In CERM 10 there are the following formulas:
Stopping Distance = Sstopping = vtp + sb
Stopping Sight Distance = Sstopping =1.47vtp + sb
Example:
A car skidded to a stop while travelling 55mph. The driver took 0.9 seconds to react. What was the total stopping distance travelled? I thought you would use the Stopping Distance formula above but it appears you should use the Stopping Sight Distance formula unless the answer I have been provided with is wrong. Which formula should I be using?
Thanks.
