| 摘 要： | 运用流体力学车流波理论,分析了交通事件和干预措施综合作用下对车流状态的影响,建立了基于车速———交通密度一般模型下的车流波波速模型、干预作用产生的干预波和交通事件影响产生的集结波、启动波、消散波相互作用产生的车流波位置和对应时刻模型以及分流干预措施解除时刻模型.这些模型或关键参数的确定,为有效确定事件处理方案,尽快消除拥挤或阻塞提供了理论依据.

| Abstract: | This paper analyzed the interactive influence of traffic incidents and intervention measures on expressway traffic-flow on the base of hydrodynamic traffic-flow wave theory,established traffic-flow wave speed model,traffic-flow wave position models and corresponding time models in the interactive influence of intervention shock-wave and concentration-wave,startup-wave and dissipation-wave result from traffic incidents and relieving diffluent intervention measures time model on the base of general model of speed in relation to traffic density.Thes models or critical parameters provided the theoretical basis for determining effectively schemes for solving traffic incidents and eliminating quickly traffic congestion or clog. |
