[Talk-us] Speed Limit Validity in US Questions

[Kerry Irons]

Valid until the next speed limit sign.  Painted speed limits on the road are relatively rare on US roads, but are just as valid as a sign.

Hello all,

I'm Horea Meleg and I'm part of the Map Analyst Team at Telenav.

We have some questions regarding speed limits, and your input will be really helpful, because we don't want to wrongly map this feature:

1. A speed limit sign is valid until next intersection, or until next speed limit sign encountered?

2. If it's until next intersection, which is considered as intersection? Any kind of highway type? Or there are some special rules?

For example:

A.	   T intersection it’s considered?
B.	   Cross intersection it’s considered?

 

  - I'm asking this because for example in Europe there are both situations (next sign vs next intersection) depending on country rules.

3.  Speed Limits marked on the road are considered as valid, or just those posted on a traffic sign? Meaning it could be added the information in OSM based on speed limit road markings?

 

Thanks in advance for your input,

Regards,

 

Horea Meleg
