Abstract
This thesis analyses the bottlenecks associated with the transport system infrastructure that currently exists in the city of Lagos, south-west Nigeria using GIS approach combined with graph and probabilistic methods while taking into consideration the different modes of transports that are currently defined and allowed in Lagos. Results of the analysis indicate the size of the problem, especially in more pronounced areas, and the potential transport solutions for government to utilize which may be made within the current budget of Lagos. The major traffic corridors were identified and classified according to vehicular volumes in addition to using a survey of travel modes for Lagos in the analyses which lead to the proposal of walking and biking as an alternative mode of transport in heavily congested corridors to reduce traffic. The data for the analysis was gathered using open sources such as Google maps, open street maps, Google traffic, relevant authorities in Lagos, while some secondary data were obtained from papers on Lagos traffic. Part of the data was also obtained through web health/transport monitoring application. The analysis also demonstrates flow capacity of each region in Lagos with relative transport infrastructure which serves for people transportation. The results of web survey were implemented to make a correct simulation of transit flows. Six interactions were made. Flow volume data and congestion analysis were also developed. Congestion graph was created and used for each community’s analysis of which six main communities were identified and include Ikeja, Lagos city, Eti Osa, Ikorodu, Alimosho, and western territory after Festac town. The results of analyses show that these territories can be connected by bicycle networks through least congested areas called green areas (zones) without the need for cars. Walking solutions are proposed for distances less than 6km within city blocks.Description
