R.J.R. Macababbad and J.R. Regidor. GPS-Based Travel Time and Delay Survey Methodology and Traffic Data Analysis. Proceedings of the 5th ERDT Conference, Manila, Philippines, 10 Sept 2010.

Abstract taken directly from texts and as such, quoted below:

"Travel time and delay studies are used to evaluate traffic conditions, determine levels of service and to plan for improvements. Transportation planners and engineers of the Metro Manila Development Authority (MMDA) still employ the manual or stop watch method using a test car in obtaining travel time and delay data. This method is labor intensive and is prone to human errors as well as biases inherent in the conduct of the field surveys. Thus, it is necessary to develop and demonstrate a more efficient method using tools for assessment of road traffic conditions. This paper presents a Geographical Positioning System (GPS)-based travel time and delay survey and data analysis methodology. It presents the development and application of a methodological framework and also data analysis and presentation through the use of digital maps. The use of GPS in this research provides fundamental inputs towards the development of a probe car system for use in travel time and delay studies in the Philippine cities."
