Research on the Road Bearing Capacity Based on Real-Time Data

Abstract

To represent the road network operation effectively, a model for road bearing capacity (the product of speed and flow) is proposed, and the reliability of road network is also evaluated based on the mass traffic data with the aid of reliability engineering. Specifically, the bearing capacity is proposed after analyzing the operation characteristics of road network with existing mass data. Then, with the help of statistical knowledge and distribution fitting of the detect data, it is found that the values of the bearing capacity of road network are normally distributed. Moreover, the reliability of the bearing capacity is proposed based on reliability engineering, in order to obtain the framework of the bearing capacity changing with space-time. The results show that the proposed model of bearing capacity and its framework changing with space-time can simulate road network operation effectively.
