Podaris:Insight Service Level Analysis

Service Level analysis allows you to measure and compare the public transport service level by frequency for zones.

What is Podaris:Insight?

Podaris:Insight is a toolkit for simplifying a number of types of accessibility analysis. It is designed to dramatically speed up the process of performing accessibility analysis on networks and datasets created or imported in Podaris.

It provides a simple interface through which analysis projects can be created and shared, and the corresponding results exported. You can learn more about Podaris:Insight and the analysis types that it offers here.

What is the service level analysis type?

The service level measures and compares the public transport service level by frequency for zones according to set time periods. It allows you to view, at-a-glance, the number of departures in a zone, as well as statistics such as the total number of departures or active stops.
Zones are areas you define and could represent administrative areas like census tracts, or simply an evenly spaced grid.
This analysis type gives a quick way to identify service distribution geographically, but also can be exported to help provide inputs to other workflows.

Step by Step

1. Add basic information such as a name and description that will be visible to viewers of the project.

2 Select a network and a view to be used in the analysis.

3. Define the zones to measure the service level within. This analysis will aggregate and report the serivce level for the public transport stops within each zone in your location dataset. Analysis zones can take the form of locations imported from a dataset, or be drawn manually by clicking the grid button.

4. Define the time period for analysis. The number of departures on stops within a time frame is used to measure the service level of a zone.

6. Click Save and Run Analysis. You will be notified when the analysis is complete.

Interpreting results

The visualisation depicts both the stations and number of departures for the set time period and analysis zones. The number of departures, active stops as well as the average number of active routes and unique trips are displayed, alongside any calculations derived from your dataset queries.

As with PTAL scores, the classes can be defined according to your specifications, either by dragging the classes on the slider:

Classes can also be added or altered in the classes settings, below.


Exporting results

Your analyses can be exported by clicking the project name, and Export Analyse. From here, you can export in a variety of formats, such as GIS and .CSV for either individual or total catchment.
