18Transportation Engineering “For millions of Americans, girding for gridlock is a teeth teeth-grinding daily ritual. And with more cars on the road every day, engineers and other professionals trained to reduce traffic congestion are finding plenty of job opportunities”“PAY AND PERKS: $45,000 to $150,000. Producing tangible change is a source of job satisfaction for many.”U.S. News and World Report, February 18, 2002

21Transportation System Definition of Transportation ModesA transportation system is an infrastructure that serves to move people and goods efficiently. The transportation system consists of fixed facilities, flow entities, and a control component.Efficient = safe, rapid, comfortable, convenient, economical, environmentally compatible.
22Transportation System Major transportation subsystemsLand transportation: highway, railAir transportation: domestic, internationalWater transportation: inland, coastal, oceanPipelines: oil, gas, other
23Highway Transportation System Fixed facilities: roads, intersections, interchanges, service stations, etc.Flow entities: passenger cars, buses, trucks, pedestrians, etc.Control component: highway administration, local transportation agencies, transportation engineering.
24Highway Transportation Engineering DefinitionThe application of technology and scientific principles to the planning, functional design, operation, and management of roads, streets and highways, their networks, terminals, abutting lands, and relationships with other modes of transportation.Areas of highway transportation engineering:Planning of streets and highwaysGeometric design of road facilitiesTraffic operations and controlTraffic safetyMaintenance of road facilities and controls
