Intelligent transportation systems (ITS) provide a proven set of strategies for addressing the challenges of assuring safety and reducing congestion, while accommodating the growth in transit ridership and freight movement. This report presents information on the performance of deployed IT'S unde

The Enable Advanced Traveler Information System (EnableATIS) is looking ahead to a future operational environment that will support and enable an advanced, transformational traveler information services framework. This future framework is envisioned to be enabled with a much more robust pool of r

This Work Zone Best Practices Guidebook provides an easily accessible compilation of work zone operations practices used and recommended by various States and localities around the country. The Guidebook is a reference document that can be updated with new approaches, technologies, and practices

This document identifies successful practices and lessons learned from operations concepts at eight transportation management centers (TMCs) throughout the United States and Canada. The report provides background information about the importance of a concept of operations for a TMC and then descr

The Federal Highway Administration’s (FHWA) Road Weather Management brochure describes the challenges of road weather and its effect on highway safety, capacity, and reliability. At a high level, the brochure describes the current actions transportation system operators are taking to warn travele

The report Traffic Congestion and Reliability: Trends and Advanced Strategies for Congestion Mitigation provides a snapshot of congestion in the United States by summarizing recent trends in congestion, highlighting the role of travel time reliability in the effects of congestion, and describing

This publication evaluates the effectiveness of GDOT’s Towing & Recovery Incentive Program (TRIP). TRIP was introduced in early 2008 to provide monetary incentives to qualified towing operators for the quick clearance of large commercial vehicle incidents. A TRIP certified towing operator rec

The National Transportation Operations Coalition (NTOC) Action Team on Performance Measurement conducted this initiative to begin to define and document a few good measures for transportation operations agencies to use in measuring and documenting performance.

This article in the January-February 2013 issue of TR News provides a concise overview of research finding of SHRP 2 L06 on the institutional and organizational architectures necessary to perform effective TSM&O and the related guidance on improving agency capability in carrying out effective

This primer provides an overview of vehicle mileage fees and is structured to highlight:

This document discusses the VDOT NOVA Smart Travel Program Plan and envisions that ITS will make travel “smart” through the application of technology, as well as through automated, streamlined agency processes and procedures. The document emphasizes that the focus is on attaining operating effici

The intent of the Statewide Systems Operations Program (SSOP) is the “mainstreaming” of operations, such that the concept of “operating” its roadway system permeates the essential fabric of the Virginia Department of Transportation’s (VDOT) strategic and tactical activities on a daily basis. The

It’s been almost two months since I joined the National Operations Center of Excellence, so I thought it would be a good idea to pause and share what has transpired during this time. We had a very successful launch and presence during t

Guidebook: Project Management Strategies for Complex Projects TRB’s second Strategic Highway Research Program (SHRP 2) Report S2-R10-RW-2: Guidebook: Project Management Strategies for Complex Projects facilitates the application of a five-dimensional management approach for complex projects. The

This Guide is intended to be a high-level reference document for transportation planners, operators, and system managers. The reliability of the transportation system refers to the uncertainty or variability that system users experience in the time it takes to travel from one place to another—fro

This summary presentation summarizes the five key steps to incorporating reliability performance measures into the transportation planning and programming processes

The overall project was to develop the technical procedures for state DOTs and MPOs to fully integrate mobility and reliab

Introduction

ATDM is the dynamic management, control, and influence of travel demand, traffic demand, and traffic flow of transportation facilities. Through the use of available tools and assets, traffic flow is managed and traveler behavior is influenced in real-time to achieve operati

The intent of this project is to identify, develop, demonstrate and document measures of effectiveness that can be applied to validate the achievement of traffic signal operations objectives. Adaptive Signal Control Technology (ASCT) is an operational strategy that applies tactics aimed at achiev

Best Practice: The San Antonio Wrong Way Driving Initiative

Recently, a state DOT’s inquired about warning signs for motorists driving the wrong way. This has been an issue that many public agencies face. The Texas Department of Transportation had some of the same issues and has taken t

Almost 5 years after hurricanes Katrina and Rita battered Louisiana and Texas, respectively, public officials remain focused on the Nation's ability to safely evacuate large numbers of people. As a part of the Fiscal Year 2010 U.S. Department of Transportation (DOT) appropriations (Public Law 111

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

Testing describes a series of processes and procedures developed in the information technology community to verify and validate system performance. While some of the terms used in testing may be unfamiliar to transportation professionals, the core concepts and processes are not technically comple

This tenth edition of Freight Facts and Figures was developed collaboratively by the Federal Highway Administration and the Bureau of Transportation Statistics. It provides a snapshot of the volume and value of freight flows in the United States, the physical network over which freight moves, the

This guidebook examines traffic incident management practices that are implemented by transportation management centers on managed lanes. The document examines the unique operating environment of managed lanes from an incident management perspective. The roles of the transportation management cen

Ramp metering is a strategy used to regulate the volume of vehicles entering a freeway at a given time thereby seeking optimal freeway operations. Access to the freeway is controlled using a traffic signal that is powered by an algorithm that uses real-time system traffic data to determine the ra
