This
market package provides the communications and roadside equipment to support
ramp control, lane controls, and interchange control for freeways. Coordination
and integration of ramp meters are included as part of this market package.
This package is consistent with typical urban traffic freeway control
systems. This package incorporates the instrumentation included in the
Network Surveillance Market Package to support freeway monitoring and
adaptive strategies as an option. This market package also includes the
capability to utilize surveillance information for detection of incidents.
Typically, the processing would be performed at a traffic management center;
however, developments might allow for point detection with roadway equipment.
For example, a CCTV might include the capability to detect an incident
based upon image changes. Additionally, this market package allows general
advisory and traffic control information to be provided to the driver
while en route.
