Which vehicle type receives the greatest curb-length allocation?

• A. Taxis
• B. Private
• C. Limos
• D. Public bus

Answer: (D)

Curb-space planning hinges on how long a vehicle occupies the curb and how many passengers rely on that stop. Public buses require the greatest curb-length allocation because boarding and alighting take longer and involve many riders at once. Buses need space for door operation, ramps for accessibility, and to queue safely without blocking through traffic or other stops. This longer dwell time and the need to serve multiple passengers efficiently drive the design to allocate more curb length to bus stops. Taxis and private cars typically stop only briefly for loading or unloading, and limos, while they may have longer stops, occur less frequently and don’t demand as much continuous curb space as busy bus stops.
