Policies of the Highways Agency
9.23 The Highways Agency (HA) acting on behalf of the Department for Transport (DfT) is the Highways Authority for Motorways and All-Purpose Trunk Roads (APTRs), and operates policies for the control of development accessed from these roads. The advice of the HA applies to all proposals where development would affect the Trunk Road network. Full details of the HA’s policies in respect of development affecting trunk roads and motorways are detailed in DTLR Circular 04/2001 'Control of Development Affecting Trunk Roads and Agreements with Developers under Section 278 of the Highways Act' (1980). It is important that the UDP provides details of the HA’s stance with respect to development, which may affect the Motorway and All-Purpose Trunk Roads. It should be noted that the only road to which this advice applies in Calderdale is the M62. The following are the policies that the HA will follow in the planning process including application for planning permission:-
1. Access to Trunk Roads and Motorways
- Direct access to trunk roads will be rigorously controlled, with no direct access permitted to motorways other than to or from service areas, maintenance compounds and at junctions. There will be a strong presumption against the creation of new accesses to high standard all-purpose trunk roads and to trunk roads with a clear strategic importance. On the less important trunk roads and the majority of the trunk roads in urban areas, this policy may be relaxed provided that road safety is not compromised. In particular the HA would not normally issue a direction of refusal to developments within a 40mph limit.
- The funding of any new or altered access to a trunk road consequent on a development is the responsibility of the developer to be met through a Section 278 Agreement under the Highways Act 1980 (as amended). The access, including its connection with the trunk road should be designed for the traffic flows expected 15 years after the development first opens and should meet normal trunk road standards (but see also section 3 below 'Developer Contributions to Trunk Road Improvements' ). As a statutory consultee on development plans and planning applications that affect a Motorway or Trunk Road, the Highways Agency encourages early consultation on any potential use allocations or development proposals, as stipulated in DTLR Circular 04/2001.
2. Assessment of Wider Network Effects of Development
- Calderdale Council will consult the HA whenever a development is likely to create or attract traffic which will result in a material increase in the volume or material change in the character of traffic entering or leaving a trunk road. In such cases, any necessary Transport Assessment (TA) for the development should be carried out for the opening year and at 15 years after the development first opens.
- The traffic growth forecast used in the TA will reflect local circumstances including factors such as plan assumptions about population and employment growth and network constraints on traffic growth. A range of forecasts (corresponding to low and high national road traffic forecasts) may be required where network implications might involve major investment.
- In assessing the traffic generated by the development itself, account will be taken of measures to encourage use of other modes of travel proposed as part of the planning application including measures to restrict traffic generation, for example, by limiting the provision of private parking.
3. Developer Contributions to Trunk Road Improvements
Where the TA reveals that the development is expected to take junctions or links over their normal operation capacity, or where roads are already over the normal operating capacity, three courses of action are possible:-
- a direction will be given to Calderdale Council to refuse permission for the development;
- a condition will be imposed on the development application requiring that improvements are made to the road network; or
- the application is allowed on the basis that development has no material impact on the functioning of the trunk road.
Whilst the assessment of traffic impact on the trunk road should be made for 15 years after opening, the design of improvement sought through a condition need not necessarily cater fully for traffic growth. In particular the following factors will be taken into account:-
- Network balance; the scale of improvement sought under a condition should not be out of balance with the capacity provided on adjacent sections of the trunk road network, taking account of planned improvements in the road programme;
- Environmental impact: the scale should not be greater than the HA itself would promote given the local circumstances, taking account of the expected impact of an improvement on the environment.
