• Abstract:
  The objective of this project is to evaluate the effectiveness of the DFS in causing motorists to comply with the posted speed in school zones and potentially improve pedestrian safety. Five school zones were selected for installing and evaluating DFS - Raymond Elementary, Webb Elementary, Maury Elementary, Randle Highlands Elementary, and Stanton Elementary. The five study sites were selected using a combination of factors including pedestrian traffic, average daily traffic (ADT), history of pedestrian conflicts, vehicle speeds, citizen complaints, and coverage of several wards. The ADTs ranged from 10,000 to 30,000 vehicles. The experimental design focused on safety and mobility surrogate measures of effectiveness (MOE) as pedestrian crashes are rare events and unlikely to occur during the short period of the study. Safety MOEs included the proportion of pedestrians in conflict with vehicles, the proportion of vehicles in conflict with pedestrians, and the proportion of braking drivers. Mobility MOEs included mean pedestrian delay and mean vehicle speeds. Data was collected before and after the deployment of the DFS to assist in evaluating the MOE. A customer satisfaction survey was also conducted to assess the extent to which the DFS improved the level of satisfaction of the users of that roadway system.
