【摘要】：“十三五”是我国发展“一带一路”战略的关键时期,新疆是实施我国“一带一路”战略向西发展的重要走廊及窗口,也是实现“总目标”的主阵地。近年来,新疆各地区城市化进程加快,已促使各市、县群众出行和货物运输频次徒升,城市各类交通流量持续增大,也伴随交通拥堵、交通事故和交通混乱等三大热点、难点问题的出现,当前开展城市交通改善规划和设计研究及改造建设工作尤显迫切。各市中心城区及各县县城等城市交通信号控制平交口是城市路网中各类交通流变化的敏感反应区和当地交通状态优劣的关键评价区,对信控平交口开展交通改善研究工作是开展城市交通系统改善的重点,其中对普遍使用的单点定时控制系统的信控配时设计与有效实施是研究的难点问题[1]。由于新疆各市、县城市道路交通特性有异于我国内地和国外城市交通特性,城市信控平交口交通特性也不同于我国内地和国外城市信控平交口交通特性,目前国内外对信控配时设计研究仍应用Webster理论方法,由于其主要设计过程参数来源于国外城市信控平交口交通特性,国内应用韦伯斯特Webster法在开展信控平交口配时设计后,通常要进行仿真验证并进行参数调整,过程繁杂。为探研适应于新疆城市信控平交口交通特性,能快速、精准开展信控配时设计的方法,经对新疆大学交通工程研究团队已开展的大量新疆城市信控平交口交通改善信控配时研究总结,并比对相关国家技术标准及相关研究与技术文献,本文抽取新疆典型城市信控配时相关数据,通过对车流释放过程中的相关特征参数分析,推导总损失时间、基本饱和流率、周期时长等信控配时过程关键参数,形成优化配时参数,并总结出一套基于渠化设计与信控设计并举的综合设计方法。
[Abstract]:"13th Five-Year" is the development of our country "The Belt and Road" strategy of the critical period, Xinjiang is an important window of corridor and the implementation of China's "The Belt and Road" development strategy to the west, but also the realization of "the main front target. In recent years, the process of the city area of Xinjiang has been accelerated, make the municipalities, county people travel and transportation frequency zoom, The traffic flow of cities is increasing continuously, with traffic congestion, traffic accidents and traffic confusion, and other three hot spots and difficult problems. It is very urgent to carry out urban traffic improvement planning and design research and reconstruction. The key evaluation area of the sensitive reaction zone and the local traffic state of the type of traffic flow is the key evaluation area. The research work on the traffic improvement is the key to the improvement of the urban traffic system. The design and effective implementation of the signal timing and effective implementation of the commonly used single point timing control system is the difficulty of the research [1]. due to Xinjiang The traffic characteristics of cities and counties are different from those of mainland and foreign cities in our country. The traffic characteristics of urban trust and control port are different from the traffic characteristics of China's mainland and foreign cities. At present, the Webster theory method is still applied to the research of the design and study of the control time, because the main parameters of the design process are from the country. The traffic characteristics of the control flat intersection of the outside city, after the domestic application of Webster Webster method in the design of the intersection of the controlled flat intersection, the simulation verification and parameter adjustment are usually carried out, and the process is complicated. In order to study the traffic characteristics of the Xinjiang city's urban trust and control port, it can be fast and accurate to carry out the design of the reliability and timing of the Xinjiang University. The traffic engineering research team has carried out a large number of research and summing up of the traffic improvement in Xinjiang city's urban trust and control port, and compared the related national technical standards and related research and technical literature. This paper extracts the related data of the typical city of Xinjiang, and deducts the total loss through the analysis of the related characteristic parameters in the vehicle flow release process. The key parameters of time, basic saturated flow rate, period length and so on are the key parameters of the timing process, and the optimal timing parameters are formed, and a set of comprehensive design method based on the design of channelization and the design of the reliability and control is summarized.
