Road network
Corridor intelligence
Deviation and leak-rate patterns by region and corridor, built from simulated session volume.
Simulated real-world data being used for demonstration purposes

Evidence base
Methodology behind the network view
Regional deviation, leak rates and corridor patterns are simulated here, but the quantities being modelled and the way they are aggregated follow established measurement practice.
Deviation from an approved value, not from an average
Every deviation figure is measured against the vehicle's approved table value, which is the only defensible reference.2025
Leak rate as a maintained quantity
Continuous permeation loss means a per-vehicle loss rate is estimable from repeat sessions and is the right unit for a network signal.2009

Coverage is the product
One machine is a convenience. A network is infrastructure: enough density that a pre-journey check is never a detour, and enough sample that the data means something.

Placement follows journeys, not footfall. Motorway service areas catch laden long-distance trips, urban forecourts catch commuter fleets, and depot installations catch commercial duty cycles before the first mile.
- Motorway and trunk-road services for pre-journey laden traffic
- High-volume urban forecourts for repeat consumer sessions
- Depot and last-mile hubs for van and LCV fleets
- Ferry, tunnel and holiday corridors for seasonal peaks
Phased deployment
Step by step
Pilot cluster
Phase 1Eight units in a single region with one forecourt partner, proving throughput, uptime and session economics.
Regional density
Phase 2Sixty units across two regions, enough sample for the first credible condition index.
Corridor coverage
Phase 3Motorway and trunk-road corridors linked so a long journey is never more than a few minutes from a unit.
National standard
Phase 4Coverage sufficient for pre-journey checking to be an expectation rather than an option.
