International Road Dynamics to supply equipment for Hawaii traffic data collection project


Canadian highway traffic management technology company International Road Dynamics (IRD) has been awarded a five-year US$8.1m contract to supply traffic data collection and services to the Hawaii Department of Transportation (HDOT).

Under the new contract IRD will supply HDOT with Continuous Traffic Monitoring (CTM) data collection equipment and services for deployment across the multiple islands that form the state. The CTM systems will collect traffic volume, speed, vehicle classification, and weight data to support the HDOT’s continuous traffic monitoring program on state highways. This agreement covers the supply, operation and maintenance of the CTM systems, as well as data reporting, hosting and management.

IRD has had a successful working relationship with HDOT going back to its original truck Weigh-in-Motion (WIM) station that was deployed on the Sand Island Parkway in 1986. Today there are 81 permanent traffic monitoring sites that are supported under this contract on six of the eight major Hawaiian Islands (Oahu, Maui, Hawaii, Lanai, Molokai, and Kauai). Additional site locations are expected to be added during the term of the project.

Over the years, IRD has provided and maintained WIM and Continuous Vehicle Data Collection (CVDC) equipment and services to HDOT, as well as provision for real-time display via web access throughout Oahu, Maui, Hawaii, and Kauai. There are 30 permanent HDOT WIM and two CVDC sites that provide volume classification and weight data necessary to assist the agency in their future pavement planning and design.

In addition, IRD has installed and maintained 35 permanent Enhanced Vehicle Collection (EVC) sites on five islands. The company provided web-based, real-time traffic information ASP (Application Service Provider) services, with IRD collecting and hosting the data, as well as providing HDOT with proprietary and secure access to the information over the internet.

The traffic monitoring systems are used for assessing pavement damage caused by heavy vehicles. Data from the systems will influence the development of the state’s commercial vehicle enforcement plans. This data will also be used as a means for providing estimates for noise studies and identifying changes in highway travel patterns and related factors. IRD’s VI2M (Vehicle Information in Motion) cloud-based data collection, reporting and analytics service is a key component of the new contract and will provide the state with a complete picture of activity across all traffic monitoring sites.

“We are proud of our record in Hawaii and are committed to ensuring the success of HDOT’s Highways Planning Data Collection and Motor Vehicle Enforcement Programs,” commented Randy Hanson, IRD’s president and chief executive officer.

“This project shows the importance of continually advancing our technology to anticipate our customer’s future needs. Relationships such as we have with HDOT provide a solid base to support new developments and offerings to all of our transportation industry partners.”
