Public transport trip generation parameters for South Africa

Abstract

The South African Trip Generation Manuals are widely used in transportation planning, but contain no trip generation parameters for public transport (PT), although such analyses are often required in public transport plans. To close this knowledge gap, this paper has investigated the National Household Travel Survey 2013 and 4 municipal surveys to determine public transport trip generation parameters per average person for a workday. On average a person makes 0.50 PT trips per workday: almost 0.20 for education, 0.20 for work, and some 0.10 for other purposes; a differentiation is given for different geographical areas and income levels. The trip generation parameters for different activities are also investigated. On average a worker makes 0.75 PT trips per workday, 0.5 per scholar and 1.0 per post-matric student; again there is some differentiation per geographical area and income level. These results will be further investigated by the author in his PhD study, and would form the basis for a future South African Public Transport Planning Manual.
