【摘要】：城市化的高級階段帶來人口和機動車的過度增長,使得城市交通擁堵嚴重。政府擬通過大力發(fā)展公共交通來緩解交通擁堵問題。隨著區(qū)域內(nèi)經(jīng)濟社會與公共交通的日趨成熟化發(fā)展,常規(guī)公交發(fā)展較為完善,覆蓋范圍較廣,但運營過程中故障時有發(fā)生,一方面對公交車輛運營造成影響,另一方面也容易帶來部分路段交通堵塞,引發(fā)二次事故。因此,本文對公交車輛應急救援服務點的合理配置和布局進行研究,通過利用現(xiàn)有資源,調(diào)配救援設施設備及人員,合理布局服務點。通過體系化地研究公交車輛應急救援服務點布局問題,以便最大程度提供良好的救援服務,提升響應速度,盡可能減輕公交車輛故障與事故的影響,對提升城市交通應急保障能力有重要意義。論文在分析國內(nèi)外選址理論及相關應急救援服務理論的基礎上,分析了公交車輛發(fā)生交通故障的類型、發(fā)生地點的類型、不同車型發(fā)生故障的情況,總結了公交車輛交通故障的特點,并對應急救援體系進行了評述,提出了目前我國公交應急救援體系運行現(xiàn)狀以及存在的問題。論文通過構建相應的救援網(wǎng)絡,確定路段路權、節(jié)點權重、網(wǎng)絡路徑,研究了公交車輛應急救援服務點選址的問題。本文對選址問題的一般模型,如覆蓋模型、P-中值模型、P-中心模型等進行評估分析,結合文中服務點選址思路與原則,考慮影響選址的多個因素,構建多目標模型應用于公交車輛應急救援服務點選址問題。通過確定算法求解方案,并選取達州市公交線網(wǎng)作為實例進行研究,驗證該理論研究應用于實際服務點選址問題的可行性,為決策者提供依據(jù)。
[Abstract]:The advanced stage of urbanization brings the excessive growth of population and motor vehicles, and makes the urban traffic jam serious. The government plans to ease traffic congestion by vigorously developing public transport. With the development of economy, society and public transportation in the region, the development of conventional public transport is more perfect and covers a wide range, but faults occur frequently in the operation process, on the one hand, it has an impact on the operation of public transport vehicles. On the other hand, it is easy to bring part of the road traffic jam, causing a second accident. Therefore, this paper studies the reasonable allocation and layout of emergency rescue service points for public transport vehicles. By utilizing existing resources, deploying rescue facilities, equipment and personnel, reasonable layout of service points is carried out. Through systematical research on the layout of emergency rescue service points for public transport vehicles, in order to provide the best rescue service to the maximum extent, improve the response speed, and minimize the impact of bus failures and accidents as far as possible. It is of great significance to enhance the ability of urban traffic emergency support. Based on the analysis of the theory of location selection at home and abroad and the theory of emergency rescue service, the paper analyzes the type of traffic failure, the type of location, and the failure of different types of vehicles. This paper summarizes the characteristics of the traffic failure of public transport vehicles, comments on the emergency rescue system, and puts forward the present operating status and existing problems of the public transport emergency rescue system in China. By constructing the corresponding rescue network, determining the road right, node weight and network path, this paper studies the location of emergency rescue service points for public transport vehicles. In this paper, the general model of the location problem, such as the covering model, the median model and the P- center model, is evaluated and analyzed. Combined with the thought and principle of the location of the service point in the paper, several factors affecting the location are considered. A multi-objective model is constructed to solve the problem of bus emergency rescue service location. By determining the solution scheme of the algorithm and selecting Dazhou bus network as an example, the feasibility of applying the theoretical research to the practical service point location problem is verified, which provides the basis for the decision makers.
