AlsoGrün - All red / instantly green at signalised pedestrian crossings
Abstract
Signalised push-button pedestrian crossings show in the standard case green for the motorized traffic and the red stop light for pedestrians. Therefore, the waiting time for pedestrians for the green light is at least 8 s, and often longer. Consequently pedestrians are frequently tempted to disregard the red light phase, and also vehicle drivers do when they find the zebra crossing empty. As the main goal of the project a push-button pedestrian crossing system was, for the first time in Austria, be converted to the basic position "All-Red/Green-Instant" and evaluated in a field test under real conditions. The main results were that – compared to the original situation – the objectively measured waiting times for pedestrians have been substantially reduced, which was also perceived subjectively. The speeds of vehicles approaching this spot were reduced and levelled out in the course of the day. Furthermore, the percentage of drivers who ignored the speed limits has decreased. A potential drawback is, however, that the number of pedestrians and cyclists as well as drivers who disregard the red lights has increased. As everybody is encountering new and quickly alternating signalling sequences they are not used to, a period of familiarisation has to be reckoned with. Drivers have neither displayed significant enthusiasm for or categorical rejection of this “All-Red/Instant-Green” project while pedestrians have accepted it readily. The experiences with the practical operation of the adapted traffic lights have been generally good, too. Summing up, the evaluation of the pilot project has been very positive. The system with the “All-Red/Instant-Green” signalisation in Graz has been running since its launch in March 2016 unchanged.
