London Plan Chapter 6 2x1

Policy 6.3 Assessing effects on development on transport capacity


Planning decisions

A  Development proposals should ensure that impacts on transport capacity and the transport network, at both a corridor and local level, are fully assessed. Development should not adversely affect safety on the transport network.

B  Where existing transport capacity is insufficient to allow for the travel generated by proposed developments, and no firm plans exist for an increase in capacity to cater for this, boroughs should ensure that development proposals are phased until it is known these requirements can be met, otherwise they may be refused. The cumulative impacts of development on transport requirements must be taken into account.

C    Transport assessments will be required in accordance with TfL’s Transport Assessment Best Practice Guidance for major planning applications. Workplace and/or residential travel plans should be provided for planning applications exceeding the thresholds in, and produced in accordance with, the relevant TfL guidance. Construction logistics plans and delivery and servicing plans should be secured in line with the London Freight Plan[1] and should be co-ordinated with travel plans.

LDF preparation

D  Boroughs should take the lead in exploiting opportunities for development in areas where appropriate transport accessibility and capacity exist or is being introduced. Boroughs should facilitate opportunities to integrate major transport proposals with development in a way that supports London Plan priorities.

E  LDFs should include policies requiring transport assessments, travel plans, construction logistics and delivery/servicing plans as set out in C above.

6.14  Allowing development, either individually or cumulatively, that would place an unacceptable burden on either the public transport network and/or the road network would be contrary to the objective of sustainable development. Phasing development (where this is appropriate), the use of travel plans and addressing freight issues may all help reduce the impact of development on the transport network and reduce emissions of gases that contribute to climate change.

6.15  In practical terms, this means ensuring that new developments that will give rise to significant numbers of new trips should be located either where there is already good public transport accessibility with capacity adequate to support the additional demand or where there is a realistic prospect of additional accessibility or capacity being provided in time to meet the new demand. This principle should be reflected in the documentation submitted by applicants and in decisions on planning applications, with appropriate use made of planning conditions, planning obligations and, the Community Infrastructure Levy to ensure a joined-up approach to transport demand and availability of capacity.
