JCT Consultancy Ltd

What JCT Consultancy Ltd does

JCT Consultancy Ltd is a privately held UK engineering consultancy and software developer, founded in the 1980s and headquartered in Lincoln, England. The firm specializes in traffic signal design and modelling, operating across three integrated lines: proprietary software products (centred on the LinSig suite), IHE-accredited training courses, and specialist traffic signal consultancy. Its primary customers are UK local authorities, traffic engineering consultants, central government, and traffic signal engineers responsible for junction design, network modelling, and transport assessments supporting development planning.

The firm's core technology is LinSig, an in-house-developed lane-based traffic signal modelling software that has been described as the UK industry standard since 1985. The product portfolio includes LinSig 3 (current flagship with network modelling, matrix estimation, and SCATS controller support), LinSig 2 (legacy), plus add-on modules (quickGreen, TranEd, FlowRound, LinSat) and the JCT TrafficTools Android mobile app for on-site data collection. Software is developed by in-house traffic engineers, giving the firm an unusual dual capability in domain engineering and software production. Certification under ISO 9001 and IHE training accreditation support quality positioning.

JCT earns revenue through a mix of one-time software licenses, recurring annual software support agreements, per-delegate training course fees (running approximately 40 courses per year across the UK and selected international venues), and specialist consultancy engagements. Distribution is direct via the company website, with training delivered both online and at UK physical venues. The firm has no external institutional investment, no parent company, and operates with a small 1–10 person team serving a UK-centred customer base with selective international reach into Australia, New Zealand, and Ireland.

Expansion highlights5 records

Broad incumbents

• Yunex Traffic: Global traffic management and signal systems vendor (formerly Siemens Intelligent Traffic Systems). Overlaps with JCT's domain but operates as a broad incumbent delivering end-to-end hardware, controllers (MOVA, SCOOT), and software to road authorities.
• SWARCO: Austrian-headquartered traffic solutions provider offering signals, signage, parking, and traffic management software. Comparable as a broader incumbent in the same end-customer ecosystem (road authorities) but with a much wider product portfolio than JCT's software-only focus.
• PTV Group: German transport-planning software vendor behind VISSIM, VISUM, and other traffic/transport modelling tools. Overlaps with JCT in junction and network modelling but operates at much broader scope, serving highways, public transport, and logistics use cases globally.
• Kapsch TrafficCom: Global intelligent transportation systems provider selling tolling, traffic management, and connected vehicle solutions. Overlaps in the broader traffic-engineering ecosystem and competes for the same road-authority budgets but at significantly larger scale.

Direct peers

• TRL Software: UK-based transport research and software spinout offering tools for road safety, asset management, and traffic engineering. Comparable as a UK-headquartered specialist software + consultancy vendor serving local authorities and central government with overlapping customer base to JCT.
• Sidra Solutions: Australian developer of SIDRA Intersection and SIDRA Network, the leading signalised intersection and roundabout modelling software in Australia/NZ. Directly comparable as a niche traffic-modelling software vendor with similar products (LinSig vs SIDRA) competing for the same engineering workflow.
• Transoft Solutions: Canadian transportation engineering CAD and design software developer (e.g., AutoTURN, Torus, SignCAD). Comparable as a specialist vendor selling licensed design software to traffic and highway engineers, with a similar perpetual-license + support model.

Regional players

• McTrans Center (University of Florida): US-based distributor of highway capacity software (HCS), CORSIM, and TRANSYT-7F to US state DOTs and consultants. Comparable as a specialist transport-software distributor but primarily serves the US market rather than competing head-to-head with JCT in the UK.
