Q
  • This transportation system includes commercial airlines, airfreight carriers, and general aviation (private aircraft).
  • High line-haul speed; accessibility is limited; capacities of individual aircraft are moderate; capital and operating costs are both high but high productivity results in moderate costs per passenger carried.
  • Environmental impacts are significant, especially the noise impacts of commercial aviation.

Q
  • This system provides moderate speeds and levels of accessibility, but traditional operating practices, which involve relatively short hauls between rail yards, where trains are broken up and reassembled, lead to high and unreliable door-to-door travel time.
  • Capital costs of locomotives and railcars, and maintenance costs for track are also relatively high.
  • Environmental impacts are comparatively low.

Q
  • This domestic transportation system consists of coastwise ocean shipping and barge lines operating on inland waterways.
  • Provides low speed and relatively low accessibility, but extremely high capacities.
  • Capital cost of vessels is high.
  • Environmental impacts are relatively low but water pollution from routine discharges of oil and other pollutants, as well as from major oil spills involving tankers, is a significant problem.

19
Q

Scope of Highway Engineering

A
  • Development, planning, and location
  • Highway design, geometric, and structure
  • Traffic performance and its control
  • Materials, construction, and maintenance
  • Economic, finance, and administration
20
Q
  • Roads are used by various types of road vehicles, like passenger cars, buses, trucks, pedal cycle, and animal drawn vehicle.
  • It requires a relatively small investment for the government.
  • It offers a complete freedom to road users to transfer the vehicle from one lane to another and from one road to another according to need and convenience.
  • Speed and movement is directly related with the severity of accident.
  • Road transport is the only means of transport that offers itself to the whole community alike.
A

Characteristics of Road Transport

21
Q

exists wherever demand exceeds the capacity of the transportation system.

A

Traffic congestion

22
Q

is a condition on transport networks that occurs as use increases, and is characterized by slower speeds, longer trip times, and increased vehicular queuing.

A

Traffic congestion

23
Q

  • Improving safety
  • Providing equal access
  • Protecting the environment
A

Performance of the transportation system

24
Q

  • Securing financial resources
  • Developing adequate institutional arrangements
A

Performance of the transportation engineering profession, economic and political system

25
Q
  • The usual response to congestion was to build more ________
  • This approach was always limited by the availability of ________.
  • Political support for major expansions of the urban highway system is now lacking due to the potential ________________________.
A

capacity

funding

potential environmental impacts

26
Q

Since ____, there have been repeated calls to shift from private automobiles to urban passenger transportation because of the environmental consequences and the cost of expanding the system.

A

1960

27
Q

is a system of surcharging users of public goods that are subject to congestion through excess demand such as higher peak charges for use of bus services, metros, railways, and road pricing to reduce traffic congestion.

A

Congestion pricing

28
Q
  • A second major challenge is the continued improvement of ___________.
  • Traffic accidents are of concern for all modes of transportation, but are perhaps most visible in highways and commercial air.

*____________ is continuing challenge for the transportation engineering profession because of public expectations that safety will continue to improve.

  • The focus of agencies involved with transportation safety are improvement of safety of vehicles, traffic safety, safety research and development, and collection of accident data.
  • These agencies investigates selected accidents involving all transportation modes, identifies safety problems, an serves as an advocate for transportation safety concerns.
A

Traffic Safety

    Environmental Protection
A

Air pollution

40
Q

A

These goals are to be achieved through:

43
Q
  • Securing adequate financial resources is another perennial challenge, both for:
    • Public agencies, providing transportation facilities
    • Private-sector firms, providing transportation services.
  • The most common forms of user charges:
    • Fuel taxes, which have been applied as a fixed charge per gallon/liter of fuel
      sold.
    • Direct fares or tolls.
A

Funding

44
Q
  • New arrangements have come about as a response to perceived deficiencies in the existing system. Often they have been imposed by outside agencies and in many cases they have been resisted by established institutions.
