摘 要
城市与乡镇间交通道路的建设是其区域间经济发展的重要一环,不仅是城市与乡镇道路担任着人力物资交互的职能,而且也是工业辅助农业发展,农业反哺工业的重要纽带,与城市的生产发展有着密切的关系。现如今经济快速发展,人民水平也稳固上升,从而私家车拥有量大幅度提升,相对于过去的十年里数量提升了四倍之多,这也就对城镇道路造成了更多的压力。交通需求也随着经济的发展大幅度提高,过去的交通网络服务能力已不能满足目前的交通形势。也就出现了类似交通堵塞、交通事故变多、道路两侧环境污染等等问题。这些问题的存在严重影响了城镇间健康的经济发展。交通仿真技术的出现可以提供这些问题解决方法的参考方案,相对而言,计算机仿真技术要比其它的交通分析技术具有更多更加实际性的优点。所以目前计算机仿真技术在国内外交通工程研究领域里成为热点之一。
本文主要通过熟练掌握Vissim,根据其在实际应用里稳定性和准确行,对交叉口道路段车辆拥挤情况、行程时间、行车延误、停车情况、排队时长等运用其在实际应用中的可靠性、准确性,分析周边路段及交叉口道路行程时间、平均延误、排队长度、停车次数、通行能力等指标进行评估。对目标交叉口进行建立模型,实现对道路交叉口的仿真,然后再依据指标分析道路运行情况,寻求更加优化的道路通行方案,提高道路通行能力,从而使道路管理者借此对该路口做出合理的分析。本文主要研究内容包括:
- 介绍了交通系统仿真软件及其功能,和vissim道路交叉口仿真流程。
- 城市道路交叉口数据建模与分析。
- 对南京地区典型交叉口进行交通系统仿真,预测交通延误,评估道路通行能力和服务水平。
- AE和VS环境下交叉口交通系统原型设计。

Design of Traffic Simulation System for Urban Road Intersection
Abstract
Urban road construction is an important link between cities connecting towns and industries and agriculture. It is not only the function of human and material interaction between cities and township roads, but also an important link for industry to assist agricultural development and agriculture to feed industry. The number of private car ownership of our residents has more than quadrupled in the past ten years, and the transportation demand of residents has exploded, far exceeding the existing urban transportation network service capacity. The resulting problems such as traffic congestion, environmental degradation, and increased traffic accident rates have become persistent diseases that restrict the healthy development of cities. Compared with other traffic analysis technologies, computer traffic simulation technology has many very obvious advantages. One of the research hotspots in the field.
This article mainly analyzes the indicators such as the travel time, average delay, queuing length, number of stops, capacity and other indicators of the surrounding roads and intersections by using the reliability and accuracy of Vissim in practical applications. Model the target intersection to realize the simulation of the road intersection, and then analyze the road operation according to the indicators, seek a more optimized road traffic plan, improve the road traffic capacity, so that the road manager can make use of this intersection reasonable analysis. The main research contents of this article include:
(1) Introduced the traffic system simulation software and its functions, and the vissim road intersection simulation process.
(2) Data modeling and analysis of urban road intersections.
(3) Carry out traffic system simulation on typical intersections in Nanjing, predict traffic delays, and assess road capacity and service levels.
(4) Prototype design of intersection traffic system in AE and VS environment.
