Guidelines for Temporary Traffic Control
The primary function of temporary traffic control (TTC) is to provide for the safe and efficient movement of vehicles, bicyclists, and pedestrians (including persons with disabilities in accordance with the Americans with Disabilities Act) through or arround TTC zones while reasonably protecting workers and equipment. The typical application diagrams shown in this manual represent minimum requirements for typical situations. USDOT & FHWA.

Signal Timing on a Shoestring PDF
Research and experience has shown that retiming traffic signals is one of the most cost-effective tasks that an agency can do to improve traffic flow and safety. This report examines various cost effective techniques that can be used to generate good signal timing plans that can be employed when there are insufficient financial resources to generate the plans using conventional techniques.

Synthesis of Traveler Choice Research: Improving Modeling Accuracy for Better Transportation Decisionmaking
Over the last 50 years, advances in the fields of travel behavior research and travel demand forecasting have been immense, driven by the increasing costs of infrastructure and spatial limitations in areas of high population density together with externalities in these areas. This report provides a synthesis of the state of knowledgfe in travel behavior research and identifies gaps in existing data, methods, and practices that must be filled to meet the analysis needs of an emerging class of supply - and demand-side interventions that seek to leverage the opportunities of real-time information.

Traffic Monitoring in Recreational Areas
In an effort to improve /lend consistency to traffic monitoring in recreational areas, the Coordinated Technology Implementation Program tasked the Office of Federal Lands Highway-Federal Highway Administration (FHWA) with conducting an assessment of the nationwide practices for recreational traffic data collection. A review of pertinent literature related to recreational traffic data collection was conducted. A targeted survey of various State and local agencies responsible for traffic monitoring was administered. A workshop focused on traffic monitoring in recreational areas was also conducted. FHWA, August 2010.

Understanding Long-Distance Traveler Behavior - Supporting A Long-Distance Passenger Travel Demand Model pdf
Long-distance trips in the United States can take 2 days or 2 weeks and may involve cars, buses, planes, or all three. Whether for business, to see family, or visit a national park, such a variety of trip characteristics requires a detailed understanding of traveler needs. Exploring new ways to model long-distance traveler behavior and better identify the required supporting infrastructure is the goal of “Foundational Knowledge to Support a Long-Distance Passenger Travel Demand Modeling Framework,” a Federal Highway Administration (FHWA) Exploratory Advanced Research (EAR) Program study awarded to Resource Systems Group (RSG).
