Granularity in Route Directions Generated by Systems and Humans


We address spatial granularity in route directions in relation to information needs in a case study that provides a situation involving different modalities of travel (i.e., walking and travel by public transport). Results reveal that the two sets of route directions investigated (human and web-based) provide the most crucial route elements in hierarchically structured ways that reflect the salient structure imposed by multi-modal traveling. However, human route directions account for the asymmetric information needs assumed for the given scenario in a more flexible and coherent way.
