Managing the Congestion and Emissions with Road Pricing Scheme Based on Practical Case Study

Increasing traffic congestion and vehicular emissions have become a major public concern, which naturally leads to a bi-objective optimization problem, i.e., to minimize system total travel time and system total emissions. In this study, a road pricing scheme is proposed to manage the system's total travel time and total emissions simultaneously. Finally, the practical case study based on Chengdu in China is carried out to simulate a situation with the proposed road pricing. Simulation results evaluate the effectiveness of the road pricing scheme to manage the congestion and emissions.
