Public Transport Accessibility Levels (PTALs)

An index of connectivity from a given point in GB to key locations via public transport. The dataset provides an indication of ease of transport, need for private mobility and public transport poverty.

Public Transport Accessibility Levels (PTALs) are a measure of the accessibility of a location to the public transport network, taking into account walk time, public transport service and service frequency. The method is essentially a way of measuring the connectivity to public transport for grid squares of 100x100m. 

Each area is graded between 0 and 6b, where a score of 0 is very poor access to public transport, and 6b is excellent access to public transport.

Public Transport Accessibility Levels (PTALs) are used to design public transport routes, determine Zero Emission Zones, and to identify under-served customers. This service is co-developed by data  partners TransportAPI.

Project RESOP (Regional Energy System Optimisation and Planning )
Project RESOP (Regional Energy System Optimisation and Planning )

Project RESOP (Regional Energy System Optimisation Planning) aims to take a ‘whole system’ approach, by drawing together data from multiple sources into a single tool that can be used to plan retrofit and roll out of low carbon technologies (LCTs) like electric vehicle charge points.

Project LEO (Local Energy Oxfordshire)
Project LEO (Local Energy Oxfordshire)

In November 2021, following a public tender process, Advanced Infrastructure was appointed to provide an energy mapping tool for project LEO utilising Advanced Infrastructure’s LAEP+ software service. This provided an excellent opportunity to test and validate the value of geospatial solutions for local area energy planning.

Spatial analytics for EV charge point siting
Spatial analytics for EV charge point siting

In June 2021, Advanced Infrastructure and EB Charging were awarded funding from the Office for Zero Emission Vehicles to specify and build a cloud-based siting tool for EV charge points. The output was EV Site, an EV focussed instance of our planning tool LAEP+. Advanced Infrastructure’s Head of Product, Lily Cairns Haylor, discusses the challenges of siting EV charge points at scale and the ways digital approaches might accelerate the tricky process.

London’s Burning (fossil fuels)

In collaboration with the Centre for Net Zero, Octopus Energy's not-for-profit spin out, we examined the impact of heat pump uptake between 2021 and 2031. For London Climate Action Week 2021 we visualised and compared a winter's peak in 2021, where Londoners are primarily kept warm by gas, to a winter's peak in 2031 where the rollout of 40,000 heat pumps shift heating demand from the gas network to the electricity network.

How frequently is the data updated?

Bi-annually and in line with major publications.

Where does the data come from?

The dataset is built from publicly available information and augmented by shared data from Regional Transport Bodies, GeoPlace, Highway England. We augment these datasets with additional proprietary methods including manual and automated clearing, rationalisation in order to infill data blackspots.
