Ctbssp Synthesis 23

TRB Commercial Truck and Bus Safety Synthesis Program (CTBSSP) Synthesis 23: Operator Drug and Alcohol Testing Across Modes explores practices used to deter drug and alcohol use among operators within the U.S. Department of Transportation (DOT) regulated community. The report includes a brief history of the transportation workplace drug and alcohol testing program, the general approach, the reasons for testing, some of the issues that impact the validity of the tests, and an outline of the specific regulations by mode. Some alcohol and drug testing statistics are presented in the report to help provide a sense of the scope of the program and of the prevalence of illegal alcohol and drug use among safety sensitive employees. The report also highlights alternative strategies aimed at helping to deter illegal alcohol and drug use among employees.

"TRB's Commercial Truck and Bus Safety Synthesis Program (CTBSSP) Synthesis 21: Driver Selection Tests and Measurement synthesizes information on the use of tests, measurements, and other assessment methods used by commercial truck and bus companies in the driver selection process. The report also identifies and describes driver selection methods and instruments and their potential usefulness in predicting driver crash risk."--Publisher's description.

"TRB's Hazardous Materials Cooperative Research Program (HMCRP) Report 7: Role of Human Factors in Preventing Cargo Tank Truck Rollovers analyzes the causes of the major driver factors contributing to cargo tank truck rollovers and offers safety, management, and communication practices that can be used to help potentially minimize or eliminate driver errors in cargo tank truck operations. The report focuses on three areas of practice--rollover-specific driver training and safety programs, the use of behavior management techniques, and the use of fitness-for-duty management practices--that could have long-lasting benefits for motor carriers of all sizes across the tank truck industry."--Publisher's description.

Advancement in design and construction to embrace the impact of rapid global urbanization growth in infrastructure development is inevitable. This proceedings volume includes many smart and green solutions for civil infrastructures, incorporating geotechnical and engineering geology aspects. The articles presented in this volume are attempts made by the researchers and practitioners to address many geotechnical challenges, based on the state-of-the-art practices, innovative technologies, new research results and case histories in construction and design towards safer and cost effective infrastructures. This volume covers a wide range of topics with direct relevance to people within the broad field of geomechanics, including consultants, contractors, academics, materials suppliers and the owners and operators of civil infrastructures. Many papers associated with numerical modeling of transport infrastructure, advanced soil and rock testing, field monitoring, tunnelling, expansive soils, geo-center motion, triaxial and dynamic testing, piles etc. are included. The content is based on the contributions to the 6th GeoChina International Conference on Civil & Transportation Infrastructures: From Engineering to Smart & Green Life Cycle Solutions -- Nanchang, China, 2021.

"This report completes and updates the first edition of NCHRP Report 600: Human Factors Guidelines for Road Systems (HFG), which was published previously in three collections. The HFG contains guidelines that provide human factors principles and findings for consideration by, and is a resource document for, highway designers, traffic engineers, and other safety practitioners."--Foreword.

This comprehensive 2nd edition covers the key issues that relate human behavior to traffic safety. In particular it covers the increasing roles that pedestrians and cyclists have in the traffic system; the role of infotainment in driver distraction; and the increasing role of driver assistance systems in changing the driver-vehicle interaction.
