Headway Departure by Route

Headway Performance by Route Departure

This dashboard displays headway performance by route departures. Using the information in the dashboard, you can identify routes that need performance improvements and set the priorities for these improvements. The information in this dashboard reflects the date range that the filter pane specifies.

The first bar chart displays the five worst performing routes based on their headway statuses. The second graph displays the headway performance for the five routes with the most riders. An impactful route might not have the worst headway performance, but poor performance affects more riders, which might increase the priority for an impactful route.

Between these two bar charts, you can identify the worst performing routes and the routes that affect the most riders. This information can help you target remedial efforts on the routes that need it the most.

If you click a bar for a route in a chart, myAvail opens the Headway Performance By Stop Departure report in a new window. This report displays a bar chart of the headway performance for that route by stop.

Below the bar charts, the report displays a table. This table lists the routes along with various headway and ridership statistics. Click a header to sort the table by that header. Click multiple times to toggle between ascending and descending sort order.

The table includes the following information:

• Route
• #Departures (Act/Exp): Displays the actual and expected number of departures from timepoints on the route.
• %Difference: Percentage difference between actual and expected timepoint departures: 1 - (Actual/Expected). Higher percentages represent a greater number of missed timepoints.
• On-time: Percentage of on-time headway departures for the route.
• Bunched: Percentage of bunched departures for the route.
• Gapped: Percentage of departures that are spread out too much compared to the scheduled departures.
• Bunched Outlier: Percentage of departures that exceed the bunched outlier threshold.
• Gapped Outlier: Percentage of departures that exceed the gapped outlier threshold.
• % of All Reports: Percentage of reports for each route out of all reports.
• Avg Daily Boards: Average number of boards per day on the route for the date range that the filter pane specifies.
• Total Boards: Total number of boards on the route for the date range that the filter pane specifies.

For this dashboard, use the filter pane to apply filters across the entire dashboard. You can use the following specialized filters:

• Show On-time Categories: Show statuses for On-time, Gapped, Bunched, Gapped Outlier, Bunched Outlier headway departures. By default, the dashboard displays all these Deselect the statuses you do not want to see.
• Include Missed Stops: Check to display missed A missed stop occurs when there is a scheduled departure, but the system does not record that departure.
• Include Outliers: Check to display outliers in the report. An outlier occurs when a value exceeds the relevant outlier threshold.
• Include Detours: Check to display data that the system records while vehicles are on a detour. These results might be atypical.
• Routes Monitored for Headway: Filter the report by one or more routes that the system is monitoring for headway. If no routes are selected in this filter, the report displays all routes, including those not being monitored for headway.
• Bunched Threshold (% Under): Specify how to determine that a vehicle’s departure is bunched too closely to the previous vehicle’s departure. When 1 - (Actual difference between departures/Scheduled difference between departures) is greater than or equal to the bunched threshold percentage, the system counts it as a bunched departure.
• Gapped Threshold (% Over): Specify how to determine that a vehicle has departed When (Actual difference between departures/Scheduled difference between departures) - 1 is greater than or equal to the gapped threshold percentage, the system counts it as a gapped departure.
• Bunched Outlier (% Under): Specify how to determine whether a vehicle is an early When a vehicle departs earlier than the threshold number of minutes before the scheduled departure time, the system counts it as an early outlier. Outliers can be tracked separately in this report.
• Gapped Outlier (% Over): Specify how to determine whether a vehicle is a late outlier. When a vehicle departs later than the threshold number of minutes after the scheduled departure time, the system counts it as a late outlier. This report can track outliers separately.
• Stop Departure Threshold: Use this field to exclude stops with very low sample Enter the minimum sample size that BI will display. Smaller values will include more stops but some of those stops will have a small sample size.

Headway Performance by Stop Departure

This bar chart displays headway departure statuses for a route by stop departures over the date range that the filter pane specifies. Use this chart to determine whether any stops on a route have an unacceptable amount of gapped or bunched departures. This chart allows you to identify where a problem exists at the stop level.

Hover the pointer over a bar to display the values for a particular stop.

For this graph, use the filter pane to filter the data. You can use the following specialized filters:

• Show On-time Categories: Show statuses for On-time, Gapped, Bunched, Gapped Outlier, Bunched Outlier headway By default, the dashboard displays all these statuses. Deselect the statuses you do not want to see.
• Include Missed Stops: Check to display missed stops. A missed stop occurs when there is a scheduled departure, but the system does not record that departure.
• Include Outliers: Check to display outliers in the An outlier occurs when a value exceeds the relevant outlier threshold.
• Include Detours: Check to display data that the system records while vehicles are on a detour. These results might be atypical.
• Routes Monitored for Headway: Filter the report by one or more routes that the system is monitoring for headway. If no routes are selected in this filter, the report displays all routes, including those not being monitored for headway.
• Bunched Threshold (% Under): Specify how to determine that a vehicle’s departure is bunched too closely to the previous vehicle’s departure. When 1 - (Actual difference between departures/Scheduled difference between departures) is greater than or equal to the bunched threshold percentage, the system counts it as a bunched departure.
• Gapped Threshold (% Over): Specify how to determine that a vehicle has departed When (Actual difference between departures/Scheduled difference between departures) - 1 is greater than or equal to the gapped threshold percentage, the system counts it as a gapped departure.
• Bunched Outlier (% Under): Specify how to determine whether a vehicle is an early When a vehicle departs earlier than the threshold number of minutes before the scheduled departure time, the system counts it as an early outlier. Outliers can be tracked separately in this report.
• Gapped Outlier (% Over): Specify how to determine whether a vehicle is a late outlier. When a vehicle departs later than the threshold number of minutes after the scheduled departure time, the system counts it as a late outlier. This report can track outliers separately.
