Perform transit-specific network analysis such as calculating accessibility and visualizing service areas over time using transit-enabled network datasets created in ArcMap or ArcGIS Pro.
The Transit Network Analysis Tools are a set of tools for performing transit-specific network analysis. They are intended to supplement the ArcGIS Network Analyst extension by accounting for the time-dependent nature of public transit and to assist with analyses commonly needed by those working with public transit. For example, the tools provided here can help you perform accessibility calculations and show how the area reachable by transit changes throughout the day.
The Transit Network Analysis Tools must be used with a transit-enabled network dataset created either with the downloadable Add GTFS to a Network Dataset toolbox in ArcMap or using the tools available natively in ArcGIS Pro.
The Calculate Travel Time Statistics tool calculates some simple statistics about the total transit travel time between locations over a time window and writes the output to a table.
The Calculate Accessibility Matrix tool attempts to account for the dynamic nature of transit schedules by solving an Origin-Destination Cost Matrix analysis for multiple times of day and summarizing the results. The user specifies a time window, and the tool will run the analysis for each minute within the time window. In addition to counting the total number of destinations reachable at least once during the time window, the tool output also shows the number of destinations reachable at least 10%, 20%, ...90% of start times during the time window. More detail on the tool output is available below.
The Prepare Time Lapse Polygons tool solves a Service Area analysis for multiple times of day and stores the results in a feature class that can be used to generate a time lapse video or as input to the Create Percent Access Polygons tool.
The Create Percent Access Polygons tool helps you create "typical access polygons" that better represent the area reachable by transit across a time window. The tool attempts to account for the dynamic nature of transit schedules by overlaying service area polygons from multiple times of day and summarizing the results in terms of the number or percentage of the input polygons that cover an area. Areas covered by a larger percentage of input polygons were reached at more start times and are consequently more frequently accessible to travelers.
These tools were formerly included in the Add GTFS to a Network Dataset download, but they are now separate.
