How to build routes with JOSM
JOSM [1] is an editor for OpenStreetMap. We use it to clean raw gpx data and to add OSM relations between routes and bus stops.
- Upload the gpx track for your route. This will guide us in building the route.
- Upload Mapnik map as background.
- Customize track drawing in such a way that trackpoints are more visibles and colors help you to understand the correct direction.
In OSM a route is a relation among ways and nodes (i.e. bus stops). A route relation is defined by some tags.
- ref
- name
- route = bus
- type = route
- direction
- from
- to
- network
- operator
Ways and bus stops are members of a route relation. We will see in next sections how to add members.
- Open the Relation Editor for your route.
- Select a way on the map and add the selection to the members of the relation.
- Ways must be in the correct order (from the start end to the last end of a route) and connected. You can see if it is connected from the graph on the right of members table.
- If a way is not connected, you usually have to change the role of one or more ways. The role for a way is forward or backward. It refers to the orientation of the way on the map (when a way is selected, you see some little red arrows, that is the orientation). "Forward" means that a bus travels following the direction of a way, while "Backward" means that a bus goes in the opposite direction.

We follow this proposal. In order to define a new bus stop, we need two nodes: one for the actual stop off the street (platform) and the other one where bus stops on its route (stop).
Platform node
- public_transport = platform
- name
Stop node
- public_transport = stop_position

- Resolve conflicts if any.
- Do not push your changes to the server if there are errors.
