CHAPTER 1: INTRODUCTION
Urbanization can be defined as a concentration of people in a geographic area who can support themselves from the city’s economic activities on a fairly permanent basis. The city can be center of industry, exchange, education, government, religious activity, tourism, or involve all these activities. These diverse areas of opportunity attract people from rural area/smaller towns/other cities to the cities where the opportunities’ and life style quality match their aspirations.
Urban areas have many obvious faults insofar as their services to people are concerned. They can be overcrowded, contain large amounts of substandard housing, be polluted (air, noise, environmental), be centers of unemployment, and have vested interest groups. Taxation tends to be high and services less than adequate. However, with all of these faults, urban areas are here to stay. The charge to planners, at all levels, public and private, is to find ways of making these essential elements in our social system work better, more efficiently and thus make our cities better places to live in.
1.1 TRANSPORTATION ENGINEERING:
In the society of today the road network is of great importance. As cities grows so does the needs of transportation and this puts an increased pressure on the infrastructure. Thus it is of great importance to have a reliable and redundant infrastructure for the traffic, to make sure that it works even during bad conditions. There are several different hazards which may have an impact on the road infrastructure such as for example natural catastrophes, accidents or failure of parts of the road network. Since the different infrastructure systems get more and intertwined in the society of today and the society becomes more vulnerable for catastrophes, these hazards might have effects on other infrastructure systems as well. Thus more and more researchers start to look at the risk of
