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 Am 21.02.2016 um 17:57 schrieb Gerd Petermann:

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.

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: https://www.openstreetmap.org/directions?engine=osrm_car&route=51.05581%2C13...

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 Dave, The routing is done by Garmin software, so we don't know all details. The (old) img format doesn't have much room for details. The road-speed and road-class are probably the most important values, besides the access restrictions. The Garmin algo also calculates angles at crossings and doesn't like to make sharp turns when in car mode. For long distance routing in car mode the algo prefers to get on a major road and use that as long as possible. So, in short, a bunch of traffic signals may reduce the avg. speed, but my understanding is that this depends much more on the time of the day (rush hour) . I also don't like the idea that the device routes me through rather small roads to avoid a crossing with traffic signals. I know such a place in my neighbourhood and the "clever" route is used by many cars, even though it goes through a tempo 30 zone and across bumpers.

Februar 2016 00:56 An: Development list for mkgmap Betreff: Re: [mkgmap-dev] Option "link pois to ways" 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.
