The Design And Implementation Of The Urban Traffic Query System Based On Geographic Information

In recent years, Because of the number of vehicles is increasing, Bus lineadjustment frequently, Street maintenance frequently, City Road load increasing, thetraffic congestion, blocking roads, travel inconvenience has become the negativefactors which is not conducive to social development, city traffic is in urgent need toimprove the hardware facilities at the same time, establish and improve the supportingsoftware aided system, city traffic query system to solve the traffic problems. Thesystem provides information through the Internet, telephone, also through the portablecomputer, palmtop computer check. Person, car, road organically, can effectivelyalleviate traffic congestion, improve efficiency, provide convenience for the trip.The paper detailed demand analysis, identified the main functions of the systeminclude a map search, query, car navigation, the surrounding query, map basic operationmodule. Then, given the system outline design and detailed design, finally, based on B/S architecture, Lucene tools and.Net technology as one of the city traffic query system,this system adopts MVC design patterns, using Oracle database, and, according to themap search, query, driving directions and the surrounding query function module,choose an applicable and efficient algorithm of the shortest path.This paper completed the traffic query system which arrives to the standard ofdesign objectives after being tested,The system can provide users with urban real-timetraffic information and the convenience of information. For example, system providesmorning and evening peak road, single-and double-limit line sections, sections of theclosed, bus routes and other information, guides the user’s driving or riding route,reducing the vehicle in the road time so as to realize the improvement of traffic andavoid the traffic congestion of the objective to improve road traffic system.
