【摘要】：隨著我國的經(jīng)濟(jì)水平的不斷提高，城市的交通也在快速發(fā)展。當(dāng)前我國各個(gè)大中型城市的機(jī)動(dòng)車保有量在急劇的增加，城市的道路載荷越來越超出設(shè)計(jì)規(guī)劃時(shí)的能力，給城市帶來了嚴(yán)重的交通阻塞和交通事故。因此對(duì)于機(jī)動(dòng)車駕駛員而言，就需要一種車載導(dǎo)航裝置，能夠幫助駕駛員快速、安全、便利地指引到目的地。而基于GIS的智能導(dǎo)航技術(shù)就是解決該問題的有效途徑。 本文首先分析了地理信息系統(tǒng)（GIS）的架構(gòu)和工作原理，包括GIS定義、GIS組成、GIS分類、GIS的主要功能等內(nèi)容。然后對(duì)智能導(dǎo)航系統(tǒng)的自動(dòng)化和智能化發(fā)展進(jìn)行研究，通過對(duì)GPS導(dǎo)航技術(shù)、地圖匹配技術(shù)以及交通流等各相關(guān)技術(shù)的研究，從技術(shù)實(shí)現(xiàn)的角度探索符合我國交通特性的智能導(dǎo)航系統(tǒng)。智能導(dǎo)航系統(tǒng)是通過GIS查詢道路的通行狀況，提供道路通行方案，，為提高道路的通行能力，舒緩交通阻力，提高道路通行的安全系數(shù)。 本文主要針對(duì)智能導(dǎo)航系統(tǒng)的一些關(guān)鍵技術(shù)進(jìn)行深入剖析，對(duì)影響系統(tǒng)實(shí)現(xiàn)的關(guān)鍵算法和技術(shù)內(nèi)容進(jìn)行重點(diǎn)攻關(guān)，并在結(jié)合交通流路網(wǎng)特點(diǎn)的基礎(chǔ)上，對(duì)系統(tǒng)中所涉及到的算法進(jìn)行優(yōu)化實(shí)現(xiàn)，提高系統(tǒng)的實(shí)現(xiàn)穩(wěn)定性和準(zhǔn)確性。概括起來，本論文所完成的工作主要有： 1．對(duì)智能導(dǎo)航系統(tǒng)中需要采用的各種技術(shù)，如GIS技術(shù)、地圖匹配技術(shù)和交通控制理論等進(jìn)行簡(jiǎn)單介紹，是本文系統(tǒng)實(shí)現(xiàn)的基礎(chǔ)； 2．根據(jù)我國道路交通的實(shí)際特點(diǎn)構(gòu)建網(wǎng)絡(luò)模型，對(duì)系統(tǒng)中能夠采用的路徑優(yōu)化算法進(jìn)行改進(jìn)，提供系統(tǒng)性能； 3．通過對(duì)整個(gè)基于GIS的智能導(dǎo)航系統(tǒng)的詳細(xì)設(shè)計(jì)，對(duì)系統(tǒng)中的涉及到的功能模塊進(jìn)行詳細(xì)介紹，同時(shí)給出模塊實(shí)現(xiàn)的技術(shù)方法和途徑，保證了系統(tǒng)實(shí)現(xiàn)的可操作性。 本文所設(shè)計(jì)和實(shí)現(xiàn)的智能導(dǎo)航系統(tǒng)，主要是基于GIS技術(shù)以及地圖匹配技術(shù)所完成，在路徑算法上進(jìn)行優(yōu)化，行車路線更加合理。系統(tǒng)操作上更加便易，且系統(tǒng)可靠性和穩(wěn)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.
