Trip generation assessment and analysis

This tool provides promoters and designers with reference to a method and software capable of providing trip generation assessment and analysis. It assists in providing an understanding of the impacts on trip generation of particular land uses / development activity / commercial activity at/or in the proximity of interchanges.

TRICS® is the system that challenges and validates assumptions about the transport impacts from new developments. It is the national standard system of trip generation and analysis in the UK and Ireland, and is used as an integral and essential part of the Transport Assessment process.

It is a database system that allows its users to establish potential levels of trip generation for a wide range of development and location scenarios, and is widely used as part of the planning application process by both developer consultants and local authorities.

Good practice

Mainly used across the UK and Ireland as part of the transport assessment process. Tool reviewed as part of the NODES demonstration site at Reading station. It was noted that the tool is more relevant to the developments surrounding the interchange and the impacts of there trip generation and subsequent implications for the interchange. Reading Borough Council noted in testing the tool that; “TRICS is accepted by both developers and local government as a valuable tool, although its extensive set of variables makes it a potential source of conflict. TRICS helps the planning process proceed to an agreeable conclusion which allows developments to take place and mitigation from their effects to be provided.”


Potential interchange performance improvement

Could help inform transport network planning and potential capacity required at interchanges related to trip generation for developments where users may use the interchange as part of their journey to them.

Could influence design assumptions for interchanges relative to the understanding of trip generation where other commercial activities either linked due to proximity or integrated into its design.



  • Training requirements
  • Software licenses
  • Appropriate technical resources required
