Red is the most recognizable color, meaning the eye distinguishes it from background colors more easily. And red has been psychological taught to us to mean stop.
White reflects the most light, more than a mirror. This is a big reason safety equipment (signs, lights) are red & white. The reflective material used also increases red and white much more than yellow.
Yellow, although is a highly visible color was chosen for street lines because of its visibility but more so because of its already psychological idea to mean safety. Traffic signals existed before markings and motorist already associated yellow with caution. Yellow and white are also the most contrasting colors to black pavement, hence why its yellow over red.
So it’s not only the colors but what other colors that it needs to contrast with.

I disagree with the statement. "the most visible color is green". if so, why then would most summer camouflage be variations of green? Why would flowers be red and yellow? If green were the brightest then leaves would be yellow and flowers would be green. Also, green leaves are dark to ABSORBE sunlight not reflect it. Green is NOT bright in THIS world!
