Traffic and Transport Assessments

Traffic and Transport Assessments (TTAs) seek to assess the impact of a development proposal on the surrounding road network. Key considerations include traffic impacts, safe and efficient site access and egress, and the impacts of active travel and sustainable transport on the surrounding transport network. TTAs are undertaken in accordance with Transport Infrastructure Ireland’s Traffic and Transport Assessment Guidelines to progress a development through the planning process. TTAs are necessary for a range of commercial, retail, residential (including strategic housing developments or SHDs), and Environmental Impact Assessment Report (EIAR) traffic and transport chapters.

Key components of this service include, as necessary:

  • Local authority pre-planning scoping engagement
  • Site assessments
  • Quality audits and road safety audits
  • Traffic survey data specification, procurement, collection and analysis
  • Traffic and transport modelling
  • Parking accumulation analysis and parking impact assessments
  • Strategic housing development (SHD) pre-application meeting representation
  • Expert witness representation at oral hearings
  • Construction Traffic Management Planning (CTMP)
  • Third-party advice and traffic/ transport submissions
