Bumper-to-bumper car crowding at signal slows traffic: Study
A US-based study has found that crowding cars with bumper-to-bumper spacing at signals slows down the movement of traffic when the light goes green. Researchers suggested that contrary to popular opinion, if cars stopped farther apart, it would help them accelerate quickly. The team found time required for all cars to pass remained fixed for spacing up to 25 feet.
