On the issue of assessing the errors in the operation of an interactive system for improving road safety outside settlements

Abstract

The article presents the result of the analysis of statistical data of accidents in the Krasnoyarsk Territory on sections of roads outside settlements with their greatest concentration. The main types of vehicle collisions and their accompanying conditions were identified. A mathematical apparatus for determining the minimum safe distance between vehicles located closely in an emergency zone on a section of a road outside settlements is proposed, in which it is necessary to notify the drivers of these vehicles about the danger in conditions of insufficient and/or limited visibility in various road situations, taking into account errors in positioning and determining the speed of the vehicle, the response time of the system, the effective coefficient of adhesion of the tires to the road surface. The results of experimental studies of vehicle positioning and speed errors determined by the driver’s early warning system about hazards on the road and their impact on the operability of the designed system are presented. Keywords: road safety, interactive driver warning system, positioning error, safe distance, rest of track, braking distance
