Public Transport Accessibility Levels (PTAL) Dataset

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.

Frequently Asked Questions

LAEP+ aligns with Energy Systems Catapult's 7-stage methodology for Local Area Energy Plans, facilitating the creation of best practice LAEPs and project pipelines.

Stage 1: Preparation
‍This includes determining the geographical area, assessing the policy drivers, identifying resources, appointing a lead organisation for mobilisation and establishing the scope of the LAEP.
‍
Stage 2: Stakeholder engagement
‍The development of a LAEP involves a collaborative approach, engaging with external stakeholders to effectively integrate and reflect local perspectives within the plan.
Data Stories is a feature of LAEP+ which enables insights from data models to be communicated to stakeholders using online narratives and visualisations. It can be used to put data insights into context for stakeholders and capture valuable feedback. It can also be used to engage with harder-to-reach stakeholders across the local area. Additionally, LAEP+ includes a consultations feature which enables users to survey a wider group of stakeholders through an online poll.

Stage 3: Understanding the current local energy system
‍In order to successfully plan actions in a local area it is necessary to have a good understanding of the current system, its assets, infrastructure, ambitions, and currently committed plans for the future.
LAEP+ operates a dynamic nationwide building and energy network digital twin that provides the starting point for LAEP analysis. Users of LAEP+ can use the map feature to explore, filter and export hundreds of energy, transport, building datasets in order to understand the baseline of a given area.

Stage 4: Modelling Options for the future
‍By considering multiple scenarios, rather than a single scenario, options and choices for how to meet net zero can be considered. The purpose of this stage is to define for each scenario which combination of actions in a local area reaches the carbon target in the most effective way.
The LAEP+ Scenario Modeller feature enables users to create long-term scenarios, which automatically schedules the rollout of selected technologies based on local renewable potential and users’ own input parameters, such as net-zero targets, budget, and local priorities.
Stage 5: Scenario Refinement and Selection
‍Assess and understand the wider impacts of scenarios produced in Stage 4, specifically focusing on factors that are of interest to stakeholders (e.g., impact on fuel poverty).

Stage 6: Actions, Priorities and Decisions
‍Assess the pathway(s) chosen in Stage 5, and categorise their components based around how soon they can be delivered.
The LAEP+ Projects feature provides seamless feasibility assessments of building-level low-carbon deployments. Click and drop assets onto the map, and run an assessment to view carbon saving breakdowns and cost estimations.

Stage 7: Create the Local Area Energy Plan
‍The final stage brings all of the work carried out during the preceding stages into a single document that is the plan to be carried forward for the local area.
