Abstract: Providing flexible and convenient services, taxi becomes one of the most important modes of passenger transport in many major cities of China. However, the increasingly popular taxis have brought several problems to urban traffic. This study explores the characteristics and safety of the following behaviors of taxis on urban road. It is observed that taxis run with smaller following spaces than the ones between public vehicles of other types. Furthermore, the safety of following behaviors of taxis is examined in a quantificational manner with the proposed models. In terms of the numerical examples, the risk-taking following behavior increases the possibility of crashes. The variable of following space can be selected as a predictor of accidents.

Key words: urban traffic, taxi, driving behavior, car following theory, safety analysis
