第二届交通科学与计算专题研讨会报告摘要 1 大会特邀报告： Numerical Methods for Traffic Flow Models Chi-Wang Shu Division of Applied Mathematics Brown University Traffic flow models, including vehicle flow models and pedestrian flow models, often involve complicated, coupled systems of hyperbolic partial differential equations, including hyperbolic conservation laws and Hamilton-Jacobi equations. In this talk we discuss several issues encountered in numerical simulations of these traffic flow models. Topics to be covered include: (1) Conservation laws involving discontinuous fluxes; (2) Lax-Wendroff type boundary treatment for fast sweeping method solving static Hamilton-Jacobi equations using high order WENO schemes; (3) Numerical solutions coupled systems of forward-in-time conservation laws and backward-in-time Hamilton-Jacobi equations. Simulation results will also be presented to demonstrate the performance of the numerical algorithms. 大会特邀报告： Present, Future and New Transportation Keechoo Choi TOD-based Sustainable City Transportation Research Center Department of Transportation Systems Engineering Ajou University Opening with the concept of transportation, author will present the current status quo of transportation together with future vision of transportation in our society. More specifically, in this presentation, new forms of technologies and paradigms to combat congestion, accident, and environmental degradation will be featured with some concrete examples from pedestrian walking to high speed rail. The integration of humanities an
