Dynamic Mobile Sensing Platforms
Advances dynamic mobile sensing to transform how roads, bridges, and railways are monitored, enabling smarter, faster, and more resilient transport infrastructure worldwide!
What We Do
We advance mobile sensing technologies to enhance the monitoring, safety, and resilience of transport infrastructure. By integrating dynamic mobile sensing with advanced data analytics and intelligent decision tools, our technology enables cost-effective and scalable inspections of roads, bridges, and railways.
What We Have
Bridge Inspection
A robotic mobile sensing platform, equipped with accelerometers and GNSS modules, autonomously captures bridge vibration data to assess structural health. Successfully tested on more than ten bridges in Singapore, this robot represents a breakthrough in fast and automated vibration-based bridge inspection.
Road Inspection
A compact sensor box attached to bicycles measures road roughness through vibration and GPS data. After real-world validation in Zurich and Singapore, the results demonstrated how everyday mobility can be leveraged to monitor urban road quality, ensuring safer and smoother rides across networks. The sensor box can also be deployed on cars and trains for roadway or railway inspection.
Turning Data into Action
A virtual analytics platform integrates mobile sensing data, mapping infrastructure health and enabling decision-makers to visualize, prioritize, and plan maintenance efficiently, with the aid of AI-based algorithms.
What You Get
