Incident Management Service. The Freeway Traffic Management Center provides for incident detection to identify any incidents or emergencies that require support from appropriate resources. It also allows for adjustments in traffic control to enable faster response by incident resources and to reduce impacts due to incidents by allowing traffic to be diverted to alternate routes and by alerting the travelers to conditions that they may encounter due to on-going incidents. Highway Helper Vehicles provide a patrol capability to find and assist in clearing incidents from the roadways such as to minimize disruptions to traffic flow.
Incident Management Service. Advantages . Reduced staffing by consolidating dispatch operations • Can access common information systems • Fewer incident management systems (CAD, other equipment) • Easier to infuse new technology at central site • Forces agencies to pool resources to improve efficiency Disadvantages • Requires co-location of resources • Most difficult to implement (requires new facilities) Issues • Who owns/controls/maintains the Regional ITS Management Center • Coordination - multiple jurisdictions governing center operations Incident Management Service Architecture Trade-off Evaluation AS-IS Architecture #1 Arichitecture #2 Architecture #3 Function: Information Completeness * Each dispatch center and resources assigned to the dispatch center utilize local procedures to gather and maintain incident information ++ Incident information gathering will be standardized for consistency and completeness across dispatch centers and resources ++ Same as architecture #l ++ Same as architecture #I
Incident Management Service. The Broadcast Information Provider is utilized to provide information to travelers regarding the status of planned and unplanned incidents which may impact their travel plans. In addition, they may provide an incident detection service by notifying dispatch center(s) of incidents reported by their listeners. Additional architectural details about this component are located in separate database reports document titled:
Incident Management Service. The Centralized Control Signal Center provides incident detection and traffic control functions to route traffic around incident locations and allow faster response to incidents by emergency resources. These functions are accomplished by utilizing Centralized Roadside Equipment that is controlled by the Centralized Control Signal Center. Figure 1 and Figure 2, Centralized Control Signal Center - Component Interfaces, show the data flow relationships between the Centralized Control Signal Center Component and other associated components. Additional architectural details about this component are located in separate database reports document titled: Appendix A. Component Requirements Appendix B. Input Data Flows for Components Appendix C. Output Data Flows for Components
Incident Management Service. The Demand Responsive Transit Center requests the necessary resources needed to resolve an incident in a timely manner. During the incident, the center tracks the progression of the incident status, monitors the location of resources in order to determine estimated time of arrival of resources, determines estimated time to clear an incident, monitors the condition of the dispatched resources, and dispatches additional resource requirements as needed. In addition, the various components used by the Demand Responsive Transit Center also provides for incident detection.
Incident Management Service. The External Information Source(s) provide an incident detection service by notifying dispatch center(s) of incidents and special events. Acknowledgement messages are returned to notify the source that the message was received and an appropriate response has been requested.
Incident Management Service. The Maintenance Garage(s) will provide the necessary resources and work areas needed to repair and maintain vehicles and equipment utilized in incident management. - Maintenance Service: (The physical architecture and functional allocations were not performed for this service, and are left for future definition.) Additional architectural details about this component are located in separate database reports document titled:
Incident Management Service. The Regional ITS Management Center coordinates public and private agency emergency support across jurisdictional boundaries to provide optimum use of resources required to resolve a specific incident.
Incident Management Service. The State Patrol Dispatch Center dispatches emergency vehicles (State Patrol) to incidents, and notifies additional public and private agencies to request additional resources required to resolve a specific incident. In addition, State Patrol Dispatch Center collects incident detection data from its patrol vehicles, and provides an E-91 1 service for collection of incident information from private individuals.
Incident Management Service. Advantages Access to non-sensitive data is centralized at Regiorial ITS Management System • Minimal institutional implementation impact • Data consistancy/validation/verification checking can be performed • Public access of information will be made easier (single point of access) Disadvantages • Degraded mode capability is more complicated • Single point of failure • More interfaces to manage Issues • Who owns/operates/funds/maintains Regional ITS Management System . • Need to link information from multiple sources to a single incident Incident history record needs to be protected from general public access • Data distribution process Architecture #3
