Land Transportation
Innovative and efficient transportation from one place to another has been
the inspiration for inventions and new technologies for hundreds of years.
Land transportation is used for the movement of people, animals, and goods from one location
to another. For centuries, people have
relied on land transportation to trade goods, to travel from place to place and to
stay connected with one another.
Transportation is important because it allows trade between people, which helps promote interstate
commerce and globalization. Walking and swimming were the first ways humans traveled across land. The
domestication of animals introduced a new way to transport goods, allowing heavier loads to be hauled, and
gave humans the ability to ride the animals for quicker and for longer distances.
Inventions such as the wheel and sled soon helped make animal
transport more efficient as goods could be
transported with their use. Water transport, including rowed and sailed vessels, dates
back to the times of the ancient caveman, and was the easiest way to
transport large amounts of goods over large
distances before the Industrial Revolution.
Types of Land transportationTransportation can be broken up into three main
categories: vehicles, infrastructure, and operations. Vehicles are any machine capable of carrying people and
objects from one place to another.
The success of the Industrial Revolution depended on the ability to transport raw materials and finished goods over long distances. There were three main types of transportation that increased during the
Industrial Revolution: waterways, roads, and railroads.
InfrastructureInfrastructure describes the highways, rails, refueling
stations, and other structures necessary to support a vehicle’s
movement.
Operations include the day-to-day management and long term planning that make transportation. These operations can include the employees who run or manage public transportation each day or those responsible for timing and planning stop lights at intersections.
Operations
The investment in public transportation options like buses and subways vary from country to country. Often, people who live in rural communities with
smaller populations do not have access to the
commuter rail services and other forms of public
transportation that help individuals reach and move
within bigger cities.
Currently, more than three-fourths of the world’s vehicles rely on fossil fuels, or naturally occurring fuels formed by the
decomposition of organisms over time. Scientists think the 800
billion barrels of oil that are left under ground will only last about fifteen more years if fossil fuels continue to be used at the same rate. Because of this, the future
of land transportation will heavily depend on how
alternative energy sources can be utilized.
Alternative Energy
The alternative energy needed for transportation will
increasingly come from electricity, hydrogen and
biofuels and naturally occurring elements like wind
and solar power. Land transportation will also be
shaped by the availability of more sustainable vehicles
that are lighter, powered by smaller engines or alternative
means of propulsion.
The introduction of hybrid vehicles, which
are vehicles that contain both an electric motor and a gasoline
engine, are also options becoming popular
means of transportation.
Typically, the act of braking is used to help recharge the battery of
the electric motor.
. Another type of vehicle used more in the future will be the electric vehicle or EV. The EV is a vehicle, which uses one or more electric or traction motors for propulsion. In 1900, 34% of the cars in Boston,
Chicago, and New York were electric and almost half had steam engines. Today, less than 1% of vehicles on American roads are
electric.
However, there is significant concern about the energy efficiency of hybrid vehicles. Recent studies indicate that the
energy needed to produce and charge an electric
vehicle is more environmentally damaging than the use of traditional
internal combustion engines. As such, a split
may emerge between short-range urban cars and
long-range highway vehicles.
Since the creation of the first car, automobile ownership has allowed humans to commute to better jobs, travel to exciting
places, impress others, and cover distances more quickly than ever before. In 2002, there were 590 million
automobiles in the world. By 2050 the United Nations predicts there will be more than 9 billion people resulting in nearly 4 billion vehicles on the roads. With more vehicles on
the road than ever before, the freedom of mobility once afforded to those who owned cars is quickly
deteriorating.
First Cycle SuperhighwayEach year, more than 4.2 billion hours
are lost in traffic congestion, resulting in the waste of 2.8 billion gallons of fuel. Because transportation in and around
cities is becoming more time consuming and environmentally damaging,
governments are investing in better infrastructure to the use of public
transportation and cycling. The world’s first “cycle superhighway” in Denmark is made up of 11 miles of smoothly paved paths, complete with air pumps at each
mile.
As an alternative to single person rides, services that promote carpooling or ridesharing are becoming increasingly popular. Zipcar, a membership-based car sharing company, helps provide automobile reservations to members, with a fleet of self-service vehicles.
At the same time new websites and apps are trying to help
individuals connect and share rides. In efforts to decrease traffic congestion, control fuel usage and
create a greener environment, some governments have turned to
stricter regulations on single-occupant drives, and vehicle fuel
emissions.
Autonomous vehicles, also known as robot cars or
driverless cars, are being developed around the world.
Driverless cars will give people the freedom to take their eyes off the road to eat, read, talk on the phone and more. With
vehicle-to-vehicle communication and vehicle-to-vehicle infrastructure cars are
able to monitor their environments and “talk” to one another as they travel.
These driverless vehicles are a safe, stable option for those
who are unable to drive safely.
In 2011, Nevada was the first state in the U.S. to legalize driverless vehicles on their
roads. Smart cars will also have the ability to form road trains,
which is also known as "platooning" where vehicles form a line one after another and rely on the first, or front,
car to navigate.
In Australia road trains are already replacing railways as a means of
transporting goods on routes throughout the center of the country. Soon, the visual elements people rely
on to drive like speedometers, steering wheels, and rear-view-mirrors may be eliminated from cars entirely
since they will not be needed. Systems are also envisioned for
driverless cars that are guided by magnetic rails and other forms of
enhanced highways. By 2040 experts predict 75% of the cars on the road may be driverless. These cars could reduce car crashes by as much as
14%.
People continue to be fascinated with using new, innovative ideas for vehicles and alternative
transportation methods. Each year car designs and inventions make people want to buy the fastest, sleekest and most unique vehicles on the road.
However, more and more experts insist that there is a need to completely rethink how and why people use transportation to develop and inspire completely new
ways travel by land.
As society becomes increasingly mobile-driven, even food vendors and libraries have transitioned to
wheels. Where will the future of transportation take us? What are innovative ideas already being tested?
What is the future of Land Transportation?
Are hybrids and fuel-efficient vehicles the
answer for the future of transportation or will
regional air travel be a cheaper, quicker, safer,
and more environmentally friendly
alternative to in the years to come?
