The Analysis of Toilet Use Efficiency in Expressway Service Area Based on Anylogic

As the facility with the highest utilization rate in the expressway service area, the toilet has the greatest influence on the crowd gathering degree in the expressway service area. In order to study the scale and location of toilets in the Meicun service area, this paper conducts a field survey on the service area of Meicun by means of video recording and crowd tracking questionnaire survey. Through the investigation, the key data such as the probability of customers using toilet and toilet turnover rate were obtained. Based on this, the flow model of the crowd in the high-speed service area is established by using the simulation software of Anylogic. In the simulation, the scale and location of the toilet facilities in the high-speed service area are analyzed and evaluated according to the number of people using the toilet at the same time. The results show the influence of different toilet layout on the efficiency of toilet use and the degree of crowd gathering, and prove that double toilets are more efficient than single toilets, disperse the flow of people, reduce the degree of crowd gathering and avoid crowd crowding.
