Abstract

The flashing green signal indicates that the green signal will end, and its application at signalized intersections is optional. This paper presents the results of the survey conducted among Belgrade drivers. The survey was conducted in order to analyze behavior, perceptions, knowledge, and attitudes towards the flashing green signal. Results showed that drivers mostly support the flashing green implementation. Also, respondents expressed an opinion that the flashing green improves traffic efficiency and safety. A third of drivers decelerate and stop when flashing green starts. In a situation where the vehicle in front of them decelerate when flashing green starts, 13% of drivers will try to change lane and pass an intersection. This result indicates that drivers of following cars can have conflicting decisions. Results showed that half of the respondents underestimate the flashing green duration while a third of them overestimate it.
