From Chaos to Order: Designing for Multifunctional Efficiency in Intracity Bus Termini in Nairobi

Abstract

Nairobi’s intra-city bus termini have evolved from simple transit nodes into multifunctional urban spaces accommodating transport, commercial, and social activities. However, this growth has been largely unplanned, resulting in congestion, pedestrian-vehicular conflicts, underutilized off-peak spaces, and declining user comfort. With 47% of Kenyans relying on public transport each day, the spatial efficiency and comfort of these hubs are increasingly critical. Yet their uncoordinated evolution has overwhelmed existing infrastructure, producing congestion, spatial disorder, and user discomfort, particularly at legacy facilities such as Kencom Bus Stage and Railways Bus Station located in Nairobi’s CBD, where dense pedestrian-vehicular convergence compromises accessibility. This study investigates the spatial and operational challenges of five key termini—Kencom Stage, Central Bus Station, Ngara Bus Terminus, Muthurwa Terminus, and Railways Bus Station. Using mixed-methods, comparative case-study design, the study concentrated on Ngara and Central Bus Station. A total of 150 field respondents (commuters, vendors, and PSV personnel) were surveyed, which was augmented by systematic observations, semi-structured interviews, and spatial audits. Quantitative data were processed in R 4.3 and Python 3.11 to generate descriptive statistics and χ 2 tests, while qualitative materials were thematically coded in NVivo 14. GIS-based mapping and AutoCAD overlays visualized functional conflicts and underused areas. Findings reveal a persistent design bias toward vehicular flow: peak-hour pedestrian density exceeded the comfort threshold of 1.8 persons m − 2 , and 73% of passengers alongside 62% of vendors reported frequent conflicts, noise, overflow queues, and inadequate weather protection. At the same time, 30% of off-peak terminal floor area was unused, which underscored poor use of space. The research recommends interventions include multimodal integration that privileges human-scale movement, context-specific zoning of complementary uses, modular and inclusive architectural solutions. The study concludes that reimagining Nairobi’s bus termini as inclusive, human-centered, and economically vibrant mobility hubs can simultaneously improve transport efficiency, enhance commuter experiences, and support informal economic activities.
