Ctbssp Synthesis 20

TRB's Commercial Truck and Bus Safety Synthesis Program (CTBSSP) Synthesis 20: Potential Safety Benefits of Motor Carrier Operational Efficiencies addresses risk avoidance strategies and highlights their use and perceived safety effects. The report is designed to assist motor carriers in deploying their vehicles in ways that may minimize crash risk.

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 13: Effectiveness of Commercial Motor Vehicle Driver Training Curricula and Delivery Methods explores the state of commercial motor vehicle (CMV) operator training in the trucking and motorcoach industries. The report examines the experiences of training programs that are using some combination of simulators and computer-based instruction and identifies measures of training effectiveness being used in the CMV community.

TRB's Commercial Truck and Bus Safety Synthesis Program (CTBSSP) Synthesis 22: Safety Management in Small Motor Carriers explores small motor carriers' strengths and weaknesses in safety management, and identifies potentially effective safety practices.

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.
