Jordan has experienced in the last decade a continuous increase in the number of accidents, which has resulted in a high number of fatalities and injuries. There are many reasons behind this critical traffic situation in Jordan, Some of these reasons are the lack of well-defined land use policies that relate the development pattern and density to transportation, the unsafe and unreliable transportation system, and the concentration of jobs and governmental services in the center of the capital and governorates.
This paper studies the relationship between the gross population density and the total number of accidents for the different governorates in Jordan. It was concluded that the people of the governorates with high gross population density are involved in more accidents with low severity indices than those of the governorates with less gross population density. On the other hand, the people of the governorates with less gross population densities are involved with fewer accidents but with high severity indices. It was also found that buses are involved in more accidents than their share of total traffic. This paper recommended, among other things, a development of land use policy to shape the future transportation system in Jordan and consequently set the goals and objectives to reduce the number of accidents and their severity.
