I'm not following re: "pedestrians only get to cross once". In traditional signaling, each crosswalk is also usable by pedestrians once per cycle; no?

- ubernostrum 9y agoA full cycle of the lights involves each direction of vehicle traffic getting a green light once. In a "scramble", pedestrians would only get one total walk signal per cycle of the lights. In a non-"scramble", pedestrians get multiple walk signals depending on direction, just like vehicles do. For example, if a north-south road intersects an east-west road, in a non-"scramble" there will be one walk signal for pedestrians going east-west who cross the north-south road, and one walk signal for pedestrians going north-south who cross the east-west road. Thus pedestrians would get a total of two walk signals per cycle.
- raldi 9y agoSure, under a traditional cycle, pedestrians get two opportunities, but each is for only half the crosswalks.
- jschwartzi 9y agoI would rather clearly own the intersection once than risk getting hit by some moron turning left twice.
- ams6110 9y agoRight -- you also have to consider left-turn cycles when the cross traffic is stopped but pedestrian signals will still be indicating "Don't Walk", and right-turn-on-red where you're counting on drivers seeing you in the crosswalk. Having one cycle exclusively for pedestrians, where there's no confusion, seems safer.
- neilparikh 9y agoAt least in the scramble I've used in Toronto, there's actually 3 walk signals: 1 for each direction (what a regular crosswalk would have) + 1 where you can go in any direction (and all cars face a red signal).
- BurningFrog 9y agoThe standard cycle has 2 phases: 1. Cars & pedestrians can cross one direction 2. Cars & pedestrians can cross other direction "Scramble" has 3: 1. Cars can cross one direction 2. Cars can cross other direction 3. Pedestrians can cross any direction
- neilparikh 9y agoThe scramble I've used has the following phases: 1. Cars and pedestrians can cross one direction 2. Cars and pedestrians can cross other direction 3. Pedestrians can cross any direction
- tryonqc 9y agoThat would be perfect. In Quebec city it is illegal to follow cars in the direction of the green light. If there is a pedestrian signal, you must call for it and wait which makes it awfully long and inconvenient. Takes about 30sec to a min before we can cross most intersection but hey "its safer" they say.
- BurningFrog 9y agoDoes that mean cars can never turn at that intersection?
- undersuit 9y agoIf an intersection is busy enough with pedestrian traffic the left and right turns are impossible without a dedicated turn phase I think the traffic engineers can handle that slight modification. The US has a plethora of lights where turns are made explicit with green/red arrows. As a pedestrian I am not supposed to cross when the turning traffic has a green arrow as the walk sign is always the red hand.
