TRB's National Cooperative Highway Research Program (NCHRP) Synthesis Report 322: Safety Management Systems (SMS) provides an overview of current transportation agency practices, recent literature findings, and reviews of two model state SMS initiatives. According to the report, benefits derived from the SMS process are increased coordination, cooperation, and communication among state agencies and improvements to data analysis and collection procedures, as well as collaborative strategic plans.

This study provides information to state DOTs on roadway safety hardware management systems that could help increase their use of state-of-the-art practice techniques. The is report was developed for State DOT personnel, particularly chief engineers and other top management, involved with the planning, funding, and execution of roadway safety hardware management systems.

Transport systems are facing an impossible dilemma: satisfy an increasing demand for mobility of people and goods, while decreasing their fossil-energy requirements and preserving the environment. Additionally, transport has an opportunity to evolve in a changing world, with new services, technologies but also new requirements (fast delivery, reliability, improved accessibility). The subject of traffic is organized into two separate but complementary volumes: Volume 3 on Traffic Management and Volume 4 on Traffic Safety. Traffic Safety, Volume 4 of the Research for Innovative Transports Set, presents a collection of updated papers from the TRA 2014 Conference, highlighting the diversity of research in this field. Theoretical chapters and practical case studies address topics such as road safety management and policies, accident analysis and modeling, vulnerable road users' safety, road infrastructure safety, ITS and railway safety.
