Optimal Design of a Financial Sustainable HOT Network

项目名称：	Optimal Design of a Financial Sustainable HOT Network
摘要：	This project proposes to develop methods for sequentially building networks of high occupancy toll (HOT) lanes, with objective of achieving system efficiency, social equitability, and financial sustainability. A mathematical model that integrates multistage decision processes, optimization techniques, and user behavior model will be developed to identify the optimal sequence of converting existing and under-construction HOV facilities to HOT lanes and the associated pricing strategies. Various system performance measures will be considered including total toll revenue, total vehicle delay, and total costs for the users. The requirement on equitability, measured by the gap between the rich and the poor in terms of benefits from the implementation of HOT lanes, is explicitly included as model constraints to ensure a solution that is more likely to be accepted by all income groups. The multistage framework allows optimal usage of toll revenue gained from implemented HOT segments for financing future HOT projects, thus imposes less financial burden on public agencies and future generations. These unique modeling treatments are proposed to enhance the overall sustainability of the transportation network in question. Case studies based on selected corridors in San Francisco Bay Area will be carried out for numerical testing, sensitivity analysis of model parameters, and policy implications.
