摘要：Drivers' phone use during the red traffic signal and queue discharge activity were investigated at five signalized intersections in Hangzhou, China, with the aims to explore factors influencing phone use behavior while drivers are waiting for a red traffic signal and the impact on the queue discharge. Observations were conducted by recording videos at each intersection during different times of the day and on different days of the week. Of the 2596 drivers observed while waiting at red traffic signals, 36.7% used their phone for some purpose and 20.8% used it until-green. It was found that phone use was not even restricted to within the red-phase of the traffic signal. About 7% continued the use of their phone beyond the redphase while moving off. Logistic regression analyses with phone use as the dependent variable showed that red countdown timer, waiting time, the fact whether the driver was on its own or with a passenger, and the type of vehicle were significant covariates. Start-up delays for queues, with queue leaders whether using their phone or not, were compared using t-test of difference between means. The driving performance, with reference to vehicle headway, was also analyzed against driver phone use. Results reveal that while phone use that was ceased before the change to green has an insignificant effect on the start-up delay, until-green phone use, especially phone use that was continued after-red while moving off, significantly affected the start-up delay and driving performance negatively.
