So, the number of traffic_signals encountered on one route vs another route isn't even a factor in mkgmp routing? I have been adding traffic_signals to my workload for the past year in hopes it would improve routing accuracy.

How then does routing get calculated? On my Garmin there is a choice for "fastest" vs. "shortest" routes. Usually this choice doesn't make much difference in the overall time involved for a traverse along a route and I always assumed it was because here in Thailand so few of our highways have maxspeed tags. How are these two routing choices handled by makgmap?

Sorry for the extra questions but I am curious to know these things.

Cheers,

Dave

Oh, allright.
Maybe if you have time some day, you could look into it again. I think there are some use cases.
One example where the OSRM traffic light penalty for example seems to have chosen the clever way around the traffic light:

Hi Jakob,

I think this cannot be done with rules, it requires new java code.
I thought about this a while ago and stoped because I doubted that this
would improve routing.

Hi Gerd,

this would be the best solution I think.
So far I found a rule that lowers the speed for the complete road with
the traffic light, do you have one that splits it and adds a lower speed
only on a part, like you said?

Thanks
Jakob

Hi Jakob,

the current code ignores nodes with highway=traffic_signals.
If I got you right you want to split a road maybe 30 m before the node with
highway=traffic_signals and 30 after and set a lower road-speed value for that 60m part?

Hi,

one more question I was not able to figure out from documentation or source.
When the option "link pois to ways" is used, does it automatically
process traffic signals in a way that adds a time penalty for routing
through them in the map data.

Thanks for help on that
Jakob
