The objective of this project is to develop a technical basis by which practitioners apply Safe System methodology to inform planning and design decisions to minimize roadway departure fatalities and serious injuries.
The objective of this project is to develop an acceptance plan that can be used as guidance by the states when they are developing their standard specifications, standard details, and special provisions for High Tension Cable Barrier (HTCB) projects. This document will help to ensure conformance with the state-of-practice for HTCB systems and improve uniformity of HTCB installations among states. This is continuation of NCHRP 22-40 which was an update to AASHTO M 180 "Standard Specification for Corrugated Sheet Steel Beams for Highway Guardrail".
The objectives of this project are 1) to determine the effects of curbs on the crashworthiness of selected roadside safety hardware at various speeds, geometries, and offsets from the curb, 2) to develop guidelines for the use of roadside safety hardware in combination with curb, 3) to prepare the guidelines for incorporation into a future update of the AASHTO Roadside Design Guide, and 4) provide recommendations for any additional crash testing requirements that should be made to MASH on roadside safety hardware installed in combination with curb.
The objective of this project is to develop a course to help participants 1) perform evaluations using MASH guidelines and crash test data and 2) interpret crash test results to determine whether or not the hardware meets MASH performance criteria.
The objective of this project is to develop ISPE guidelines to define and recommend nationally acceptable field performance criteria for roadside safety hardware based on the evaluation measures within NCHRP Research Report 1010.
