摘要
智能交通系统(ITS)是公认的缓解城市拥堵的有效手段之一,交通检测器为ITS提供交通基础数据支持。在城市路网中合理布设交通检测器是保证交通数据准确、有效的前提。以交通检测器效用最大和布设检测器费用最少为目标,构建交通检测器优化布局模型,并通过算例加以说明,为此类研究提供了一个新的思路。
Intelligent transportation system(ITS) is considered as one of the effective means of reducing urban congestion.Traffic detector supplies ITS with traffic basic data.Arranging the layout of traffic detector in urban road network reasonably is the premise for exactness and validity of traffic data.Based on the maximum utility and the minimum cost of optimal layout of traffic detector,a mathematical model of the optimal layout of traffic detector is set up.At last,an instance is presented to explain the computation process of this model.It provides a new idea for the research subject.
