In this paper, a dynamic hypothesis in the form of feedback relationship is proposed and a System Dynamics model is formulated to experiment some of commonly discussed policy alternatives. The simulation result reveals that introduction of off-road rapid transit system is important not only to maintain or regain the modal share of public transport but also to improve road traffic congestion. However, rapid transit system developed too late may bring only limited impact primarily due to unfavorable land-use condition.
