TRB's Commercial Truck and Bus Safety Synthesis Program (CTBSSP) Research Results Digest 9: A Status Report describes the progress and status of the Commercial Truck and Bus Safety Synthesis Program (CTBSSP). CTBSSP is a cooperative research program sponsored by the Federal Motor Carrier Safety Administration (FMCSA) and administered by the Transportation Research Board. The program was authorized in late 2001 and began in 2002 in support of the FMCSA's safety research programs.
TRB's National Cooperative Highway Research Program (NCHRP) Report 707: Guidelines on the Use of Auxiliary Through Lanes at Signalized Intersections provides guidelines to help in the justification, design, and analysis of auxiliary through lanes (ATLs) at signalized intersections.
ATLs are lanes for through movements that begin upstream of a signalized intersection and end downstream of the intersection. ATLs are potentially a moderate-cost approach to increase intersection and overall corridor capacity.

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's Transit Cooperative Research Program (TCRP) Synthesis 93: Practices to Protect Bus Operators from Passenger Assault highlights practices and policies implemented by transit agencies to deter and mitigate assaults on bus operators.
TRB's Airport Cooperative Research Program (ACRP) Synthesis 29: Ramp Safety Practices addresses the current state of ground handling practices, focusing on safety measures and training.
Issues addressed in the report include ramp safety operations, staff roles and responsibilities, safety training, audit and inspection programs, safety violation programs, and collaborative safety initiatives, such as foreign object debris programs.
TRB's Transit Cooperative Research Program (TCRP) Report 149: Improving Safety-Related Rules Compliance in the Public Transportation Industry identifies potential best practices for all of the elements of a comprehensive approach to safety-related rules compliance.
The categories of best practices, which correspond to the elements of a safety-related rules compliance program, include screening and selecting employees, training and testing, communication, monitoring rules compliance, responding to noncompliance, and safety management.
The report also outlines the features
TRB's Airport Cooperative Research Program (ACRP) Synthesis 28: Investigating Safety Impacts of Energy Technologies on Airports and Aviation explores physical, visual, and communications systems interference impacts from energy technologies on airports and aviation safety.
The energy technologies that are the focus of this report include the following:
â€¢ solar photovoltaic panels and farms,
â€¢ concentrating solar power plants,
â€¢ wind turbine generators and farms, and
â€¢ traditional power plants.
Nearly everyone experiences fatigue, but some professions--such as aviation, medicine and the military--demand alert, precise, rapid, and well-informed decision making and communication with little margin for error. The potential for fatigue to negatively affect human performance is well established. Concern about this potential in the aviation context extends back decades, with both airlines and pilots agreeing that fatigue is a safety concern. A more recent consideration is whether and how pilot commuting, conducted in a pilot's off-duty time, may affect fatigue during flight duty. [more]
TRB's National Cooperative Highway Research Program (NCHRP) Report 705: Evaluation of Safety Strategies at Signalized Intersections explores crash modification factors (CMFs) for safety strategies at signalized intersections. CMFs are a tool for quickly estimating the impact of safety improvements.
TRB's second Strategic Highway Research Program (SHRP 2) Report S2-L10-RR-1: Feasibility of Using In-Vehicle Video Data to Explore How to Modify Driver Behavior That Causes Nonrecurring Congestion presents findings on the feasibility of using existing in-vehicle data sets, collected in naturalistic driving settings, to make inferences about the relationship between observed driver behavior and nonrecurring congestion.
The report, a product of the SHRP 2 Reliability focus area, includes guidance on the protocols and procedures for conducting video data reduction analysis.
