Case Study: Tay Road Bridge, Dundee

• Client: Dundee City Council & Tay Road Bridge Joint Board

• Location: Dundee, Scotland

• Theme: Smart Roads • Infrastructure Analytics • LiDAR + CiiM

• Tech: 3D LiDAR sensors, CiiM (sensor-agnostic), cloud dashboards

Overview

The Tay Road Bridge is a critical corridor connecting Fife and Dundee, carrying over 27,000 vehicles daily alongside pedestrians and cyclists. The existing 32-camera system monitored activity, but decision-making was hampered by slow, intrusive, and limited data sources. Digiflec deployed CiiM, our Connected Intelligent Infrastructure Monitoring platform, to deliver real-time, non-intrusive insights that inform maintenance and operations.

The Challenge

• Delayed insight: Traffic counts from in-road loops were retrieved quarterly, delaying interventions.
• Intrusive maintenance: Loop installation/maintenance disrupted operations and risked road integrity.
• Limited wear insight: Existing tech struggled to differentiate vehicle types/loads for targeted maintenance.

The Solution

Digiflec installed 3D LiDAR and configured CiiM to turn raw point-cloud data into live operational intelligence:

• Real-time monitoring: Continuous flow tracking replaces quarterly snapshots.
• Non-intrusive setup: Sensors mount without cutting the carriageway, preserving structural integrity.
• Enhanced insights: CiiM classifies traffic patterns, vehicle types and load distribution for smarter planning.

Outcomes & Impact

• Better maintenance planning: Use wear/usage evidence to prioritise repairs before they escalate.
• Smarter spending: Allocate budgets based on real impact by vehicle class and intensity.
• Greater efficiency: Live dashboards speed up responses and minimise disruption.

Looking ahead, CiiM’s roadmap also includes features to detect distress among bridge users to further enhance safety and response.
