摘要
为了及时发现和动态预警城市路网交通拥堵态势,研究了城市交通拥堵态势的动态跟踪问题。针对城市路网交通拥堵问题,利用多维联系数理论进行了研究。在对交通拥堵的相关属性、变化规律、空间分布以及判别方式等进行综合分析的基础上,探讨了城市交通拥堵在路网上的形成机理;并根据城市路网交通拥堵特性和影响因素,建立了城市路网交通拥堵监控指标体系,然后利用多维联系数理论,在确定评估等级的基础上,建立了基于多维联系数理论的城市路网交通拥堵态势监控模型,最后进行了实例分析。结果表明:该方法具有较好的可操作性,能够为城市交通拥堵疏导决策支持系统的实际开发提供理论基础。
For timely finding and dynamic warning of traffic congestion state in urban road network, the dynamic tracking of traffic congestion in urban road network was analyzed. And the problem of traffic congestion in urban road network was studied with multi-dimension connection number. Based on the comprehensive analysis of relevant attributes, changing regulation, space distribution and discrimination method of traffic congestion, the authors analyzed formation mechanism of traffic congestion in urban road network. Based on the analysis of traffic congestion characteristics and influence factors, a monitoring index system of traffic congestion in urban road network was presented. Based on the determination of the assessment levels, the monitoring model of urban traffic congestion was designed with multi-dimension connection number. The validity of the model was checked at the end. The results have revealed the validity and maneuverability of the study, and thus a theory foundation for developing the decision support system for urban traffic congestion management is provided.
