Speed limit as rule's road, not as device parameter #343

Hello,

While using my gps navigator, i've sounds notification when I overspeed.

Is it possible to have some overspeed notification as the road's rules, not as device's parameter ?

No, it's not possible. This requires access to some speed limit database. I have no idea how to implement it in an easy and a lightweight manner.

I understand, as a different way, perhaps using geofence polygon as a x speed limit inside ????

vitalidze commented 8 years ago

I will think about it.

Hi,

I agree that It would be nice to have geofences with a defined speed limit that overrides the device's speed.

Some time ago, I read about how to query OpenStreetMap and get the type of a way (highway={primary, secondary, tertiary, residential, service, ...}) and it has also defined an optional tag "maxspeed" (numeric?).

For example, if we look at http://www.openstreetmap.org/way/14519854, we can see the Mallorcan road MA-15 with speed limit=100 and highway=primary.

More info at:

Anyway, I think it would be easier and very useful to be able to assign a speed limit to a Geofence.

Manuel
