This brochure describes two case studies for applying simulation models in combination with travel demand models: 1) the traditional approach performing these adjustments outside of the travel demand model; and 2) advanced approach that makes many of the demand adjust
Active management of transportation and demand can include multiple approaches spanning demand management, traffic management, parking management, and efficient utilization of other transportation modes and assets. Some example approaches are included in the table. Evaluating and Recommending Dyn
Active management of transportation and demand can include multiple approaches spanning demand management, traffic management, parking management, and efficient utilization of other transportation modes and assets. An agency can deploy a single ATDM approach in order to capitalize on a specific b
This case study summarizes an effort involving the use of archived data for operations planning conducted by the Metropolitan Transportation Commission (MTC) in the San Francisco Bay Area.
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
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
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
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
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
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

FHWA’s Localized Bottleneck Reduction Initiative (LBR) program focuses attention on mitigating the operational causes of recurring congestion “hot spots” (i.e., traffic bottlenecks) at ramps, merges, lane drops, intersections, weaves, etc. One of the efforts of the LBR program is to encourage age
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
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

As part of the effort to encourage major metropolitan safety/service patrols to transition to Full Function Safety/Service Patrols (FFS/SP) and to establish consistency among these programs, the FHWA has published the Full Function Safety/Service Patrol Handbook, developed training standards, and
The objectives of this outreach initiative are to:
Encourage State and local/tribal governments in the top 40 metropolitan areas to adopt and promote effective implementation all three SQC laws. Create awareness among motorists of these laws, and promote compliance. Encourage the auMore and more, transportation system operators are seeing the benefits of strengthening links between planning and operations. A critical element in improving transportation decision-making and the effectiveness of transportation systems related to operations and planning is through the use of an
An objectives-driven performance-based approach to planning for management and operations includes the following elements conducted in collaboration with operating agencies and other stakeholders within the region:
Engage transportation planners and operators, as well as non-traditionalThis guidebook provides information on how to create an objectives-driven, performance-based congestion management process. While the focus of this guidebook is on the CMP, the principles of objectives-driven, performance-based planning can also be applied to other aspects of regional concern (sa
The purpose of this document is to develop guidelines for the creation, implementation, and operation of a Virtual TMC. These guidelines identify the recommended processes, procedures, roles, and responsibilities for planning, implementing and operating a Virtual TMC. This report also presents ca
This document is the second of two reports that explore the potential for the use of rural Interstate Highway corridor rights-of-way for the deployment of fiber optic cable and/or wireless communication infrastructure, across multiple States linked by the Interstate Highway system. The firs
The objective of this handbook is to provide direction, guidance, and recommended practices for test planning, test procedures, and test execution for the acquisition, operation, and maintenance of transportation management systems and Intelligent Transportation Systems (ITS) devices.
