|Devices that measure and document traffic violations and their coverage zone|
|* - device|
|Tools for this tag|
This relation documents different kinds of permanently installed devices that measure and document traffic violations, such as:
- speed traps
- red light cameras
- distance between vehicles measuring
- weight check (heavy goods vehicles)
- ordinary traffic checks (papers, use of alcohol, etc.)
- compliance with road toll regulations (currently specifically the Toll Collect system in Germany)
These devices belong to the same class of objects and shall therefore use the same tagging schema with different values. Sometimes a combination of values is required if the device serves more than one function (e.g., both a speed trap and red light camera in one device).
Where to map?
Note that some countries forbid mapping traffic enforcement installations. If rendering or displaying in a routing software or alerting in a routing software is forbidden anywhere, you can add the information to the map - renderer and routing software will make sure to follow the law. Therefore, routing software shall offer traffic enforcement features as plug-ins, so the user can choose if he wants to install the feature.
Traffic enforcement devices are not a place you'd want to go and are therefore not an amenity.
Create a single relation for each traffic enforcement device, if there are several, as each can measure different things to vehicles from different directions.
|type||enforcement||enforcement||The type of relation.|
|enforcement||maxheight / maxweight / maxspeed / mindistance / traffic_signals / check / access||maxheight||The type of enforcement.|
|enforcement||toll||toll||HGV toll enforcement camera bridges in Germany (see Toll Collect on Wikipedia), checking system compliance.|
|maxheight||number; specify unit if not in metres||4||The maximum height (only specify if enforcement=maxheight)|
|maxweight||number; specify unit if not in tonnes||16||The maximum weight (optional, only specify if enforcement=maxweight)|
|maxspeed||number; specify unit if not in km/h||60||The maximum speed (only specify if enforcement=maxspeed)|
The "mindistance" enforcement is for following distance. The "check" enforcement is for a checkpoint.
