| 摘 要： | 交通量是交通密集度和速度的函数,从交通流流量-速度-密集度的动态特性分析人手,运用分子动力学,定性分析车队中车辆的运动趋势对交通量-密集度的影响,建立基于分子动力学的车流密集度模型,并进行交通流特性分析.研究结果表明,要使交通量达到最优,则道路车流密集度应该保持在临界密集度附近.

| Abstract: | It has scientifically proven that traffic flow is a function of traffic density and speed, and therefor analysis of the dynamic characteristics of the traffic flow, rate, density by using molecular dynamics is carried out. The qualitative analysis in the vehicle＇s movement trend influence on traffic flow, density, traffic density model of molecular dynamics is set up, and analysis of traffic flow characteristics is made. The result shows that if the optimal traffic flow is to be attained, the road traffic density will be near the critical density. |
