Micro-level Investigation of the Effects for Pedestrian-Pedestrian and Pedestrian-Vehicle Interactions and Other Factors on Crossing Speed in Pedestrian Crossings

Abstract

Pedestrian crossings play an important role in the safety and mobility performance of signalized intersections. In improving pedestrian crossings, it is important to calculate the crossing speed. In practice, different average pedestrian crossing speeds can be effective in different pedestrian crossings. The differences in the design speeds also support the need to calculate local pedestrian crossing speeds in order to provide the most suitable designs. In the study, factors affecting pedestrian speeds at the selected signalized pedestrian crossing in Mersin city center were examined at a micro level. As a result of statistical analyses for the 1868 pedestrian crossing, the effects of gender, age, group behaviour, load condition in hand, telephone preoccupation, traffic and pedestrian volume on pedestrian crossing speeds were examined. The average crossing speed was calculated at 1.14 m/s. Individual situations affecting speed were found to be factors such as age, group behavior and having loads in hand. In addition, the actual subject studied was the signal effect, direction factor, and pedestrian-vehicle interaction factors studied by statistical methods and cumulative percentage pass rate graphs. Contrary to what is expected, pedestrians who exhibit angle crossing behavior with unregulated pedestrians have a lower crossing speed than canonical and normal passing pedestrians. In pedestrian crossing design, considering vehicle-pedestrian interaction while collecting data; It has been revealed by calculations that the cross and illegal crossings of pedestrians should be reduced and the width of the railings should be adjusted correctly. In addition, it is important to accurately determine the width of the crosswalk, which has an impact on the speed of the pedestrian.
