What does the term "headway" refer to in transit operations?

The term "headway" in transit operations specifically refers to the time interval between vehicles on a particular route. This measurement is crucial for maintaining service frequency and ensuring that passengers experience a reliable service time. Headway can vary based on factors such as time of day, congestion, and ridership demand. A shorter headway means vehicles arrive more frequently, which is beneficial for passengers, while a longer headway can lead to longer wait times. Understanding headway helps transit operators effectively manage schedules and service patterns to maximize efficiency and passenger satisfaction.
