Specify highway types: avoid motorways

keep from trying to route us onto roads inappropriate for running.

Problem: in the current settings runners are routed onto highways which are definitely unsuitable for runners e.g. motorway

Solution: Specify custom_filter in osmnx.graph.graph_from_polygon [1], for an inspiration can be use CityStrides Street Query [2].

osmnx.graph.graph_from_polygon(polygon, network_type='all', simplify=True, retain_all=False, truncate_by_edge=False, clean_periphery=True, custom_filter=custom_filter)

Thanks for opening this issue. You may also find it helpful to see how the existing filters(drive,walk, etc.) are defined to modify, and that can be found in the downloader.py file in the OSMNX repo.

I added following filters 👇, it seems to filter the motroway out.

CUSTOM_FILTER = (
    f'["highway"]["area"!~"yes"]["highway"!~"bus_guideway|bus_stop|construction|cycleway|elevator|footway|'
    f'motorway|motorway_junction|motorway_link|escalator|proposed|construction|platform|raceway|rest_area|'
    f'path|service"]["access"!~"customers|no|private"]["public_transport"!~"platform"]'
    f'["fee"!~"yes"]["foot"!~"no"]["service"!~"drive-through|driveway|parking_aisle"]["toll"!~"yes"]'
)

It should be live on the www.everystreetchallenge.com.

Thanks for you report and time!
