TRICS (Trip Rate Information Computer System) is a database of trip rates for developments used in the United Kingdom for transport planning purposes, specifically to quantify the trip generation of new developments.

The TRICS Consortium describes TRICS as follows:

TRICS is the system that challenges and validates assumptions about the transport impacts of new developments. It is the national system of trip generation analysis, a large database of inbound & outbound transport surveys covering a wide variety of development types.

Release history

The database was established in 1989 by six county councils in South East England (Dorset, East Sussex, Hampshire, Kent, Surrey and West Sussex). It is now maintained by TRICS Consortium Ltd, based in Barnet, London.

TRICS 8 launched in June 2025, overhauling the system, giving it a more modern, simplified look.
