A model endeavor: Improving traffic microsimulation

摘要

A public-private partnership is working to bring better traffic microsimulation technology to market in the form of NGSIM. Ultimately, these enhanced virtual tools will facilitate better transportation decision-making. Traffic analysts today are faced with evaluating diverse and complex solutions to address congestion in transportation systems. Instead of 'simply' deciding how many lanes to design for a new freeway or how long the turn bays should be at a traffic signal, practitioners are analyzing advanced traffic signal and ramp metering systems, for example, and complex weaving and geometric configurations, ITS strategies, multimodal corridor management plans, and congestion pricing strategies.
