Formulation and Evaluation of Cost Saving for Adaptive Dynamic Weight Station at the Entrance of Expressway

Cost saving algorithm was established based on the way of stage prediction. By analyzing the truck delay influence factors for the entrance of a toll gate, an entrance delay time saving algorithm was determined. Considering TTI algorithm and the actual road traffic situation, the model of maintenance cost saving was obtained. Each saving item was quantified in this paper. It provided theoretical support for adaptable dynamic weight station economically.
