Abstract:

MassDOT actively works with FHWA on the Manual for Assessing Safety Hardware (MASH) implementation. It is critical to plan and manage MASH upgrades and integrate the guardrail asset within its asset management plan with a complete guardrail inventory. This study aims at developing and validating new processes using automated methods to identify and extract locations of in-service guardrails and evaluate condition and compliance using pilot-testing road sections. The detailed objectives include: 1) Developing an automated method for determining the presence of guardrails along the roadway and for extracting critical information, including georeferenced starting and ending points, terminal types, curb presence, lateral offset, and elevation; and 2) Developing an automated method for identifying typical conditional changes for guardrails, including face dent, end terminal damage/missing, guardrail support deficiency. The research team has also investigated the feasibility of identifying missing bolts and connection failures using image processing. The deliverables include a georeferenced guardrail inventory for the selected pilot-testing sections, integrating the in-service condition information.
