Development of Safety Performance Based Guidelines for the Roadside Design Guide

项目名称：	Development of Safety Performance Based Guidelines for the Roadside Design Guide
摘要：	The AASHTO Technical Committee on Roadside Safety�s (TCRS) mission, as stated in their strategic plan, is to develop, implement, and maintain guidance which will reduce fatal and incapacitating-injury roadway departure crashes. The TCRS maintains the Roadside Design Guide (RDG) which is the primary source of this guidance. There is increasing interest in the highway design community to incorporate methods, based to a greater degree on risk and performance, into guidance and procedures. Consequently, the strategic plan identified a need to (1) review the guidance in the current RDG, (2) identify gaps and areas where updated guidance is needed, and (3) explicitly express this guidance in terms of safety performance. The objectives of this research are to (1) identify and prioritize gaps and needs related to guidance in the AASHTO Roadside Design Guide and (2) develop safety performance-based guidance to address high-priority needs that support quantitative design decisions, and that promote consistency in interpretation and implementation.
