Transportation Assessment Reports

The extent and level of detail covered within our Transport Assessment Reports can vary considerably depending on the type of development being promoted and the capacity of the local highway network to accommodate the additional peak time trip rates generated. Our Scoping Report should however have established the key parameters to be used in delivering our TA report including:

  • The extent of the area to be assessed.
  • The junctions needing to be modelled.
  • The existing traffic survey data which can be used.
  • The new traffic surveys needing to be undertaken.
  • The baseline traffic figures to be used.
  • The growth rates to be adopted to generate the future peak times traffic flow rates.
  • The extent of the available accident data to be included.

With this to hand the TA Report will establish the anticipated level of the additional trips generated by the development and its likely impact on the local highway network. This is a detailed and technically robust document which has to withstand public scrutiny by those wishing to object to the development – and their consultants. Our Transport Assessment reports will include the following:

  • An assessment of the proposals against relevant national and local planning policies and design guidance.
  • A review of the site’s existing uses and planning permissions.
  • Characteristics and capacity of the local highway network.
  • An audit of existing & proposed facilities for pedestrians, cyclists and public transport near to the site.
  • A review of available data, including traffic and personal injury accident data and an assessment of the existing operation of the surrounding highway network.
  • All development commitments or transport infrastructure schemes that may have a bearing on proposals for the site’s development.
  • A multi-modal trip generation assessment for the site using TRICS data.
  • An assessment of the likely proportions of new trips attracted by the development, trips diverted from other locations and linked trips with other facilities available nearby.
  • The potential for the site’s development to encourage sustainable travel patterns.
  • A proposal for an appropriate site access, parking provision and servicing areas.
  • Provision of an assessment of traffic flows for use by appointed air and noise consultants.
  • Identifying the potential for the site’s development to encourage sustainable travel patterns.
  • Liaison with the rest of the design team and provision of swept path analysis to ensure the appropriateness of the site’s access, parking provision and servicing.
  • Construction, validation and analysis of computer models of surrounding highway junctions to allow the traffic impact of the development to be quantified.
  • Identifying any likely significant impacts arising from the site’s development upon the surrounding transport network and designing any mitigating measures, as appropriate.
