Pedestrian Mid-Block Crossing Difficulty

摘要

This report documents a research project that developed a model of mid-blockcrossing difficulty as perceived by pedestrians. Four aspects of the research are reported: research design issues, selection of potential determinants, data collection, and statistical analysis. This model was done through a statistical calibration and validation process involving collecting actual site characteristics and stated levels of crossing difficulty by a sample of persons at a sample of sites from Hillsborough and Pinellas Counties in Florida. For traffic operations applications, this model may be used as a screening tool to determine whether pedestrian midblock crossing facilities, such as crosswalks or pedestrian signals, may be needed at particular locations. For planning purposes, this model has a number of applications: (1) it can be used as a measure of effectiveness for determining pedestrian level of service for mid-block crossing; (2) it could potentially be combined with those for pedestrian level of service for walking along a roadway segment and for crossing at intersections to determine the overall pedestrian level of service for an entire roadway segment; and (3) This overall level of service at the segment-level could then be used as a direct input into transit level of service methodologies that take into account pedestrian street-crossing difficulty.
