BRAVO C, Germán et al. Technological Challenges to Measure Vial Traffic in Bogota using GPS and Cellular Communications. rev.ing. [online]. 2013, n.38, pp.45-50. ISSN 0121-4993.

The Traffic and Urban Mobility System (Sistema de Información de Tráfico y Movilidad Urbana -SITYMUR) is a tool used to collect positional data from circulating agents on the roads, in order to generate traffic and mobility information in near real time. This issue raises important technological challenges concerning communications, data processing and publication of the results. This article describes these challenges and discusses the effectiveness of solutions proposed by showing a number of traffic and speed results for Bogotá as well as suggesting possible alternatives for improvement
