Status: de facto

A fixed road-side or overhead speed camera. Consider using the enforcement relation to provide more information about the speed camera.

How to map

Create a node and add highway=speed_camera

  • This node is located:
    • on the highway, next to where the actual speed camera is, or
    • at the actual position of the camera next to the highway with an enforcement relation.

Tags used in combination

  • maxspeed=* - to specify the speed restriction
  • ref=* - reference number of the device
  • direction=* - to specify the way the speed camera faces, usually in degrees or sometimes with cardinal directions.

Additional information or more complex setups can be stored in enforcement relation.

Additional conditional combinations

If the device for recording traffic violation is located in a section of a road with time/date related maxspeed definition the Conditional_restrictions tagging scheme could be used.

Example 1: A road section with default maxspeed=50 & daytime (06:00-22:00) maxspeed=30:

maxspeed=50
maxspeed:conditional=30 @ (06:00-22:00)
maxspeed=30
maxspeed:conditional=50 @ (22:00-06:00)

Example 2: A road section with default maxspeed=50 & Monday to Friday daytime (06:00-22:00) maxspeed=30:

maxspeed=50
maxspeed:conditional=30 @ (Mo-Fr 06:00-22:00)
maxspeed=30
maxspeed:conditional=50 @ (Mo-Fr 00:00-06:00,22:00-24:00, Sa,Su 00:00-24:00)

Rendering

An icon could be displayed either on the road, or on all affected ways, a little off the road.

Routing

A navigation software shall ask during the installation procedure, whether speed cameras shall be included or not. This shall not be changeable without new installation to make sure there is no conflict with the law in countries where the use of dynamic speed cam warning devices are disallowed.
