Transport in Egypt is centered in Cairo and largely follows the pattern of settlement along the Nile. The Ministry of Transportation and other government bodies are responsible for transportation in Egypt, whether by sea, river, land or air. With regards to driving, Egypt has one of the highest incidents of road fatalities, per miles driven, in the world. The badly maintained road network has expanded rapidly to over 21,000 miles, covering the Nile Valley and Nile Delta, Mediterranean and Red Sea coasts, the Sinai and the Western oasis. Traffic rules are routinely ignored by impatient drivers.
