随着科技的高速发展,人民生活水平的日益提高,人们出行的日益频繁和日益繁重的交通状况之间的矛盾逐渐激烈.因此,准确有效的为人们提供导航服务的要求也应时而生.本项目分析了现有导航系统的现况,结合当前的时代要求,明确研究的主要内容.首先简单的介绍了hadoop云平台的特点和采用此平台的优越性,其次介绍了如何搭建起服务平台,项目重点在于Dijkstra算法的改造,如何将其适合在hadoop上运行,使其并行化；再次在改造算法的过程中还添加了车辆等路况的模拟,分析了车辆模拟行驶,使之更贴近实际情况；最后对本项目进行了简单的分析和总结,并提出了一些改进方案.

With the rapid development of technology,people's living standards rising,people travel more and more frequent and increasingly heavy traffic conditions the contradiction between the increasingly fierce.Therefore,accurate and effective for people to provide navigation service requirements should also be timely.The project analyzes the current status of existing navigation systems,combined with the current requirements of the times,clearly the main content.First,a brief introduction to the features and hadoop cloud platform advantages of using this platform,and secondly describes how to build up service platform,the project focuses on the transformation of Dijkstra's algorithm,how it fit in hadoop run it parallel; Again in the process of the transformation algorithm also add other road vehicle simulation,simulation analysis of vehicle travel,making it closer to the actual situation; Finally,this project was briefly analyzed and summarized,and made some improvements.
With the rapid development of technology,the increase of people's living standard,the contradiction between people travel is increasingly frequent and increasingly heavy traffic gradually fierce.Therefore,accurate and effective navigation service for people's requirementsalso should sometimes hygiene.This project analyzed the status of existing navigation system,combined with the requirements of the times,the main content of the research.We first introduce thecharacteristics of the Hadoop cloud platform and the superiority of this platform,then describes how to build a service platform,the projectfocuses on the improvement of the Dijkstra algorithm,how it can besuitable for running on Hadoop,so that the parallel; again addssimulated vehicle traffic in the process of transformation algorithm in the analysis,the simulated vehicle driving,and make it more close to the actual situation; at the end of this project are briefly analyzed and summarized,and put forward some improvement scheme.
