Transportation System
Definition of Transportation Modes
• A transportation system is an infrastructure that
serves to move people and goods efficiently. The
transportation system consists of fixed facilities,
flow entities, and a control component.
• Efficient = safe, rapid, comfortable, convenient,
economical, environmentally compatible.
Transportation System
Major transportation subsystems
• Land transportation: highway, rail
• Air transportation: domestic, international
• Water transportation: inland, coastal, ocean
• Pipelines: oil, gas, other

Highway Transportation System
• Fixed facilities: roads, intersections,
interchanges, service stations, etc.
• Flow entities: passenger cars, buses, trucks,
pedestrians, etc.
• Control component: highway
administration, local transportation
agencies, transportation engineering.
Highway Transportation Engineering
• Definition
The application of technology and scientific principles to the planning,
functional design, operation, and management of roads, streets and
highways, their networks, terminals, abutting lands, and relationships
with other modes of transportation.
• Areas of highway transportation engineering:
– Planning of streets and highways
– Geometric design of road facilities
– Traffic operations and control
– Traffic safety
– Maintenance of road facilities and controls
Governmental Impact
• National Regulations
– National model of a Manual of Uniform Traffic Control
Devices
– Speed limits
– Right turn on red
– Minimum drinking age of 21
– National architecture of ITS (standards)
– Automobile safety standards
– Air-emission-pollution standards
– Engine-efficiency standards
Governmental Impact
• Federal funding of the highway system. Since 1956, 32,300 miles
of new Interstate highways were built by 1983.
– Federal-Aid Highway Act
– Highway Trust Fund
– Federal funding (TEA-21, SAFETY-LU, 15 billion a year))
Grants are generally made to State and local governments, with a
lesser amount going to Indian tribes, universities, and nonprofit
organizations. These grants are normally used to assist these
entities in the planning, design, and construction of transportation
improvements (e.g., highway, transit, and airport improvements).
• Planned budget (40 billion a year on roads, 15 billion on air, 10
billion on rail, 5 billion on other)
