Purpose
The purpose of this SOP is to ensure that the Planning team is consistently collecting, validating, analyzing and pushing out changes to improve the on-street performance. If this procedure is not followed, it will lead to missing and inaccurate schedule data. It can also cause your agency’s overall on-time performance to decline.
Operational Impact and Metrics
Operational Impact: Schedule data is the backbone of the entire system. This process describes the steps that should be taken after a schedule is published or a service change has occurred to ensure all the schedule changes have the desired outcome. This process focuses on ensuring you are collecting 100% of the scheduled service data, comparing the scheduled times to the actual times, and ultimately using this data to improve schedules which will improve on-time performance and provide better service for your riders.
Metrics: The goal after publishing a new schedule is to resolve all the missing segments, stops and trips in the myAvail system, and validate the data across all services levels. Missing data points can be identified by checking:
- Block logins – should be 100% across all service levels to ensure you are collecting 100% of the schedule data.
- On-time performance (overall) - a comparison of the overall system on-time performance prior to schedule change and after schedule changes were made.
- On-time performance (route by route) - an analysis should also be done to compare the routes that have changed pre and post schedule publish.
Definitions
ITS | Intelligent Transportation Systems |
CAD/AVL | Computer-Aided Dispatch and Automatic Vehicle Location |
Block | All the routes run by a vehicle |
Frequency
This process should be performed the day following a new schedule publish and continue until the on-time performance goal has been achieved. Outside of planned schedule publishes this process should also be performed on a monthly basis to ensure accurate schedule data and to continue to improve on-time performance.
Roles and Responsibilities
Implementation of this procedure is the responsibility of transit agency staff that are involved with importing, updating, and editing schedules.
Procedure
This procedure describes the high-level steps involved in analyzing the daily schedule.
Data Collection
- Run BI Schedule Health report “Missed Stops, Time Points, Trips” report
- Analyze to ensure all data collected (100% of blocks)
Data Validation
- Run “OTP” report
- Run “Running Times” report
- Run “Dwell Times” report
- Compare “actual” performance against “planned” performance - arrival time, departure time, dwell time, on-time-performance, and route adherence.
- It is also helpful to review myStop outputs - real time information for ridership trip planning purposes
Data Analysis
- Identify variances between “actual” performance and “planned” performance
- Determine the cause of performance variation
- Define corrective action required
Schedule Recommendations and Corrections
- Identify schedule corrections required
- Identify schedule improvement recommendations
- Implement schedule corrections and improvement recommendations (see SP-001)
