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.

Establishment of an empirical Geoid Model for a small geographic area: a case study of Port Harcourt, Nigeria / J. Olaleye in SaLIS Surveying and land information science, vol 70 n° 1 (Spring 2010)

Consequently, an empirical method is often adopted for a small geographic area. This approach is especially useful because of its simplicity, accessibility to local surveyors, and its adequacy for many applications involving the conversion of World Geodetic System 1984 (WGS 84) GPS heights to a local height reference system based on the Mean Sea Level (MSL). This paper details the procedures and processes used to establish, validate, and consider the statistical significance of a predictive geoid model for a small geographic area. The model is based on data acquired within the central areas of the Port Harcourt metropolis in southern Nigeria. The MSL benchmark of the Nigerian Ports Authority (NPA) in Port Harcourt, which was established during the colonial administration, served as the reference datum.
