ABSTRACT
This chapter provides a brief overview of the relevant theory for efficient transport pricing and reviews recent and emerging technical advances that are relevant for enabling transport financing. It summarizes areas where research is needed to realize these possibilities. Increasing the quality of public transport may of course also increase the willingness to pay (WTP) for its services, even possibly to the point where increased revenues may more than cover increased costs. GPS-based road navigation systems are ubiquitous. Traditionally, most of them have relied on static geoinformation-maps, essentially, with the possibility to include real-time alerts about roadworks, accidents. The Swedish systems identify vehicles through automatic number plate recognition (ANPR), but are similar to transponder-based systems from a design point of view.etc., information which is typically provided by transport agencies. The Oyster technology is relatively expensive, however; this is a common problem for dedicated technical solutions which have to carry all overhead and development costs on a comparatively small revenue base.
