BRAKING DISTANCES OF VEHICLES INFLUENCED BY RANDOM PAVEMENT UNEVENNESSES

SUMMARY

Braking ability of vehicles is one of the most important features which influence the safety and reliability of traffic. The maximum applicable deceleration enabling fast forward speed reduction depends on a great number of factors the physical manifestations of which are not yet known in sufficient details. Thus only simple empirical formulae are used as a rule. In this study, the basic variables relevant to this task are considered to be random processes with analytically simple properties. With this approach the influence of random pavement uneven-nesses on braking times and braking distances could be studied. Both analytical models and basic results of connected experimental work are given.
