UNIT 1: TRANSPORTATION SYSTEM AND ROAD TRANSPORT NETWORK Flashcards
defined as movement of people and/or goods from one place to another.
Transportation
refers to the framework of routes within a system of locations, known as nodes
NETWORK
refers to a single link between two nodes that are part of a larger network
ROUTE
may either be
* Permanent/tangible routes (roads, rails and canals)
* Scheduled service/ less tangible routes (air and sea corridors, trains, public transit)
* Describes a structure which permits either vehicular movement or flow of commodity
* Consists of a system of interconnected ways designed to carry traffic
* Generally forms the most basic level of transport infrastructure in an urban area
* Links with all other areas, both within and beyond boundaries
ROAD TRANSPORTATION NETWORK
- network value is proportional to the square of connected nodes
- In reference to the Ethernet, the value of network is proportional to square of the number of connected uses in the system
Metcalfe’s law
Phenomenon whereby increased numbers of people improve the value of good or service
Network Effect
has high accessibility, represents the dominant element of the network
and the spatial structure it supports; point of highest accessibility, insignificant
accessibility with other nodes, implies high connectivity levels and redundancy
CENTER
also of significant levels of accessibility
SUB-CENTERS
is underdeveloped due to:
- terrains (mountains)
- geography (multiple islands)
- low government investment/funding in infrastructure
