So this setup is a mix of a Montréal Advanced arrow (the kind where the right turn arrow comes on when the pedestrian clearance phase starts) and flashing yellow arrow. The bus priority phase always goes first, followed by phase two and five (flashing green arrow). Once phase six starts, the through arrow will display and the right arrow will flash yellow. The walk phase is set to "rest in walk" for the duration of this phase. If you press the side street pedestrian button, the green arrow displays (bi-modal) and pedestrian clearance begins. The "emergency priority signals" will only display if a preemption is called. The side street phase is the same as before (Montréal Advanced arrow and an advanced walk and PED clear before phase eight turns green).
Another preemption will recall the bus priority signal. Eventually I'll have detectors and the Opticom system set up to run this sequence but manual buttons will do the trick for now!
