TRA 01 - Public transport accessibility

Information correct as of 22ndJune 2024. Please see kb.breeam.com for the latest compliance information.

AI calculation – changes to public transport services during the assessment - KBCN1527

The AI is calculated as part of the design stage transport analysis and its value relates to the site location and to informing transport-related design decisions. This must be based on current information, including any planned and publicly-notified changes at the time the transport assessment is carried out. This should be used as the AI benchmark for the assessment. Where later, unforeseen changes to public transport availability are implemented before post-construction certification, the AI benchmark should not be updated at post-construction stage. Assessments should not be disadvantaged by, or benefit from such changes.

Community transport schemes in rural areas - KBCN00013

In rural areas, where scheduled public services are insufficient to gain credits via the calculation of the Accessibility Index, community transport schemes, including 'on-demand services', can be used to achieve the 'dedicated bus service' option. In such cases evidence must be provided to demonstrate:
Content reworded to highlight the availability of the on-demand service to all potential users. 24/04/2017

Demand-based bus services in AI calculation - KBCN1338

Demand-based bus services operated by public transport providers can be included in the calculation of the Accessibility Index. The project team will need to determine an average number of stops per hour to allow input into the AI tool.

Future transport nodes - KBCN0966

Where a transport node is currently inactive but will become active soon after project completion, it can be included when calculating the existing AI. To demonstrate this, confirmation of the start of service date and service frequency from the appropriate public transport authority or company will be required.

No data for AI at Design Stage - KBCN0551

If there is insufficient data for a future transport service to include this in the calculation of the AI at the Design Stage, it should not be accounted for. If at Post Construction stage the data is available, this can be incorporated. Whilst certain Design Stage requirements can be based on commitments to achieve a certain performance, this must be based on verifiable data.
16/04/18 Wording amended to clarify that this applies to future services and to allow applicability to UK NC 2018
 

On-demand public bus services - KBCN1404

These can be recognised as follows: This is limited to genuine on-demand bus services, which are operated as public transport with multiple pick-up and drop-off points and does not extend to private hire, taxi or other similar operations. 

Park and Ride Schemes - KBCN0754

'Park and ride' bus services run from one or more car parks to a city centre or other destination to allow travellers to park their car at a convenient location and complete their journey by bus. These generally stop at transport nodes en route to allow passengers to board or alight. Provided the service meets the aim of the Issue with reference to the guidance, they can be considered for this Issue in the same way as any other bus service.

Safe pedestrian routes: definition, measurement and verification - KBCN0238

Definition Safe pedestrian routes include pavements and safe crossing points, which may be controlled or, for example, be identified by tactile paving, a crossing island or a dropped kerb. An element of judgement may be required, in which case justification should be provided. Measurement Distances could be measured, for example, along a pavement, across a road at a safe crossing point and along the pavement on the other side.  The distance should not be measured diagonally across a road, following the most direct route. Evidence from Google Maps or other digital sources may be used to indicate routes and distances, provided that the scale is appropriate and clearly indicated. Verification The assessor’s site inspection is an important aspect of the assessment of this issue as it must confirm that all relevant information is current and should include photographs of any key areas. This may also help to identify safe crossing points or hazards which may not be apparent from a desktop study. For BREEAM NC and RFO assessments, Google Streetview may be acceptable as evidence to demonstrate safe pedestrian routes and the presence of key features or amenities at Design Stage only. Such information must be verified as above for Final Certification.
07 Mar 2024 - No changes have been made. This appears as 'updated' due to an administrative error.
11 Jan 2024 - Wording re-structured for clarity
19 Dec 2023 - Applicability to BIU V6 confirmed

Tram services - KBCN000004

Tram services are classified as train services when assessing transport accessibility.
