The city of chicago is evaluating alternative methods for providing for the distribution of commuters to and workers, visitors and residents in the vibrant and growing central area. A detailed travel model has been calibrated to project ridership on the various circulator/distributor alternatives. The model is based on the downtown people mover system travel demand models developed for los angeles, detroit, and miami. The chicago central area and the calibration of the circulator/distributor model are described. The calibrated model coefficients are compared with the coefficients used for the los angeles, detroit, and miami models. Finally, some brief recommendations regarding future circulator/distributor model development and research efforts are presented.
