Healthy Streets Transport Assessments.
In London, transport evidence is judged on how well a scheme supports walking, cycling and public transport, not only on traffic. We prepare Transport Assessments and Statements in the format TfL and the boroughs expect.
Main guide: Transport Assessments
TfL’s guidance is clear that every planning application in London should show how it encourages more walking and cycling. The Healthy Streets Approach and the Vision Zero aim of eliminating deaths and serious injuries on London’s roads by 2041 run through the whole assessment.
Assessment or statement
A full Transport Assessment is expected for schemes of strategic importance that are referred to the Mayor, unless TfL agrees another approach in writing. Boroughs can also require one for smaller schemes. Where the transport effects are limited, a Transport Statement may be enough, but the borough’s own validation requirements always apply. We confirm the right document before work starts.
What the Healthy Streets format covers
- The site’s PTAL and how people will actually travel to and from it.
- An Active Travel Zone assessment of the surrounding routes, where required.
- Car and cycle parking against the London Plan and borough standards.
- Deliveries, servicing and construction logistics.
- Road safety and the Vision Zero aim.
- Measures, obligations and the Travel Plan.
Trips and mode share
We forecast trips by every mode, using London-appropriate survey data and census travel patterns, and explain the effect on the bus, rail and Underground network where it is relevant. The Mayor’s Transport Strategy aims for 80 per cent of Londoners’ trips to be made on foot, by cycle or by public transport by 2041, and the assessment should show how the scheme helps.
Small schemes and conversions
For flat conversions, small infill and HMOs, the borough usually wants a proportionate note: PTAL, car-free or permit-free arrangements, cycle and refuse storage, and, where parking is in question, a parking stress survey. We keep these short and focused on the questions the borough will ask.
The new London Plan
The London Plan 2021 remains the adopted plan. The Mayor published a draft new London Plan on 16 July 2026, with consultation running to 15 October 2026 and submission for examination expected in 2027. Until it is adopted, its policies carry limited weight, so we apply the 2021 plan and borough policy, and flag where the draft points in a different direction.
