Modeling Commuter Preferences for the Proposed Bus Rapid Transit in Dar-es-Salaam

Abstract

The paper analyzes individual commuter preferences towards the proposed bus rapid transit (BRT)

Who could benefit from a bus rapid transit system in cities from developing countries? A case study from Kampala, Uganda

“…With plans for a BRT system in Kampala, the Kampala Capital City Authority should be able to meet its first and often stated as the most important (Nkurunziza et al, 2012) goal: the results indicate that for the majority of respondents, using BRT at projected speed can reduce the average travel time by 50%. While average speed along Jinja road is reported at 20 km/h (ITP, 2010) and research results reveal that actual speed is below even this, a BRT proved in other case studies to be able to obtain speeds up to 25 km/h.…”

Spatial variation of transit service quality preferences in Dar-es-Salaam

“…The 'Without DART' scenario served as a base (daladala) scenario during analysis. When developing this scenario, the lower limits of the attribute levels used in the stated choice experiment (see Nkurunziza et al, 2012a) served as a baseline and represented the daladala characterised by overcrowding, longer travel times and unregulated fares among others. During analysis, the 'DART' and 'Without DART' scenarios were represented by the DART Phase 1 corridor and daladala route networks respectively.…”

“…As each respondent was presented with nine choice scenarios (see Nkurunziza et al, 2012a), the potential total number of observations (pseudo-individuals) was 6156, a reasonable sample size for choice modelling. Normally, 500-1000 sample observations are more than adequate to give good estimations (Hensher et al, 2005).…”

“…Details of the survey development and administration have been described in (Nkurunziza et al, 2012a). In brief, survey samples were obtained from individual commuters at the age of 15 years and above who travelled on a regular basis to the central business district for main activities such as: work, school, business and recreation.…”

“…Three attributes: travel time, travel fare and (in-bus) comfort were selected and considered for the study (see, Nkurunziza et al, 2012a for more details on the DART attributes). The selection of these attributes and their level values were based on work sessions held with DCC and DART agency local staff and the information collected from a pilot survey among a section of current public transport regular commuters to the Central Business District (CBD).…”
