ConfirmationOnce the RTOC is aware that there is a possible event, prior to implementing any response, the occurrence of the event must be confirmed and an initial assessment is made. The initial assessment of the event includes a precise location, description, severity, required response (i.e. police, fire, ambulance, MassHighway field personnel, etc.), and potentially an estimate of the duration of the event. It should be noted that an event detected by the RTOC operator (via CCTV) or by State Police, MassHighway personnel, or HELP Van personnel (in the field) is considered verified, and these sources provide the initial assessment information. The flow diagram shown in Exhibit 2 .2 illustrates the methods/sources available to the RTOC to verify and assess an event. Generally when the RTOC is informed of an unconfirmed event, the State Police are also aware of it and have dispatched personnel to investigate. Once the Police have arrived and assessed the situation, the RTOC may be contacted via the direct telephone line with the confirmation, event details, and any required response. Typically, however, the State Police only contact the RTOC when they require resources of MassHighway, such as field equipment or VMS messages. In some cases, either MassHighway or HELP Van personnel will be the first on the scene and will provide confirmation and event information (location, description, response, etc.). Particularly in the case of construction activities, MassHighway field personnel can provide confirmation of when the construction work commences and specific details regarding the work. If there is a MassHighway CCTV camera in the vicinity of a detected event, the RTOC operator can use the CCTV to view the event and assess its severity and the required response.
