Chair: Yafeng Yin Major: Civil Engineering Since its inception over 90 years ago, congestion pricing has been recognized by many as an efficient method for alleviating traffic congestion. Despite the successes of pricing projects worldwide and growing government support, congestion pricing remains largely unappealing to the general public, and it is this lack of public support that impedes its further development and implementation. This dissertation focuses on a class of congestion pricing

It is believed that such pricing strategies should be able to gain more public acceptance. This dissertation provides an in-depth investigation of the-state-of-the-art of Pareto-improving pricing strategies for general transportation networks. First, a systematic study of the existence and properties of Pareto-improving pricing schemes is conducted. Second, an anonymous Pareto-improving pricing scheme in a transportation network with a discrete set of value of times (VOTs) for several distinct user classes is proposed and solution algorithms are developed to solve the proposed model efficiently. Last, a Pareto-improving hybrid policy that combines multiple policy instruments is investigated. The proposed hybrid policy takes advantage of the synergistic effects between congestion pricing and free-travel-right assignment. Numerical results demonstrate that the proposed hybrid policy can achieve substantial improvements in transportation system efficiency while maintaining Pareto-improving.
