Employees of state departments of transportation (DOTs) face numerous and dynamic hazards while executing their job duties, including work near moving equipment, work near the traveling public, and work during and responding to natural hazard events. In response, DOTs deploy a wide variety of occupational safety training to provide their employees with the knowledge, skills, and abilities to execute their job duties safely. That wide variety includes various topics, various cycles for updating, various modes of delivery, and various metrics for deployment, among other related issues.

NCHRP Synthesis 665: Occupational Safety Training and Knowledge Sharing for State DOT Employees, produced by TRB’s National Cooperative Highway Research Program, examines how state departments of transportation develop, deliver, evaluate, and update occupational safety training programs. It documents agency practices related to training delivery methods, required training by job function and supervisory level, agencywide versus district-specific programs, and the use of safety data and performance metrics to guide training decisions. The synthesis also reviews approaches for onboarding new employees, measuring training effectiveness, gathering employee feedback, developing specialized training, and involving experienced staff in the creation of in-house training materials. In addition, it examines knowledge transfer planning and the extent to which safety training is provided by in-house staff, consultants, or third-party training providers.

Departments of transportation (DOTs) manage extensive bridge inventories while facing increasing pressure from aging infrastructure, extreme weather events, and evolving federal requirements for risk-informed asset management. The Federal Highway Administration (FHWA) requires DOTs to develop and maintain Transportation Asset Management Plans (TAMPs) that address risk management for National Highway System (NHS) pavements and bridges. Although federal guidance emphasizes incorporating risk into asset management planning, practices for identifying, prioritizing, and integrating bridge-related risks vary widely among DOTs. These differences reflect variations in geographic hazards, network characteristics, funding constraints, institutional capacity, and data availability, making it difficult to standardize approaches for quantifying and incorporating risk into decision-making.

NCHRP Synthesis 667: Identifying Risks and Incorporating Them into Bridge Asset Management Planning, produced by TRB's National Cooperative Highway Research Program, documents current DOT practices for identifying, evaluating, and incorporating risk into bridge asset management planning and bridge management plans. The report examines the types of risks considered, the organizational and decision-making structures used to address them, the prioritization approaches employed, and the integration of risk-based priorities into bridge and transportation asset management planning. It also reviews practices for monitoring and recalibrating risk-informed decisions and considers how incorporating risk influences funding and resource allocation.
