OSM Inspector/Views/Public Transport - Routes

The Public Transport - Routes view in OSM Inspector shows routes which claim to be routes according to the version 2 of the Public Transport tagging schema.

From 2017-10-09 on, this view is based on the schema version 2 (previously the abandoned proposal by user Oxomoa).

Overview

This view shows routes and validation results of all route relations with public_transport:version=2 and route=train/tram/subway/bus/trolleybus/ferry/aerialway.

The OSM data processing of this view is done by osmi_pubtrans3.

Limitations

The validation engine begin used does only check for a few important errors.

Data sources

All data in this view is derived from OSM data.

Layers

PTv2 route relations

Valid Routes shows route relations which pass all critical validation tests. There are a few tests which route relations are allowed to fail, e.g. tagging of stop positions/platforms.

Invalid Routes shows route relations which fail at least one critical validation test. See below for a list of all checks.

PTv2 route relations errors

Errorneous ways shows member ways of route relations which cause a test to fail or which are next to a gap in the route.

Errorneous nodes shows member nodes of route relations which cause a test to fail or which are an open end in the route (near a gap).

Validation Tests

The railways over railway test checks if a route for a tram, train or subway uses an unsuitable way for that type of vehicle, e.g. a train route running over a railway=construction or way without railway=*.

The road vehicle over road test checks if a route for a bus or trolleybus but uses an unsuitable way for that type of vehicle, e.g. a bus route running over a highway=construction or way without a valid value of highway=*.

The gap and order test checks if a route has gaps or is not ordered properly. The highway/railway members of PTv2 routes must be ordered. The code which does the check does not differ between gaps and wrongly ordered members. If a route is ordered randomly, the code will report lots of "gaps".

The route has way members test checks if a route contains of more than just a collection of stops and platforms.

The general structure test checks if the overall structure of the member list is ok. A route must begin with an ordered list of stops and platforms. The order of stops and platforms is not checked but there must be no highway/railway member before any stop/platform in the list and no stop/platform after a highway/railway member.

The role and type test checks if the roles and types (node/way/relation) of the members is ok.

• Nodes must have only one of the following roles: stop, stop_entry_only, stop_exit_only, platform, platform_entry_only, platform_exit_only
• Ways must have only one of the following roles: platform, platform_entry_only, platform_exit_only, empty role
• Relations must have only one of the following roles: platform, platform_entry_only, platform_exit_only

The platform proper tags test' checks if a platform which is used by a route relation of type X (route=X has the tag X=yes. For example, all platforms of train routes must have train=yes.

Found errors are reported as described in the following table:

Short Message (used in Invalid Routes layer)	Error Message Used in Errorneous Nodes and Errorneous Ways layers	What Is Wrong	How To Fix
error_over_non_rail	rail-guided route over non-rail	A train/subway/tram route uses unpassable ways (i.e. ways without railway=* and without a value of railway=* which is valid for this type of vehicle). Railway tracks under construction are considered as unpassable.	Check if the route still uses this way in reality. Correct either the railway tracks (e.g. if the construction is finished) or change the route (e.g. if the section under construction is not served).
error_over_rail	road vehicle route over non-road	A bus/trolleybus route uses unpassable ways (i.e. ways without highway=*, footways or railway tracks).	Check if the route still uses this way in reality. Correct either the railway tracks (e.g. if the construction is finished) or change the route (e.g. if the section under construction is not served).
(no column)	trolley bus without trolley wire	A trolleybus route uses a road without trolley_wire=*.	Change the route if the road segment is not used by the route any more. Change the road segment if it has trolley wire in reality but that is still missing in OSM. Change the route to type=bus if the it is served by hybrid buses and the road segment has not trolley wire in reality.
	gap or unordered before this way	The road/railway members of this route are not ordered or have a gap. A route must begin with an ordered list of stops and platforms. The order of stops and platforms is not checked but there must be no highway/railway member before any stop/platform in the list and no stop/platform after a highway/railway member.	Open the relation editor in JOSM and sort it manually or use the sort button.
error_unordered_gap	open end at this location
error_unordered_gap	gap
error_unordered_gap	gap or unordered after this way
error_wrong_structure	(unused)	(unused)
no_stops_pltf_at_begin	(not shown in these layers)	There are no stops or platforms at the beginning of the member list. A route must begin with an ordered list of stops and platforms. The order of stops and platforms is not checked but there must be no highway/railway member before any stop/platform in the list and no stop/platform after a highway/railway member.	Check if the route matches the requirement for PTv2 routes. Order if necessary. Add missing stops/platforms.
non_way_empty_role	empty role for non-way object	A member node or member relation has an empty role.	Check if the route matches the requirement for PTv2 routes. Set the correct role or remove the member from the route.
stoppltf_after_route	stop/platform after route	The member list contains stops or platforms after the first road/railway segment.	Check if the route matches the requirement for PTv2 routes. Order the member list.
stop_not_on_way	(unused)	(not implemented)
no_way_members	(not reported in these layers)	The route has no road/railway segments as way members.	Add the road/railway segments used by the route.
unknown_role	unknown role	The route has members with a non-empty invalid role.	Check if the route matches the requirement for PTv2 routes. Assign valid roles to the members.
(not reported in this layer)	platform without proper tags	The platform does not have the necessary tags. Platforms must have at least one of the following tag combinations: public_transport=platform bus and trolleybus routes: highway=bus_stop bus and trolleybus routes: highway=platform train, tram and subway routes: railway=platform	Check if the node/way is really a platform. If yes, add the missing tags. If not, remove it from the route relation.
(not reported in this layer)	stop without proper tags	The stop node does not have the necessary tags. Stops must have at least one of the following tag combinations: bus routes: public_transport=stop_position + bus=yes trolleybus routes: public_transport=stop_position + trolleybus=yes tram routes: public_transport=stop_position + tram=yes subway routes: public_transport=stop_position + subway=yes train routes: public_transport=stop_position + trains=yes ferry routes: public_transport=stop_position + ferry=yes aerialway routes: public_transport=stop_position + aerialway=yes bus and trolleybus routes: highway=bus_stop train and suway routes: railway=station train routes: railway=halt train routes: railway=tram_stop (This is not a mistake!) ferry routes: amenity=ferry_terminal aerialway routes: aerialway=station	Check if the node/way is really a stop position. If yes, add the missing tags. If not, remove it from the route relation.
stop_is_not_node	stop is not a node	Non-node member with the role "stop". Stop positions must be nodes.	Check if the route matches the requirement for PTv2 routes. Assign valid roles to the members.
error_over_non_ferry	ferry over ways other than route=ferry	The route relation uses ways with an empty role which are neither untagged nor have route=ferry.	Check if the route matches the requirement for PTv2 routes. Ensure that the ferry route stays on the water.
