Beyond the known: Walking accessibility twist to new cities.

While research on new cities is emerging across African cities, focusing on housing, infrastructure, and service provision, little is known about walking accessibility for residents within and outside these new cities. Using the national capital of Ghana as a case study, the purpose of this paper is twofold: (a) it measures walking accessibility within and outside new cities in Accra; and (b) it compares walking accessibility to urban amenities between residents in and outside new cities. Publicly available data on the location and distribution of various urban amenities in Accra were obtained, and accumulated distance and spatial autocorrelation statistics were used. Our findings demonstrate that while at the metropolitan level, less than 50% of residents have walking accessibility to the nearest parks, schools, and new job opportunities within 15 min' walk, those in new cities were significantly disadvantaged in terms of walking accessibility to parks, job opportunities, schools, and public transport stops compared to residents outside. The findings show that the location of new cities does not consider walking accessibility in Accra. This finding underscores the uncoordinated and splintering phenomenon that epitomizes the spatial location of new cities and their contribution to unsustainable urban forms. Given that new cities are rapidly emerging in African cities, we recommend a more coordinated and balanced provision of urban amenities within walking distance in new cities and peripheral areas of African cities to generate efficient, livable, and sustainable urban forms. • This paper examines walking accessibility for residents within and outside new cities. • Walking accessibility to six work and non-work activities is computed. • Findings indicate new cities are disadvantaged in terms of walking accessibility to amenities. • It recommends a more coordinated and balanced provision of amenities within walking distance in new cities.
