摘要

Transport policies should ensure that a transport system could satisfy at least threerequirements. First, public and private modes should have sufficient physical capacity toaccommodate travel demand. Second, public modes should have financially viable operations.And third, there should be sufficient demand for public modes to have profitable operations.A quick-response and integrated model is developed that evaluates the effects of transportpolicies on these three requirements. The developed model defines the ranges of peak-hourCBD-bound travel demand that can be accommodated by the physical capacity of public andprivate modes and can give financial viability to public modes. Using a comparison ofgeneralized cost as basis, the model also estimates the demand for bus and car that resultsfrom transport policies; bus and car being the dominant and competing modes for CBD-boundtrips in the study area. The model results are then validated by comparing them with actualfinancial performance of public modes and with travel demand data from person trip surveysconducted in the study area. Different transport policies like subsidy, fares, and TDMmeasures are evaluated and their effects on the physical capacity, financial viability, anddemand for the modes are determined.
