Abstract


Vehicle-pedestrian collisions may result in serious injuries or fatalities. In order to reduce the number of collisions physical and operational measures are implemented. At signalized intersections, pedestrian and vehicle flows are allowed to cross the common spatial zone at different times. In order to completely separate these two flows overpasses are built. In either case, a considerable number of pedestrians take the risk of crossing illegally (violating the red light rule or crossing at street level). Previously, two signalized intersections and two overpass locations in Izmir, Turkey were analysed regarding the pedestrians’ crossing speed and safety margins. In this study, the data collected from these locations are compared. The observed areas have similar characteristics, such as the number of lanes, the posted speed limit. The overpasses do not serve an escalator or an elevator. The roads where the overpasses are located are divided by a median without any barrier or fence on it, thus providing an alternative crossing for pedestrians who do not prefer climbing the stairs. The signalized intersections are four-legged and offer similar cycle durations. A total of 1692 pedestrians at signalized intersections and a total of 836 pedestrians at overpass locations are observed. The attitude of pedestrians towards these two types of countermeasures will provide an insight to pedestrian risk perception.
