| 摘 要： | 建立了一种模拟高速公路交通事故和干涉车流波的非线性交通流数学模型，并采用二阶精度无振荡差分格式对其求解。算例显示能够模拟高速公路交通事故引起的冲击波的传播过程，模拟干涉作用所引起的冲击波对排队消散的影响过程。所得结果比线性交通流模型更加丰富。

| Abstract: | A kind of non-linear traffic flow mathematical modeling to simulate the expressway incident and the intervention traffic waves is presented with non-oscillatory and second-order accuracy finite difference scheme to solve it. Numerical examples show it is suitable for the spread of shock way resulted from expressway incident and the effect procedure of queue dissipation as a result of intervention. The results obtained here are richer than the ones from linear traffic flow model. |
