This study uncovers the pluralities and often overlooked vistages of accessibility in shaping the travel dynamics of suburban areas, revealing how these zones are essential to urban transformation and livability in developing economies. Contemporary planning best practices have endorsed the connections between transportation and land use accessibility as a fundamental paradigm for creating sustainable and functional cities. Yet, while much has been speculated about these relationships, the intricate dynamics of accessibility linkages from the sister neighbors of central cities (the so-called inner suburbs) to urban cores remains cosmetically documented. This gap has left much of the potential for inner suburban accessibility untapped, limiting its impact on city planning and policy direction especially in fast-developing regions. Focusing on one of Africa’s fastest-growing metropolises, this study captures the ulti-dimensional nature of accessibility levels in shaping urban development factors like land value capture, traffic pattern dynamics, and air quality outcomes. Employing institutional surveys and a cross-sectional design, the study finds that the ease of destination accessibility and the introduction of new transportation infrastructure are key determinants of land value differentials in central business district (CBD) adjacent areas. We also found that peak travel times have exacerbated cumulative trip durations across major travel mode choices except for walking. While congestion levels have reduced inter-zonal trips within these inner suburbs, vehicules navigating suburban corridors are experiencing a disproportionate surge in operating costs and generating comparatively higher greenhouse gas emissions within a 1.5-km radius of the CBD. The study offers valuable recommendations beneficial for regions experiencing similar conundrums. We suggest the creation of diffused secondary centers-otherwise known as polycentric development-along major activity corridors emanating from inner suburbs to reduce trip lengths and optimize commuter travel efficiency. The study further discusses opportunities for fostering suburban accessibility and supporting a more sustainable urban transportation future.
