Abstract
With the development of the economy, urban expressways have increased year by year, and their traffic safety issues have been attracted more and more attention. This article takes Nanjing Chengxin Avenue Expressway as an example. Investigating actual traffic flow data, five evaluation indicators such as traffic volume, speed and v/c ratio are selected, and the fuzzy analytic hierarchy process is used to calculate and evaluate the safety of Nanjing Chengxin Avenue Expressway. The study found that it was a relatively safe level and proposed preventive measures to reduce traffic accidents.
