Liverpool City Council has recommitted to CausewayOne Network and adopted Causeway ParkMap, choosing Causeway over a competing provider to digitise its traffic regulation orders ahead of the DfT's upcoming D-TRO (digital traffic regulation order) requirements.
The council, one of the largest metropolitan authorities on Merseyside, has used CausewayOne Network's Traffic Management module for more than seven years. When it came time to address D-TRO compliance for both temporary and permanent traffic orders, Liverpool evaluated the market and selected Causeway as the provider that could deliver a proven, working solution covering both TRO types.
A mixed starting point for TRO data
Previously, Liverpool had no software for managing permanent traffic regulation orders. The council's TRO records sit in three different states across the city. The city centre is fully digitised, following a comprehensive LiDAR survey completed in the last year. The north of the city is partially digital. The south remains largely paper-based, with records still held in filing cabinets.
That mixed picture is exactly why the combination of Causeway ParkMap and Causeway's TRO consultancy services matters. Liverpool doesn't need all its data clean and complete before the system goes live. The council can start digitising new orders immediately while working through the historical backlog at a pace that fits its resources.
Managing temporary and permanent TROs through one provider
With CausewayOne Network and Causeway ParkMap now in place, Liverpool can manage both temporary and permanent traffic regulation orders through a single provider for the first time.
-
Meet D-TRO requirements for all TRO types ahead of the DfT's requirements taking effect. The TTRO Hub covers temporary orders. Causeway ParkMap covers permanent and experimental orders. Both are D-TRO compliant, so Liverpool can submit digitised data directly to the DfT.
-
See the full picture of what's happening on the road in a single view. Permanent TRO geometries from Causeway ParkMap now appear as a live layer within the CausewayOne Network map, alongside 90+ other operational datasets covering streetworks, permits, Section 58 restrictions, public transport and events.
Coordination teams no longer need to switch between systems when reviewing a permit or planning a closure. -
Digitise permanent TROs for the first time with a full audit trail. Causeway ParkMap gives Liverpool a structured system for creating, managing and maintaining permanent orders, with schedule generation, map schedules and moving traffic order support built in.
What's next
Causeway ParkMap is being provisioned now. Once live, Liverpool will begin digitising new permanent TROs straight away to meet the DfT's D-TRO requirements.
The larger job of bringing the council's full historical archive into Causeway ParkMap, particularly the paper-based records in the south of the city, will be supported by Causeway's TRO consultancy team. That team works with authorities through a structured, phased approach covering data assessment, digitisation, data capture and migration, and workflow integration, so Liverpool can close the gap at a pace that matches its resources.
As CausewayOne Network and Causeway ParkMap continue to integrate within the CausewayOne platform, Liverpool's investment will only become more valuable.
