Abstract: Traffic congestion and environmental pollution are becoming severe in developing countries with increasing mobility and intense vehicle usage. An attempt is made on finding effective transport policies to alleviate the problems. Policy issues focus mainly on “push and pull” strategy using a road-pricing scheme together with fare reduction of public transportation. The suggested road pricing scheme treats CBD and inner suburb zones with different charges, especially for car and motor cycle travel. In addition, it considers three different time spans such as restricted, partly restricted and free entry basis corresponding to the peak congestion periods. A multi-level Nested Logit (NL) model is initially developed to capture the recent variations of household decisions on vehicle usage, mode choices and trip chains in daily commuting for two-traveler households. Developed model is then applied for policy analysis, using Bangkok Metropolitan Region (BMR) as a case study.
