All the end of period the equipments were collected and the da were downloaded to a computer. GPS traces were matched to network links using TransCAD 5.0 (GIS software used for data analysis). The information obtained underwent an initial analysis for data consistency and veracity of the routes and finally resulted in maps for each bicycle trip recorded with their origin and destination points. These routes were then assigned to segments of a roadway network map of the city. GPS data including : elevation, speed length and travel time in the segments were joined to the other link attributes necessary for this study : road hierarchy, condition of pavement and cyclist infrastructure.
