About the company:
International Road Dynamics Inc. (IRD) is a multi-disciplinary Intelligent Transportation Systems (ITS) company. Established in 1980 by Dr. Art Bergen, Professor of Civil Engineering, University of Saskatchewan. IRD is recognized as a world leader in the design, development, and deployment of customized technology. Today, IRD offers a growing portfolio of services and solutions, bringing new technology to transportation planning, operations, and management of transportation. ITS is the use of advanced technology to enhance the operation of highway systems and save lives, time, money, energy, and the environment.
When established, IRD introduced one of the first commercially available sensors developed specifically as a weigh-in-motion technology. IRD continues to develop and adopt the use of advanced technology, including cloud computing, data analytics, edge computing, distributed systems, and innovations to in-road sensor technology to create our portfolio of products and services.
Recent work includes VectorSense in-road sensor technology, which utilizes time domain reflectometry technology to measure tire contact at highway speeds to derive a variety of vehicle characteristics. IRD is currently researching and developing non-intrusive vision AI technology for the ITS industry.
Describe the project.:
International Road Dynamics is a company focused on roadway safety and infrastructure protection, working with governments and private industry worldwide to collect data and enable them to make better decisions. We are looking for an individual who wants to make a difference in road safety and road design through research and data analytics with an eye toward academic publications.
Recent estimations indicate that there are over 50,000 structurally deficient bridges in need of urgent repairs in North America alone. This equates to almost 8% of total structures that pose a significant safety risk if action is not taken. Repair of these structures is not kept up to the rate of deterioration, this will lead to a greater frequency of catastrophic failures, closed or posted bridges, and disruption in traffic management. This brings the absolute need to deploy structural health monitoring systems to provide actionable data for planning, monitoring, and prediction of these aging structures.
Focusing on one of the most common bridge types, a simply supported concrete girder and deck structure. The proposed project is to conduct a literature review and develop a basic model to indicate structural changes based on deflection measurements of the girder. The model development shall consist of aspects accounting for but not limited to, current structural state/age, and vehicle loading (weight, count, and vehicle class). With inputs from the sensor systems, the model is intended to indicate a rate of change in structural performance, looking for accelerated degradation possibly indicating a problem. It is not necessarily intended to give an absolute indication of structural health.
