Lesson 3 Flashcards
the application of technology and scientific principles to the planning, functional design, operation and management of
facilities for any mode of transportation in order to provide for the safe, rapid, comfortable, convenient, economical and environmentally compatible movement of people and goods.
Transportation Engineering
is an art and science of planning, designing and constructing of roads and the maintenance and rehabilitation of finished roads.
Highway Engineering
Why is transportation important in world development?
- It links residences to employment
- It links producers of goods with their users
- It gives access to health, education and other amenities.
The physical plant of most transportation systems consists of four basic elements
- Links
- Vehicles
- Terminals
- Management and labor
the roadways or tracks connecting two or more points
Links
the means of moving people and goods from one node to another along a link.
Vehicles
the nodes where travel and shipment begins or ends.
Terminals
the people who construct, operate, manage and maintain the links, vehicles and terminals.
Management and labor
Nine Categories of Human Behaviour that are affected by Transportation
- Locomotion (passengers, pedestrians)
- Activities (vehicle control, maintenance, community life)
- Feelings (comfort, convenience, enjoyment, stress, likes, dislikes)
- Manipulation (modal choice, route selection, vehicle purchase)
- Health and safety (accidents, disabilities, fatigue)
- Social interaction (privacy, territoriality, conflict, imitation)
- Motivation (positive or aversive consequences)
- Learning (operator training, driver education)
- Perception (images, mapping)
three basic attributes of Transportation systems
- Ubiquity
- Mobility
- Efficiency
the amount of accessibility of the system, directness of routing between access points, and the system’s flexibility to handle a variety of traffic conditions.
Ubiquity
the quantity of travel that can be handled.
Mobility
the relationship between the cost of transportation and the productivity of the system.
Efficiency
Nine components of ITS (Intelligent Transportation Systems)
- Smart Traffic signal control systems
- Freeway management systems
- Transit management systems
- Incident Management systems (IMS)
- Electronic toll collection on bridges and roads
- Electronic fare payment systems
- Emergency response
- Travel information systems
- Route guidance system
sense heavy traffic flows at road intersections and adjust the timing of signals automatically to accommodate the flows.
