[GraphHopper] Mode for road segment

[Yingxiang Yang]

Hi Peter,
     Thanks a lot for your reply! To be more specific about my question: from the raw OSM data, which fields do you use to decide that if a segment  permits walking/biking/driving or not?
Best,
Yingxiang

Hey Yingxiang,

every edge stores flags where there is information for all vehicles (speed and access). With e.g. carEncoder.isForward etc you can read out this information. Within the algorithm it is managed from an EdgeFilter which does all the necessary work. It is passed as argument to create an edgeExplorer:
outEdgeExplorer = graph.createEdgeExplorer(new DefaultEdgeFilter(flagEncoder, false, true));

Regards,
Peter.

Hi there,
    I have one quick question: how do you decide for each road segment which transportation modes (like biking, walking) are permitted?
Best,
Yingxiang
