Fig. 8
Flow diagram of movement analysis implemented in adehabitat LT package in R. (a) Map of commuting events (journeys) of one participant during a typical day. The colour scheme indicates the time of day. (b) Segmentation of one trajectory (journey 18:28 in orange in a) using the Lavielle method identified two segments in the data. (c) The corresponding map of the trajectory in colour scale to differentiate the two segments. (d) Projection of segment 2 on the GIS system retrieved from Openstreetmap. The GPS points (blue) overlap with the railway infrastructure shown in magenta. (e) Corresponding map of the participant manual diary logs of that journey (see subsection 3.1). Visual inspection shows a delay in diary input that would result in small errors in model evaluation
