Use of Narrow Lanes and Narrow Shoulders on Freeways: A Primer on Experiences, Current Practice, and Implementation Considerations

This primer provides information to policy makers, transportation agency managers, designers and operators on the use of narrow lanes and narrow shoulders to improve capacity within an existing roadway footprint. Much of the information contained in the primer is presented in the broader context of both Performance Based Planning and Programming (PBPP) and Performance — Based Practical Design (PBPD). Primer contents include case studies on the use of narrow lanes, issues and approaches for analyzing the operational and safety impacts of narrow lanes and narrow shoulders, and the role of transportation systems management and operations (TSMO) in support of narrow lanes operations.

Talking Freight Seminar on September 21, 2016: Accommodating Trucks in Innovative Design Intersections and Interchanges

This webinar will discuss the reasons why many different types of innovative intersections are becoming more popular across the United States, describe the state of the practice on how agencies are factoring in trucks and freight needs when planning and designing those intersections, and review on-going efforts in two states – Oregon and Ohio – that demonstrate how this is done within States at the program and project levels.

Urban Congestion Trend Reports for 2015 Available

2017 SOLAR ECLIPSE Transportation Fact Sheet for State and Local Departments of Transportation

To help the 14 states under the path of the first solar eclipse to transverse the continental United States since 1918, FHWA has prepared the 2017 Solar Eclipse Transportation Fact Sheet for State and Local Departments of Transportation. With approximately 200 million people living within a day's drive of the August 21, 2017 solar eclipse, the fact sheet was designed to alert state and local DOTs of the eclipse, provide the link for events and festivals to celebrate the event in the 14 states; and if appropriate, to provide information should the states need to develop transportation plans.

Regional Assessment of Weather Impacts on Freight

This project follows up on a study completed for the Federal Highway Administration (FHWA) in 2012 that provided a national estimate of weather-related delay affecting the trucking industry. The initial estimate indicated that weather-related delay costs the industry $8 billion to $9 billion annually. The goal of this study is to conduct a more detailed assessment of the impacts of adverse weather on freight movement in 13 diverse geographic regions, including both urban and rural corridors. The analysis presented in this report indicates that, overall, weather events have a significant negative impact on traffic speeds—and, therefore, the freight industry—when analyzed at the regional level. In this report's study area, which focuses solely on a limited set of major highways, decreased traffic speeds due to weather events are estimated to cost the freight industry $3.8 million per year. The study found that ice, snow, fog, heavy rain, wind, and extreme temperature events were the most correlated with reduced traffic speeds, with the largest decreases occurring during the first hour of storms. Adverse weather was shown to have a greater correlation with decreased traffic speeds during peak hours.

Integrated Corridor Management and Traffic Incident Management: A Primer

This primer will examine both how traffic incident management (TIM) can be integrated into an integrated corridor management (ICM) approach, as well as the many benefits resulting from ICM that can contribute to the advancement of TIM programs.

Shared Mobility: Current Practices and Guiding Principles

This primer provides an introduction and background to shared mobility; discusses the government's role; reviews success stories; examines challenges, lessons learned, and proposed solutions; and concludes with guiding principles for public agencies. The primer provides an overview of current practices in this emerging field, and it also looks toward the future in the evolution and development of shared mobility.

Congestion Pricing - A Primer: Effective Approaches to Streamlining Back Office Operations

The document explores the range of back office issues that have arisen on congestion pricing projects throughout the United States. The issues are organized into eight categories: policy decisions, interoperability back office efficiency, enforcement, data analysis and warehousing, transparency, privacy, and private sector involvement.

Integrated Corridor Management and Freight Opportunities

This primer examines how freight can be incorporated into an integrated corridor management (ICM) approach, as well as the benefits of ICM in addressing the freight challenge.

Integrated Corridor Management, Transit, and Mobility on Demand

This primer examines how both public transportation and mobility on demand can be incorporated into an integrated corridor management approach.

Guide to Project Coordination for Minimizing Work Zone Mobility Impacts

This new publication provides guidance on using work zone Project Coordination (PC) to minimize work zone impacts and produce time and achieve cost savings. This Guide presents key concepts of PC, examples of useful tools to facilitate PC, and case studies of how PC was used to improve agency management of complex construction programs.

FHWA Publishes Proposed Freight and System Performance Measure Rules

The U.S. Department of Transportation’s Federal Highway Administration today published a rulemaking that proposes new performance measures to assess system performance, freight movement, and the CMAQ program. The proposed regulation calls for an increased level of transparency and accountability in establishing and achieving targets for performance impacting commuters and truck drivers.

National Symposium on Work Zones and Large Trucks

The National Symposium on Work Zones and Large Trucks was held as a one-day event at the Hyatt Regency Jacksonville Riverfront Hotel in Jacksonville, Florida, on April 13, 2015. The objective of the symposium was to exchange experiences and identify solutions to further improve large truck safety and mobility in and around work zones.

Part-Time Shoulder Use Guide

The FHWA Office of Operations has developed a guide to assist agencies in planning, designing, implementing, and operating part-time shoulder use strategies that can be used to relieve congested bottlenecks and improve traffic flow and congestion related crashes. The guide was developed based on interviews with agencies that have deployed shoulder use treatments, interviews with various FHWA subject matter experts, and research on relevant safety and operations effects and analytical techniques. This guide outlines a process and covers a range of topics that will help agencies evaluate or advance shoulder use concepts in their states or regions in a more consistent manner.
