yes you can turn off “traffic influenced routes”
ok WOW! I just was diving into this more and it gets way better folks. By specifying timeType=3 you are giving the “arrive by” time.
So say you start work at 8am, you put that in as your time variable and it gives you a result of when you should leave. This could be epic by flashing your hue bulbs when its time to leave based on traffic. You can also set toleranceBefore and toleranceAfter to give yourself a few minutes leeway. Its also giving you statistical averages based on that time during that day of week if no traffic information is available or its too far in the future. Very cool!
no traffic = flash green @ 7:35
some traffic = flash yellow @ 7:20
tons of traffic = flash red @ 6:45
I suspect the app would have to query the API every minute or so to keep traffic and ETA up to date with traffic conditions.
