Isn't there provision for data providers to give a mean speed or do you want to cover the case where no speed is given. If so, determining the avg. speed is pretty much impossible on a global scale as it's dependent of what the content provider uses for threshold. I remember in Paris an urban highway segment (speed-limit usually 90kph) is considered clogged if the avg. speed falls under 30 kph and it keeps that state until the avg. speed rise above 60 kph. But it is probably different values in some other cities (or on different type of roads where those limits are not adapted). _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
