Since September 11, 2001, more than 200 security-, emergency management-, and infrastructure protection-related planning and implementation projects have been initiated through programs managed by TRB. This report, updated monthly, provides information on more than $30 million worth of completed and ongoing TRB security-related research. The report includes information on research that is formally coordinated between the Transit Cooperative Research Program (TCRP) and National Cooperative Highway Researc...

A slideshow summary of the Transportation Research Board's pre- and post-September 11, 2001, transportation security and resilience activities is updated monthly.

TRB's National Cooperative Highway Research Program (NCHRP) has released a pre-publication, non-edited version of Research Report 893: Systemic Pedestrian Safety Analysis. This guidebook provides a safety analysis method that can be used to proactively identify sites for potential safety improvements based on specific risk factors for pedestrians. A systemic approach, as opposed to a “hot-spot” approach, enables transportation agencies to identify, prioritize, and select appropriate countermeasures for l...

TRB's Airport Cooperative Research Program (ACRP) Synthesis 92: Airport Waste Management and Recycling Practices focuses on airport waste management and recycling practices that reduce impacts and costs to airports and their surrounding communities. The information in this study was acquired through a literature review, survey results from 35 organizations representing 36 airports from a range of geographic locations and airport classifications, and interviews of a subset of 21 airport waste management e...
