A safety index for road crossing

Normally, pedestrians do not walk on streets but on sidewalks. Thereby, crossing the road is often necessary. Particularly in peripheral areas, dedicated crosswalks are rare and pedestrians are forced to cross roads apart from them. In order to integrate road crossing into a routing and navigation system for pedestrians a decision of where to cross the road is needed. In order to express how safe it is to cross the road at a certain location we suggest an index. Among others, the value of the index depends on various criteria as the roads' geometries, the traffic volume and the speed of the vehicles. In order to safely cross a road, a free gap with a certain length between two consecutive vehicles on a lane is required. The calculation of the index is mainly based on the probability of the availability of such a gap. All criteria are directly extracted from OpenStreetMap or derived from them.
