Can pedestrians’ crossing countdown signal timers promote green and safe mobility?

The study presents the evaluation of the efficiency of crossing countdown timers (PCCST) for pedestrians at signalized pedestrian crossings. It is based on observations of the behaviour of pedestrians and motorists at an intersection, located in a major city in Greece. A series of surveys and pedestrian interviews were conducted to evaluate the behaviour of pedestrians and motorists. Data statistical analysis indicated that the countdown signals are able to provide pedestrians with valuable information that enhances the safety level as far as crossing of the intersection is concerned. The pedestrian interviews revealed that most of them properly interpreted the meaning of the “green man” signal and the countdown clock. Finally, it is considered desirable by the pedestrians to install pedestrian countdown signals in other signalized pedestrian crossings as well.
