【摘要】：随着我国的经济水平的不断提高，城市的交通也在快速发展。当前我国各个大中型城市的机动车保有量在急剧的增加，城市的道路载荷越来越超出设计规划时的能力，给城市带来了严重的交通阻塞和交通事故。因此对于机动车驾驶员而言，就需要一种车载导航装置，能够帮助驾驶员快速、安全、便利地指引到目的地。而基于GIS的智能导航技术就是解决该问题的有效途径。本文首先分析了地理信息系统（GIS）的架构和工作原理，包括GIS定义、GIS组成、GIS分类、GIS的主要功能等内容。然后对智能导航系统的自动化和智能化发展进行研究，通过对GPS导航技术、地图匹配技术以及交通流等各相关技术的研究，从技术实现的角度探索符合我国交通特性的智能导航系统。智能导航系统是通过GIS查询道路的通行状况，提供道路通行方案，，为提高道路的通行能力，舒缓交通阻力，提高道路通行的安全系数。本文主要针对智能导航系统的一些关键技术进行深入剖析，对影响系统实现的关键算法和技术内容进行重点攻关，并在结合交通流路网特点的基础上，对系统中所涉及到的算法进行优化实现，提高系统的实现稳定性和准确性。概括起来，本论文所完成的工作主要有： 1．对智能导航系统中需要采用的各种技术，如GIS技术、地图匹配技术和交通控制理论等进行简单介绍，是本文系统实现的基础； 2．根据我国道路交通的实际特点构建网络模型，对系统中能够采用的路径优化算法进行改进，提供系统性能； 3．通过对整个基于GIS的智能导航系统的详细设计，对系统中的涉及到的功能模块进行详细介绍，同时给出模块实现的技术方法和途径，保证了系统实现的可操作性。本文所设计和实现的智能导航系统，主要是基于GIS技术以及地图匹配技术所完成，在路径算法上进行优化，行车路线更加合理。系统操作上更加便易，且系统可靠性和稳定性很好。
[Abstract]:With the continuous improvement of economic level in China, urban traffic is also developing rapidly. At present, the number of motor vehicles in large and medium-sized cities in China is increasing rapidly, and the urban road load is more and more beyond the capacity of design and planning, which brings serious traffic congestion and traffic accidents to the cities. Therefore, for vehicle drivers, a vehicle navigation device is needed, which can help drivers to guide to their destination quickly, safely and conveniently. The intelligent navigation technology based on GIS is an effective way to solve this problem. This paper first analyzes the structure and working principle of GIS, including the main functions of GIS classification and GIS. Then, the automation and intelligent development of intelligent navigation system are studied. Through the research of GPS navigation technology, map matching technology, traffic flow and other related technologies, From the point of view of technical realization, this paper explores the intelligent navigation system which accords with the traffic characteristics of our country. The intelligent navigation system is to inquire the traffic condition of the road through GIS, provide the road traffic plan, in order to improve the capacity of the road, ease the traffic resistance, improve the safety factor of the road. In this paper, some key technologies of intelligent navigation system are deeply analyzed, and the key algorithms and technical contents that affect the realization of the system are discussed, and based on the characteristics of traffic flow network, The algorithms involved in the system are optimized and implemented to improve the stability and accuracy of the system. To sum up, the main work accomplished in this paper is as follows: 1. A brief introduction of various technologies needed in the intelligent navigation system, such as GIS technology, map matching technology and traffic control theory, etc. 2. According to the actual characteristics of road traffic in China to build a network model, the system can be used to improve the path optimization algorithm to provide system performance; 3. Through the detailed design of the whole intelligent navigation system based on GIS, the functional modules involved in the system are introduced in detail, and the technical methods and ways to realize the modules are also given. It ensures the maneuverability of the system. The intelligent navigation system designed and implemented in this paper is mainly based on GIS technology and map matching technology. The route algorithm is optimized and the route is more reasonable. The operation of the system is easier, and the reliability and stability of the system are very good.
