Model-based Design of a Roadside Unit for Emergency and Disaster Management

Every year, a massive number of deaths happen because of traffic accidents. In order to increase the traffic victim’s survival rates, it is important to reduce the arrival time of medical and trauma intervention teams to accidents’ sites. Automatic incident detection provides faster incident reporting to decrease the delay of arrival time of first responders. In this paper, we propose a roadside unit (RSU) that automatically detects traffic incidents using multiple detection mechanisms, verifies to reduce false alarms and reports to the intelligent traffic management system. The proposed RSU is modeled in Architecture Analysis and Design Language (AADL). Simulation results show that our RSU model is schedulable with low processor utilization factors, and provides incident detection and reporting in under three minutes.
