evacuation coordination_ud
(Future)
high water warning_ud
(Future)
High water warning information sent from one center to another.
incident information
(Future)
Notification of existence of incident and expected severity, location, time and nature of incident.
incident information request
(Future)
Request for incident information, clearing time, severity. The request can be a subscription that initiates as-needed information updates as well as a one-time request for information.
incident report
(Future)
Report of an identified incident including incident location, type, severity and other information necessary to initiate an appropriate incident response.
incident response coordination
(Future)
Incident response procedures, resource coordination, and current incident response status that are shared between allied response agencies to support a coordinated response to incidents. This flow also coordinates a positive hand off of responsibility for all or part of an incident response between agencies.
incident response status
(Future)
Status of the current incident response including traffic management strategies implemented at the site (e.g., closures, diversions, traffic signal control overrides).
remote surveillance control
(Future)
The control commands used to remotely operate another center's sensors or surveillance equipment so that roadside surveillance assets can be shared by more than one agency.
resource deployment status
(Future)
Status of traffic management center resource deployment identifying the resources available and their current deployment status.
resource request
(Future)
A request for traffic management resources to implement special traffic control measures, assist in clean up, verify an incident, etc.
road network conditions
(Existing)
Current and forecasted traffic information, road and weather conditions, incident information, and other road network status. Either raw data, processed data, or some combination of both may be provided by this architecture flow.
traffic control coordination
(Existing)
Information transfers that enable remote monitoring and control of traffic management devices. This flow is intended to allow cooperative access to, and control of, field equipment during incidents and special events and during day-to-day operations. This flow also allows 24-hour centers to monitor and control assets of other centers during off-hours, allows system redundancies and fail-over capabilities to be established, and otherwise enables integrated traffic control strategies in a region.
traffic information coordination
(Existing)
Traffic information exchanged between TMC’s. Normally would include incidents, congestion data, traffic data, signal timing plans, and real-time signal control information.
