    Though not my original query, this sounds interesting. I might drop you a line when I have moment to understand what the options are.

    We have a solution that uses an AI that does pretty much what you want, it tracks pedestrians and buses and you can define the logic for the crossing. My email is brian@nowwireless.com i can send you the datasheet.

    Hi – I have once designed a pedestrian crossing to control traffic as a means of providing gaps for downstream vehicles to exit a priority controlled junction in advance of a signal controlled junction, via a call/cancel loop.  Google maps link: “https://goo.gl/maps/owC7MJdPWGc4HRMK6” (you can see the queue loop and can pan along to associated mid block.  Other examples exist particularly at roundabouts for creating gaps in traffic; a key ingredient in my opinion is having sufficient pedestrian demand, you do not really want drivers seeing empty crossings at mid-blocks for the majority of the time.

    This scenario you describe is tackling a different problem, not creating gaps but looking to address a safety concern with the bus stop.  I daresay Plan A should be to relocate the crossing or bus stop so that there is sufficient visibility between pedestrians and drivers; the controlled area (zig-zags) should provide this, or for example building out the footway at the crossing creating more of an inset bay, unless you don’t have the width (see Chapter 6 section 15.5).  I would typically be looking at these solutions, and in any event making sure there is sufficient visibility to primary and secondary signals for approaching vehicles, rather than the solution described.  The first concern that springs to mind is what if the bus is laying over or there is a heavy patron demand, the bus could easily be stopped longer than the pedestrian crossing runs for even if extending the periods to their maximum; in this it would revert to traffic with the bus still in the stop.

    Does anyone have any experience – or thoughts – on using a pedestrian crossing to control traffic. A design incorporates a bus stop very close to the crossing and the client wants the crossing to service the green man when the bus is stopped in case the stopped bus masks a vehicle travelling in the opposite direction and a crossing pedestrian gets wiped out. This would operate independently of any pushbutton input or not. Personally, I think it’s a bit over the top, but would appreciate the views or experiences of anyone else.
