4.4.2.11 Incident Response Features
The incident response features have been developed to provide a logical process that allows an operator to locate, confirm, move and record data associated with each incident. Particularly powerful is the incident response scenario process that suggests TAR and VMS messages to the operator dynamically. The rules for these incident response suggestions follow the functional requirements document. Incident response features in the prototype include:
- Incidents may be added to system by clicking on the correct location on the map.
- Incidents may be relocated by moving the map symbol, or by editing the incident properties and selecting the appropriate link.
- A user may enter lane blockage information through graphical representation of the link, see figure 4-40 for an illustration.
Figure 4-40. Entering Incident Information
CSC/PBFI Advantage: The number of lanes blocked by an incident is entered by highlighting the appropriate area on the screen.
- When a user adds an incident to the system, the closest camera within two miles is activated.
- When incident is confirmed, the user is presented with a response scenario, see figure 4-41 for an example.
Figure 4-41. Choosing Incident Responses
CSC/PBFI Advantage: The system provides the operator with suggested incident responses.
- Scenarios are updated as conditions change. VMS and TAR objects automatically suggest correct messages according to MDSHA rules.
- Scenarios can be set to auto-execute. In this case, the devices will always be automatically updated to show the currently suggested message. The system periodically checks all devices and verifies they are showing the suggested message. Those that are not are re-sent the suggested message.
- Response scenarios use symbols to inform the user if the VMS or TAR device is currently playing the suggested message. A red symbol indicates that the device is not showing the system suggested message, green symbol indicates that it is.
- Response scenarios allow users to edit each element. User edited elements are not overwritten when information changes. Red symbols indicate a message will not be overwritten by a system suggestion.
- Users may select messages and request a suggestion. This will overwrite the current suggestion and/or current user locked response messages.
- All messages that are sent to devices as part of a response scenario would be rolled back when the incident goes away.
- As shown in figure 4-42, incident report keeps track of all VMS and TAR devices utilized during incident response.
