Transportation System Components c2

• Chapter 2 discusses transportation system components from an internal perspective

Infrastructure

• Guideways facilitate the movement of vehicles and can be either special-purpose or general-purpose
• Examples of guideways are highways, railroads, pipelines, and air corridors
• Terminals and stations provide locations for passengers, freight to transfer between vehicles or modes
• Examples of these are rail freight yards, container ports, airports, bus and transit stations, and bus/taxi stands

Vehicles

• Vehicles include automobiles, rail locomotives, airplanes, tractor trailers, truck trailers, railroad cars, and containers

Vehicle Characteristics

• Crashworthiness, degree of automation, energy source, weight, material, aerodynamics,and emissions are vehicle characteristics.

Equipment

• Equipment examples are loading cranes at container ports, railroad track maintenance equipment, airport baggage handling, and snow removal vehicles

Power Systems

• Power systems can include Internal Combustion Engines, Diesel Engines and Electric Motors
• Power systems can also include humans, animals, gravity, windmills, solar panels and tidal baffles

Fuel

• Fuel can include gasoline, natural gas, diesel, coal, and electricity
• Fuel can also be solar energy, tides/currents and wind

Control, Communications and Location Systems

• Control, communications and location systems can include humans, drivers and controllers such as air traffic controllers, and dispatchers
• Technology is needed as well such as Traffic Lights and Sensors

Summary: Transportation Physical System Components

• Infrastructure includes guideways, terminals, and stations
• Systems include vehicles, power, fuel, control, communications, and location systems

Transportation "Operators"

• Transportation operators include management, marketing, labor, strategic planning, and operations
• Marketing includes: intramodal, intermodal and intersectoral; where intersectoral is transportation vs. communications

Operations/Marketing "Tension"

• Marketing focuses on high-quality service to maximize revenue
• Operations focuses on minimizing cost through efficiency

Operators Continued

• Transportation operators also include maintenance management, information management, operations research and administration

Operating Plans

• Schedules, crew assignments, and vehicle distribution are all operating plans

Connection Patterns: Hub-and-Spoke

• There are connection patterns to decide on such as Hub-and-Spoke

Cost/Level-of-Service Trade-off

• It is important to decide whether to provide direct, high quality service from point A to point C
• Alternatively one can consolidate passengers at Node B with passengers from Node D into a single flight from B to C.
• There is a fundamental cost/level-of-service trade-off here

Contingency Planning

• Contingency planning is what is done when things go wrong
• Contingency Planning helps decide how to alter the operating plan to reflect changes in weather, demand for service, and accidents such as a derailment
