I'm researching driver behaviour on the approach to signals and need more data on how drivers react and adjust their speed under the following conditions:

1)  lead platoon with red signal - no queue at stopline

2) lead platoon with green signal - queue visible and discharging

3) lead platoon with green signal, anticipating onset of red before stop line is reached

I am interested in the variability in reaction time, point of reaction, deceleration rates over 3 stages- @foot off, @brake applied, and @coasting to final stop
