Traffic incident management (TIM) is a planned and coordinated program to detect and remove incidents and restore traffic capacity as safely and as quickly as possible. Over time, various tools and strategies have been developed and implemented in an effort to improve overall TIM efforts. The nat
The primary objective of this research was to identify significant environmental (i.e., weather) variables that may contribute to snow and ice buildup on LED traffic signal lenses. If a subset of variables can be identified that may predict the potential occurrence of snow and/or ice buildup on L
The Federal Highway Administration (FHWA) Office of Operations sponsored a research project to develop new and updated methodologies, data sets, and content for the Highway Capacity Manual (HCM) that will better reflect the demand and traffic flow behavior that results from the application of Act
How transportation agencies can benefit from MUTCD P2P: The FHWA Peer network provides access to valuable guidance and information as well as input from people who share a similar background and have faced the same challenges. The list of benefits is long, but here are just a few that you can exp
Research was conducted to explore and identify the issues with and approaches to applying the Rule to design-build projects and how this affects the project development process. In-depth research was done through two case study sites to further examine the issues and identify successes, challenge
Many agencies use intelligent transportation system (ITS) devices to monitor traffic flow and detect disruptions on transportation networks. These devices can measure average speed, occupancy, and travel time, which can be used to determine performance of the system and provide traveler informati
The purpose of this technical memorandum is to identify key aspects of the FHWA Work Zone Safety and Mobility Rule (the Rule) and how they might apply to design-build (DB) projects in a different manner than they apply to design-bid-build (DBB) projects. The Rule was originally designed for DBB p
Freight Facts and Figures 2011 is a snapshot of the volume and value of freight flows in the United States, the physical network over which freight moves, the economic conditions that generate freight movements, the industry that carries freight, and the safety, energy, and environmental implicat
Project Purpose:
A research project sponsored by FHWA was to develop new and/or updated methodologies, data sets, and content for the Highway Capacity Manual (HCM) that would better reflect the demand and traffic flow behavior that result from the application of Active Transportation an
