ITS will help us …………
 Assist with incident management and traffic
signal timing
 Isolated or system-wide changes to traffic
signal operations can be made in seconds
 During incidents, traffic signals can be
programmed with special timing, placed into
all red flash, or “stop time” to allow specific
directions of traffic to flow continuously
 Notify staff of issues/conflicts
When an incident
occurs, staff can
provide
information to
first responders
(Fire, EMS, and
police)
Multiple CCTV
provides viewing
from several
angles
