While the largest cities are the most congested, congestion occurs—and has grown—in cities of every size Congestion extends to more time of the day, more roads, affects more of the travel, and creates more extra travel time than in the past. It has become more volatile as well in cities of developing world. Rising population, rapid economic growth and increasing employment without a corresponding growth in the supply of public transport, responsible largely for major urban traffic issues in most cities of developing economy. Thus, this paper intends to examine in holistic contexts the traffic congestion problem in developing countries with case study of Lagos state, Nigeria: causes, consequences, costs, and what can be done to improve alarming rate of Traffic congestion.

For instance, Of the 15 largest mega-cities identified by United Nations, only four are located in highly industrialized countries: Tokyo, New York, Los Angeles, and Osaka-Kobe-Kyoto. The overwhelming majority of mega-cities is located in developing countries, and includes such gigantic conurbations as São Paulo (18.8 million inhabitants in 2007), Delhi (15.9 million), and Manila (11.1 million).Also, by 2015 Sao Paulo (20.2), Delhi (20.0), Manila (12.8 million), Cairo (13.5 million) and Lagos (12.8 million inhabitants ).However, by 2025 Delhi will have 22.5 million , Sao Paulo (21.4) Lagos 16.8 , Cairo 15.8 and manila 15.6 million inhabitant .(see Table 1.0). It however paradoxical that Vehicle ownership is growing geometrically without corresponding land use planning and sustainable transportation planning strategies whilst, something urgent measures must be done to redress the alarming rate of Traffic congestion.
