Zeitabhängige Sperrungen und Nutzungsbeschränkungen von Straßen werden bislang in keiner frei verfügbaren Software zur Routenplanung genutzt. In dem im März gestarteten Projekt “TARDUR - Temporal Access Restrictions for Dynamic Ultra-Flexible Routing” gehen die Universität Heidelberg und die Firma GraphHopper dieses Problem an. Das Projekt wird im Rahmen der Förderrichtlinie Modernitätsfonds (”mFUND”) mit insgesamt 100.000 Euro [...]
Alle Jahre wieder blühen die Kirschbäume vor unserem Institutsgebäude in voller Pracht und laden Passanten allen Alters ein zum Verweilen.

Time-dependent restrictions and temporal road closures are so far not considered in any freely available software for route planning. Heidelberg University and the company GraphHopper aim to address this issue in their joint project “TARDUR - Temporal Access Restrictions for Dynamic Ultra-Flexible Routing”. The project started in March and is supported by the Federal Ministry [...]
In a recent article by the NYTimes the openrouteservice API isochrones interface was consumed to derive regions of reachability from subway stations in New York City. Their findings show that two-thirds of 550.000 residents who have difficulty walking live far from an accessible subway station. Head over to this very interesting analysis which you can find [...]
