Overview of Transportation Engineering
What is TRANSPORTATION ?
Transportation System Definition of Transportation Modes
A transportation system is an infrastructure that serves to move people and goods efficiently . E fficient = safe, rapid, comfortable, convenient, economical, environmentally com patible.
Transportation System Major transportation subsystems ortation: highway highway,, rail Land transportation:
Air transportation: domestic, international Water transportation: inland, coastal, ocean Pipelines: oil, gas, other

Evolution of Transportation
The TGV (French ( French:: Train à Grande Vitesse , meaning high-speed train ) is France France's 's high-speed rail service
A TGV the fastest rail rail journey with a start to stop average average speed of 279.4 km/h (173.6 [2][3] mph),
surpassed by the Chinese CRH service Harmony express on the WuhanGuangzhou HighSpeed Railway in 2009.
Maglev (magnetic (magnetic levitation), levitation), is a system of transportation that suspends, guides and propels trains, using magnetic levitation levitation from a very large number of magnets for lift and propulsion.
A hydrogen vehicle is an alternative fuel vehicle that uses hydrogen as its onboard fuel for power
The current land speed record for a hydrogen-powered hydrogen-powered vehicle vehicle is 286.476 mph (461.0 (461.038 38 km/h) km/h)
31
Now a days Supertankers Supertankers has a length length overall of of 380.0 metres (1,246.7 (1,246.7 ft) and a cargo capacity capacity of 3,166,353 barrels (503,409,900 (503,409,900 l).

33
Jet aircraft propelled by jet by jet engines generally fly much faster than propeller propeller-powered powered aircraft aircraft and at at higher higher altitudes altitudes as high as 33,000 33,000 to to 49,000 ft.
34
A jumbo jet is a large aircraft, most commonly the Boeing 747. The 747-400, is the fastest airliners in service with a high-subsonic cruise speed of 570 mph, 920 km/h. It can accommodate more than 500 passengers.

What is TRANSPORTATION ENGINEERING ?
Transportation Engineering One of the specialty areas of civil engineering ± Development of facilitie s (roads , railways, airports, Bus stops,..) for the movement of good s and people
± Planning, design, operation and maintenance
Multidisciplinary study
Transportation Engineering
Transportation Engineering An interesting interesting / exciting exciting area ! Employers ± 50% government ± 40% consultants ± 5% research, teaching ± 5% other rail, trucking firms, etc.
Highway Engineering The application of technology and scientific principles to the planning, f unctional design, operation, and management of roads, streets and highways, their networks, terminals, abutting lands, and relationships with other modes of transportation. Areas of highway engineering: ± Planning of streets and highways ± Geometric design of road facilities ± Traffic operations and control ± Traffic safety ± Maintenance of road facilities and controls
