The American Association of State Highway and Transportation Officials (AASHTO) Manual for Assessing Safety Hardware (MASH) is the latest in a series of documents that provides guidance on testing and evaluation of roadside safety features. The implementation of MASH has been a challenging mission for departments of transportations (DOTs). It has cost the nation tens of millions of dollars. The technology trends and the rapid transformation to electric vehicles place the nation at the cusp of a new era for transportation with big challenges, and the bridge community is anticipating the reevaluation of the crash testing criteria for bridge railing to ensure safety with the new fleet composition. This will be a huge cost to state DOTs. A roadmap for DOTs and other transportation agencies needs to be developed to accommodate this transformation in a timely manner and with a more cost effective solution than the transition to MASH. One of the most expensive and time-consuming pieces of the current process is building full scale test sections and performing the actual crash tests. Often, multiple crash tests are required for a particular solution. The objectives of this project are to (1) explore and articulate the impact of future transformations to the vehicle fleet on the bridge railing MASH requirements, and (2) develop a roadmap for the AASHTO Committee on Bridges and Structures to ensure the safety and support this transformation in a cost effective manner.
