运用ArcGIS完成了道路交叉口的成图。经过道路车流量的统计与分析,总结出了道路车辆的出行规律。最后构建道路车辆通行模型,完成了按需配时红绿灯指挥模型的构建与解算

摘 要如今交通问题日益严重,解决交通堵塞问题迫在眉睫。虽然目前的交通信号灯在一定程度上维护了交通秩序,但是存在着很大的问题,为了给交通信号灯制定出更加合理的时间分配方案,进行了这次基于物联网技术的车辆智能指挥系统研究。物联网技术是一种能够使物物相连、物物可管、统筹分配资源的技术。本次研究实地调研了道路交叉口类型及参数,运用ArcGIS完成了道路交叉口的成图。经过道路车流量的统计与分析,总结出了道路车辆的出行规律。最后构建道路车辆通行模型,完成了按需配时红绿灯指挥模型的构建与解算。经过对比分析,研究结果得出使用本文研究的系统可以提高交叉口道路通行能力,基于路况或未来物联网的道路交叉口车辆指挥系统,比传统系统拥有更好的指挥效果,是智能车辆指挥系统未来的发展方向。31564

 Abstract
Nowadays the traffic problem is getting more and more serious, solving this problem is extremely urgent. Although the current traffic lights maintain the traffic order to some extent, there is something wrong with it. In order to develop a plan which allocates time more reasonably for traffic lights, I do a study based on the vehicle intelligent command system using the technology of Internet of things. The Internet of things technology is a kind of technology to establish a connection among things and things and manage things, distribute resources as a whole. A field survey was carried out to get the types and arguments of road intersection. Then I use ArcGIS to complete the figure of road intersections. Through statistics and analysis of road traffic, I summarize the travel law of road vehicles. Finally I built a road traffic model and completed the on-demand distribution when the traffic lights command model building and calculating. Through comparison and analysis, I concluded that using the plan in this paper can greatly improve the intersection traffic capacity. The system based on the road or Internet of things in the future will better than the traditional on traffic. Moreover the command of the intelligent vehicle command system is the development direction of the future. 源`自*六)维[论*文'网www.lwfree.cn
