Intelligent transportation systems are used for a wide variety of applications
from photographic red light violations, to regulating traffic flow via
ramp metering, providing emergency messaging to drivers, disseminating
traffic flow data to the public via the Internet, and even emissions monitoring.
While these intelligent
transportation and traffic management systems are implemented using a
broad range of hardware and software platforms, they all have one thing
in common--a need for a large number of RS-232, RS-422, or RS-485 serial
ports to connect essential devices such as:
- Traffic
Signal Controllers
- Camera Pan-Tilt-Zoom Controls
- Video
MPEG Encoders/Decoders
- Loop
Detectors
- Ramp
Meters
- Queue
Detectors
- Variable
Message Signs
- Lane
Control Signals
- Pavement
Sensors
- Vehicle
Detectors
- Side-scan
Radar
- Smart

Quatech
device servers
are the most reliable
way to enhance performance in
Intelligent Transportation Systems.

Traditionally these intelligent transportation systems were installed
using legacy serial equipment and proprietary software applications. However,
new standards imposed by the National Transportation Communications for
Intelligent Transportation Systems Protocol (NTCIP) require that all authorized
jurisdictions be able to gain access to all Traffic Management Centers
and Traffic Control agencies' systems, and that support be provided for
multiple vendor systems. Device networking technology provides a fast
and easy way to meet the accessibility standards required by NTCIP without
changes to your agency's software applications. In addition, the device
servers enhance performance of serial-based equipment by permitting them
to be remotely accessed for monitoring and maintenance from any computer
on a wired or wireless network via Local or Wide Area Networks--including
the fiber lines already in place along most major roadways. Not only does
this provide instant accessibility, it also permits a constant stream
of real-time data to be collected, analyzed, and utilized for active traffic
management and for providing the public with accurate congestion information
so that they can pick the best travel routes.
What is the most reliable way to enhance performance for intelligent
transportation systems? Quatech device
servers lead the industry with the most powerful processor and the
lowest latency available for device networking solutions--a key feature
for traffic management systems with intensive polling requirements. Easy to install and configure, our device networking product line is integrator
friendly, offering easy to install and configure wired and wireless options
with one to eight ports. Designed for interagency and intra-agency cooperation,
Quatech device servers permit various computers running different operating
systems to access the device server simultaneously. And, since Quatech
device servers function as standard COM ports, any equipment can be network-enabled
without alteration to custom software applications.
