SAFETY COST-EFFECTIVENESS OF INCREMENTAL CHANGES IN CROSS-SECTION DESIGN--INFORMATIONAL GUIDE

This guide presents information for estimating the costs and safety benefits which would be expected due to various improvements on specific sections of rural, two-lane roads. Such improvements covered in this guide include lane widening, shoulder widening, shoulder surfacing, sideslope flattening, and roadside improvements. This guide will be useful to those involved with the design of 3R-type projects, particularly for improvement projects which will be constructed on existing vertical and horizontal alignment and within the existing right-of-way. The accident relationships with roadway geometrics and cost data contained in this guide resulted from research conducted for the Federal Highway Administratioon. FHWA research report FHWA/RD-87/008 entitled "Safety Effects of Cross-Section Design for Two-Lane Roads, Volume I, Final Report" contains the major results and conclusions of the study. FHWA research report number FHWA/RD-87/009 subtitled "Volume II, Appendixes" contains details on the data base and the data analysis.
