【摘要】：伴隨國民經(jīng)濟(jì)的迅速發(fā)展,高速公路車流量日益增加,監(jiān)控系統(tǒng)在保障高速公路交通安全中發(fā)揮著越來越重要的作用。但是在過去相當(dāng)長的一段時期內(nèi),高速公路交通監(jiān)控外場設(shè)備布置主要依據(jù)寬泛的和粗放的國家規(guī)范,因此監(jiān)控外場設(shè)備資源已經(jīng)無法滿足當(dāng)前交通監(jiān)控需求。高速公路交通安全的高要求與監(jiān)控外場設(shè)備資源有限的矛盾日益突出,亟需研究一種對高速公路監(jiān)控外場設(shè)備資源合理、優(yōu)化配置的方法,以提高監(jiān)控滿足量值。 現(xiàn)有研究多數(shù)僅以單一監(jiān)控外場設(shè)備選址來進(jìn)行該監(jiān)控外場設(shè)備布置研究,忽略了從整體以及交通安全影響因素綜合考慮監(jiān)控外場設(shè)備資源的配置問題。本文在國家監(jiān)控規(guī)范的基礎(chǔ)上,運(yùn)用事故致因理論、層次分析法,提出了基于監(jiān)控源評價兩級權(quán)重體系的監(jiān)控外場設(shè)備資源優(yōu)化配置方法,建立了具有普適性的模型,并最終應(yīng)用遺傳算法進(jìn)行模型的求解,以得到優(yōu)化配置方案,從而提升了高速公路的監(jiān)控滿足量值。 本文以北京五環(huán)繞城高速VMS為例進(jìn)行了模型的驗(yàn)證分析,結(jié)果表明本文提出的模型很大程度上可以改善高速公路監(jiān)控外場設(shè)備資源的配置現(xiàn)狀,在不增加成本的前提下,充分利用了監(jiān)控外場設(shè)備,以更好的實(shí)現(xiàn)監(jiān)控交通狀況。本文旨在通過這樣的模型和驗(yàn)證為交通部門配置監(jiān)控外場設(shè)備資源時提供一定的參考和依據(jù)。
[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.
