摘要
间断问题是交通流动力学模型研究中一个重要而且困难的课题 .本文运用特征线方法 ,从交通流原始守恒方程出发给出了解决弱解存在与唯一性的间断关系与熵条件 .讨论的结果不仅被直接应用于红绿灯问题 ,更重要的是它们对认识交通流间断本质具有理论意义 ,是交通流动力学模型设计与数值模拟的重要基础 .
Discontinuity is an important and difficult subject in traffic model research. By means of characteristics and based on initial conservation law, this paper discusses the existence and uniqueness of weak solution, along with its Rankine-Hugoniot and Entropy Condition. The results can be applied directly in solving the red-signal problem. Moreover, they are of theoretical significance in realizing the nature of traffic discontinuity, and therefore pave the way to the design of traffic flow models and numerical simulation.
