Passengers per hour per direction

Passengers per hour per direction (PPHPD) is a commonly used metric in the transportation industry, especially concerning public transit systems. It measures the number of passengers transported in one direction by a transit service within an hour. This metric is essential for several reasons: 1. **Capacity Assessment**: It helps transit agencies evaluate the capacity of their services and understand peak demand times. 2. **Service Planning**: It allows for better planning and optimization of transit schedules and frequencies.
