1.1 Background 1.1.1 Roads and Civilization

1.1.1 Roads and Civilization

The wheel was invented in 5000 BC years. This made necessary the construction of special hard

surfaces of roads. Ancient roads were built to suit the old mode of

transportation (horses, donkeys and carts). Motor vehicles used these roads and in many cases they were not very suitable.

Roads improve communication and hence civilisation. The prosperity of a nation is bound up with the state of its

roads.

History of Car

In 1769, the very first self-propelled road vehicle was a military tractor invented by French engineer and mechanic, Nicolas Joseph Cugnot.

Cugnot used a steam engine to power his vehicle,

Speed (2.5 mile/h) The vehicle had to stop every ten to fifteen minutes to build up steam

power.

1.1 Background1.1 Background

In 1771, Cugnot drove one of his road vehicles into a stone wall, making Cugnot the first person to get into a motor vehicle accident.

This was the beginning of bad luck for the inventor.

After one of Cugnot's patrons died and the other was injured, the money for Cugnot's road vehicle experiments ended.

Between 1832 and 1839 Robert Anderson of Scotland invented the first electric car. Electric cars used rechargeable batteries that powered a small

electric motor.

The vehicles were heavy, slow, expensive, and needed to stop for recharging
