Recently, ISS reported the seventh consecutive year of record financial
results; including a fourth quarter of 2008 with revenue and earnings the
highest ever in the company's history. ISS' detection technologies extend the
life and enhance the value of the transportation infrastructure by making it
smarter, efficient and responsive to real-time traffic. As communities
continue to be plagued by high traffic congestion, transportation managers are
seeking modern, cost effective and low maintenance solutions to improve
traffic flow and safety. "We're turning the world green, one traffic light at
a time," stated Kenneth S. Shain, VP Sales and Marketing for the company.

ISS was founded in 1984 and introduced the world's first commercial video
vehicle detection product in 1991. After carving out a unique niche in the
Intelligent Transportation Systems (ITS) industry, the company went public in
1995. ISS has resisted the recent market undertow, reporting healthy
financial results while it continues to create economic value and maintain its
leadership role in pioneering new technologies aimed at reducing congestion
and traffic's environmental impact.
