Tehran MID-term transportation and traffic studies

摘要

Tehran Comprehensive Transportation and Traffic Studies began in 1994 with the collection of socioeconomic data, network characteristics, public transit data, and pertorming trip surveys and traffic volume counts. Trip generation, trip distribution, and mode choice models were calibrated using these data regarding the size of Techran and consequently its database, and also the details aimed for in these studies. EMME/2 was selected as the appropriate software tool for demand prediction and traffic assignment. Tehran transportation modeling underwent two principle stages: a. Simulating the current state; b. Future prediction and optimizing transportation system through defining and evaluating alternatives. Following steps were taken in the transportation modeling using EMME/2: a. Trip generation forecasting; b. Trip distribution forecasting; c. Mode choice forecasting; d. Forecasting cordon trips and goods transportation; e. Combining trip matrices for each mode; f. Segregating trips by modes allowed into the CBD from those by other modes.
