The problem of transportation management has many variables but its solution must be guided by societal needs based on expected benefits and ways of achieving them. Thus transport management can be immensely enhanced and simplified by the use of a geospatial information system. Lagos, the commercial center of Nigeria, has been suffering from traffic congestion for decades. The loss suffered as a result of this congestion cannot be easily quantified economically and socially. This article presents empirical solutions to transportation problems in the Lagos Metropolis using the "Bottom-Top" approach, from "Transaction-Based" at local government level to "Multimodal" at the metropolitan level. The Stochastic User Utility Model was adopted to estimate the appropriate representation of human heterogeneity, flexibility and variability on mode choice relative to route travel times. The use of Assisted GPS Cameras provides some level of intelligence on the transportation routes. Results obtained include a travel demand survey (household-based) within a Traffic Zone and Sampled Trip Production/Trip Attraction Analysis based on Modes of Transportation. Geospatial Analysis carried out included Proposed Multimodal Transportation Routes with Transfer Points (TPs) and Incident Facility Management analysis. The synergy of Multimodal and Intelligent Transportation System (MITS) to obtain an integrated Multimodal Transaction-Based Intelligent Transportation System (MTBITS) will enhance efficient transportation systems for the Lagos Metropolis.
