A First Step to Diagnostic of Urban Transport Operations by Means of GPS Receiver

A simple methodology is proposed to quantify operating parameters of urban transport system by means GPS technology of low cost. Parameters such as: travel-time, speed, and delay were analyzed at a grade-separated busway without overtaking and with traffic signals. The system has 10.3 km of exclusive platform, 13 Bus stops, 17 Intersections and 7 U-turns. A mistake up to 10% by distance increase was reduced substantially applying an algorithm. GPS data and corrective method were validated and state-space-speed models were obtained for the route characterization and can be useful to optimization. Fuzzy c-means clustering was used for speed dataset.
