The history of transport is largely one of technological innovation. Advances in technology have allowed people to travel farther, explore more territory, and expand their influence over larger and larger areas. Even in ancient times, new tools such as foot coverings, skis, and snowshoes lengthened the distances that could be traveled. As new inventions and discoveries were applied to transport problems, travel time decreased while the ability to move more and larger loads increased. Innovation continues as transport researchers are working to find new ways to reduce costs and increase transport efficiency.
International trade was the driving motivator behind advancements in global transportation in the Pre Modern world. "...there was a single global world economy with a worldwide division of labor and multilateral trade from 1500 onward." The sale and transportation of textiles, silver and gold, spices, slaves, and luxury goods throughout Afro-Eurasia and later the New World would see an evolution in overland and sea trade routes and travel.

Road
The first earth tracks were created by humans carrying goods and often followed trails. Tracks would be naturally created at points of high traffic density. As animals were domesticated, horses, oxen and donkeys became an element in track-creation. With the growth of trade, tracks were often flattened or widened to accommodate animal traffic (hollow way or drover's road). Later, the travois, a frame used to drag loads, was developed. Animal-drawn wheeled vehicles were probably developed in the ancient Near East in the 4th or 5th millennium BC and spread to Europe and India in the 4th millennium BC and China in about 1200 BC. The Romans had a significant need for good roads to extend and maintain their empire and developed Roman roads.
In the Industrial Revolution, John Loudon McAdam (1756–1836) designed the first modern highways, using inexpensive paving material of soil and stone aggregate (macadam), and the embanked roads a few feet higher than the surrounding terrain to cause water to drain away from the surface.
With the development of motor transport, starting in 1886 in Germany and in the U.S. in 1908 with the production of Ford's first Model T, there was an increased need for hard-topped roads to reduce washaways, bogging and dust on both urban and rural roads, originally using cobblestones and wooden paving in major western cities and in the early 20th century tar-bound macadam (tarmac) and concrete paving. In 1902, Nottingham's Radcliffe Road became the first tarmac road in the world.
Rail
The history of rail transportation dates back nearly 500 years and includes systems with man or horsepower and rails of wood (or occasionally stone). This was usually for moving coal from the mine down to a river, from where it could continue by boat, with a flanged wheel running on a rail. The use of cast iron plates as rails began in the 1760s, and was followed by systems (plateways) where the flange was part of the rail. However, with the introduction of rolled wrought iron rails, these became obsolete.
The first passenger-carrying public railway was opened by the Swansea and Mumbles Railway at Oyster mouth in 1807, using horse-drawn carriages on existing tramlines. In 1802, Richard Trevithick designed and built the first (unnamed) steam locomotive to run on smooth rails. He was a Cornish engineer and showed off his railway invention in the Welsh mining town of Merthyr Tydfil.
Before actual making the breakthrough for the first railway engine, Trevithick had been facing failures and successes along the route. One of his first successful demonstrations was the "Puffing Devil" steam powered locomotive in 1802 whereas a disaster in Greenwich in 1803 almost sealed the fate of locomotive travel, when four men were killed by an explosion of one of Trevithick's engines. This incident was used as a leverage by his rivals to stop the production of the high-pressure steam engines.
However, Trevithick's "Penydarren locomotive", marked its place in history by becoming the first full scale working railway steam locomotive. A bet between Trevithick's benefactor Samuel Homfray and Richard Crawshay prompted the key demonstration of the locomotive. Homfray had placed a wager of 500 guineas that the locomotive will transport ten tonnes of iron from the Pendydarren Ironworks to the village of Abercynon which was nearly ten miles away.
Trevithick's locomotive completed the journey in just over four hours, ultimately proving the locomotives sturdiness and reliability. However, Trevithick never got the credit he deserved and died a destitute in 1833.
