Locating Control Stations for Mobile Monitoring of Overloaded Trucks on Rural Highways

In china, overloaded trucks are widespread on rural highways, and the current control measures are inefficient. We propose a new overloaded truck control method that finds overloaded trucks with enforcement vehicles. The enforcement vehicles detect the intercepted trucks with mobile weighing equipment and use the overloaded truck control station as a base. Based on the given number of stations and the number of enforcement vehicles, in order to detect more overloaded trucks, we need optimize the spatial distribution of the stations and the routes of the enforcement vehicles. For this reason, this paper first uses the analytic hierarchy process (AHP) to evaluate some initial alternative locations and selects a group of potential locations for the stations. Second, with the aim of maximizing the number of trucks being detected by the enforcement vehicles, we establish a model to optimize the spatial distribution of the stations and the routes of enforcement vehicles. Finally, a calculation is done with the data of the current rural highways in Guiyang city, China.
