Has anyone any experience of creating gaps for a side road by inserting demands on an adjacent pedestrian crossing sited on the main road? I've seen this in a few locations, and it would be useful to see the signing (if any) that has been used.
I know Lincoln use this facility at the bottom end of the High Street, however this is (was) only for Green Wave gap creation.
And if I recall correctly (if only I could have recalled this the other Friday!!), there IS a facility like you suggest in Featherstone (Pontefract Rd turning in to Hall St) which is (was) unsigned.
Unless the facility is going to be called VERY regularly, I dont think that signing is necessary - apart from of course a "traffic signal cameras" sign !! An occasional use facility, i think drivers will put down to a pedestrian pushing the button and walking away.
We installed one many years ago using a msl u/d to ensure only exiting traffic was detected. Works pretty well. There is a 700 in Mare St hackney that has a C/C loop for buses on an adjacent side road, with a 10 sec call it ensures that only queuing buses use the facility.
We've used this in Lancashire during a diversion for road works, and utilising UTC to generate the demands only during peak hours. No signing was considered necessary. I think a permanent arrangement would be an unecessessary and unjustifiable imposition on motorists, but for traffic management during restricted well defined hours would be OK, and assumed to be absent pedestrians. A UTC response to congestion detection seems a very good operational idea.
We have something similar at Pennycomequick roundabout in Plymouth. Googlemaps will show it very clearly.
In our case there is a crossing on a sideroad (Stuart Rd) across the approach to a small RBT, where a lot of exiting (ratrunning) traffic can hold up the main road (Alma Rd) approach from their left. We have call/cancel loops on the main road, and when the queue reaches them they insert a demand for the peds across the sideroad.
The sideroad onto the RBT has a central island with a Zebra across it, so traffic exiting the RBT isn't held up by the signals.
We had one site in Farnham - now replaced by a full junction control. No additional signing needed as the side road demand coincided with the crossing demand. One way street, so all pedestrians leaving the supermarket and crossing to the main car park all placed demands for the crossing and let the cars out from the side road.
All changed when car park use changed.... now we have problems replacing loops in side road
