Abstract

Purpose

Sub-Saharan African cities suffer from poor quality transport options, excessive congestion and pollution. The informal transport sector contributes to these problems, but also represents part of the solution. This chapter reflects upon research undertaken to better understand the nature of these services, in the hope of providing insights into possible remediation.

Design/methodology/approach

Three case cities were studied: Cape Town; Dar es Salaam; and Nairobi. Each was examined by resident universities with respect to the quantity and quality of paratransit services provided, user satisfaction, business models and industry governance.

Findings

Each city has differences, but there are recurring themes. All are experiencing population growth and increased motorization, which steadily deteriorates operating environments. Law enforcement capability is limited and sometimes impeded by corruption. Operating enterprises tend to be fragmented. Financial resources are typically limited such that vehicle maintenance and replacement suffers. The safety and quality of service for passengers are therefore often poor. The prevalence of paratransit services is, however, such that any strategy to reform public transport systems needs to consider a role for them within a scheduled-paratransit hybrid network. Numerous challenges will need to be overcome for successful integration, but significant improvements to service quality can be made in the near- to medium-term through supporting interventions in business development, operating environment, vehicle fleets and operations.

Research limitations/implications

Extension of the research programme could yield some significant improvements to operations and financial sustainability, through the piloting of innovative, lower cost technologies based on smartphone and other ICT technologies.

Originality/value

The chapter reveals that significant improvements to service quality can be made in the near- to medium-term through supporting interventions in business development, operating environment, vehicle fleets and operations.

Abstract

Purpose – Bicycle riding provides a sustainable and affordable solution to many of the significant problems associated with motorised transport and physical inactivity. The provision of infrastructure plays an important role in encouraging people to begin and subsequently continue to ride bicycles and to do so safely.

Methodology – This chapter describes different types of on- and off-road infrastructure and reviews studies of their effects on rider numbers and safety. In addition, it looks at the roles that end-of-trip facilities and bikeshare programs can play in contributing to bicycle use and general transport sustainability.

Findings – Infrastructure characteristics can influence both perceived and objective levels of safety. It is important to identify and avoid treatments that increase perceived safety but are actually less safe. The type of infrastructure needed or desired differs between current and potential riders and according to trip purpose. Well-designed marked bicycle lanes on roads can reduce crash rates. Safety at intersections can be improved by: advanced green lights for cyclists, short cuts for right-hand turns, brightly coloured bicycle paths and advanced waiting positions for cyclists. Off-road facilities are generally safer, but intersections with roads must be carefully treated. Shared paths and footpaths are risky for older pedestrians (and older cyclists).

Implications – In many countries the provision of more infrastructure that increases the perceived safety of riding is needed to encourage cycling, particularly transport cycling and cycling by women.

Abstract

Purpose – Urban and suburban arterials carry a large share of urban traffic and contend with a relatively large proportion of transport network crashes. Road crashes and their consequent societal costs diminish the sustainability of transportation systems, highlighting the need to identify road safety problems and their corresponding solutions. This chapter briefly outlines problems and solutions associated with crash risk on urban and suburban arterials. In addition, this chapter studies and discusses several safety countermeasures – ranging from local treatments to integral frameworks – and their effectiveness on improving traffic safety of urban and suburban arterials.

Approach – Crash occurrence on urban and suburban arterials is affected by numerous contributing factors. This chapter pays attention primarily to the effects of traffic characteristics and road design features. In this regard, several pertinent variables which have been extensively examined in the literature are reviewed and their contributions to the safety of urban and suburban arterials are discussed.

Findings – A review of the literature identifies a number of variables as influential factors of crashes on urban and suburban arterials. Although the associations of some variables (e.g., traffic volume) are consistent with expectations, others (e.g., lane width and speed) show mixed and sometimes counterintuitive results. These findings signify that additional research is needed to reveal the correct functional form and magnitude of these relationships.

Practical implications – The results show that while the general direction and magnitude of effects of some engineering and management-related treatments are known, additional research is needed to consolidate the impact and effectiveness of integrated approaches.
