I haven't really noticed much about the centre of town, but in the outlying areas, like Kirkliston, where I often cycle, there does not seem to be any difference at all to driving speeds. I suppose it is more difficult in a relatively non-congested area to get people to slow down.

"20mph limit to go ahead across Edinburgh"

I'd be very interested in real data on traffic speeds - don't suppose anyone is aware of any?
The 20mph limit has given me more confidence with taking the lane on streets like Nicolson St, though.

The streets removed from the 20mph limits appear to be:
Balgreen Road
Polwarth Terrace
Roseburn Street
Whitson Road
Bonaly Road
Swanston Road
Waterfront Avenue
Waterfront BroadwayI regularly cycle along Polwarth Terrace and Waterfront Avenue.
The latter is a narrow street (because of parking) that's used by a lot of cyclists, so it definitely needs to be 20mph.
The latter has no reason to be 30mph. It's hardly a high traffic main road.

Rather sad that at least 2 of those streets have primary schools on them...

I suspect Bonaly and Swanston are possibly to do with streetlighting (or lack thereof). Doesn't mean it shouldn't be objected to.

They are gathering speed data on Nicolson Street and Pleasance currently so worth pestering council about it

I think @stiltskin is on to something. The city centre congested streets are often slower than 20 mph anyway. I feel the cowgate is slower now for example all of the time. But wider out of town unpolicable streets retain the 30 mph plus. The worst is kingsnowe which has 40 mph speed despite double parking on street and traffic islands making it single lanes most of the way. Road surface also not great and getting worse. Should be 30 max

You may find this link useful in discussing speed limits. If you zoom/pan to an area and click 'run' it checks the Openstreetmap data for roads with speed limit information recorded for them. It colours the lines according to the code you can see in the left column (roads where no speed limit is recorded in the data appear with a blue line)...
way [maxspeed=20 mph] {color:green;}
way [maxspeed=30 mph] {color:orange;}
way [maxspeed=40 mph] {color:red;}http://overpass-turbo.eu/s/koV
The city centre zone speed limits are correct - I did the survey along the zone boundary for this myself a few days after the zone was implemented. Elsewhere there may be errors - please help by correcting the data if you know how, or add a note marking the error using the notes button on the right of the map at http://www.openstreetmap.org (see: http://wiki.openstreetmap.org/wiki/Notes#Using_notes )

Out this week - Police Scotland say they recorded 642 speeding offences in Edinburgh in April - Sept, 2016 down from 761 in same time last year. i.e. less than 4 per day
rbrtwtwn ITOWorld maps might also be useful?

Good map
Any idea how quickly that will be updated with the next 'rollout'.
Posted 7 years ago # -
I think the ITO maps use OSM data and changes appear within a day or so of someone editing OSM.

I found "Meadowbank Thistle F.C." on a bing maps layer the other day, over Meadowbank stadium, 21 years after the team left and relocated and renamed to Livingston. I tweeted this to bing and they said it would be included in their next updates.

Would be interesting to see a timelapse of the ITO map "turning green"

Did you know that reducing your speed by 1mph reduces collision rates by 6%? Life is better at 20.

"Out this week - Police Scotland say they recorded 642 speeding offences in Edinburgh in April - Sept, 2016 down from 761 in same time last year. i.e. less than 4 per day"
It's an astonishingly poor rate of detection.
When I lived in Royal Park Terrace, I saw drivers break the 30mph speed limit at least a dozen times a day (that's the ones I actually saw, not the other 80 I didn't see)...
... and then I found out that the speed limit in the street was only 20mph...!
Posted 7 years ago # -
Give me a speed detector and I will find you hundreds of drivers on London Road going over 30mph.
Posted 7 years ago # -
Drivers somehow mange to speed on my street: a cul-de-sac, less than 300 yards long, often littered with double parked cars at jaunty angles, creating a slalom course. The only official traffic calming is widened pavements and a raised table at the junction with Easter Road.
If they speed there, they can speed anywhere!

I forgot about checking for an ITO map when I set the Overpass-Turbo query up. This is essentially exactly the same thing as the Overpass-Turbo map provides... although you can change the settings on the Overpass_Turbo map to show what you want.
Also the Overpass Turbo map will show a change as soon as it is uploaded (it queries the data directly when you click run). Not sure how often ITO update the maps - I've always assumed it to be either instant or at least within a day or so.
The real question on how long it takes for the maps to be updated is then about how enthusiastic your local community of OSM mappers are feeling... (and particularly whether it's there are some sunny weekends or not). I did the city centre in a few hours (with a bit of help from some others). The outlying areas will be more complex I think - particularly where they intersect with existing 20mph zomes.

Before reading the article, try and guess who said this:
We always said that if you start enforcing it you will see a fall in public support because people will feel they are caught speeding on roads that look and feel perfectly safe.
Posted 7 years ago # -
Some might consider that too easy. Have they stopped using their new name already?
Posted 7 years ago # -
Easy to guess BUT is that really what his organisation believes?
I thought it was smarter than just saying 'drive the way you think is fine'(?)
Maybe he is just talking about his members who have had some advanced training??
Posted 7 years ago # -
So people will be upset if they are caught speeding when they think it's OK?
So people will be upset if they are caught without a seatbelt when they think it's OK?
So people will be upset if they are caught texting when they think it's OK?
So people will be upset if they are caught over the limit when they think it's OK?
Perhaps so.
But is the general public going to be supportive over speeding but not the others?
Either all four are no longer acceptable or just three or maybe it's back to two due the opinion forming of people whose main job ought to be encouraging better driving not being an apologist for all drivers.

If Google can use mobile phone data to inform drivers about traffic density, then it would surely be possible to use mobile phone data to map speeding in order for planners to know where to implement changes to the road design, or police to target enforcement?
Posted 7 years ago # -
In fairness the article is balanced and gives a range of different views on the matter. Pleasantly surprised to be honest.
Posted 7 years ago # -
The issue isn't the balance of the article - ought to be expected (even in EN!)
It's inevitable that NG is the go-to rent-a-quote, just disappointing that he is an apologist for law breaking drivers.
Posted 7 years ago # -
That is also true!
Posted 7 years ago # -
I hardly think that a straw poll set up by the EN and then presented as fact could be described as "balanced"
Posted 7 years ago # -
That's true too!
