Safety Comparison of Different Transport Mode: A Fuzzy Theory Based Approach

There are four major types of macro-evaluation on traffic safety traditionally adopted in China and overseas. However, as the number of influential factors of traffic safety increases, these evaluation methods are becoming less capable in practice. The introduction of Fuzzy Theory provides a new approach to this problem. This paper based on the traffic accident data of Shanghai and Suzhou has established a macro-evaluation model for assessing the safety performance of mixed transport modes, which include cars, motorcycles, gas motorcycles (LPG), electric bicycles and traditional bicycles. The model indicates that the safety performances of LPG, electric bicycles and traditional bicycles are much higher than that of cars and motorcycles. Electric bicycles and traditional bicycles have similar safety performances in the two cities. These findings set up a reference for the establisher of urban transport policies.
