TRB’s Transportation Research Record: Journal of the Transportation Research Board, No. 2404 consists of nine papers that examine percentile speeds from a maximum operating speed frontier; operational effects of access point designs on freeway managed lanes; sight distance standards based on observational data for risk evaluation of passing; freeway deceleration speed-change lanes; and, triangabouts as an alternative for intersection with non-through arterial movement. This issue also examines double-cro...

TRB’s National Cooperative Highway Research Program (NCHRP) Report 777: A Guide to Regional Transportation Planning for Disasters, Emergencies, and Significant Events uses foundational planning principles, case studies, tips, and tools to explain implementation of transportation planning for possible multijurisdictional disasters, emergencies, and other major events. In addition to the guide, there is a research report and a PowerPoint presentation describing the entire project.

TRB’s second Strategic Highway Research Program (SHRP 2) Capacity Project C39 has released a prepublication, non-edited version of a report titled Additional Pilot Tests to Improve TCAPP that documents the Charlottesville-Albemarle Metropolitan Planning Organization’s implementation and assessment of the Long Range Planning portion of the Transportation for Communities–Advancing Projects through Partnerships (TCAPP) Decision Guide.

TRB’s second Strategic Highway Research Program (SHRP 2) Capacity Project C39 has released a prepublication, non-edited version of a report titled Use of TCAPP Decision Guide to Improve Environmental Agency Coordination for Hoopstick Creek Bridge Replacement that evaluates and proposes enhancements to the Transportation for Communities–Advancing Projects through Partnerships (TCAPP) collaborative planning tool. The report explores the tool’s value in providing guidance to facilitate project partners to w...

TRB’s Transit Cooperative Research Program (TCRP) Synthesis 112: Maintaining Transit Effectiveness Under Major Financial Constraints discusses transit agencies that implemented plans to increase their cost effectiveness and how the agencies communicated with their communities during challenging fiscal circumstances.

TRB’s Airport Cooperative Research Program (ACRP) Synthesis 57: Airport Response to Special Events explores how airports plan, manage, and recover from special events in order to help minimize the event’s effects on an airport’s regular operations. The synthesis explores issues related to planning, organizing, and applying lessons learned, as well as addressing potential surprises and impacts on operations and customer services related to a variety of non-aeronautical events that occur both on and off an...

TRB’s second Strategic Highway Research Program (SHRP 2) has released a project brief that explores the software tool, the Work Zone Impacts and Strategies Estimator (WISE). WISE is designed to assist program managers in sequencing programs of projects. In addition, it is designed to help planners and engineers evaluate the impacts of work zones to determine strategies to reduce these impacts. SHRP Renewal Project R11 produced  Strategic Approaches at the Corridor and Network Level to Minimize Disru...

TRB’s National Cooperative Highway Research Program (NCHRP) Synthesis 465: Permanent Signs Mounted on Median Barriers reports on the current state of practice for mounting permanent highway signs on top of rigid median barriers throughout the United States.

TRB’s Airport Cooperative Research Program (ACRP) Research Results Digest 21: Best Practices for General Aviation Aircraft Fuel-Tank Sampling estimates the discard amounts from fuel testing samples that are entering the stormwater run-off system, and develops best practices for proper disposal of the fuel-tank samples.

TRB’s National Cooperative Highway Research Program (NCHRP) Report 778: Bridge Stormwater Runoff Analysis and Treatment Options presents information and an analysis process for identifying cost-effective, pollution-reducing strategies for management of stormwater runoff from highway bridges. Five spreadsheet analysis tools accompany the report: NCHRP Bioretention Evaluation Tool NCHRP Dry Detention Evaluation Tool NCHRP PFC Evaluation Tool NCHRP Sand Filter EvaluationTool NCHRP Swale Evaluation Tool
