JCT Consultancy was established in 1989 to promote traffic signal training and consultancy alongside software development. Since release by the original company in 1985, the JCT LinSig software has been the UK industry standard for traffic signal assessment and design. Over this period JCT has built a reputation for innovation in traffic signal design, traffic modelling and network control, with signalled roundabouts being a particular area of expertise.
