Transport Analyst accounts for transit and land use data to evaluate the performance of impact of current transport systems and assess how various system changes would alter performance. It's an open source tool developed by Conveyal and is the primary tool they use when preforming consulting services.

Analyst goes beyond basic statistics of how far or fast a system can carry people. By layering information from OpenStreetMap and census data, it allows planners to view accessibility. For example, Analyst can display job opportunities, businesses, and various amenities that become more accessible to people living a new planned transit line. In this way it ties in land use planning. It is geared to intake multiple alternatives and quickly display graphical prototypes that compare accessibility outcomes for the different scenarios.

Analyst can be run on a web interface that allows for public outreach and consultation. The map allows users to see the impact alternative scenarios would have on them and to make recommendations as a result. It can output maps in GIS format to easily integrate results into publications and reports.

Analyst allows for multimodal analysis, incorporating walking, cycling, transit and driving. this simplifies planning when accounting for park-and-rides, bikes on transit, and bikeshare systems. Using demographic data from census inputs, Analyst can do equity analyses and reveal disparate impacts that any scenario might create. Not only is it important to ensure transposition development is equitable, but this step is crucial in the US where agencies are required to comply with Title VI.

Conveyal's commitment to open data and open source has led them to use open data for all of Transport Analyst's inputs, such as publicly available GTFS feeds, map data from OpenStreetMap, and census data. The components for Analyst are themselves open source, licensed under the Apache 2 license.
