Utilising Government Guidance such as the National Planning Policy Framework (NPPF), the National Planning Policy Guidance (NPPG) and Guidance on Transport Assessment, we are able to produce reports addressing the traffic and transportation issues for developments in a range of sectors, such as residential, employment, retail and leisure, and for any scale of development. Collectively, our staff benefit from a whole spectrum of experience spanning the last 30 years in both consultancy and local authority positions.
Keeping up to date with Local and National Government policy while maintaining good relationships with Local Authorities, we are able to offer sound advice to our clients at every stage of the planning process.
Transport Assessments (TA)
Most major planning applications require a Transport Assessment to be prepared and submitted as supporting documentation. A Transport Assessment will usually cover a detailed assessment of trip generation/attraction together with an appraisal of the impact of traffic on the local highway network. We can organise traffic surveys and vehicle speed surveys to provide accurate and detailed information to base our assessments upon. The nationally recognised TRICS database is used to establish the multi-modal trip rates of a wide range of development types. Traffic distribution and traffic assignment is calculated using a gravity model, which can be based on information extracted from National Statistics/latest census data. Where necessary we make use of the most up to date traffic modelling software such as Transyt, LINSIG and Junctions 8 (ARCADY & PICADY). Where a requirement for a link or junction capacity improvements is found to be essential, economic and efficient designs can be prepared to support your proposals.
An accessibility assessment will also be undertaken, detailing the available choices for travel mode to and from a development, including on foot, by cycle and by public transport. A TA will usually require discussions with the highway authority before and during the application process, in order to agree and negotiate the scope, contents and conclusions of the assessment.
Transport Statements (TS)
For smaller developments that generate lower levels of traffic, a Transport Statement may be required to support the planning application. This will cover a similar range of transportation aspects as a Transport Assessment, though generally in less detail. A Transport Statement will typically only consider the impact of traffic associated with the development on the site access, reducing the overall size of study area.
Although many minor developments will fall below the thresholds for either a Transport Assessment or Statement, they will often require a Highway Statement to address a specific issue relating to the site. This could be as a result of local car parking problems, visibility constraints, or simply due to local concerns for which a Highway Statement may help to assure local residents.
Some major planning applications can be required to be supported by an Environmental Statement (formerly known as an Environmental Impact Assessment or EIA), covering a variety of disciplines such as Air Quality, Bio-diversity and Socio-economics. One of the aspects that should be included is Transport and its environmental impact on the surrounding area.
SCP can prepare the Transport chapter, covering the construction, operational and decommissioning (where relevant) stages of a development. The report addresses impacts on severance, congestion, road safety and pedestrians.
Noise/Air Quality Data
SCP regularly provide traffic flow data tailored to specific sites for Noise and Air Quality Consultants to use. We can provide Annual Average Daily Traffic (AADT) flows for Air Quality Assessments and Annual Average Weekday Traffic (AAWT) flows for Noise Assessments. See our FAQ section for more information on these flows. If necessary, we can recommend noise/air quality consultants.
Feasibility Appraisals/Site Appraisal
SCP provides highway and transportation advice on schemes at the feasibility stage, allowing land owners or prospective purchasers to understand the constraints of a site before preparing detailed consultant reports. We can advise on the sustainability of a site, likely access requirements, carry out preliminary flood risk assessments and prepare preliminary drawings to demonstrate the ability to achieve a suitable access.
Swept Path Assessments
As part of any development layout the ability for appropriate vehicles to manoeuvre is a key requirement. We can offer swept path assessments for any scheme with an extensive library of vehicles as well as having the ability to assess bespoke vehicles. Our preliminary and detailed design input to schemes includes checking of swept paths to ensure that our designs will accommodate vehicles satisfactorily.
Car Parking Assessments
Customer parking is a valuable asset to clients and therefore maximising its use is critical to a business operation. Using traffic surveys, we can undertake an assessment of a car park to identify any abuse by non-customers and advise on a range of parking management initiatives to address capacity issues. Car parking assessments are also useful where an existing business wants to expand without providing additional car parking. We can assist with a car parking justification study. We can also assist in preparing plans to show the most efficient car park layout design possible.
For major developments, public consultation is a key aspect of progressing the design of a scheme towards meeting the requirements of a planning application. SCP can assist in preparing presentation material as well as attending public exhibitions or speaking at a public meeting.
