I guess the speculation is because there is normally a delay of much more than a second and a half between the lights going red for one traffic flow and changing to green for another.
The intergreen period, phasing and stages vary from site to site. This is determined by a number of factors including turn radii, traffic speeds, gradients, lane widths, intervisibility etc. Do you know the intergreen period at the junction where the collision took place? Do you think the people commenting on the article do?
