Successful Completion of SBIR Phase 2 on Inductive Loop Signature Technology (Jun 1, 2016)

(May 31, 2016)

CLR Analytics Inc. has successfully completed the USDOT SBIR Phase II, titled  "Transportation System Performance Measurement Using Existing Loop Infrastructure". The final briefing presentation was held in USDOT building located 1200 New Jersey SE. in Washington DC from 12:30 to 4:00 PM on May 31, 2016. About 30 attendees joined the final briefing presentation through the Talk Traffic Webinar. They include representatives from Office of Highway Policy Information and Office of Transportation Management of FHWA, nine state DOTs, including Alaska, Akansas,  Wiscosin, North Carolina, Minnesota, California, Wyoming, Virginia, and West Virginia, researchers from University of California Irvine and University of Akansas, and our team members and partners from International Road Dynamics (IRD), TransSight, and CLR Analytics Inc. The retired Contract Officer Representative (COR), Mr. David Gibson, also joined the webinar and shared his vision and comments.

The webinar was presided by Mr. Steven Jessberger, COR of the project from Office of Highway Policy Information of FHWA. Mr. Jessberger introduced the project and shared his thoughts on what inductive signature tecnology can do for the transportation industry. His short presentation can be downloaded using this link.

Dr. Lianyu Chu and Dr. Cindy Jeng gave a presentation with the following contents: Background, Technology, System design and development, Core algorithms, Applications, System demonstration, Commercialization, and Conclusion and future work. The final briefing presentation can be downloaded using this link. At the end of the presentation, Dr. Chu gave a  live demo of the website developed for the project (, which displayed various point based and section based performance data collected from the two demonstration sites, I-405 NB in California (Freeway) and TH-55 (Arterial) in Minnesota. 

As the end products from the project, CLR offers the following products to the market, including inductive loop signature detector card I-Loop Duo (manufactered by Diamond Traffic Products) and single-loop based vehicle classification (conversion of single-loop counting station to classification site), and high-resolution traffic monitoring and emission monitoring, and etc.

During the presentation, Dr. Andre Tok, a researcher from UC Irvine and the first user of CLR's products, demonstrated how he used CLR's Inductive loop signature detector cards to collect vehicle signature data for the California Truck Data Collection project. UCI has bought 100 I-Loop Duo detector cards for the project. UCI's website is

There were many discussions during the presentation. A short survey at the end of the webinar showed that 50% of the particiapnts are willing to use the technology and another 50% need more information.

For the SBIR phase 2 project, CLR Analytics led the whole project. Diamond Traffic is the main partner providing the detector card hardware solution. Live Traffic Data (LTD) is another partner providing signal operation data for the arterial application. TransSight LLC. provided assistance on commercialization.
