Effectiveness of Interventions at Midblock Crossings for Improving Senior and Other Pedestrian Safety

This project will evaluate the effectiveness of designed interventions on pedestrian crash experience at midblock crossings, focusing on seniors, children and other pedestrians. From the large crash database, the project will study crashes involving pedestrians in situations with and without the interventions, and merge this data against a database containing the road and roadside characteristics. The project will fit a suitable regression and identify important covariates. Conflicts between pedestrians and vehicles subject to the interventions will be observed using a variation of the Swedish Traffic Conflicts Technique, and classified by estimated age of the pedestrian and the severity of the conflict. Observations will be made at locations specifically targeted for having characteristics found to be associated with senior pedestrian crash severity relative to non-seniors. At these observation locations, speed will also be observed. The project proposes a statistical test of association between conflict severity and crash severity based on data obtained through the field observation and sampled from the crash database. It will be useful to compare the associations under interventions to that with no intervention. The project also proposes, in the presence of interventions, a hierarchical regression of crash severity on road and road characteristics as well as conflicts severity, where conflict severity is itself modeled as a function of relevant predictors. The project will acquire data from the Connecticut Crash Data Repository now being developed at the University and share results with the users of the Repository through a Living Laboratory arrangement.
