Safety Aspects of Curb Parking. Executive Summary

摘要

Parking and accident data were collected on over 170 miles of streets in 10 cities in the U.S. Over 4,800 accidents were tabulated and analyzed. Intersection and midblock accident comparisons were made for selected cities, and midblock accident rates were computed for various stratifications including street functional classification, land use, parking utilization and parking type. No relationship was found between accident rate and street width or parking angle. Accident rate was found to vary however with land use and parking utilization. Installation of parking prohibitions was estimated to reduce midblock accident rates from 19% to 75%, which is equivalent to total on-street accident rate reductions of 8% to 30%. Field operational studies were made relative to the effects of different types of parking on speeds, vehicle placement, delays and conflicts.
