Proxy PSAP: Filtering out false alarms for PSAP overload problem

摘要

Widespread onboard sensors of an automobile and sensors installed on aftermarket devices rapidly increase the number of automotive accident messages to public safety answering point operators. Unexpected massive reports from automotive emergency call devices, such as false alarms, promote semi-urgent or non-urgent calls exponentially, referred to as the PSAP overload problem. In this paper, a proxy PSAP mitigates the problem severity and analyzes the PSAP M/M/c queue model. Numerical results show that the proxy PSAP decreases victims who must be transferred to the hospital within the golden time.
