Transportation planning has conventionally examined mobility from the standpoint of the efficiency of transportation systems, based on trips as units of analysis, overlooking the social needs of excluded groups, such as children. Understanding children’s geographies provides insight into one of the basic social needs of children, intrinsically related to mobility: play. Disadvantages in mobility, along with other social conditions further limit children’s autonomy in their neighbourhood. This chapter proposes the term playability as a concept that intertwines both needs. A case study of neighbourhood analyses the playability needs of children from their perspective and that of the community. Findings suggest that, in a walkable, built environment, issues from criminal activity directly influence children’s playability, even more than automobile presence. Furthermore, community perspective on playability, as mostly limited to structured play in designated spaces and time, separates mobility from play and thus limits opportunities for social inclusion. A change in both, acknowledging children’s need for play and mobility, and their reciprocity, and incorporating measures to improve it, may provide a different framework for transportation and urban planning at the local level, one that seeks greater social inclusion of children.

In recent times, extant literature increasingly underscores the importance of indigenous innovations. This chapter provides an empirical illustration that a collaboration between indigenous knowledge systems and mainstream knowledge systems will not only help overcome the shortcomings in both systems, but also result in more cost-effective and environmentally friendly solutions. The chapter also advocates for public policies that facilitate the development and dissemination of such innovations. Using a case study from the Nigerian context, a framework is provided in this chapter, to illustrate how scientific knowledge can be applied to indigenous innovations to result in the next generation of sustainable, cost-effective and environmentally friendly solutions.

The importance of the adverse impacts of network degradation has stimulated substantial international research interest in transport network reliability, that is, the ability of degraded transport networks to cope with travel demand. Most of the recent research effort has focused on the reliability of urban passenger transport networks, in terms of the probability that the network will deliver a required standard of performance. This situation is characterised by high levels of congestion, a dense road network, and quantifiable probability of degradation of the network. Outside major urban centres, the situation is very different. The main dominant consideration in transport network infrastructure provision is accessibility - linking urban centres, providing regional coverage, and basic levels of accessibility for the non-urban community and economy. The network is sparse, congestion is not a significant issue, and access to essential community services and to markets is the major driving force underlying network development. In this context, the vulnerability of the network is perhaps more important than ‘reliability’. This paper develops the concept of network vulnerability. It begins by reviewing the current state of research into network reliability, then proposes extensions and adaptations to the reliability concepts that are more appropriate for strategic-level multi-modal transport systems. Several alternative definitions for vulnerability are proposed. The paper also discusses the development of algorithmic and visualisation tools that may be used to identify specific ‘weak spots’ in a network, where failure of some part of the transport infrastructure would have the most serious effects on access to specific locations and on overall system performance. Finally, the paper describes potential applications of network vulnerability concepts, and proposes directions for further research.
