Priority evaluation to multiple scenarios focus on V2X early warning of driving assist function

Abstract

The evaluation indicator model of the scenario trigger mechanism is constructed and proposed in this paper. By analyzing the elements of the V2X early warning function scenario, five indicators, which includes time to collision, the headway, the safe distance, the lane crossing time, and post conflict vehicle entry time are employed for the comprehensive assessment. The result demonstrate the priority relationship among the total 27 scenarios. It could support to detect and identify corner traffic scenarios, to broadcast safety warnings, to improve the performance of driving assist functions.
