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.

TRB's National Cooperative Highway Research Program (NCHRP) has issued a request for proposals to prepare a proposed Human Factors Guidelines for Road Systems, Fourth Edition (HFG4), which can be used to by state DOTs and other transportation agencies to integrate HF principles into design and operations across roadway systems for all road users. For this research, road users may include, but not be limited to, drivers, pedestrians, bicyclists, motorcyclists, and electric scooter users. This publication will supplement the AASHTO Highway Safety Manual and provide further updates to NCHRP Report 600: Human Factors Guidelines for Road Systems, Second Edition. Proposals are due November 24, 2020 at 5:00 PM Eastern.

TRB's National Cooperative Highway Research Program (NCHRP) has reissued a request for proposals to (1) merge AASHTO Policy on the Accommodation of Utilities within Freeway Right-of-Way and AASHTO Guide for Accommodating Utilities within Highway Right-of-Way, targeting redundancies and necessary revisions and (2) update material within these two documents, where needed, with emphasis on material that has changed or developed following release of the previous edition. Proposals are due December 10, 2020 by 5:00 PM Eastern.
