The roads to the North of Wembley Hill Road are signed "No through road" and "No access to Wembley Park Drive". Needs survey to find out if this is now true, or just propaganda. If it is propaganda need to code that somehow to disallow their use by auto-routers.

There is a sign here indicating that buses 223, 182 and 83 are diverted up Park Lane on event days. It was an event day, but that was not happening.

Need to:
1) find rule for when they are diverted (may be difficult);

2) trace routes when they are actually diverted;

3) establish whether there is a re-routing in the southbound direction, as well.

There is a choke point on Camrose Avenue that is so narrow that cars need to take it very slowly. I think it may be here, but it could be a long way off.

Both Bing and OS OpenData indicate there is a connection between the service road and the main road here. If not, there needs to be a pedestrian interconnect for sensible pedestrian routing.

Survey needed.
