Abstract: A driving cycle is a standardised driving pattern, described by means of a velocity-time table. The typical driving profile comprises accelerations, decelerations and stops and it is simulated on a laboratory chassis dynamometer. The European Driving Cycle is the common reference in Europe, but this cycle could not describe satisfactorily the driving characteristics in Brasov. The objective of this paper is to propose a realistic driving cycle for Brasov, based on real data collected using the instrumented vehicle method. The onboard data acquisition equipment was GPS devices and the collected data covers typical roads of the city. It was developed a dedicated software tool for analysing data and for identification of the driving pattern. The process has three steps: first, each track is represented as a collection of point and line entities, with custom metadata attached; second, a speed/time diagram is generated for each recorded track; finally, a representative diagram is created after an automated analysis of all the existing diagrams.
