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

In a featured article in the May-June 2014 issue of the TR News, TRB Directors highlight the enhancements to the TRB Annual Meeting exhibit hall. Booth sales open on July 24, 2014 for all organizations and companies that plan to exhibit at the meeting.

TRB’s National Cooperative Highway Research Program (NCHRP) Research Results Digest 387: Alternative Delivery Methods for Winter Maintenance Operations develops a decision-making framework to guide public road agencies’ delivery of winter maintenance operations.

TRB’s Transit Cooperative Research Program (TCRP) Report 170: Establishing a National Transit Industry Rail Vehicle Technician Qualification Program—Building for Success describes a system of qualification that has been developed for rail vehicle technicians. This qualification system is available for implementation through the Transportation Learning Center. The program integrates national training standards, progressive classroom curricula and introductory courseware, on-the-job learning modules, an ap...

TRB’s Innovations Deserving Exploratory Analysis (IDEA) Safety Programs Project 23: Reducing Wheel Climb at Switch Points to Reduce Derailments presents survey results and an engineering analysis of international maintenance practices for reducing risk of wheel climb at switch points, and describes the potential application of these practices for U.S. freight and passenger railways. As a result of the study, the project developed and evaluated a series of hand held gauges modified to reflect U.S. conditi...

TRB’s Airport Cooperative Research Program (ACRP) Web-Only Document 17: Research Methods for Understanding Aircraft Noise Annoyances and Sleep Disturbance explores the development and validation of a research protocol for a large-scale study of aircraft noise exposure-annoyance response relationships across the U.S. The report also highlights alternative research methods for field studies to assess the relationship between aircraft noise and sleep disturbance for U.S. airports.

The full PDF version of the January-February issue is now available.  This issue of the TR News focuses on the effects the boom in the domestic energy industry is having on low-volume roadways in Texas; practical findings from a 26-state pooled-fund study on winter maintenance challenges; the mega-project under way to replace the Gerald Desmond Bridge in the Port of Long Beach, California; and the implementation of SHRP 2 accelerated bridge construction pilot projects in New York and Iowa. This issu...

TRB’s Transportation Research Record: Journal of the Transportation Research Board, No. 2402 consists of eight papers that examine truck impact hazards for interstate overpasses; experimental microsimulation modeling of road safety impacts of bus priority; fatigue level and driving performance of professional drivers; and, turboroundabouts. This issue also explores intersection capacity, safety, and emissions; noncompliant driver behavior at single-lane roundabouts; construction of double-lane roundabout...

TRB’s Airport Cooperative Research Program (ACRP) Synthesis 58: Safety Reporting Systems at Airports describes safety reporting methods and systems for airports certificated under Title 14 Code of Federal Regulations Part 139 by assessing current practices, processes, and systems used to collect and analyze safety data and information.
