In your opinion, do you think we use more pavement materials at the superelevation areas?And why?
Do you see a problem driving a superelevation curve in a slow speed (slower than the speed limit)?Links to an external site.
talked about 13 different modes of transportation.
20 years from now, in your
talked about 13 different modes of transportation.
20 years from now, in your opinion, which modes of transportation will disappear, become more popular, or stay the same? Explain why?
those are the 13 different modes of transportation
1) Bicycle. A device propelled via chain, belt or gears, exclusively by human power.
(2) Bus. Any vehicle owned or operated by a publicly owned or operated transit system, or
operated under contract with a publicly owned or operated transit system, and used to
provide to the general public, regularly scheduled transportation for which a fare is charged.
A general public paratransit vehicle is not a transit bus.
(3) Bus Rapid Transit (BRT). A flexible rubber-tired rapid-transit mode that combines stations,
vehicles, services, exclusive running ways, and Intelligent Transportation System elements
into an integrated system with a strong positive identity that evokes a unique image.
(4) Commuter Rail. Traditional rapid and heavy rail passenger service intended to provide travel
options in suburban and urban areas. Corridor lengths are typically shorter than intercity
passenger rail services. Top operating speeds are in the range of 90 to 110 miles per hour.
The tracks may or may not be shared with freight trains and typically are in a separate right
of way.
(5) Conventional Rail. Traditional intercity passenger rail and interregional freight rail. Top
operating speeds are in the range of 60 to 110 miles per hour. The tracks may or may not
be shared by passenger and freight trains and typically run within their own right of way
corridor.
(6) Design Vehicle. The largest vehicle commonly expected on a particular roadway.
Descriptions of these vehicles are found in Index 404.4.
(7) Equestrian. A rider on horseback.
(8) High Speed Rail. A type of intercity and interregional passenger rail service that operates
significantly faster than conventional rail. Top operating speeds are typically 150 to
220 miles per hour. These trains may be powered by overhead high voltage lines or
technologies such as Maglev. The tracks are grade separated within a separate controlled
access right of way and may or may not be shared with freight trains.
(9) Light Rail. A form of urban transit that uses rail cars on fixed rails in a right of way that may
or may not be grade separated. Motorized vehicles and bicycles may share the same
transportation corridor. These railcars are typically electrically driven with power supplied
from an overhead line rather than an electrified third rail. Top operating speeds are typically
60 miles per hour.

(10)Pedestrian. A person who is afoot or who is using any of the following: (a) a means of
conveyance propelled by human power other than a bicycle, or (b) an electric personal
assistive mobility device. Includes a person who is operating a self-propelled wheelchair,
motorized tricycle, or motorized quadricycle and, by reason of physical disability, is
otherwise unable to move about as a pedestrian as specified in part (a) above.
(11)Street Car, Trams or Trolley. A passenger rail vehicle which runs on tracks along public
urban streets and also sometimes on separate rights of way. It may also run between cities
and/or towns, and/or partially grade separated structures.
(12)Transit. Includes light rail; commuter rail; motorbus; street car, tram, trolley bus; BRT;
automated guideway; and demand responsive vehicles. The most common application is
for motorbus transit. See Index 404.4 for a description of the design vehicle as related to
buses.
(13)Vehicle. A device to move, propel or draw a person upon a highway, except a device on
rails or propelled exclusively by human power. This definition, abstracted from the CVC, is
intended to refer to motor vehicles, excluding those devices necessary to provide mobility to
persons with disabilities
