Urban Land Use and Transport Interaction in Ibadan: Implications for Sustainable City Planning

The interaction between urban land use patterns and transport demand is a foundational concern in sustainable city planning, shaping the volume, direction, and mode of travel within urban areas. This study analyses urban land use and transport interactions in Ibadan, examining whether current planning frameworks adequately account for transport demand implications. A mixed methods design combining travel demand modelling with qualitative planning document analysis and interviews with 30 urban planners is employed. Trip generation and distribution data from a household travel survey of 600 households across five zones are used to construct a four-step transport demand model, calibrated against observed traffic count data. Model simulations show that the current dispersed, low-density land use pattern of Ibadan generates per capita vehicle kilometres travelled approximately 35 percent higher than a compact, mixed-use development scenario. Commercial zones concentrated in the city centre generate significant reverse peak traffic flows, indicating a mismatch between residential and employment location patterns. The study finds that the Ibadan Urban and Regional Planning Authority lacks explicit transport-land use integration tools in its development control procedures, a gap identified in no prior study for this city. Recommendations include the introduction of transport impact assessments for all major development applications, transit-oriented development incentives along BRT corridors, and the adoption of a transport-informed land use master plan for the Ibadan-Oyo metropolitan area.
