Optimal Environmental Road Pricing

Road Dublin

  • Description:
    • The objective of this project is to model optimal environmental road pricing under different equilibrium approaches. The equilibrium approaches considered in this thesis are User Equilibrium, Stochastic User Equilibrium, and System Optimum respectively. The contribution of this project is to provide a broad study on existing equilibrium approaches to model optimal environmental road pricing. Models proposed in this project are novel and also incorporate land use-transport interaction, information provision and queuing delay simultaneously. Sensitivity analysis and multi-objective analysis on impacts of different emission pricing policies are carried out and enable the transportation planner or the decision maker to understand the benefits of different emission pricing schemes and their impacts on society, environment and transportation systems so that they can strike a balance between tradeoffs.
