Thank you for this input, Understood the lack of dynamic costing in OSRM. I'll adapat my profile Would it be preferable to lower the rate or the speed of specific way I want to limit ? Maybe both ? I'm not sure to be able to set a rate on a given node isn't it ?
This have to be necessarily relative to rest of my graph All the best Francois *François Lacombe* fl dot infosreseaux At gmail dot com www.infos-reseaux.com @InfosReseaux <http://www.twitter.com/InfosReseaux> 2018-03-28 17:59 GMT+02:00 Daniel Patterson <dan...@mapbox.com>: > Hey François, > > The only way to achieve this with OSRM would be to apply large penalties > to barriers/tolls.
