A Study On The Data Model And Scheme Of Intelligent Traffic Guidance Based On Crowdsourcing Map

In the modern society where traffic developes increasingly, so many softwares about map navigation have appeared that people almost can not live well without them. In view of all kinds of electronic map navigation softwares, mostly of which merely provide route planning based on geographic location, and they did not take the suddenly situations of infeasible route because of the temporary reason into consideration.It cannot meet the demands of the people sometimes. So this subject presents a scheme of intelligent traffic guidance which adopts mobile crowd sensing (MCS) technology based on crowdsourcing map to fuse of user generated content (UGC), and designs the data model.The intelligent guidance scheme put forward by this subject, not only contains the basic location information of traditional map navigation, but also integrates traffic data that the user generated and floating car data, so it can provide real-time traffic information that is useful to people and meet the needs of dynamic traffic information of people.Firstly,this paper use the algorithm of intelligent weighted average to fuse the traffic data generated by users,and establish the data fusion model of intelligent traffic guidance.This subject discards the false and retains the true from all the data,and then get the dynamic traffic information in real-time with high accuracy. Secondly,this thesis also study the game theory model to establish a return mechanism, which reward or the punish the users by their action result to constraint people, so that they can create more real and effective content.At last,in order to verify whether the intelligent traffic guidance scheme and data model proposed by this topic is feasible and efficient, this paper has designed and realized the verification system of intelligent traffic guidance scheme.And the paper has simulated the data fusion algorithm and model designed by this topic through Matlab.The relevant research of this subject will further promote the deep integration of mobile Internet and intelligent transportation, and it represents a location service mode of wisdom travel which represents an adaption to the social development.And this will effectively promote intelligent and efficient development of city traffic, and enhance the efficiency of public transport services and city public transportation.
