Co prozradí statistika seznamu znalců

Abstract

Příspěvek pojednává o vývoji znalectví v České republice, zejména po novele zákona a prováděcích vyhlášek k 1. lednu 2021, z hlediska počtu znalců a znaleckých ústavů resp. kanceláří.

Obsolete or Viable? Revision of Lane-Change Manoeuvre Duration Empirical Calculation

“…For lane-change manoeuvre, simple equations analyzing the motion of the material point can be used. These methods are described, e.g., in [1,2].…”

“…Practical calculation of the manoeuvre duration (t rpac ) was done using the so-called Kovařík formula, described in [1] and given as Equation (3). In this formula, the mathematical constant of 2.51 was recalculated using data from experimental testing, accommodating other influences (such as delay in the steering mechanism, tyre elasticity, and others) in the overall manoeuvre duration calculation.…”

“…Analysis of vehicle lateral movement during lane change, overtaking, or crash avoidance presents a problem in traffic accident reconstruction. The lane-change manoeuvre is not used as often as braking for crash avoidance [1,2] (the mechanism of the manoeuvre is more complex compared to braking), and there is usually less evidence left by the vehicle used to identify the vehicle's trajectory (such as yaw or skid marks). If a vehicle crash occurs on a wet road surface, a crash investigator must consider lowered adhesion while analyzing vehicle dynamics.…”
