With map representations that correspond well to the important environmental features perceived by the PVIs (Lobben & Lawrence, 2012), potentially enhanced with audio and interactions (Brock et al., 2015), the maps can efficiently assist them to acquire the necessary spatial knowledge for their journey. But the maps are often not available for road crossings, especially complex ones with traffic islands, which are particularly challenging in the journeys of PVIs. Most existing mobility-related automated tactile mapping tools work on the scale of neighborhoods with more emphasis on road networks and building footprints (Minatani et al., 2010; Štampach & Mulíčková, 2016; Touya et al., 2019), and even when it's possible to zoom in to a road crossing level (Červenka et al., 2016), there is little detailed information about the layout of the road crossings regarding e.g. traffic islands or pedestrian crossings that are critical to the execution of a safe cross (Wiener et al., 2010). These road crossing maps are still being hand-made by professionals in a tailored and time-consuming manner.
