PDF
The Urban Congestion Report (UCR) is produced on a quarterly basis and characterizes the most recent traffic congestion and reliability trends at the national and city level. Each quarterly UCR compares data from the most recent three months to the same three months in the previous year.
This report documents an evaluation of outcomes associated with Roadside Revegetation: A Practical Guide to Working with Native Plants, a 2007 guide encouraging agencies to adopt improved roadside revegetation practices.(1) It should be of interest to natural resource practitioners responsible for the design and implementation of revegetation proje

Understanding the choices that drivers, bicyclists, and pedestrians make is critical to improving the safety and efficiency of the Nation’s roadways. The Federal Highway Administration (FHWA) seeks to understand the technological challenges of advancing the use of federated simulation and modeling and the different uses that researchers and practit

In 2013, the Wisconsin Department of Transportation (WisDOT) began updating the passenger component of its statewide travel demand model, while also updating the model's conventional, trip-based freight element. As a result of significant advances in the state of the practice for behavior-based freight modeling, planners within WisDOT wanted to exp

In recent years, state transportation agencies (STAs) have made investments in creating 3D engineered models in design, but few STAs are realizing the benefits of using these models in construction engineering and inspection. Agencies that use the models and related survey technology report time savings, safety improvements, increased confidence an

Eco-drive is one of many techniques that have been developed to increase vehicle fuel efficiency. Connected Vehicle (CV) data is now being leveraged to allow vehicles to cooperate better within current and future environments vis-a-vis traffic conditions, signal timing, and terrain information. This study investigates the use of vehicle automation

FHWA's Synthesis of Approaches for Addressing Resilience in Project Development (2017) study evaluated engineering approaches for assessing current and future weather hazards, and developed solutions and methodologies that transportation agencies may apply to increase the resilience of transportation assets and systems.
The Development of Crash Modification Factors (DCMF) program conducted safety evaluations of edge-line rumble stripes (ELRSs) on rural two-lane horizontal curves for the Evaluation of Low-Cost Safety Improvements Pooled Fund Study. This study evaluated the application of ELRSs on rural two-lane horizontal curves. ELRSs are a variation of common sho

The FHWA Work Zone Driver Model v1.1 was created for planners and engineers, so they can more accurately predict the operational impacts of freeway work zones, such as queues, travel times, and delays. The software interfaces with commercially available microsimulation tools and alters car-following algorithms— derived from empirically collected da

Public-Private Partnership (P3) handback experience is very limited the U.S. and internationally. This paper analyzes the handback experience in three highway P3 projects: East-Link Bridge in Dublin, Ireland, Highway 4 (VT4 Järvenpää-Lahti) in Finland and M4 Tollway in New South Wales, Australia. Two of the projects did not have any material handba

This report summarizes the proceedings of the Pennsylvania Roadway Departure Safety Peer Exchange held in Harrisburg, Pennsylvania, sponsored by the Pennsylvania Department of Transportation (PennDOT) and the Federal Highway Administration (FHWA) Office of Safety's Roadway Safety Professional Capacity Building Program.
Located in the Pacific Northwest, Metro serves as Portland, Oregon's metropolitan planning organization (MPO). As an international gateway and domestic freight hub, the region is particularly influenced by the dynamic trends affecting distribution and logistics. Thousands of Oregon companies depend on Portland's marine, rail, air, and road faciliti

CAV technologies offer potentially transformative societal impacts—including significant mobility, safety, and environmental benefits. The Federal Highway Administration (FHWA) has led the development, research, and standards-making of these technologies, and is currently developing deployment approaches and guidance.
This report highlights key recommendations and noteworthy practices identified at “Rethinking I-94: MnDOT Peer Exchange” held on August 15-16, 2017 in St. Paul, Minnesota. This event was sponsored by the Transportation Planning Capacity Building (TPCB) Peer Program, which is jointly funded by the Federal Highway Administration (FHWA) and Federal Tr

Traffic Volume Trends is a monthly report based on hourly traffic count data reported by the States. These data are collected at approximately 5,000 continuous traffic counting locations nationwide and are used to estimate the percent change in traffic for the current month compared with the same month in the previous year. Estimates are re-adjuste
