Which of the following curb-length allocations matches the landside planning assumption?

• A. 20 taxis, 25 private, 30 limos, 50 public bus
• B. 15 taxis, 20 private, 25 limos, 40 public bus
• C. 25 taxis, 30 private, 35 limos, 60 public bus
• D. 30 taxis, 25 private, 20 limos, 45 public bus

Answer: (A)

The main idea is to allocate curb space based on how long vehicles stay at the curb and how often they stop there. Buses require the most space because they have longer dwell times for boarding and alighting many passengers, so they get the largest share of curb length. Limos take a moderate amount since they have longer stops than private cars but shorter than buses. Private cars need some curb space for quick stops, and taxis typically turnover quickly with short stops, so they use the smallest share.

The option with the largest allocation to buses, a substantial allocation to limos, a middle allocation to private cars, and the smallest allocation to taxis follows this pattern best. It reflects the expected demand and dwell-time differences among vehicle types, giving buses the most space and taxis the least. The other allocations would imply less space for buses or more space for taxis, which doesn’t align with typical landside planning assumptions.
