A bottleneck occurs when which condition exists?

Explanation:
Bottlenecks arise when the number of vehicles wanting to pass a point (demand) exceeds what the roadway can handle at that point (capacity). When demand surpasses capacity, a queue forms and speeds drop, so traffic backs up and becomes congested at that location. If capacity is greater than demand, traffic flows smoothly and no bottleneck occurs. Merely all vehicles traveling at the same speed or having zero traffic doesn’t create a bottleneck; the key factor is demand exceeding capacity.
