The impact of road access management on traffic and safety operations in emerging urban centres:critical analysis

Abstract

Urbanisation poses multifaceted challenges, including traffic congestion, environmental issues, and deteriorating transportation infrastructure. The study examines the ramifications of the evolving management of road access on traffic and safety operations within Ongwediva town (Namibia), an emerging urban centre. The existence of informal access points along the roadway, influenced by varied land use developments, presents impediments to the safe conduct of traffic operations. The suboptimal performance of the transportation network is further exacerbated by outdated transportation systems, resulting in issues such as prolonged travel times and unregulated access control. Moreover, a discernible gap exists in the literature, on the interplay between access management techniques and urban traffic operations in emerging urban centres in Sub-Saharan Africa. The research gathered data on traffic characteristics and road access in Ongwediva, mapping them for a thorough analysis. The subsequent critical discussion drew upon existing empirical studies regarding the influence of access management on traffic safety and operations. The results offer valuable insights for traffic planners, emphasizing the importance of effective access management and adherence to recommended access and intersection spacing as vital components in optimizing urban traffic operations and road networks. This discussion also underscores the need for additional examination and contextualization in developing countries concerning the interplay of all facets of access management and the transport system.
