Study Notes
Transportation Overview
- Transportation encompasses the safe, efficient, reliable, and sustainable movement of people and goods across space and time.
- Transportation engineering applies technology and scientific principles to plan, design, operate, and manage transportation facilities for optimal, safe, and environmentally friendly movement of people and goods.
- Traffic engineering focuses on the planning, design, and operation of roads, streets, highways, and related networks, terminals, and surrounding areas, considering their interaction with other modes of transport.
Primary Objectives of Traffic Engineering
- To create a safe system for road traffic, including pedestrians and cyclists.
- To provide efficient management and operation of road transport networks.
- To incorporate sustainability, environmental impact, user comfort, convenience, and economic considerations.
Modes of Transportation
- Land (cars, buses, trains)
- Air (airplanes)
- Water (ships, barges)
- Pipelines (oil, gas)
- Cable and belt systems (industrial, ski lifts)
History of Transportation Engineering
- Early humans used their feet and domesticated animals.
- Machines and devices, like sleds and travois, improved carrying capacity.
- Development of trading routes created more permanent paths, which evolved into roads.
- Subsequent efforts focused on road maintenance and improving travel.
Critical Dimensions of Change in Transportation Systems
- Public values
- Technology
- Operational policies
- Demand
Components of Traffic Systems
- Vehicular traffic (cars, buses, trucks)
- Road conditions (motorways, highways)
- Driver characteristics (experience, licenses)
- Environmental conditions (weather, time of day)
- Control devices (signals, signs)
Characteristics of Transportation Systems
- Multidisciplinary
- Multisectoral
- Multiproblematic
- Multiobjective
- Multimodal
Elements of a Transportation System
- Infrastructure (roads, tracks, terminals)
- Vehicles (cars, trains, planes)
- Operators/Content (drivers, passengers, goods)
Urban Transit
- Specialized mode of transportation including buses, streetcars, light rail, and other forms of public transit.
- Commuters (making work trips)
- Captive riders (lacking automobile access)
Air Transportation
- Primarily for intercity, long-distance passenger travel.
- High line-haul speed
- Limited accessibility (less important for longer trips)
- Moderate aircraft capacities but high productivity.
Water Transportation
- Includes ocean shipping and inland waterways.
- Low speed and accessibility, but high capacity.
Pipelines
- Specialized freight system mainly for oil, petroleum, and natural gas.
- Low speed, high capacity, continuous flow.
- Low costs.
Cable and Belt Systems
- Frequently used for freight within complexes.
- Can also be used for specialized passenger transport (ski lifts, airport conveyors).
System for Financing Transportation
- User charges (fares, tolls, taxes)
- General fund revenues (taxes)
- Private investments
- Cross-subsidization (using revenues from one mode to fund another)
