Research of car braking in winter conditions

Abstract

This paper presents research of some car braking characteristics in winter conditions, such as dependence of car deceleration on the road surface state, type of tires (studded or not), peculiarities of the car braking system (with antilock brake system (ABS) or without it). There were carried out braking experiments with cars at the mentioned road conditions – wet asphalt-concrete road surface and wet snow on it (initial speed, deceleration of cars were measured by the XL METER Pro Beta decelerometer). The experimentally obtained characteristics were analyzed by use of the SPSS software pack of mathematical statistics (the created statistical models were based on linear regression). The results of the carried out research processed by help of the software pack of mathematical statistics first of all are recommended to be applied to examinations of road accidents.
