PT Trip Count

This indicator displays the average number of public transport departures per hour for each public transport stop.

1. Explanation

The Public Transport (PT) Trip Count shows the average number of public transport departures per hour for a selected time interval for each public transport stop on a point layer. The results can be visualized either as a sum of all transport modes or by focusing on one dedicated mode (e.g. bus, tram, metro, rail).

This indicator serves as the foundation for the ÖV-Güteklassen, but can also be utilized on its own as a straightforward measure for public transport offer at a station level. It gives a summary of a station’s departures during a specific time window and day, providing a valuable overview of the public transport offered in a city. Thus, the indicator is often used in weak point analyses of local transport plans (see, among others, Guideline for Local Transport Planning in Bavaria).

info

The public transport (PT) trip count is only available in areas where the transport network is integrated into GOAT.

In case you need to perform analysis beyond this geofence, feel free to contact the Support and we will check what is possible.

2. Example use cases

• Which stations in the city serve as main hubs?
• Which stations have low service rates in comparison to others?
• How does the public transport quality vary over different times of the week or day?

3. How to use the indicator?

1

Click on Toolbox .

2

Under the Accessibility Indicators menu, click on PT Trip Count. This opens the settings menu.

Calculation Time

3

Select for which Day, Start Time, and End Time you would like to calculate the public transport trip count.

Reference Layer

4

Select the Reference Layer that contains the area for which you like to calculate the indicator. This can be any polygon feature layer.

5

Click on Run. This starts the calculation of the Public Transport Trip Count for the selected area and time interval.

Hint

Depending on the size of the selected area, the calculation might take some minutes. The status bar shows the current progress.

Results

6

As soon as the calculation process is finished, the resulting layer called "Trip Count Station" will be added to the map.

7

When clicking on a point in the map, you can see the station name, total departure count, and the departure counts per mode.

Hint

If you are interested in one specific mode, e.g. only busses, you can use the attribute-based styling to adjust the point color based on that desired column.

4. Technical details

Similar to the Public Transport Quality Classes (German: ÖV-Güteklassen), this indicator is calculated based on GTFS data (see Inbuilt Datasets). Based on the selected day and time window, the average number of departures per hour (regardless of direction) is calculated.
