영문 초록

Today, most CBD areas in major cities suffer from traffic congestion, which not only causes higher travel time, but also results in worsened air pollution. Motor vehicles are the greatest single contributors to urban air pollution due to the sheer volume of their emissions per mile driven. The basic objective of this research is to develop a methodology through which both transportation network performance and urban air quality can be substantially improved. We present a mathematical programming model(Nonlinear Static Programming Model : NLSPM) that jointly minimizes transportation costs and automobile pollution impacts, using both the user-optimum and the system-optimum approach. The combined model must also properly deal with the interactions between travel time, traffic flow and speed, link capacity investment decisions, vehicle emission/diffusion, and the resulting air pollution concentrations. Based on the numerical analysis of the combined model for different Origin-Destination demands and meteorological conditions over a hypothetical network, we then figure out the social optimum level of traffic congestion and air pollution concentrations in the transpotration network.
