Design And Implementation Of Road Evacuation Mechanism Based On Congestion Prediction Algorithm

With the acceleration of urban development and the enrichment of people's livegradually,automobiles have become necessities of our lives,so that transportation problems that accompany them have gradually become pain points in our lives.Traditional congestion measurement algorithms lack of accuracy when measuring traffic congestion condition,and cannot deal with traffic problem overall.Therefore,this paper proposes a congestion assessment algorithm using multi influence factors and future prediction mechanism which measure road reasonably.In this paper,the congestion algorithm of RENS can combine road's multiple influence factors to evaluate the road's congestion condition,so as to measure the road congestion condition on the whole level.Algorithm is based on the WSNs,which provide many sensor nodes to monitor and transmit traffic message in time.This paper takes more aspects for traffic into consideration,including congestion situation,danger condition and sudden road peak flow,and turns them into weights,which help to measure congestion intensity.According to congestion intensity,congestion field is established to navigate for the vehicles.Furthermore,we propose future prediction mechanism for vehicles.Traffic condition always change fast,so the real-time data can't adapt well to the traffic characteristics in the road navigation.After studying other researches,we have added a time prediction mechanism so that the overall navigation mechanism is not based only on the real-time traffic status.In addition,this prediction mechanism also has a good effect on the peak flow own to the prediction accuracy.Finally,we do simulation with Matlab to evaluate the performance of the prediction mechanism,and results show that the performance of prediction mechanism is better than greedy algorithm.Moreover,a route will be recommended after a comprehensive evaluation about the distance,time,congestion and traffic lights number.In a word,the prediction mechanism for traffic can not only ensure the effectiveness of the navigation,but also protect drivers from the sudden peak flow,which brings convenience and comfortableness to drivers.
