An Evaluation Framework for Real-Time Mode Shift Benefits Assessment

Wunderlich, Karl

A traffic simulation and a mode choice module are employed iteratively for the assessment of real-time mode shift for the reduction of traveler delay. When the modules are allowed to iterate to equilibrium under expected travel demand and network capacity, the resultant time-variant mode splits represent baseline or expected conditions. Weather or other effects may impact realized demand or capacity, however. Travelers assumed to have a trip planning user service may make mode choices based on predicted roadway trip times for their origin, destination, and time of departure. Travelers without the user service make a mode choice based solely on expected conditions. In application to a test network under predictable roadway capacity reduction, the framework demonstrates real-time mode shifting has significant potential benefits. User (real-time mode shifter) benefits and system travel time reduction are quantified for a range of potential market penetrations.
