Good morning H C Andersen,
Thank you for your comments and explanations, I appreciate them. The restrictions has been introduced via ANPR (apparently the trial period had traffic wardens stopping/ allowing motorists to get through such zone) to restrict the traffic flow during start and end of school day periods.
The driver was driving westbound on Cobbold Rd with Gayford Rd and Becklow Rd being on the left and right respectively before entering the restricted area (immediately after the junction of these roads). There is 20m or so from this junction to the Stronsa Rd, school's wall that it is within the restricted zone, but the Stronsa Rd to the right heading north then left to Kinnear Rd heading west and then left heading south down Lefroy Rd (basically around the school's wall perimeter bar Cobbold Rd side) is outside the restricted zone.
In the picture "Street map view - Restricted zone in Cobbold Rd W12" I have shown:
-in light blue where the restrictions signs are placed;
-in green the roads leading to the restrictions zone;
-in red the restricted part of the Cobbold Rd.
We don't tend to drive down this road at all due to the road bumpers and use a couple of roads south to pass from Askew Rd to Valetta Rd and surroundings, but the disabled driver was on its own and wasn't aware of such restrictions. We used to pass by when our kids went to school there, but this was many happy moons in the past.
Here are the pictures that I have from the time before I submitted the appeal to LBHF, who refused to take into consideration any of the justifications we gave.

For some reason imgpile doesn't allow me to post a picture of the street map with the indications I had made.
Thank you and regards,
