INCIDENT VERIFICATION

This module is composed of 2 basic sub-modules which together fulfil the critical verification role. The incident verification and prediction core contains two applications which work in tandem: the Incident Verification Call Centre (IVCC) which filters outs duplicate calls and acts as an interface for the call desk operators and the incident verification core application. The WAP interface provides the functionality for the acceptance of incident reports via WAP-enabled handsets. The prediction and verification role is achieved through the implementation of four algorithms designed to recognise pertinent factors relating to the detection or estimation and then verify it accordingly.

Background

Incident Verification accumulates evidence and information about detected or estimated incidents, with the aim of reducing false alarms and producing verified or predicted incidents. It offers the functionality of a Call Centre, with the capabilities of registering incident phone calls either manually through an operator's interface, or automatically through a WAP interface. In addition, it offers automatic verification of incidents based on four configurable rules; trusted source, adjacent upstream detections, corroborating detections, corroborating estimations.

Incident Verification provides its complete functionality through its IV Call Center, and the IV WAP module. The particular nature of the Incident Verification System requires, on one hand, a thorough test of the system functionality residing at the control center and on the other hand a realistic design of the site tests with the proper number of participating personnel that will contribute in the WAP test.

Component Operation

The Incident Verification component is configured to "allow verification with at least one rule" and only with one of the four possible rules selected via the settings dialogue of the Incident Verification component. The four rules available are Upstream Detection, Corroborating Detection, Trusted Source and Corroborating Estimate.

It is important to set the configuration options according to the specifications selecting either the "Auto verification Rules" tab, the "General Settings" group, or the "Auto Verification Rule Settings" tab. This will indicate whether the rules selected for the test allow incidents to be verified from Incident Calls or whether the data must be entered directly into the TRAFFIC_INCIDENT table.

Note that both the Call Centre and the WAP components communicate indirectly to the module through the real time (RTDB) data base, reporting a potential traffic incident into the TRAFFIC_INCIDENT table of the RTDB.
