Map of speeding (potentially)

    Uber are now offering a map that allows you to view the speeds of motors on various streets (currently only London):

    https://movement.uber.com/explore/london/speeds/query?lang=en-GB&lat.=51.51262&lng.=-0.145438&z.=13&dttpb=ALL_DAY&dtwd;=1,2,3,4,5,6,7&dtdrsd=2018-01-01&dtdred=2018-01-31&ff=

    This could potentially be useful to find streets that suffer from speeding. Unfortunately, the map currently only shows average speeds and speed versus the 85th percentile.

    What would be really useful is if the map were to display the 85th percentile speeds themselves and the highest speed recorded so we can see how bad speeding is...

    That would be useful. It doesn't take long to manually find streets where the average speed is higher than the speed limit.

    Piccadilly Underpass
    34 mph Average
    -14% from free-flow [so 85th percentile speed is 40mph]
    Speed Limit 30

    With a few lines of code, Uber could be sending a map to the Met police saying "These streets are where you'll catch most dangerous drivers".

    Where's the data coming from? If it's anything short of high-resolution, frequently reported GPS then it's unlikely to catch the high but short-lived instantaneous speeds you get on urban roads.

    Where's the data coming from?

    I would guess the mobile phones / devices of Uber (or possibly all) drivers

    Then I guess it might be accurate enough. Of course, highly trained Uber employees contractors would never break road laws.

    Surely you could do that anyway by just logging where the accidents occur?
