|Red Light, Green Light
One way transit speeds will be improved in the Chicago-Emerson/Fremont corridor is through “Transit Signal Priority” or “TSP”. TSP is technology where Metro Transit buses can communicate with stoplights to extend green lights.
For example, a bus approaches an intersection where the walk countdown is in the single digits, instead of changing to yellow and then red the bus “asks” the stoplight if it can stay green for 10 more seconds or so. This allows the bus to move through the intersection instead of waiting at the red light. If this is repeated throughout a corridor there can be significant time savings for bus riders. Metro Transit customers can see it in action on many intersections along the A Line corridor.
TSP will be added to 31 stoplights along the Route 5 corridor in late 2017 and 2018. This will give the local route a boost while the rest of the rapid bus improvements are being planned. Riders can expect to save 1 to 3 minutes per trip between Downtown and 56th Street in South Minneapolis.
