Project TARDUR

Time-dependent restrictions and temporal road closures are so far not considered in any freely available software for route planning. We aim to address this issue in the project TARDUR - Temporal Access Restrictions for Dynamic Ultra-Flexible Routing. The project is supported by the Federal Ministry of Transport and Digital Infrastructuret within the mFUND initiative.

Road restrictions may depend on the time of day, the day of the week, or the season. Typical examples are nightly driving bans for trucks, one-way streets alternating between the directions and winter barriers in mountains. If the navigation or routing software ignores these restrictions the user might end up at a closed road. This not only increases traffic and has negative impact on the environment, but also costs time. Especially for emergency and service vehicles such delays are critical.

The goal of the project is to develop and efficiently implement an algorithm that produces high-quality routes with accurate arrival time calculation by taking into account time-dependent constraints. The algorithm will be integrated into the open-source solution OpenRouteService which are publicly available under an open license. The fact that it relys on the open-access OpenStreetMap road network guarantee that a wide range of services, companies and organizations will profit from this new feature.
