相邻信号交叉口间路段的交通空间容量

Traffic Space Capacity of Road between Neighboring Signal Intersections

定义了良性车辆最多状态 ,从城市道路的关键点———交叉口出发 ,在假定车辆速度服从正态分布的前提下 ,推导了单车道的良性最多车辆数公式 ,并将这个复杂的公式制成了可实用的表 .在此基础上 。

The status of proper maximum-vehicles is defined.Take the traffic property of intersection as basis,the formula of proper maximum number of vehicles is posed,provided the speeds of vehicles submit to the normal probability distribution.The complicated formula is simplified to a table.On this basis,the models of traffic space capacity of the road between neighboring signal intersections are researched,respectively to the situations of mono-lane and multi-lane.
