摘      要：We analyze the effect of using a vehicular ad-hoc network(VANET) on accident *** shown in our analysis,a higher frequency of safety packets can prevent accidents,even for high speed vehicles and dense *** overcome connectivity problems in blind crossing situations,a genetic algorithm(GA) based method is presented for VANET infrastructure *** proposed approach tries to remove coverage sight holes in low sight distance cases in a traveling path in the *** such places,drivers might not have enough sight for proper action and also environmental obstacles prevent direct communication between ***,curved roads affect *** results show that the density of vehicles is increased right before a curve and is decreased after ***,in this kind of road,a high frequency of packet generation may not act well in accident *** method proposed in this paper tries to cover such places considering the lowest safety distances according to traffic *** this,the road must be covered directly by ***,the problem is to find the best number and also positions of road side *** GA,the algorithm minimizes the summation of total uncovered and overlapped points in the roads which are covered by more than one *** on a real road map confirmed the capabilities of the proposed approach.
