International Road Dynamics has been awarded two contracts for approximately Can$2.4 million for virtual Weigh in Motion (VWiM) systems for the Illinois State Toll Highway Authority (Illinois Tollway).
Three new VWiM systems will be installed at two sites on I-294 and I-88 for the Illinois State Police to monitor commercial vehicles for weight, size and tyre violations.
IRD says each site consists of WiM sensors, iSINC WiM controllers, IP cameras, over-height detection sensors and the Tire Anomaly and Classification System (TACSTM), which screens trucks for flat, missing or mismatched tyres.
The TACS installations are the largest to date for IRD, with six lanes of TACS in one direction on I-294 northbound and three lanes in each direction on I-88 (eastbound/westbound).
When completed, these sites will expand IRD’s footprint of VWiM systems on the Illinois Tollway network from two to five.
IRD’s Virtual Weigh Station (VWS) web-based software will provide law enforcement officers with remote access to real-time data, including vehicle images, vehicle record data, and reporting.
The TACS systems will be integrated with the VWS to display the locations of the tyre anomalies on vehicle records, and IRD will also provide training.
IRD president and CEO Rish Malhotra says: “Our technology has been proven in the previous VWiM deployments, and we are confident that the Illinois Tollway will see the same benefits in terms of pavement preservation, improved safety, reduced congestion, and lower costs."
The scope of the tyre safety screening component of the system is the largest we’ve booked to date and is an indication of the value the system provides and the confidence that experienced users have in the accuracy of TACS.”
IRD’s Construction Services unit will oversee the electrical and construction work, installing new conduits, power cables, junction boxes, and electric handholes, and overseeing site preparation.
