【摘要】：随着城镇化进程的推进,我国城市交通事业迎来了发展机遇,但同时也面临着巨大的挑战。交通需求不断增长,城市道路不堪重负,国内各大城市的道路拥堵问题愈演愈烈。公共交通作为一种运载量大、节能的出行方式,是提高公交系统服务水平、增强公交竞争力的关键所在,近年来公交优先被我国列入重点发展国策之一。国内外公交优先技术研究成果众多,种类繁多,但技术之间可自由结合亦可分别应用的较少,在针对我国公交运营特点上尚有不足之处,公交干线道路作为公交系统运营的核心所在,如何提高干线道路的公交运营效率仍然值得深入研究。本论文依托国家高技术研究发展计划(863计划)课题“交通状态感知与城市干线公交通行保障”,结合软件仿真,围绕干线道路公交优先技术开展了以下几方面的研究：首先,基于数解法绿波计算模型,运用时空等价转换理论,针对公交车行驶特性建立多交叉口分段绿波公交优先联动控制模型,根据道路实际情况求解最优信号周期参照值,计算等值路段行程时间,设置绿波带最大宽度目标函数并求解干线各交叉口绿波信号配时及最优路段公交行驶车速,并建立车辆诱导信息反馈机制。其次,设立公交优先检测装置布设方法,并在交叉口设置信号控制机,在公交车内安装信息传输装置,以公交车行驶状态检测技术和信息实时传输技术为基础,提出了多公交车申请下信号优先顺序确定方法和公交优先信号确定方法,在各相位开始前,对所有优先车辆进行等级排序并调整未来相位的信号时长,最后将优先结果反馈至各公交车。再次,根据我国城市公交线路布设特性和公交车运营特性,建立了考虑多公交车共线的最优发车时间间隔计算方法,以乘客利益、环境利益最佳为目标函数并设立限制条件,求解公交车最优发车间隔作平峰时段发车参考；并根据公交车高峰时刻运营特性,提出了公交车高峰时段运营调度方法。最后,以佛山岭南大道、汾江路两条道路基础数据为基础,运用VISSIM微观仿真软件对多交叉口分段绿波公交优先联动控制模型、多公交车优先通行请求冲突的协同控制模型相关技术进行仿真模拟,并选取关键指标进行定量评价。此外,通过实地调查获取数据,对公交车始末站发车控制模型进行实例计算并比对使用效果。
[Abstract]:With the advance of urbanization, China's transportation city ushered in development opportunities, but also faces enormous challenges. The growing demand for city road traffic, road congestion problems overwhelmed, the domestic each big city intensified. Public transport as a large carrying capacity, energy-saving way to travel, is to improve the public transport system service the level of enhancement of key competitiveness in recent years, the bus, the bus priority was included in China's focus on the development of national policy. The domestic and foreign research results of many bus priority technology, variety, but the technology between self were used by combining also less in our country according to the characteristics of bus operators are still inadequate, the bus route as the core transit system operation, how to improve the operational efficiency of bus route are still worthy of further study. This paper is based on the national high technology research and development Plan (863 plan) project "traffic perception and city transit trunk security", combined with software simulation, around the trunk road bus priority technology to carry out research on the following aspects: first, the number of green solution calculation model based on space-time equivalent transformation theory, aiming at the characteristics of bus travel establish multi intersection bus priority segment greenwave linkage the control model, the reference value according to the actual situation to solve the optimal path of the signal cycle, calculation of equivalent travel time, with the maximum width of the objective function and solving the trunk of each intersection green wave signal with set and optimal road bus green wave speed, and the establishment of vehicle guidance information feedback mechanism. Secondly, the establishment of the bus priority detection device and layout method. The control signal is arranged in the intersection, the installation information transmission device on the bus, the bus driving status detection technology and the letter Real time information transmission technology, presents a multi bus signal priority for order determination method and bus priority signal in each phase before the start of the ranking of all priority vehicles and adjustment of the phase signal when the length of the future, the priority results feedback to each bus. Again, according to our city bus the bus line layout characteristics and operational characteristics, considering optimal departure time interval bus collinear calculation method, to the interests of passengers, the best environmental benefits as the objective function and the establishment of conditions, solving optimal bus interval for the peak period grid reference; and according to the peak time of bus operation, put forward peak operation scheduling method of bus. Finally, in Foshan south of the Five Ridges Road, Fenjiang Road, two road based data, using the VISSIM micro simulation software for multi The intersection of bus priority segment green wave linkage control model, multi bus priority request conflict coordination control model simulation technology, and select the key index for quantitative evaluation. In addition, data obtained through field investigation, to calculate and use the bus station through the alignment effect control model.
