Abstract

The city of Chicago is in the preliminary engineering final environmental impact statement phase of planning for a central area circulator system. Because of the wealth of existing bus and transit service and the amount of activity taking place in the central area, detailed modeling of transit options was required. Described here are enhancements to the transportation network coding and analysis made to travel demand forecasting models necessary to properly model the various transit options. These enhancements include determination of travel speeds on the basis of intersection control and signal timings, explicit coding of transit stops, and detailed multipath transit assignments. Finally the reasonability of applying the detailed network processing techniques in typical regional model applications is discussed.
