| Abstract |
Reducing vehicular speed is a primary target in pedestrian safety policy. However, its validity in shared, narrow, and crowded environment of typical neighborhood streets has been barely questioned. This study empirically investigates the speed and related factors, based on monitoring data from 45 cases of Pedestrian Priority Streets pilot projects in Seoul. Overall, the average speed was 18km/h, and 80% stayed between 10-25km/h. Despite intentions, speed after the treatment increased, by average and in more cases. Pedestrian flow and other exposure variables were decisive as speed restraints. Speed changes depended mainly on the previous speed. Cases with previous high speed and few restraints deserve viable measures against the speed issues. Meanwhile, acceleration might be a sign of improvement where low speed is associated with excessive delay, congestion and conflicts. This ambiguity suggests that goals and priorities, design and evaluation of neighborhood streets should be articulated to embrace the environmental and behavioral diversity. |
