We said when we ...Essentially: survey methodology. We said when we first saw the DfT survey that it's hopeless at measuring anything. It's bad enough at measuring cars —is counting traffic on the M32 for one single morning a good metric? For cycling, the main roads are in general, bad places to measure. And if alternatives get rolled out, you'd expect people to move there, though again, a single-day survey isn't relevant.<br /><br />w.r.t the Bike Life on: no information on the methodology, hence: no opinion. We don't think much of the Strava dataset though, it's bias towards mamil-roadies self-selects for routes that nobody else would take. Phone data from google would be far more interesting, and cover pedestrian routes too.Bristol Traffichttps://www.blogger.com/profile/17086394853567703369noreply@blogger.comtag:blogger.com,1999:blog-7803191245171285795.post-69192899392453029562016-01-04T16:48:34.201+00:002016-01-04T16:48:34.201+00:00According to the Bike Life report, the number of c...According to the Bike Life report, the number of cycle journeys in Bristol increased by 4% between 2013 and 2014. You suggest that the DfT traffic survey, which shows a levelling off in cycle use, has to be treated with some scepticism. Please could you explain why you think this?Fruity Bluehttps://www.blogger.com/profile/01052465084530923295noreply@blogger.comtag:blogger.com,1999:blog-7803191245171285795.post-42311329399418772882016-01-02T15:46:20.330+00:002016-01-02T15:46:20.330+00:00Latest figures from Bristol (here) show that the n...Latest figures from Bristol (<a href="http://www.betterbybike.info/News/bike-life-taking-pulse-bike-life-bristol/" rel="nofollow">here</a>) show that the number of trips made by bike increased by 4% between 2013 and 2014.bikemapperhttps://www.blogger.com/profile/16902775699101288384noreply@blogger.com
