Interesting map showing the change in vehicle volumes on major roads for last few years.
Most Edinburgh arterial routes dropping but FRB and M8 increasing

Interesting, though some sections of the bypass have increased whereas other sections have reduced? Same on A71??

It's not too hard to envisage an "Ocean Terminal Effect" or a "Fort Kinnaird Factor" on that map.
Build it and they will drive.

Ah maybe, but with ten per cent less traffic on all the feeders to the hot spot? It is not perfect but it is interesting

If you click through on individual stretches of roads it gives you the number of AADT (Annual Average Daily Traffic).
You have in the West for 2013:
Forth Road Bridge 76,988
A8 Airport 44,119
M8 J1/2 63,131
A71 Heriot Watt 15,789A90 Queensferry Rd (Davidsons Mains) 43,506
A8 Corstorphine Rd 22,063
A71 Gorgie Rd 26,458I ititially thought that they didn't seem very much but then I realised that it means 15 vehicles a minutes pass the zoo each and every minute. Big numbers...

"It means 15 vehicles a minutes pass the zoo each and every minute"
An even more interesting statistic would be how many people pass each and every minute. Excluding buses, would it be many more than 15?

How about this...
A9 Drummochter 6,813
A96 Keith 6,005Hmmmm....
Also
M74 extension 71,927
Surrounding roads - going upPosted 9 years ago # -
Anyone have any theories about what happened in 2009/10 that caused the traffic on Gt Junction St and Ferry Rd (as far as Granton Rd) to increase so much when the connecting road volumes went down?

I'm fairly sure that the annual flows are not counted each year at most sites. At some sites there is a steady trend (based on average national trends?), then a sudden jump (up or down) as the figures are corrected with a count that year.
There is a file available from the DfT website with raw counts that shows when actual counts were taken, and other figures were factored after that, until another actual count is done.Also, see http://www.transportscotland.gov.uk/map-application with more detailed counts although mostly only for trunk roads.
Thinking more about this, the CBT growth/shrinkage map can't be reliable in many cases, as it is comparing 2 different sets of DfT figures, either or both which could well be wrong.Posted 9 years ago # -
@ih another possibility is tram works in Leith, the widespread road closures to move utilities.

from the raw count data ), the estimated changes in Gt Junction St appear to be based on 2 12-hour counts, 1 on 28/06/2002 and 1 on 02/10/2009, and in Ferry Rd (as far as Granton Rd) are based on 2 12-hour counts, 1 on 14/05/2001 and 1 on 07/05/2010. North Junction St showed less change but it only had one count, on 03/09/2008.
The data wasn't meant to be reliable at such local level but to build up national estimates, with all the errors (each relatively small on a national scale) hopefully cancelling out at wider level.

When you see these kind of figures, it makes you think the council's target of 20% cycle use does seem ludicrously optimistic, doesn't it? (For instance, using the figure for the A90, we'd need to see just under 9,000 people riding through the parallel Barnton path).

It affirms my (rare) driving experiences on long trips - I tend to depart Glasgow around 00.00-02.00 and often get to Carlisle having seen 10-15 other vehicles travelling South and equally little traffic coming North.
Traffic volumes overall really have dropped off a cliff, even in Glasgow at Charing Cross, the roads will be locked in motor traffic at 17.00 and by 18.30 I can look almost 1 Km West along Sauchiehall St and not see a single moving motor vehicle.
Part of Glasgow's problem is the unrestrained building of parking spaces in the city centre, and the resulting lock-up as the cars to fill them up all try and arrive or leave at the same time. Do the maths - say it takes each driver 6 seconds to get into the traffic flow on a street and underway - and around 20,000 of them all tray to do this at 17.00 with a limited number of outlets to feed them on to the M8 do 20,000 at 10 cars/minute (which is a bit optimistic IMO) = 2,000 minutes split over say 20 route-lanes out of Glasgow = 100 minutes = 1 hour 40 min of gridlock, discounting buses and HGV as a very small % of vehicle count. I rest my case....

"Part of Glasgow's problem is the unrestrained building of parking spaces in the city centre"
And the climbdown on the workplace parking tax plan -
After studying the responses to a consultation paper, ministers have decided to abandon the controversial proposal - but will press ahead with plans to introduce charges for motorists in congested cities and impose a workplace parking levy.
Transport Minister Sarah Boyack has refused to comment ahead of a formal statement to the Scottish Parliament on Thursday.

I think the finger points to Jack McConnell
