    Activity Participation and Perceptions on Informal Public Transport and Bus Rapid Transit in Dar es Salaam
    (SAGE, 2020-09-10) Joseph, Lucy; Neven, An; Marten, Karel; Kweka, Opportuna; Wets, Geert; Janssens, Davy
    This paper seeks to understand participation in out-of-home activities by inhabitants in Dar es Salaam, and their perceptions toward informal public transport (IPT) and bus rapid transit (BRT) in supporting these activities. Without fixed schedules, IPT (e.g., minibuses, motorcycles, and tricycles) is used as a means of transport for different trips. However, IPT is burdened by poor roads, traffic congestion, and high transport demand. Many developing cities are seeking to replace IPT with formal BRT lines. However, little is known in relation to the ability of IPT and BRT to support out-of-home activity participation of the inhabitants. This paper reports on a study in Dar es Salaam exploring the relative contribution of each type of service. The study took place before the opening of BRT, and encompasses focus group discussions, participatory geographical information systems, and questionnaires carried out in two study zones: one close to a BRT corridor and the other in a peri-urban location. The findings show that IPT was used to support participation in daily activities like work, education, shopping, and social matters; and was perceived to be flexible in providing access to both high and low density unplanned settlements. The BRT was viewed to benefit specific groups of people, especially individuals working in permanent offices in and around the city center, particularly professional workers. This paper sheds light on how the two systems were perceived by the local people and can inform policy makers about possible improvements in public transport systems to support activity participation of their inhabitants

    Exploring changes in mobility experiences and perceptions after implementation of the bus rapid transit system in Dar es Salaam
    (Elsevier BV, 2021-06) Joseph, Lucy; Neven, An; Marten, Karel; Kweka, Opportuna; Wets, Geert; Janssens, Davy
    The use of Informal Public Transport (IPT) in Dar es Salaam, Tanzania, has been associated with mobility difficulties, i.e. traffic congestion, unscheduled service and lack of safety and security. The introduction of the Bus Rapid Transit (BRT) system was therefore considered as a powerful intervention for these mobility difficulties. In May 2016, the BRT started operating with exclusive bus lanes and a clear schedule to offer a qualitative, accessible and affordable system. This paper explores changes in travel experiences and perceptions of individuals (local inhabitants) regarding IPT and BRT use in meeting mobility demands before and after implementation of the BRT. Focus group discussions and short questionnaires were conducted before and after BRT to explore changes in mobility experiences among different individuals. Results show that in both periods, the demand for IPT use remained dominant, driven by a low fare, connectivity within a neighbourhood and outside the major road, flexibility and the possibility to commute with goods. The use of BRT was mainly attributed by relief in traffic congestion (when only considering in-bus time) and a lack of options along the corridor. Surprisingly, BRT users also experienced several mobility difficulties after implementation: long waiting time, overcrowding (in-bus and stations), and difficulties to commute with goods, and a lack of safety and security. Peri-urban individuals continued to experience more travel difficulties with both transport systems than individuals in areas adjacent to the BRT because of limited connectivity, congestion and unpaved local roads. For low-income individuals, the BRT was considered as another burden for their livelihoods (higher financial cost) rather than it was expected as a solution towards a high quality, accessible and affordable system. There is a need to integrate public transport with supportive improved local roads to serve multiple destinations

    Measuring Individuals' travel behaviour by use of a GPS-based smartphone application in Dar es Salaam, Tanzania
    (Elsevier, 2020-10) Joseph, Lucy; Neven, An; Marten, Karel; Kweka, Opportuna; Wets, Geert; Janssens, Davy
    A range of mega-cities in the Global South have started to invest in Bus Rapid Transit (BRT) systems, as a complement or replacement for informal paratransit services, in an effort to improve the mobility and accessibility in the city. Yet, few studies have tried to analyse the impact of such systems on the mobility patterns of cities' residents, in part because traditional travel diary surveys are often too expensive to conduct and unsuitable to capture spatial mobility patterns in fast growing cities with a high level of informality in spatial development. In this study, we analyse the applicability of a new method of data collection, i.e. a GPS-based smartphone application, to capture individuals travel behaviour in fast growing mega-cities in the Global South. Our case study is the city of Dar es Salaam (DES) in Tanzania, where the first BRT line is currently being implemented. In our study, the GPS-based app was used by individuals in DES to record distances, departure times and destinations of their trips. Socio-demographic data of respondents were recorded in short questionnaires. The spatial distribution of the trip patterns shows the mobility demand in both high and less connected areas. The results reveal a variation in departure times, travel destinations and trip distances that are one the one hand spatially limited within neighbourhoods and away from the planned BRT, and on the other hand along major roads connecting to the Central Business District (CBD). The short average distances of the trips (<3 km) reveal the characteristics of paratransit modes. The GPS-based smartphone application provides an opportunity to policy makers to engage deeply with the spatial reality of local communities, as a basis for transport investments and policy improvements as steps towards an integrated public transport system.
