effective deceleration as a function of distance
value of deceleration γe obtained by dividing the difference of the squares of the initial and final speeds by twice the distance travelled while the reduction of speed is taking place

where
l is the distance between the position of the train or vehicle at the moment of the operation of the brake control and its position when the final speed is attained;
Vi is the initial speed measured at the moment of operation of the control device for the brake;
Vt is the final speed obtained at the end of the braking

quotient γe de la différence des carrés de la vitesse initiale et de la vitesse finale par le double de la distance de ralentissement parcourue

l est la distance qui sépare la position du train ou du véhicule, au moment de l'action sur la commande de frein, de sa position lorsque la vitesse finale est atteinte;
Vi est la vitesse initiale mesurée à l'instant où l'organe de commande de freinage a été actionné;
Vt est la vitesse finale atteinte à l'issue du freinage
