Prior to approval, proposed service changes undergo a technical evaluation conducted by the Metro Service Planning, Scheduling and Development staff. The purpose of the evaluation is two-fold:
- to define and evaluate the impact on riders; and
- to develop appropriate mitigation measures if needed.
Metro uses a comprehensive bus performance analysis process that focuses on mobility, the customer's experience, and resource utilization. Historically Metro used a Route Performance Index (RPI) to determine a route's performance relative to other like services. Metro now uses an additional process that complements the RPI.
This process contains four core attributes using 10 performance indicators, with detailed analytical reports produced quarterly. Lines are analyzed according to their service type, nine specific time periods, and days of operations (weekday, Saturday, and Sunday). This analysis allows the analyst to focus on the performance of a line by time period.
