According to the 2004 Customer Service Tracking
Survey, traffic congestion and associated delay
is a major public concern. As population increases,
intensification of land use occurs which results
in even greater congestion. With increased congestion
comes air quality problems and added fuel consumption.
Improving the efficiency of the existing highway
system through the implementation of advanced technologies,
with the coordinated efforts of various public
agencies and the private sector, is one of the
best ways to alleviate congestion. One such method
of optimizing the existing highway system is through
implementation of the Transcore PCTCS Traffic CSystem.
Based on the successful performance of the Downtown
Central System the Transcore PCTCS is being implemented
Citywide. To date, our traffic control network
has been implemented at 300 of City Of Sacramento's
700 signalized intersections, with many more intersections
under construction this year. We have received
funding commitments, which will enable Traffic
Engineering to connect to up to 100 more traffic
controlled intersections.
PCTCS is a computer-based
traffic signal control system that monitors traffic
conditions and system performance, selects appropriate
signal timing (control) strategies, and performs
equipment diagnostics and alert functions. Sensors
in the street detect the passage of vehicles, vehicle
speed, and the level of congestion. This information
is received on a second-by-second (real-time)
basis and is analyzed at the Traffic Operations
Center, located across from City Hall. If required,
the signal timing can be changed by the operator
using communication lines that connect the PCTCS
Center with each traffic signal. To supplement
the information from electronic detectors, closed-circuit
television (CCTV) surveillance equipment has been
and continues to be installed at critical locations
throughout the City. The Department has installed
CCTV cameras at 18 locations and new sites are
being added.
