城市道路交通微观仿真系统的研究与设计
字数：
在道路地图上加入智能车辆（是车流，而不是一辆车），并使其顺利运行（有2条道路，仿真运行时是可以选择路线的）。智能车辆的运行参数，诸如速度,加速度要能接受GPS传来的数据，并按照其参数运行。地图中我没有加入交通信号灯，所以你们要加入，车辆在交叉口时按照交通信号灯规则运行。车辆的起点是地图中的三康庙，终点是火车站。
在对话框的顶部加入菜单栏，在把现在对话框右边的按钮移到菜单栏中，利于添加子菜单，这样对话框看起来也美观大方。
本课题主要是从微观角度出发，在现有的城市交通状况下选择有代表性的道路，依据交通流理论，以及国内外交通学者对道路交通微观仿真模型的研究成果。应用系统仿真技术、面向对象分析与设计方法，及实际GPS数据建立城市道路交通系统各个要素的模型，并在VC平台上微观仿真城市道路交通，从程序上实现微观交通流的二维仿真，实现车—路—体的微观交通仿真系统。本课题的研究路线见下图。城市道路微观交通仿真系统的模块设计：

Urban Road Traffic Micro-Simulation System Study and Design
Words:
On the road map, the smart vehicle (a flow of traffic, rather than a car), and make it a smooth running (there are two roads, run-time simulation can choose to route). Intelligent vehicle operating parameters, such as velocity, acceleration must be able to receive GPS data transmitted, and in accordance with its parameters to run. The map I have not joined the traffic lights, so you want to join the vehicle at the intersection when the traffic signal in accordance with rules. Vehicles starting point is the map of the three health Temple, the ending point is the railway station.
In the dialog box at the top of the menu bar to join in the dialog box is now moved to the right of the buttons in the menu bar, which will help to add sub-menus, dialog boxes seem so nice.
This issue mainly from the microscopic point of view, the existing urban traffic conditions selected and the road, according to traffic flow theory, as well as domestic and international transportation experts on road traffic micro-simulation model of the research results. Application system simulation technology, object-oriented analysis and design methods, and the actual GPS data to establish the various elements of urban road traffic system model, and the VC platform, micro-simulation of urban road traffic, from the program to achieve two-dimensional microscopic traffic flow simulation, achieve the car - Road - the body microscopic traffic simulation system. The subject line of research see the figure below. Microscopic traffic simulation system of urban road module design:
• Traffic Map Module
• Intelligent Vehicle Modules
• Transport module section starts
• Intelligent Vehicle Motion Module
• Traffic Light Module
• Timer-Timer Module
4. The research of technical routes, difficulties and feasibility of
4.1 The key technical line
1. In the city of the road network construction, the use of computer-aided design (AutoCAD) technology for the mapping traffic maps.
2. In the simulation technology, the VC + + build environment, the establishment of intelligent vehicle modules, transport cross-section start module, intelligent vehicle operation module, traffic signal modules and Timer-timer module.
4.2 Research Difficulties
1. How VC interface display of urban road traffic maps.
2. How do I join the intelligent vehicle on the road and make it running smoothly.
3. How to make intelligent vehicle taken in accordance with GPS data (such as speed, acceleration, etc.) run on the road.
