Using GPS technology for demand data collection. Introduction to opportunities and challenges of the methodology in developing and emerging economies

Travel demand data is a necessary basis for urban mobility planning, but especially in developing and emerging economies data availability is often weak or non-existing. The Global Positioning System (GPS) technology offers a cheap alternative for data collection to traditional diary or survey methods. In practice, GIZ (Deutsche Gesellschaft fuer Internationale Zusammenarbeit GmbH) collects first experiences with the methodology in four Ukrainian cities. It shows that GPS tracking technology has reached usability for travel demand data collection. It is cheaper and, when used appropriately, more detailed than traditional survey methods. However, in order to reach high accuracy in detecting trips, modes and trip purposes, high-quality spatial data and public transportation data is needed. Particularly in cities of the Global South, data availability on informal transit is often low. The Ukrainian example has shown that implementing Prompted Recall Surveys in a data collection application for smartphones is a viable option to overcome the issue of data availability and to enhance data reliability. Limited smartphone ownership is a remaining challenge. (A)
