Traffic Engineering is a branch of engineering that applies technology, science and human factors to the planning, design, operations and management of roads, streets, bikeways, highways, their networks, terminals and abutting lands.
The three functional areas within traffic engineering are:
Traffic Operations
Traffic Operations uses analysis, review, and application of traffic tools and data system, including crash and surveillance records as well as volume and other data gathering techniques necessary for traffic planning.
Traffic Design
Traffic Design consists of the design of traffic control devices and roadway operational design. Operational design concerns the visible features of a roadway dealing with such roadway elements as cross sections, curvature, sight distance, channelization and clearances. Operational design depends directly on the characteristics of traffic flow.
Traffic Planning
Traffic Planning includes the determination of personal and freight travel patterns on the basis of engineering analysis of the traffic and demographic characteristics of present, future and potential land use plans.
