2.0 BACKGROUND

2.1Early Development of Cars and Trucks:

More than 100 years ago the first cars and trucks carried occupants and goods along unimproved or dirt roads. As cars and trucks evolved, so did roads. First stone roads, brick roads in urban areas and finally asphalt and concrete roads. From the one lane roads of the early 1900's roadways developed into highways and superhighways as cars were designed to reach higher speeds.
