8.4 Transport connectivity – access to public transport
PTALs (public transport access levels) indicate relative connectivity to the public
transport network for any location in London. The term ‘connectivity to the
network’ indicates that the PTAL measure focuses on the proximity to public
transport services, and not on where these services actually take people to or
indeed how accessible they are to all members of the population.
Figure 8.2 shows Greater London PTALs for 2015. Clearly central London is
dominated by high PTAL values, as are other metropolitan town centres, such as
Croydon, Kingston and Harrow. The predominantly radial orientation of the main
public transport corridors is also visible in the figure. Note that PTAL values are on
a scale from 1 to 6, with 6 representing the highest connectivity level.
