How it started
History
Dr. Art Bergan, a world-renowned civil engineer in the transportation field, established IRD in the late 1970s. IRD's first product was weigh-in-motion scales.
By the mid-1990s, IRD had become established as a major player in the international Commercial Vehicle Operations (CVO) market. In 1995 IRD installed the world's first dynamic truck speed warning system for the Colorado Department of Transportation. Developed for the freeway west of the Eisenhower tunnel, the system incorporated sensors and an automatic scale to weigh and classify trucks. An algorithm was used to estimate the maximum safe speed for the vehicle as it approached the descent into the canyon. The speed was then displayed on a variable message sign accompanied by flashing lights.
IRD South Asia Private Ltd. is a wholly owned subsidiary of IRD that was established in 2000 and specializes in toll collection systems. As of 2011, IRDSA employs 160 people and has a 54-per-cent share of India's toll business. Company offerings include manual systems, smart card systems, and transponder systems. These systems include proprietary weigh-in-motion technology designed to help concessionaires reduce road-damage and revenue losses. IRDSA also manages data-collection services in cooperation with the National Highways Authority of India (NHAI).
IRD acquired the Germany-based PAT Traffic in 2003. By 2009, IRD had installed 10,000 IRD-PAT Bending Plate Scale weigh-in-motion systems.
In 2007, IRD acquired a 50% interest in Xuzhou-PAT Control Technologies Limited (XCPT), an Intelligent Transportation Systems company located in Xuzhou, Jiangsu, China. XPCT had distributed IRD's products in China since 2003. IRD's joint venture in China provides toll road systems, traffic monitoring, and maintenance.
