Abstract
The purpose of the optimization of holiday traffic emergency traffic organization is to solve the problem of serious traffic jams in holiday scenic spots. Based on the prediction of traffic volume and traffic mode division in the future years of the scenic spot, the traffic accident route is analyzed to provide theoretical support for the emergency traffic organization and planning of the scenic spot. This article takes the Shijiazhuang Jinta Bay scenic area as the research object, based on the traffic volume of the Jinta Bay tourist scenic area from 2009 to 2016, analyzes the traffic environment of the scenic area, predicts the traffic demand, and builds a one-way traffic organization double-layer optimization model. The simulated annealing algorithm is used to solve the model, an emergency transportation organization optimization plan is formulated, and the feasibility of the plan is verified through VISSIM simulation. The results of the study show that the one-way traffic organization method reduces the average vehicle delay by 32.2% and the average queue length by 14.5%. The one-way traffic organization based on branch diversion can more effectively solve the main road jamming and congestion caused by traffic accidents, prevent the occurrence of secondary accidents, and reduce the economic losses of scenic area managers. At the same time, the purpose of ensuring the tourist quality of tourists and the economic interests of scenic spot management departments is ensured.
Highlights
With the rapid development of social economy, the number of tourists in China is increasing and tourists are pursuing a higher travel experience
The duration of the accident is 200 s, and the proportion of cars and buses is 1 : 9. Traffic accident congestion traffic flow operation diagram is shown in. It can be seen from the simulation results that when the branch area is evacuated in the one-way traffic organization mode, the node conflicts due to traffic accident congestion are reduced, and the conflicts with the opposite vehicles are eliminated
The one-way traffic organization based on branch diversion can more effectively solve the main road jamming and congestion caused by traffic accidents, prevent the occurrence of secondary accidents, and reduce the economic losses of scenic area managers
Summary
With the rapid development of social economy, the number of tourists in China is increasing and tourists are pursuing a higher travel experience. On the basis of urban road network and expressway network traffic accident emergency traffic organization plan, combined with the characteristics of the scenic spot network, so as to build a holiday scenic spot network traffic accident congestion evacuation method [14], this article takes the Shijiazhuang Jinta Bay tourist scenic spot as an example, analyzes the traffic profile of the scenic spot, and predicts the traffic demand of the scenic spot during the peak holiday season. The prediction model is shown as follows in Formula (1)
