Using Laser-Induced Breakdown Spectroscopy System for Detection on of Visually Unrecognizable Braking Tracks

Popis výsledku v původním jazyce

The characterization of braking tracks has proven to be essential for the determination of causes of a road traffic accident. However, with modern “Anti-lock braking system” the tracks are diffi cult to be observed visually. All newly manufactured cars are fitted with Anti-lock Braking System (ABS) and it can be assumed that the problem with visual identification of braking tracks can grow. Laser-Induced Breakdown Spectroscopy (LIBS) was selected as method advisable for fast in-situ element detection. Those braking tracks are detected based on the difference in the chemical composition of the tire tread as compared with the road surface. The detection is based on Zn as the identification element, contained in tire tread. The aim of this paper is to investigate the correlation between the car deceleration and tire tread particle content along the braking track. Special emphasis was put on the influence of road surface topology on braking track detection probability. Samples of braking tracks are obtai
