Title: Pavement Edges
Accession Number: 01131603
Record Type: Component
Availability: Find a library where document is available Abstract: This paper reviews the literature on pavement edge drop-offs and their effect of vehicle loss of control. Such drop-offs can occur at the joining of (a) a paved traveled way and an unpaved shoulder, (b) a paved traveled way and a paved shoulder, (c) a paved shoulder and an unpaved adjacent area, or (d) two traveled lanes. When the difference in elevation reaches certain levels for certain edge shapes, safety can be affected. Over time, changes in speed limits and automobile construction have necessitated more analysis and testing. The latest effort to develop a consensus on the influence of pavement edge drop-offs on loss of control is a comprehensive treatment of the status of state department of transportation guidelines, the documentation of automobile testing and simulation, and statistical relationships between edge sizes and shapes and accident frequency. A definitive set of recommendations for constructing and maintaining safe pavement edge condition has now been produced by William D. Lawson and M. Shabbir Hossain.
