Abstract: In view of the complex urban road environment and the larger exposed population in the hazardous materials(Hazmat) accidents area,a comprehensive risk assessment model based on possibility and consequences of accidents was built to objectively evaluate the risk of transportation of hazmat on urban roads.Firstly,the risk factors were obtained by exploring Hazmat characteristics and the transportation process.Secondly,ordered Logit model was used to build a risk assessment model of accident probability,and a risk assessment model of accident consequence was built based on material safety diamonds,thus the risk level of each section in the transportation route could be calculated by using the aforementioned models.Finally,the risk of transportation route for Hazmat could be obtained based on the distance weighting method.The results show that the results of risk assessment can provide a sound basis for taking effective prevention and control measures,reducing the probability and losses of accidents occurred on urban roads.

Key words: Hazmat transportation, urban roads, risk assessment, accident probability model, accident consequences evaluation model, ordered Logit model, material safety diamonds, distance weighting method
