ABSTRACT: This research is dedicated to the study of dynamics
of vehicles moving through the additional entry lanes of a roundabout.
Using the data created on the base of that model the constant coefficients of
the sixth-degree polynomial function, previously proposed by us, have been
found. In result of this there were obtained two analytic equations of
vehicles’ movement, where one of them presented with the positive sign of the leading
coefficient and the other one negative. These two equations allowed to make
comprehensive investigation of the delays
and the kinematics of the vehicles moving by such kinds of lanes. Based on the appropriate calculations it is
determined vehicles’ consequent delays, velocities, accelerations and
decelerations. Analyzing the delays, the dynamics of accelerations and
decelerations, it is done an assumption that if the leading coefficient of
algorithm of movement of vehicles is negative than it will lead to larger
deceleration and consequently higher environmental pollutions and higher
noises.
