway Capacity Manual procedures, and we also developed detailed CORSIM traffic simulation models for the analysis of Major Deegan Expressway roadway segments. New travel mode, origin-destination, and parking utilization surveys were used to project traffic and parking conditions under the proposed plan.

Another key element of our analysis was an assessment of the adequacy of the access/egress configuration of all four proposed garages, including detailed queuing analyses to predict potential backups onto the adjacent street network for peak pre- and post-game conditions. We participated in public hearings, presentations, and interagency coordination meetings, and wrote the “Traffic and Parking” chapter of the draft and final environmental impact statements. The New York City Department of Parks and Recreation issued a Notice of Completion for the final generic environmental impact statement in February 2006, and the stadium opened in time for the 2009 Major League Baseball season.
