【摘要】：伴随国民经济的迅速发展,高速公路车流量日益增加,监控系统在保障高速公路交通安全中发挥着越来越重要的作用。但是在过去相当长的一段时期内,高速公路交通监控外场设备布置主要依据宽泛的和粗放的国家规范,因此监控外场设备资源已经无法满足当前交通监控需求。高速公路交通安全的高要求与监控外场设备资源有限的矛盾日益突出,亟需研究一种对高速公路监控外场设备资源合理、优化配置的方法,以提高监控满足量值。现有研究多数仅以单一监控外场设备选址来进行该监控外场设备布置研究,忽略了从整体以及交通安全影响因素综合考虑监控外场设备资源的配置问题。本文在国家监控规范的基础上,运用事故致因理论、层次分析法,提出了基于监控源评价两级权重体系的监控外场设备资源优化配置方法,建立了具有普适性的模型,并最终应用遗传算法进行模型的求解,以得到优化配置方案,从而提升了高速公路的监控满足量值。本文以北京五环绕城高速VMS为例进行了模型的验证分析,结果表明本文提出的模型很大程度上可以改善高速公路监控外场设备资源的配置现状,在不增加成本的前提下,充分利用了监控外场设备,以更好的实现监控交通状况。本文旨在通过这样的模型和验证为交通部门配置监控外场设备资源时提供一定的参考和依据。
[Abstract]:With the rapid development of national economy, the traffic volume of expressway is increasing day by day, and the monitoring system plays a more and more important role in ensuring highway traffic safety. But in the past quite a long period of time, the expressway traffic monitoring outfield equipment layout mainly according to the broad and extensive national norms, so the monitoring field equipment resources can not meet the current traffic monitoring needs. The contradiction between the high requirement of expressway traffic safety and the limited resources of the monitoring field equipment is becoming more and more serious. It is urgent to study a method of rational and optimal allocation of the equipment resources for the expressway monitoring field in order to improve the value of the monitoring and control. Most of the existing studies only use the location of the monitoring field equipment to study the location of the monitoring field equipment, neglecting to consider the allocation of the monitoring field equipment resources comprehensively from the whole and the traffic safety influence factors. In this paper, based on the national monitoring standard, using accident cause theory and analytic hierarchy process (AHP), a method of optimal allocation of monitoring field equipment resources based on the two-level weight system of monitoring source evaluation is proposed, and a universal model is established. Finally, genetic algorithm is used to solve the model to get the optimal configuration scheme, which can improve the quality of highway monitoring and control. In this paper, the model is verified and analyzed with the example of Beijing Wuhuan High-speed VMS. The results show that the proposed model can improve the present situation of equipment resource allocation in expressway monitoring and control field to a great extent, without increasing the cost. Full use of field monitoring equipment to better monitor traffic conditions. The purpose of this paper is to provide a certain reference and basis for the traffic department to configure the monitoring field equipment resources through this model and verification.
