Guidelines for Cost-Effective Safety Treatments of Roadside Ditches
Run-off-road traffic crashes account for almost one-third of the deaths and serious
injuries each year on U.S. highways.
The TRB National Cooperative Highway Research Program's
NCHRP Web-Only Document 296: Guidelines for Cost-Effective Safety Treatments of Roadside Ditches
provides new proposed design guidance for the configuration of ditches
adjacent to the roadway.
A supplemental
PowerPoint Summary is available.
