My Level: 3
Reason for request: To amend split in order to force tts instruction.
Thanks
(apologies for zoom level 1, however one of the segments is 3.6 miles long!)
There’s already a “keep left”; I assume you want to introduce a “keep right” too. I agree that this junction meets the standards for a “keep right”. Downlocked.
Just one thing, I think the split for the M53(N) could be moved a little further west, until after the M53(S) slip has irrevocably been missed. At present, Waze will be announcing “keep left” (for the M53(N)) at a point where drivers could still veer across the hatching to take the M53(S). I’d be inclined to shift the (N) split to the point where the road paint separating the (S) split changes from chevrons to straight lines.

Thanks, all done. Can you please double check my alterations whilst locking. Thanks

I’ve been asked to take a look at this. If the intention is to have a keep left/keep right junction, this won’t work. I’m also unhappy with a segment of Major Highway in the middle of the Freeway. Tim reckons it won’t affect routing, but I’m not 100% sure - it is a segment of lower road type.
As currently set up, you will get a “keep right”, although at 42°, the angle is dangerously close to a “turn right”. However, the other direction will give “exit left”, because it’s ramp leaving freeway
The formula for a KL/KR where a ramp leaves a freeway is:
- “Lead-in” segment of Freeway, 6m long, with no name
- Freeway (named) continues in 1 direction at about 30° angle
- Ramp goes in other direction at about 30° - but split it just over 5m from the junction and change that lead-out segment to Freeway as well
So you have Freeway leading to Freeway & Freeway - all the same road type. You have a name change between the lead-in and both lead-out segments.
NOTE If you do this at a motorway junction with a roundabout, this will “break” detour avoidance, which relies on a continuous name through the centre of the junction. If you need to use a KL/KR at such a junction, then you’ll need a continuous alt-name.
Also, see here: https://wiki.waze.com/wiki/Junction_Style_Guide/Interchanges#Configuration
If you use freeway/freeway split, then you’ll get “keep left/keep right”.
If you use ramp/ramp split, then you’ll get “exit left/keep right”, which may be more appropriate in some circumstances, and often looks neater.

Thank you both for your replies and guidance! It was some good bedtime reading trying to understand all the small elements that can affect a junction like this.
I have taken all into consideration, and after trying every single combination possible to determine from the route angle script how this would affect tts instructions etc, I have gone with Timbones’ recommendation of ramp/ramp, but also followed Iainhouse’s guidance on segment length’s.
Many thanks again for both your input. Please double check again to ensure correctness of changes!
