A strategic plan and series of research roadmaps for AASHTO’s Committee on the Environmentand Sustainability has been completed under a project of the National Cooperative Highway Research Program (NCHRP 25-25/Task 95). The plan includes high level goals and objectives for the full committee, as well as each of the four subcommittees. It also includes research roadmaps for each of the subcommittees and additional interest areas including: the Subcommittee on Air Quality, Climate Change, and Energy; Subcommittee on Communities and Cultural Concerns; Subcommittee on Environmental Process; Subcommittee on Natural Resources; as well as additional topics of Extreme Weather Events and Stormwater. For more information, link to the Strategic Plan. (8-31-15)

The Florida Department of Transportation has conducted a study of 24-hour traffic peaking characteristics and the relationship to off-hour levels of service. The variation of volume between peak hours, peak-shoulders and off-peak hours of service on both limited-access and arterial roads were examined in order to inform planning with regard to road usage, lane construction, speed limit decisions and other issues. The study found that severe congestion occurred less than 50 percent of the time in most facilities. Also, freeways and other limited-access highways saw severe congestion for four hours per day and moderate congestion for 10 hours, while arterial roads saw severe congestion for five hours and moderate levels for 11 hours. For the full report, link to Twenty-Four Hour Peaking Relationship to Level of Service and Other Measures of Effectiveness. (8-19-15)

The Federal Highway Administration has announced the organizations that have been selected for implementation and technical assistance through the 6th round of the Second Strategic Highway Research Program (SHRP2). The organizations hail from 18 states and are carrying out projects for proof of concept and user incentives and as lead adopters, including utility investigation technologies, the Work Zone Impacts and Strategies Estimator Software and PlanWorks. In addition, the anticipated products for Round 7 include a focus on renewal through bridge design and construction materials and reliability work through data toolkits and planning models. The administration also has launched the “Milestones” newsletter highlighting specific achievements in the SHRP2 program for capacity, renewal, reliability and safety, such as the Traffic Incident Management Responder Training Program’s effort to trail all 1 million emergency responders in the country on incident response. For more information, link to projects announcement or Milestones newsletter. (8-12-15)
