Abstract

A design consistency method will be incorporated into the Interactive Highway Safety Design Model (IHSDM). The IHSDM is being developed by the Federal Highway Administration (FHWA) as a suite of evaluation tools for assessing the safety impacts of geometric design decisions. The IHSDM focuses on the safety effects of design alternatives. The information in this technical summary pertains to new data concerning the Design Consistency Module, one of seven modules being developed as part of the IHSDM. This technical summary announces the completion of an FHWA study that is fully documented in three separate reports: "Evaluation of Design Consistency Methods for Two-Lane Rural Highways, Executive Summary" (FHWA-RD-99-173); "Speed Prediction for Two-Lane Rural Highways, Final Report" (FHWA-RD-99-171); and "Alternative Design Consistency Rating Methods for Two-Lane Rural Highways, Final Report" (FHWA-RD-99-172).
