The IDI 2500 is part of a family of pre-packaged ITS Controllers and is specifically
designed to detect and alarm during congestion events. The IDI 2500 is
particularly suitable for work zone safety, where congestion at a work zone taper
can cause unsafe conditions. In fact, it is ideal for any traffic situation where a
back-up can compromise safety - motorists approaching blind corners, short off-
ramps and similar unsafe environments can now be alerted to slow or stopped
traffic ahead.
A highly flexible configuration scheme is supplied as standard. Congestion
thresholds (speed and occupancy) can be set per lane, with variable hysteresis.
Interfaces to the popular makes of radar sensors are provided, and device drivers
can be added for any make of traffic sensor. Internally, all threshold calculation is
performed using the NTCIP standards, which makes this device truly independent
of radar or sign manufacturer.
Powerful communication options are available to meet any application, including
spread spectrum radio connection to the radar device. An optional comprehensive
statistics package is available, to upload traffic and congestion alarm data into an
Access database. Data from this database may be filtered, printed in reports,
graphed or exported to Excel for further analysis.
Intelligent Devices, Inc is committed to providing a line of powerful and easy-to-use
products for the Intelligent Transportation Industry.
