Transit signal priority is designed to improve which aspect?

• A. Travel times
• B. Fuel efficiency
• C. Passenger comfort
• D. Bus frequency

Answer: (A)

Transit signal priority is all about reducing the time a bus spends waiting at signals, so the bus moves through intersections more smoothly and quickly. By extending the green phase for an approaching bus or shortening the red phase when feasible, the bus faces fewer stops and less idle time, which lowers the total travel time along the route and makes schedules more reliable. This is the core benefit drivers and planners seek from TSP. While smoother flow can help riders’ comfort and may influence fuel use in some cases, those are secondary effects. It does not directly change how often buses run, since frequency comes from scheduling and fleet size rather than signal timing.
