Traffic Control Devices Committee AHB50

TCD is a technical standing committee AHB50 of the Transportation Research Board (TRB) of the National Academies. TCD is concerned with the development, design, application, and evaluation of traffic control devices, and their effect on traffic operation and safety.

Traffic Flow Theory and Characteristics Committee AHB45

This committee is concerned with the development, validation, and dissemination of theoretical, experimental, and applied research on traffic flow theory and traffic flow characteristics and the determination of the relationship of traffic flow theory and traffic flow characteristics to the planning, design and operation of transportation systems.

Traffic Signal Systems Committee AHB25

The mission of the Committee is to provide leadership and serve as the TRB focal point in promoting, implementing, operating and maintaining traffic management systems and strategies including Intelligent Transportation Systems, to enhance the efficiency, safety and environmental conditions on freeways and in freeway corridors.

Transportation Network Modeling committee ADB30

The committee will promote research and information exchange in transportation network modeling, an interdisciplinary field spanning Computer Science, Logistics, Mathematics, Operations Research, Telecommunications, and Transportation Science. The committee will also focus on: the understanding and modeling of the technological and behavioral factors affecting the performance of transportation systems; modeling the interactions between the infrastructure and transpiration networks; and the development and use of models to evaluate the quantity and quality of transportation facilities and services. The committee will serve as a focus for the development, adaptation, and implementation of quantitative and computer-based methodologies for the above purposes. The committee will cut across traditional modal boundaries, seeking unifying conceptual and methodological frameworks, yet highlighting modal differences. As such, it will foster effective and rapid sharing of information and experiences among researchers, practitioners, regulators and decision makers.

Visualization in Transportation committee ABJ95

The scope of the Committee is to foster and disseminate collaborative exchange and research that enhances the usable knowledge of visualization methods and technologies for their potential in addressing critical transportation issues of today, as well as promoting innovative approaches to society's transportation needs of the future.
