摘要
本文论述了到达交叉路口的车流是Poisson流的条件下,对交通灯的定时控制与随机控制进行了分析,证明在适当条件下被阻车数平稳分布存在,但不是Poisson分布,纠正了以往的结论。定时控制情形被阻车数平稳分布可用母函数表示,由此可造分布表;随机控制情形,平稳分布母函数满足一个函数方程,用它可求出各阶矩。
Under the conditions of poisson input of arrival cars, this paper gives the stationary distributions of numbers of waiting cars at the crossroads, in the control of the constant time of the traffic lights by the probability-generating functions, and in the control of the random time of the traffic lights by functional equations.
