NAO launches service access journey time tool


The National Audit Office (NAO) has published an interactive tool that compares transport accessibility to key local services across England.

The tool combines the latest available national journey time data from 2017 with other publicly available data on services.

Users start by selecting a service type from the first dropdown option, for instance, schools, GPs, town centres or large employment areas, and then select which journey time map layer they need.


They can then create a national heatmap demonstrating journey times across the country for that service or focus in on specific areas such as local authorities, MP constituencies, local enterprise partnerships, or clinical commission group areas.

A map will appear in the panel to the right showing the journey times users have selected, and give them a shortest, average and longest reading.

The NAO said the tool 'explores whether, when combined with rurality and deprivation, and the quality of the services themselves, variation in journey times is compounding unequal access to services in England'.

'The tool has been designed to add insight, share knowledge and contribute to the discussion around local transport provision and service delivery. It demonstrates new insights available to government through innovative use and analysis of its data. The tool builds on the NAO's previous data visualisations and work on transport and local services.'

This tool can be used to explore:

1. Comparisons of local places' overall transport accessibility to the national average.

2. Average public transport journey times to seven key services and amenities in a given local area.

3. Public transport journey times to health and education services rated good and outstanding, as well as the difference in journey time to reach a good or outstanding rated service, compared to a service with any quality rating.

4. Charts which compare public transport journey times with metrics of deprivation and rurality to look at the interplay between transport accessibility, rurality and deprivation.
