Abstract

Accelerations and braking are needed in traffic to allow a vehicle to travel from one place to another. Also present during the drive are lateral accelerations, which are active in curves. The accelerations and braking active during the drive are usually in the range of one fifth to one third of maximum value. In critical and unexpected situations, the accelerations and braking are increased up to maximum values. Maximum values of acceleration and braking depend on roughness of ground, type of ground, quality of tires, quality of vehicle brakes, etc. Because of critical and unexpected situations, there are many accidents on the roads. In these cases, accelerations or braking reach their limit values and many times the vehicle becomes uncontrollable. In this paper the system for measurement and analyses of accelerations and braking in traffic of vehicles is presented. These systems are necessary for analyses of different accidents in traffic and to define maximal longitudinal accelerations, maximal lateral accelerations and maximal braking in different situations. Also presented in this article are practical measurements and analyses of maximal accelerations and braking for selected cars, which were measured on a straight road, and comparisons of these measurements with the producer data and accelerations and braking measured on a racetrack.
