Product Overview

The Public Transport Accessibility Level (PTAL) is a method used by transport planners to assess connectivity of a given location to the public transport system. Each PTAL grid square represents the distance to the nearest public transport node and service frequency at those nodes. The result is a grade from 1–6 (including sub-divisions 1a, 1b, 6a and 6b), where a PTAL of 1a indicates extremely poor access to the location by public transport, and a PTAL of 6b indicates excellent access by public transport.

The PTAL is calculated for a 100m by 100m grid, overlayed on the area, and uses frequencies of service for the hour of 8.15 am to 9.15 am as according to the Transport For London (TFL) methodology.
