London Congestion Charge

From OpenStreetMap Wiki
Jump to: navigation, search

The London Congestion Charge (Relation 3045928 (view, XML, Potlatch2, iD, JOSM, history, analyze, manage, gpx)) is a traffic zone where motor vehicles entering the area pay £10 a day (as of 1 August 2013) to drive on roads inside the Ring Road (Relation 3124618 (view, XML, Potlatch2, iD, JOSM, history, analyze, manage, gpx)). The toll operates from 6am to 6pm on weekdays, except public holidays and the school winter holidays. The toll can be partially or fully suspended during major incidents.

In 2013, Amaroussi identified the need to map the ten-year old charging zone because some road navigation systems were using OpenStreetMap - the absence of such indicators meant that some drivers were accidentally driving into the zone without being aware of the cost. It is extraordinary that in nearly ten years of OpenStreetMap, the London Congestion Charge or Singapore's ERP have not been properly mapped.

Ring Road

The London Ring Road (Relation 3124618 (view, XML, Potlatch2, iD, JOSM, history, analyze, manage, gpx)) is a toll-free circular primary route. It is not the boundary of the London Congestion Charge because of the service roads into private premises (such as a petrol station) and slip roads connecting to roads outside the zone (such as the anti-clockwise connection to the northbound A41), but it is the smallest circular trip possible without entering the zone.

Notice to routing software developers

The London Congestion Charge is now on the live map:

  1. If your routing software supports toll warnings, driving into the area within Relation 3045928 (view, XML, Potlatch2, iD, JOSM, history, analyze, manage, gpx) or any similar area tagged with type=toll must trigger a toll warning.
  2. If your routing software supports avoiding tolls, routes that avoid tolls must avoid the driving into the area within Relation 3045928 (view, XML, Potlatch2, iD, JOSM, history, analyze, manage, gpx) or any similar area tagged with type=toll.
  3. If your routing software supports multiple modes as well, the toll warnings apply only to all motor vehicles except motorcycles, taxi or bus.
