"Is the time that would be considered as entering for access as opposed to driving through ever defined in these appeals?"No.  I assume that the time threshold has been set so the evidence that the driver did not stop is quite compelling for the adjudicator.For example, if the cameras are 800m apart, and Hounslow set the time threshold based upon the speed limit of 20mph, then if the vehicle travels at an average speed of 20mph, it will take about 90 seconds to travel between the cameras.If the driver claimed 'but I stopped for a minute', that would mean they travelled at an average speed of 60mph before and after stopping.  As this is an average, this means the driver would have exceeded 60mph if their claim is true.So then the adjudicator might:- have a good laugh at the driver's claim- accept the evidence provided by the council infering that the driver did not stop to access a location beyond the restriction- dismiss the driver's claim as not being believableOf course, councils can't enforce speeding (currently) so this is evidence the driver did not stop, not evidence of speeding.  I don't know what the position is if the driver themselves say they have been speeding, in effect.I stand corrected if the maths above is wrong.Also, the evidence only works if the clocks on the cameras are synchronised.  This can be done using GPS or an internet connection.  There are clearly some issues with this way of enforcing the restriction otherwise Hounslow and other councils would be using it in more locations. Maybe there are technical issues, maybe operational. Don't know.

Historically 'except for access' could be enforced if a single camera could cover the entire section of road with the restriction.I think a single camera could enforce this type of restriction on, for example, Devonshire Rd, if it was in place there.I understand that using timing information from two cameras to cover a longer section of road was a deliberate decision by a former head of transport in Hounslow to try something new and different and Green Dragon Lane was the first location in the country where it was tried.  So as things have turned out, being a pioneer doesn't always work and I don't think it has been used elsewhere in Hounslow or anywhere else.  As I speculated, maybe there were complexities with implementation.The challenge with the Grove Park scheme was the high volume of traffic driving through the area between A316 and A4 and A316 to S Circular and belief cameras would be more acceptable to local residents than sticking a bollard in the road at selected locations and forcing certain journeys to be re-routed.The reality is that drivers are on auto-pilot most of the time and don't see signage, so if there had been a change to the road layout at for example, Hartington Road, requiring drivers to slow down or stop, then there is more chance of signage actually being seen.Using cameras to appease drivers was also the approach in LBHF where despite the area having dozens and dozens of road closures put in during the 90s and 2000s, they have used cameras extensively.  Using cameras to appease drivers doesn't work because they will complain about any restriction to driving.The advantage of a physical closure is that people just get used to it and within few years it is just a normal part of the road network.  There are many streets in Chiswick that are low traffic neighbourhoods before they were called low traffic neighbourhoods and residents don't even know they live in one because the road was closed 20 or 30 years ago.
