TRICS® is the system that challenges and validates assumptions about the transport impacts of new developments. It is the UK and Ireland’s national system of trip generation analysis, containing nearly 6,000 directional transport surveys at over 100 types of development.

TRICS® was founded and is owned by 6 County Councils in the south of England, collectively the TRICS® Consortium. However, its annual collection programme covers the whole of the UK and Ireland, across 17 defined regions. This is reflected in the national spread of member organizations across each of these regions, which we know as the TRICS® Community.

This is the website for that community, as well as being a resource for anyone interested in the field of trip generation analysis. Please have a look around – we look forward to receiving your feedback.
