Appendix B: The Language of Traffic Engineering CONSULTING Research Brief Volume No. 15 The Language of Traffic Engineering Tra ic Engineering, anra ic ngineers, offen use technical terms or jargon that may be confusing or tough to understand even within the context of a sentence. Key terms and acronyms that can generally be found in all types of traffic studies are defined in this document. Types of Studies Access Management — The practice of government agencies limiting the amount of intersections (both public roadway crossings and private driveways) along a roadway corridor based on the function of the roadway to improve safety and mobility while streamlining access. Corridor Study — A transportation review and analysis of the existing and future traffic operations of a roadway segment. Varies in length from a couple blocks to a few miles and typically covers all modes of travel. Intersection Control Evaluation (ICE) Report — A document that examines and determines the most appropriate type of control (stop sign, signal, roundabout, or other) at one or more intersections. Safety Study — An examination of crash records to identify potential trends, issues, and problem intersections/ corridors. Usually includes potential mitigation options expected to decrease crash rates in the future. Speed Study — A review of existing travel speeds and the corridor characteristics to determine if speeding is an issue, the appropriate speed to post as the limit, and/or areas to provide reduced speed warnings. Traffic Impact Study (TIS) — A document that addresses the expected traffic impacts of a development and, if necessary, mitigation options that will reduce or eliminate negative impacts. Also referred to as a Traffic Impact Analysis. Transportation Plan — A document developed by a government agency to take inventory of their transportation network, identify concerns or issues and lay out the path for improvement of the system. Travel Demand Management Plan (TDMP) — A plan that documents the existing infrastructure around a site, including transit and non -motorized vehicle options, and develops measures to be implemented to encourage those alternative modes of travel. Warrant Evaluation — Review of traffic volumes and other characteristics at an intersection against thresholds to determine if a traffic signal or other traffic control option is needed/warranted. Safety N111101/4 Tt^ frrrulugy Parking Management COP trot if Traffic Engineering Intro -modal Interactions Litton A Structure Multi -modal Interactions Source: ETH Zurich Traffic Engineering is a branch of civil engineering that focuses on the safe and efficient movement of people and vehicles. It is part science and part art, requiring not only technical skills for analysis but an understanding of motivations in choosing travel routes. Key Organizations AASHTO — American Association of State Highway and Transportation Officials. A nonprofit, nonpartisan association representing transportation departments with a primary goal of fostering the development, operation, and maintenance of an integrated national transportation system. DOT — Department of Transportation. Government organizations within federal and state agencies dedicated to serving the transportation needs of the community and typically responsible for study, design, operation, and maintenance of all facets of transportation. FHWA — Federal Highway Administration. An agency within the US Department of Transportation that supports State and local governments in the design, construction, and maintenance of the highway system. ITE — Institute of Transportation Engineers. An international educational and scientific association of transportation professionals who are responsible for meeting mobility and safety needs.
