F. System Functional Requirements. The system software provides a
simplified user friendly, color menu format at the Remote Monitoring Station.
Ensure that no special computer programming skills are required for the user to
fully access and operate this control and monitoring system.
1. Graphical Representation. Furnish system software that enables the
operator to display in color, the vehicular signals, pedestrian signals, and detector
actuations in a real time mode. Ensure that the user is able to construct an
intersection layout graphically by using predetermined intersection shapes.
2. System Capacity. Furnish a Remote Monitoring Station software that
has the capacity to monitor and control at least 24 traffic responsive masters.
Ensure that the central software is also capable of monitoring and controlling
isolated system controllers.
Furnish a system software that has the capability to manually select any
timing plan, free mode or flash mode.
Ensure that the system software has the capability of accepting,
formatting, and processing data from at least 32 system detectors from each master
controller.
3. Data Transfer. Ensure that it is possible to upload/download the
signal timing database, including coordination, and preemption settings, between
the Remote Monitoring Station and the master controller or local intersection.
Furnish a Remote Monitoring Station that provides a means to compare
a currently uploaded timing database with a previously developed database stored
in the Remote Monitoring Station memory. Ensure that it reports differences in
the databases.
During either uploading or downloading operations, ensure that the
normal traffic control operations are not suspended.
4. Security. Furnish a Remote Monitoring Station that provides for a user
specified security code before any data is altered. Maintain controller access
procedures from the Remote Monitoring Station allowing the user full security
control of all system components from a remote location.
5. Isolated Intersection Management. Furnish a Remote Monitoring
Station software that includes the capability of accessing system controllers at
remote intersection locations. Ensure that this capability includes total access to
controller timing parameters, alarm conditions, detector data, and intersection
status conditions in real time without the use of a master controller. Ensure that
this feature utilizes the local intersection controller with a dial-up modem and
telephone service.
733.08 Telephone Service. Ensure that the telephone service is a standard
dial-up service capable of supporting 2400 baud data transmission. Ensure that the
