Abstract:
The City of Johannesburg has adopted an Integrated Corridor Management (ICM)
approach to design selected strategic public transport corridors within the city’s Strategic
Integrated Public Transport Network. ICM is the use of all corridor elements to attempt to
optimise the movement of people whilst improving safety and minimising environmental
impact, all at an affordable cost. The ICM solutions developed were corridor specific and
varied between targeted infrastructure upgrades, incentive schemes for minibus taxis,
revitalisation of the rail network, land-use changes, and road-based public transport
interventions. As such, the evaluation of the options required consideration of a wide range
of quantitative and qualitative impact categories within an environment of limited available
time and budget. Multicriteria Analysis (MCA) is a decision support tool that can
simultaneously account for qualitative and quantitative criteria in evaluating strategies and
options. MCA has been applied in various projects globally and across multiple sectors,
including transport projects, with the aim of reducing the number of options to an optimal
preferred option for the stakeholders involved. This paper highlights the challenges and
lessons learned from applying an MCA to evaluate ICM options for two separate transport
corridors in the City of Johannesburg. These included the challenge of ensuring clarity in
questionnaires for participants in the process and the associated interpretation of results
emerging from the process.
