英文摘要： Road network is inherent stochastic dynamic, describing this character detailedly is helpful to obtain more realistic and practical design scheme for real road network's traffic situation, and can also provide stratagem basis and theory support for road network's real-time management and control. This project is aimed to solve network design problem under stochastic dynamic condition. The theories and methods including proposal theory, vulnerability analysis and robustness optimization are adopted for research. This project can reveal stochastic dynamic character of transportation system, improve network operation efficiency and has important theoretical value and wide application prospect. The main contents of this project are as follows: first, building a dynamic traffic assignment model based on cumulative proposal theory to describe travel behavior and network's traffic state under stochastic dynamic condition; then, establishing integrated vulnerability indexes to evaluate road network's stochastic performance and at last establishing a robustness optimization model for network design under stochastic dynamic condition and analyzing the solution methods.
