Trevor  first came across MX (or MOSS as it was then) in 1977 when working as a graduate engineer with East Sussex County Council. He was asked to evaluate MOSS against the current product at that time, which was BIPS. MOSS was first used in earnest on the Bexhill Old Town Bypass, which had two complex traffic signal junctions which BIPS could not model successfully. He helped develop the expansion of MOSS throughout the highways department before leaving in 1988. He spent the next 10½ years working at MOSS Systems Ltd/Infrasoft first as a trainer, then on the helpdesk and finally as part of the development team working on the MX project. Since leaving Infrasoft in 1998 he has been working as a freelance consultant, selling his MX and highway design knowledge to a variety of companies in the South East, including TPS Consult, Owen Williams, Capita Symonds, Peter Brett Associates, Hyder Consulting and Jacobs. Trevor has worked on a variety of highway projects, including tender and detail designs for schemes in the UK, Ireland and the Middle East, to the illustrative design for the M25 widening between Junctions 16 to 27.
