In order to meet the needs of highway intersection traffic safety maintenance, the paper carried out a systematical research on the index system and method of highway intersection traffic safety maintenance evaluation, established a complete highway intersection traffic safety maintenance evaluation system. The index system was based on five aspects, namely, the subgrade and pavement, safety facilities, management facilities, crossing channelization and greening; the evaluation index data collecting method and criterion were put forward, and the consistency of the data collection was testified. Then a highway intersection safety maintenance evaluation model and its parameters were given. Finally, by analyzing the relevance of model calculated values of the test intersection and the subjective score values from the experts, the model efficiency was proved.
