During peak periods, transit agencies typically adjust service by which action?

• A. Reducing service to minimize crowds.
• B. Introducing only local services.
• C. Removing all express options.
• D. Increasing frequency and capacity.

Answer: (D)

Peak periods bring the heaviest demand, so the goal is to move more people quickly. The best way to do this is by increasing how often trains run and how many people each train can carry. Running more trains per hour and using longer trains raises overall capacity, reducing wait times and easing crowding. Options that cut service or limit options don’t boost capacity or speed, and removing express services doesn’t help when lots of riders need to move through the system. So, boosting frequency and capacity is the typical peak-period adjustment.
