An analysis of the determinants of local public transport demand focusing the effects of income changes

摘要

Purpose In order for public transport to be a part of the solution to the environmental problems caused by traffic there need to be a clear understanding of how, and to what extent, different factors affect demand. There still seem to be some confusion regarding some key relationships, one of them being the effect of income on public transport demand. The purpose of this article is therefore to provide empirical estimates of how different factors, including price and car ownership (although income being the main issue), affect the demand for local public transport.
