Problem of trqffic congestion is common in most big cities of the world.Drivers of privately owned vehicles and passengers may experience substantially loss of time while in traffic jam. Also, solutions to causes of this menace are well documented in the literature. In spite of the vast studies and applied measures toreduce these jams, the problem seems to be growing stronger on daily basis. One ofthe o~jectives of this study is to examine (l the intensity of traffic congestions are similar along the routes, and on d(fJerent days of the 'week within the ci~y of Lagos.The paper also examines the traffic pattern along ten selected routes within five metropolitan areas in the state. The study shows that 57% of the commuters and motorists in the study area do spend an average of 30 to 60 minutes in congestedtraffic. Three peak periods of traffic congestion were recognized. Indiscriminateparking, road side trading, flooding, existence o.fpot-holes on these roads, vehiclesbreaking down and absence o.f traffic light at some road intersections are some ofthe identified major causes of traffic congestions. Mondays were recognized as the most congested day by 57% of motorists and commuters interviewed. The analysis o.f variance result shows insign(ficant variation in traffic congestion among the fivelocal government areas. However, the observed spatial and temporal pattern o.l vehicular traffic congestion enabled us to suggest possible measures for the reduction of traffic congestion within the metropolis.
