Study On Traffic Guidance Technology Of Mountainous Tourist Road

Because of the terrain restriction,the tourist highway in mountainous cities is congenitally insufficient.The increasing number of private vehicles in tourist areas aggravates the traffic congestion of hot tourist highways.Taking Wulong Xiannu Mountain in Chongqing as an example,this paper studies the traffic guidance technology.Through traffic volume forecast and traffic state discrimination,the guidance scheme and emergency plan of Wulong Xiannu Mountain are formed,which provides the basis for the smooth guarantee of Wulong Xiannu Mountain road network and promotes the traffic development and tourism development of Wulong Xiannu Mountain.The research is carried out from the following aspects:Firstly,this paper analyzes the current traffic data acquisition technology,combines with the current situation of traffic data acquisition of tourist highway,determines the traffic data processing method,and carries out traffic data fusion.Based on the large traffic data environment,and carries out the short-term traffic volume prediction research with the classification algorithm K-NN proximity algorithm,taking the Xiannu Mountain tourist highway as the example.A case study on short-term traffic volume forecasting is carried out.Secondly,the FCM algorithm is used to discriminate the traffic state.The results show that different combinations of traffic parameters have a great influence on the traffic state discriminant results.It is found that under certain sample size,traffic flow and speed are taken as the evaluation parameters of traffic state.Then,based on the optimized FCM traffic state discriminant model,a single lane traffic state discriminant method based on the principle of maximum membership degree is proposed,and a single lane traffic state fusion model is given,and the feasibility of this method is verified.In addition,in order to obtain the section unit traffic state,a joint discrimination method of intersection traffic state fusion and average travel speed is proposed,and the range of average travel speed under different traffic conditions is given,and the feasibility of this method is demonstrated.Finally,combined with the status quo and planning of the back road network,taking the real-time state of road traffic as the basis for decision-making,and integrated with video on-site monitoring,the paper studies the current traffic guidance strategy and corresponding emergency plans of Xiannu Mountain tourist highway area,in order to provide a basis for the protection of Xiannu Mountain tourist area road network traffic accessibility and smoothness.In this study,the theoretical method and on-the-spot measurement method are used to study the traffic guidance technology of tourist highway in mountainous cities.Combining with the information collection and release technology of intelligent transportation,the corresponding guidance strategies and schemes are put forward in combination with the actual situation,which can be used for the planning of tourist highway network,the construction of intelligent transportation and the corresponding traffic in the following mountainous cities.A reference is provided for the study of induction methods.
