| 摘 要： | 讨论了适于估计起迄点出行分布矩阵(OD矩阵)的交通检测点的合理分布问题.根据检测点应当满足的规则,建立了关于检测点分布的非线性规划模型.在已知极点问转移概率的前提下,将检测点的分布问题描述成一个平均报酬Markov决策过程,并通过转化为一个等价的整数线性规划问题来求解.最后实例结果表明该模型是有效的、合理的.

| Abstract: | This paper discusses how to determinethe optimal number and locations of traffic counting points in a road network forestimating the origin-destination trip matrix. Based on location rules, a nonlinearprogramming model for determining the optimal locations of traffic counting points isaddressed under a given OD distribution pattern. Such problem can also be described as anaverage reward Markov decision process (MDP) with additional constraints, which can beequivalent to an integer linear programming problem. The computational example shows thatthe results obtained are satisfactory. |
