Intelligent Transportation System Scenario and Challenges
Video Detection is an effective tool for traffic
control and management. Video cameras provide immediate fullmotion
feedback as traffic hotspots unfold, as well as offer better information
for emergency vehicles, pedestrian and vehicular safety, public security,
incident management and other control and management functions that
are the outgrowth of increasingly congested traffic conditions.
Ethernet is emerging as the protocol of choice for incorporating
video cameras at traffic intersections.
The challenges for the Traffic Management Center (TMC)
when incorporating these Ethernet technologies
such as Video Detection to existing Intelligent Transportation Systems
is twofold:
- how to avoid making costly investments in replacements
of existing traffic controllers
- how to maintain the use of existing Transportation Management
Control Application Software
Solution
 Several solutions exist that allow you to add Video Detection
to an existing ITS however they involve costly equipment replacement,
costly installation of separate Ethernet over fiber lines and the possibility
of lengthy construction timelines.
Perle has a solution that allows for continued use of existing applications
and equipment, and the prevention of laying separate Ethernet over
fiber lines.
A local municipality in the northeastern United States recently realized
the benefits of Perle’s cost saving solution. The municipality
installed new Video Detection at intersections and IP enabled their
serial RS232 based ITS equipment with Perle’s IOLAN
Device Servers.
They removed the older serial to fiber converters and replaced them
with a high performance, cost effective 8 port IOLAN STS in the TMC
and an IOLAN 1 port unit at each intersection site. Now the video,
Ethernet and serial traffic controllers are consolidated across the
same Ethernet fiber connection.
