摘要随着国内经济的迅猛增长，人民的生活水平显著提高，而一些其他问题也随之而来，私家车的数目的增多导致了交通的拥堵，绿色出行的理念慢慢被人们接受并提倡。使用公共交通工具既缓解了交通的压力，使得出行更为便捷，又减少了对环境的污染。本文讨论了基于PHP+MySQL的公交轨迹回放系统软件的设计与实现，其中重点描述了系统软件的实现，包括系统分析、系统调查、数据流程分析、功能设计、数据库设计等。系统采用Web-GIS技术，通过百度地图和php实现对公交车的GPS位置信息管理。本系统的主要功能模块如下：查询公交车的线路信息、提供车辆换乘导航服务。查询某一辆公交车的实时GPS信息、车辆当前位置、车辆运行轨迹。系统通过浏览器实现公交车轨迹的回放、当前位置显示等功能，方便了百姓乘坐公交车以及工作人员管理公交车。关键词：GPS；轨迹回放；WebGIS。AbstractWiththerapidgrowthofthedomesticeconomyandpeople'slivingstandardsimprovedsignificantly,whilesomeotherproblemhascroppedup,theincreasingnumberofprivatecarshasledtotrafficjams,theconceptofgreentravelslowlybeingacceptedandpromoted.Usingpublictransportbothtoeasethepressureoftraffic,makingtravelmoreconvenient,butalsoreduceenvironmentalpollution.ThispaperdiscussedthedesignandimplementationofPHP+MySQLbustrackplaybacksystem,whichfocusesdescribestheimplementationofsystemsoftware,includingsystemanalysis,systemsurvey,dataflowanalysis,functionaldesign,databasedesign.SystemusesWeb-GISBaiduMapsandphptechnologytorealizethebusGPSlocationinformationmanagement.Themainfunctionalblocksofthesystemareasfollows:Querybuslineinformation,providingtransfervehiclenavigationservices.Checkabusinareal-timeGPSinformation,thecurrentpositionofthevehicle,thevehicletrajectory.Systemthroughthebrowserimplementationsbustrackplayback,thecurrentpositiondisplayfunctiontofacilitatethepeopletotakethebusandthebusstaffmanagement.Keywords:GPS;trackplayback;WebGIS目录引言.......................................................................................................................................1第一章系统分析.................................................................................................................21.1系统需求分析..............................................................................................................21.2用户需求......................................................................................................................21.3系统可行性分析..........................................................................................................3第二章系统开发技术准备.................................................................................................42.1WEB-GIS技术介绍........................................................................................................42.1系统开发所需工具......................................................................................................42.2开发环境的搭建..........................................................................................................4第三章系统设计.................................................................................................................83.1系统总体结构设计.....................................................................................................83.2.数据库设计..................................................................................................................93.2.1数据库的完整性...................................................
