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.

In this fully up-to-date volume, important new developments and applications of discrete element modelling are highlighted and brought together for presentation at the First International UDEC/3DEC Symposium. Papers covered the following key areas: * behaviour of masonry structures (walls, bridges, towers, columns) * stability and deformation of tunnels and caverns in fractured rock masses * geomechanical modelling for mining and waste repositories * rock reinforcement design (anchors, shotcrete, bolts) * mechanical and hydro-mechanical behaviour of dams and foundations * rock slope stability, deformation and failure mechanisms * modelling of fundamental rock mechanical problems * modelling of geological processes * constitutive laws for fractured rock masses and masonry structures * dynamic behaviour of discrete structures. Numerical Modelling of Discrete Materials in Geotechnical Engineering, Civil Engineering, and Earth Sciences provides an ultra-modern, in-depth analysis of discrete element modelling in a range of different fields, thus proving valuable reading for civil, mining, and geotechnical engineers, as well as other interested professionals.

The tool kit will vary among jurisdictions depending on basic legal constraints, community attitudes, road system and traffic characteristics, and resources. The Transportation Research Board (TRB) undertook a study to identify the sources of safety improvements in other countries. Researchers do not have a complete understanding of the underlying causes of long-term trends in crashes and fatalities. Differences among countries are in part attributable to factors other than government safety policies. To identify keys to success, the TRB study committee examined specific safety programs for which quantitative evaluations are available and relied on the observations of safety professionals with international experience. The committee's conclusions identify differences between U.S. and international practices that can account for some differences in outcomes. The committee recommendations, which are addressed to elected officials and to government safety administrators, identify actions needed in the United States to emulate the successes that other countries have achieved. The recommendations do not comprehensively address all aspects of traffic safety programs but rather address areas of practice that are highlighted by the international comparisons and for which credible evidence of effectiveness is available."--Pub. desc.

This summary report describes a May 1998 transportation technology scanning tour of four European countries. The tour was co-sponsored by the Federal Highway Administration (FHWA), the American Association of State Highway and Transportation Officials (AASHTO), and the Transportation Research Board (TRB). The tour team consisted of 10 traffic engineers who visited England, France, Germany, and Sweden to observe traffic control devices and methodology and to determine if any European practices should and could be recommended for use in the United States.
