A coworker was telling me that the yellow line at CalTrain is a lot more important than we might think. If a person was to stand inside of the two yellow lines, the air pressure of a passing train might actually pull them into the train. This is an extremely dangerous situation, in-fact life threatening.
The painted lines provide some confusion, why are there two of them? Why are they both yellow?Which yellow line is being mentioned to stand behind? What exactly does behind mean? What if you don't read English?
This is a pretty simple concept and most people get it, However, when safety is involved it can never be clear enough. This is an interface in-between people and possible danger.
Wouldn't it be cooler if there was only one yellow line? Let's make the other line red, as you would assume it is even more dangerous to stand in proximity of that.
The platform affords that you stand on it. You stand while you wait for the train. Could we use a visual cue to show where?
Some simple improvements could make this a better interface.
