The traffic light signal staging is fairly simple. It has 5 stages technically, but it is really only 3. 1 is a simultaneous green stage. All cyclists and all pedestrians get green, the cyclists able to make diagonals if they want. This lasts about 20 seconds. The third stage is NB and SB thru movements and the right turns from northbound and southbound flows. This lasts for 22 seconds. The second stage is a very short one, it's essentially a queue jump for buses, who get to leave their bus lane 6 seconds before motor traffic gets to. It applies in both directions and traffic turning right from the northbound and southbound flows also get a protected right turn. Note that all right turns are protected, but are prohibited on red. The fourth and fifth stages are a rotation 90 degrees to the right or left of the second and third. It has a (maximum) cycle length of 76 seconds, plus all red and amber clearance times, and a maximum wait of 56 seconds. Under a minute. Note that all left turns except by bicycle are prohibited. Buses do not need to make a left turn anyway.
Buses get their queue jump phase, which lets them go ahead of traffic. In downtown they mostly alternate.
