BREEAM Transport Assessment and Travel Plan

Bicycles-4245347 640.jpg


[edit] Aim and benefits

To reward awareness of existing local transport and identify improvements to make it more sustainable. To encourage more sustainable forms of travel and reduce the reliance on cars.

[edit] When to consider

[edit] Step-by-step guidance

The site-specific transport assessment or statement must cover the following (as a minimum):

The travel plan should include a package of measures to encourage the use of sustainable modes of transport and movement of people and goods during the buildings operation and use. To include:

If the occupier is known, they must be involved in the development of the travel plan and they must confirm that the travel plan will be implemented post construction and be supported by the building’s management in operation.

[edit] Calculating the Public Transport Accessibility Index (AI):

Collate the following information to determine the public transport Accessibility Index (AI) of the assessed building:

Use the BREEAM Accessibility Index tool to calculate the AI.

Tra01.2 : Default hours of operation by building type for a typical day

Building Type Default Hours
Commercial 08.00-19.00
Preschool, school, 6th form college 07.30-10.00, 15.00-17.30
Further & Higher Education 08.00-19.00
Healthcare 07.00-20.00 (encompassing visiting hours and typical daytime shift patterns)
Retail: Shopping Centre 09.00-19.00
Retail:Supermarket 08.00-22.00
Retail:Service provider 08.00-18.00
Retail: Convenience store 07.00-22.00
Retail: DIY or retail park 08.00-20.00
Retail: Shop 08.30-17.30
Multi-residential accommodation 08.00-19.00
Court 08.00-19.00
Prison 07.00-20.00 (encompassing visiting hours and typical daytime shift patterns)
Other buildings 08.00-19.00 Or use any of the above hours, as appropriate to the building type
24-hour use building 07.00-20.00

[edit] Calculating the average number of services

For the AI calculation, the frequency of public transport is the average number of services per hour. This average is calculated by determining the number of services stopping at the node (during the peak arrival and departure times for the building or the building's typical day’s operating hours, see definition of 'operating hours') divided by the number of hours within that period. For example, the average number of services for a building that operates between 08:00–19:00 hrs (11 hours) within proximity of a bus stop with 35 stopping services during this period is 3.2 (equivalent to an average service frequency of approximately 20 minutes).

[edit] Multiple services

Services that operate from more than one node within proximity of the building, the same bus serving two separate bus stops, must be considered only once, at the node in closest proximity to the building. Different services at the same node count as separate services.

[edit] Bi-directional routes

Routes will be bi-directional; however, for the purpose of calculating the index, consider only the direction with the highest frequency (in accordance with the PTAL methodology).

[edit] Campus or campus-style developments - entrance to consider when calculating the AI

The main entrance, to the campus, e.g. further or higher education sites, can be used to determine the distance to a compliant node if 80% or more of the buildings are within 1000m of this entrance.

If the site has more than one main entrance, either entrance can be used for the calculation.

Where less than 80% of the buildings are within 1000m of the campus’ main entrance, the assessed building’s main entrance must be used to determine the distance to a compliant node. This aims to encourage the location of public transport nodes inside or on the periphery of large campuses.

[edit] Buildings in Greater London

The transport for London Planning Information Database allows users to search for a specific London location by street name, coordinates or postcode and then calculate the Accessibility Index (AI) for that location. The Total AI is confirmed for the Point of Interest (POI) within the summary report, which can be downloaded and used as evidence of compliance for the assessed building. See

[edit] Operating hours in a typical day

A typical day represents the period when travel to and from the building by its users and visitors will be at its highest. For most buildings this should be taken as a mid-week day. In choosing a typical day the assessor should check that timetabled information for that day is, within reason, representative of the public transport provision for the entire operating week (excluding Sundays).

BREEAM considers a building’s accessibility to be defined by how readily the public transport network can be used by the majority of building users travelling to and from the building. In most cases the normal operating hours of the building can be used. Where shift patterns see the majority of building users (over 80%) arriving or leaving during a certain period, for example an office building where the majority of office workers arrive between 8.00–10.00, that period can be used as an alternative to the operating hours of the building. This accounts for some building types that operate a 24-hour day and on a shift work basis. During typically deemed unsociable hours, where there is little if any public transport operating, such periods do not need to be accounted for in the assessment of this issue. Where the assessed building operates on a 24-hour basis or the operating hours are unknown at the time of assessment, use Table Tra01.2.

[Building users (as appropriate to the building type) could refer to staff, pupils/students, visitors, patients, customers, community users, delivery personnel, regular contractors/service providers and residents (multi- residential buildings)]

[edit] Applicable schemes

The guidelines collated in this ISD aim to support sustainable best practice in the topic described. This issue may apply in multiple BREEAM schemes covering different stages in the life of a building, different building types and different year versions. Some content may be generic but scheme nuances should also be taken into account. Refer to the comments below and related articles to this one to understand these nuances. See this document for further guidelines.
