On the Track of Road Evolution

Man’s tendency to move began millennia ago, satisfying a basic need for food, shelter, clothing or social interaction. The uncertain path of road construction through the centuries is set forth by the primitive and everlasting need for mobility, trade and communication. In the era of engineering, and mostly technological boost, highways of the fourth generation ensure safe, fast and easy driving. It is difficult to discern deficiencies or drawbacks in the layout of a motorway of the fourth generation. However, weak points still exist.

The Japanese Experience with Highway Development

Japan now has one of the world’s most highly developed multimodal transport systems. This was only made possible by successfully building an extensive highway network in a short period of time. The two remarkable aspects of this network have been the scale and layout, which were based not only on traffic volume forecasts but also on the principle of equal access. The Japan Highway Public Corporation (JHPC) was instituted in 1956 to oversee the development and expansion of the highway network.
