The AASHTO Highway Safety Manual (HSM) has become a key safety management and evaluation resource for state and local roadway agencies; metropolitan planning organizations; and the safety, design, and traffic engineering professional community. The HSM was developed largely through NCHRP research and the first edition was published in 2010. TRB’s National Cooperative Highway Research Program (NCHRP) has issued a request for proposals to complete the work begun in NCHRP Project 17-71 to develop and prepare a proposed HSM2 in a format suitable for adoption as an AASHTO publication. Proposals are due October 29, 2020 at 5:00 PM Eastern.
