Fast Computation of Continental-Sized Isochrones
MetadataShow full item record
We propose an approach to speed up the computation of isochrones, which are maps showing the reachability of locations given a starting point and a time constraint. The core idea of our technique is to materialize large parts of an isochrone, demonstrating how this can be achieved for multi-modal transport networks in a scalable way. We illustrate the effectiveness of our method with the help of an experimental evaluation.
