【摘要】：随着居住区居民户均小汽车数量的增加,居住区内交通运行不通畅和交通设施不完善等问题日益严重。在居住区现有道路和停车空间等资源条件下,分析居住区出入口、道路横断面设计和地面停车等问题,合理选择对居住区主要交通设施的改善方案,协调居住区内道路通行能力和宜居环境之间关系,对于提高居民生活质量有十分重要的意义。为实现此目标,本文主要研究内容和结论如下： (1)依据居住区交通设施建设现状,详细分析了居住区出入口、道路系统、停车设施和其它稳静化设施的布设要求。并且通过实地调研数据和国外案例,分析现有布设要求的局限性。 (2)对居民交通出行特性进行了阐述,分析了居住区机动车、非机动车和行人混行的交通系统运行特点,总结出居住区区别于公共道路交通最主要的特性是通而不畅,机动车需在保证行人优先权和宜居生活环境的基础上提高通行效率。 (3)根据居住区现状问题,给出选定情景下出入口布设、道路横断面设计和停车设施布设的改善方案。改善方案主要包括改变出入口宽度和设置形式；细化不同交通量和出行结构条件下道路横断面设计方法；选择不同道路等级路面停车泊位形式,并结合道路交通组织流线变化,解决占道停车问题等。 (4)对改善方案进行仿真,由居住区布设现状和实地调查情况,确定不同情景中驾驶行为、交通构成和路径决策等参数,输出延误时间、排队长度、车速和车流量等评价指标结果。根据评价指标结果,分析各情景下改善方案的优缺点。
[Abstract]:With the increase of the number of cars per inhabitant in residential area, the traffic and transportation facilities in residential area are not smooth and perfect. Under the existing resources such as roads and parking space in residential area, the problems are becoming more and more serious. The problems of entrance and exit, cross section design and ground parking of residential area are analyzed, the improvement scheme of main traffic facilities in residential area is reasonably selected, and the relationship between road capacity and livable environment in residential area is coordinated. It is of great significance to improve the quality of life of residents. In order to achieve this goal, the main contents and conclusions of this paper are as follows: 1) according to the present situation of traffic facilities construction in residential area, the layout requirements of entrance and exit, road system, parking facilities and other stabilization facilities in residential area are analyzed in detail, and through field investigation data and foreign cases. The limitations of the existing layout requirements are analyzed. This paper expounds the characteristics of residents' traffic travel, and analyzes the operating characteristics of the traffic system of motor vehicles, non-motor vehicles and pedestrians in residential areas. It is concluded that the most important characteristic of residential area differs from public road traffic is that it is not smooth, and motor vehicles should improve traffic efficiency on the basis of ensuring pedestrian priority and livable environment. (3) according to the present situation of residential area, the improvement scheme of entrance layout, road cross section design and parking facility layout under the selected situation is given. The improvement scheme mainly includes changing the width and setting form of entrance and exit. The design method of cross section under different traffic volume and travel structure; Choosing the parking berth form of different road grade and combining with the road traffic organization streamline change to solve the parking problem of occupation road and so on. Simulation of the improvement scheme, from the residential layout status and field investigation, determine the driving behavior in different scenarios, traffic composition and path decision-making parameters, output delay time, queue length. According to the results of the evaluation index, the advantages and disadvantages of the improvement scheme under different scenarios are analyzed.
