TechnologyFrom a central location, the traffic management center (TMC),authorities are able to monitortraffic and weather conditions
from CCTV cameras installed at various locations in and
around the city. Information gathered at the TMC is shared
with other agencies and cities in a region to manage traffic
more effectively. The traveling public is informed about
potential problem areas by dynamic message signs and
hazard advisory radio systems along the roadway and
emergency service response times are reduced by knowing
more about the location and conditions surrounding an
incident requiring emergency service.
ChallengesNetwork equipment are installed in an outdoor cabinets closeby the roadways. Regular network products simply cannot
handle outdoor temperature and harsh conditions such as
unpredictable humidity as well as electrical and electo-
magnetic interference. Equipment must be mounted in field
cabinets, with limited space and operate in the harsh outdoor
environment without fans.
Placentia, CA USA anyone who lives in a major metropolitan area and commutes to work knows the roadways are extremely
crowded and getting more so every day, during morning and evening commute time. While the obvious solution is to build more
and larger roadways to accommodate more automobiles, many localities have recognized that there are technological solutions
that can complement or supplement the traditional project of adding or widening roadways. Another solution is to use Advanced
Technology Management Systems to monitor and manage traffic congestion more efficiently. Traffic management systems, today,
include traffic light controllers with inputs from various types of vehicle detectors (such as video, radar and magnetic), video
surveillance systems, dynamic message signs and other systems to measure traffic flow and inform the driving public about hot
spots. These systems are designed to allow traffic engineers and emergency personnel to monitor traffic flowand predict trouble
spots before they become trouble spots.
Traffic management systems, today, include traffic light controllers, video surveillance,
dynamic message signs and other systems to measure traffic flow and congestion and
inform the driving public about hot spots.
SolutionsEtherWANs products are designed for hardened and heavy dutyapplications suitable for outdooror extreme environments. The
SE6101 converters traffic light signals from serial mode to Ethernet.
The EX71000 is featured with EtherWANs proprietary -ring
supporting recovery time less than 15ms. The EX71000 switches
form a ring architecture with the EX77000 sitting closer to a
centralized traffic management office. These switches create a
redundant network system that is critical to traffic control city wide.
