Interim Approval 17 for the Optional Use of Three-Section Flashing Yellow Arrow Signal Faces - 8/15/2014
The FHWA has issued Interim Approval 17 that permits the optional use for a protected/permissive turn phase of a three-section flashing yellow arrow (FYA) signal face that uses the middle section to show both the FYA and the steady yellow arrow. Agencies may also continue to use the four-section FYA signal face for protected/permissive turn phases that is described in Sections 4D.20 and 4D.24. This interim approval has no impact on the use of a three-section FYA signal face for a permissive only turn phase as described in Sections 4D.18 and 4D.22.

Please visit the RDE Web site to explore the data and resources that are available and learn more about the features included in Release 2.
Survey on Projects of National and Regional Significance - 6/5/2014
Section 1301 of SAFETEA-LU established a program to provide grants to States for Projects of National and Regional Significance (PNRS) to improve the safe, secure, and efficient movement of people and goods throughout the United States and to improve the health and welfare of the national economy. Under the provisions of MAP-21, $500,000,000 was authorized to be appropriated to carry out PNRS in fiscal year 2013. While no funds were appropriated in FY13, Section 1120 of MAP-21 requires the USDOT to develop a report to Congress that contains a comprehensive list of each project of national and regional significance that has been compiled through a survey of State departments of transportation; transit agencies, tribal governments, and multi-state or multi-jurisdictional groups. The comprehensive list will enable the Secretary to classify projects of regional or national significance and to develop recommendations on financing for eligible project costs. This survey is not a solicitation for a grant application. Response to the survey is voluntary and responding or not responding will not help, harm or directly influence the Secretary's evaluation for any future funding or solicitation for specific projects. For further information about PNRS, please contact Tamiko Burnell, firstname.lastname@example.org, 202-366-1200.
Operations Performance Measures and Management Program Road Map - 5/8/2014

Traffic Signal LED Module Specification Workshop and Informational Report for Snow Conditions - 4/29/2014
FHWA has released a research report on the issue of potential occurrence of snow and/or ice buildup on LED traffic signal lenses. The objectives were to identify significant environmental (i.e., weather) variables that may contribute to snow and ice buildup on LED traffic signal lenses and identify proactive approaches to eliminating or minimizing the negative effects. One of the unintended consequences of the transition to LED traffic signals lenses/indications is this lighting source does not produce heat in sufficient quantity to provide "melting" ability in climates that experience snow and ice conditions.

National Workshop Attracts "Thought Leaders" in Congestion Pricing - 1/2/2014
On July 9-10, 2013, 114 leaders in congestion pricing, managed lanes, and parking pricing convened in Seattle, WA to discuss recent successes and challenges to advancing congestion pricing in the United States. Much of the discussion centered on the important outcomes of project implementations, especially the Urban Partnership Agreement (UPA)/Congestion Reduction Demonstration (CRD) programs as well as the Value Pricing Pilot Program (VPPP). The primary objective of the conference was raising the awareness, advancing the state-of-the-practice, and identifying the research and technology transfer needs in support of deploying congestion pricing strategies in the United States.
