Because the current research on traffic level has not yet been achieved classification, it cannot timely and effectively provide the basis for the public transportation and safety management of the traffic control department. Introduce traffic safety index based on toll data to evaluate freeway traffic levels. Firstly, combined with the relevant indicators of traffic engineering, put forward the concept of freeway traffic safety index; secondly, calculate the traffic safety index by analyzing real-time toll data; finally, in order to improve the accuracy of evaluation, have an optimization of traffic safety index definition. Application on the Beijing-Hong Kong-Macao freeway shows that traffic safety index can be combined with monitoring data to evaluate the condition of road sections and the road network, and its historical data can be used to predict the road traffic conditions, and provide effective guidance for freeway traffic safety operation.
