UNIT 1: TRANSPORTATION SYSTEM AND ROAD TRANSPORT NETWORK Flashcards
(51 cards)
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
PHILIPPINE Transportation
PHILIPPINE Transportation Classified as:
National Highway Network
National Expressway Network
- Series of public roads that provide inter-city connection
- Numbered N1 to N82
- N1 to N10 :Main routes or priority corridors connecting three or more
cities - N11 to N82 : Roads linking two cities
- Mostly single and dual carriageways linking two or more cities

SRNH
Strong Republic Nautical Highway
919 km integrated set of highway segments and ferry routes
covering 17 cities (2003)
Strong Republic Nautical Highway (SRNH)
MODE OF TRANSPORT: (Air)
- airplanes
- the organization, arrangement, guidance and control of both stationary and
moving traffic
TRAFFIC MANAGEMENT
- Traffic signs and markings
- follow International standards by Vienna Convention, 1968, but neither
conform in color nor shape as per standard - Generally insufficient
- For HUA’s: hardly visible and recognized due to giant billboards
Traffic Control devices
- primary policy, planning, programming, coordinating, implementing and
administrative entity of the executive branch on the promotion, development
and regulation of a dependable and coordinated network of transportation
system, and a fast, safe , efficient and reliable services
