osm2paths 0.0.3

An automatic generator of JSON vector road network graph car tracks from OSM

osm2paths generates car tracks of any small OSM road network, intended to be used in simple traffic simulations. It converts an exported OSM file (eg. map.osm) to a JSON dictionary defining the road network (crossroads and connections), and car tracks (directed traces on commonplace two-way streets).

The tracks’ graph is perfecly smooth - there are no sharp turns and any turn is defined as an infinitely zoomable quadratic Bézier curve - it generates ‘vector’ paths.

=========== USAGE =============

1, place an .osm file inside data folder 2, call generate_rails() to create a .json files, arguments

osm_path (string, required): path to source OSM file (eg. “data/map.osm”) half_gauge (float, default = 2): distance between road’s central line and tracks in meters min_radius (float, default = 4.5): minimum radius of osculating circle of curves in meters drive_right (bool, default = True): regional road specification - True for Germany, False for the UK display (bool, default = True): if set to True, displays generated traces in system window

CODE EXAMPLE:

generate_roads(“data/kjoto.osm”, 1.5, drive_right=False)
