Abstract
Among the most important operational properties of articulated buses, ensuring their safety, it is necessary to note the course stability of traffic (CST), as often the loss of CST of a vehicle is accompanied by an accident. The parameters of the CST of a road train are closely related to the design of the running gear, in particular to the skew of the bus and trailer axles. The critical speed of rectilinear traffic was determined for different states of the articulated buses running system, which, in the absence of a bridge skew, was 32.1 m/s (116.6 km/h). The movement of the SSA is asymptotically stable. Under the action of perturbation, the stabilization time for lateral velocity is about 1 s and it increases to 2 s for the folding angle, but the amplitude of the backscatter of this angle is 10 times less than the initial perturbation, which indicates a stable asymptotic law of its change at small amplitude.
