Flow Traffic Awarded Contract for Hong Kong Journey Time Information System

    SAINT PAUL, Minn., Jan. 22 Image Sensing
Systems, Inc. (ISS) announced today that its wholly owned Asian
subsidiary, Flow Traffic Ltd., has been awarded a contract to supply Autoscope
Solo(R) Pro vehicle detection systems for a new Journey Time Information
System to be implemented on Hong Kong Island.  In its first stage, 20 vehicle
detection systems have been supplied and installation will take place during
the first quarter of 2003.  Extensions to this project are likely to follow.
The project will cover the three cross-harbor tunnels between Hong Kong Island
and the Kowloon peninsula as well as approaching highways on the island side.
The Autoscope Solo Pro will be used to collect various traffic data, including
average traffic speed, in order to calculate the journey time.  This will be
displayed to the Hong Kong drivers via Variable Message Signs.  Other cities
around the world already using Autoscope technology for this particular
application include Atlanta, Georgia in the United States and Seoul in Korea.
    Johan Billow, Managing Director of Flow Traffic Ltd., commented, "This is
our fourth contract for supply of Autoscope in Hong Kong and we are proud to
have been able to satisfy the rigorous demands that Hong Kong authorities have
set up for vehicle detection in respect of reliability and accuracy.
Autoscope maintains a dominant position in Hong Kong and is so far the only
video image processing technology that has been implemented by the Hong Kong
Transport Department for vehicle detection."
