Movable speed indicators have been in Abingdon for nearly two years, but this is the first time I’ve seen one working so close to a long-standing speed camera. This is on Audlett Drive in Abingdon, where the limit has recently changed from 40 mph to 30 mph.
While I watched for a couple of minutes, all the cars were at or under the 30 mph limit.
Which works better: the carrot or the stick?
Are the Gatzo cameras still in use?
I like the speed indicators, if my speedo says 30 they say 27 so I tend to go a bit over, then they dont ususally prosecute if you’re less than 10% over so you could do an indicated 33 on the sign, which is about 36 on your speedo. Also I have gone past speed indicators using cruise control and doing a perfectly consistent speed but as I go past the sign the indicated speed changes, so I have my doubts about their accuracy. If it was now and again I would put it down to variables, but it’s consistent and repeateable.
There is also the indicator on the South bound Oxford Rd near the junction with Norman Ave. It triggers a red warning if the detected vehicle is exceeding 20mph, but the speed limit there is 30, the 20 doesn’t start for another 50 yds
