Causeway acquired Buchanan Computing in 2024

Welcoming Buchanan Computing
Prior to acquisition, Buchanan Computing was the UK’s leading provider of permanent traffic engineering and highways management solutions – supporting over 90 local authorities with solutions such as ParkMap, SignPlot and SignLoad. We have now fully welcomed Buchanan into the Causeway family, and rebranded. You can continue your journey using the links below.
SignPlot and SignLoad have now been rebranded under the Causeway name as part of our end-to-end suite for traffic sign and road marking design. You can find out more about our offering here.
The UK's leading map-based collision analysis system, AccsMap has now been rebranded as Causeway AccsMap. More information about the solution can be found here.

“The acquisition of Buchanan Computing reinforces our commitment to delivering a fully integrated, end-to-end solution for Highways Authorities and Contractors, enabling them to seamlessly plan, monitor, and communicate the management and maintenance of their infrastructure assets while ensuring full compliance with legislation. By bringing our vision to life, we empower local authorities to operate more efficiently, maximising their limited budget and resources.”
Phil Brown, Executive Chairman of Causeway
“For several years we have worked closely with Causeway, providing added value to mutual clients by providing links and integrations between our respective products. I am confident that Causeway is a great home in which to continue to advance the ethos of providing market leading, time-saving products, together with excellent support, training, and consultancy services.”

The acquisition of Buchanan Computing builds upon Causeway’s vision of digitalising construction, maintenance, and traffic management processes by connecting Causeway one.network with Buchanan’s ParkMap, to create the UK’s first unified platform for Digital Traffic Regulation Orders (D-TROs). This integration will benefit traffic authorities who will gain a crucial way to digitise all their permanent and temporary traffic regulation orders in a single platform, improving public consultation, reducing duplication and error, and boosting efficiency with a unified view.
