Driver behaviour algorithms for overcoming unsignslized intersections with priority pass and for bypassing an obstacle

The paper presents the set of algorithms "cooperative driver" for the two-dimensional microscopic model of vehicular traffic based on the cellular automata theory. Cases of changing lanes when bypassing an obstacle on a multi-lane road and entering from a secondary road to the main road are considered; for each case, a flowchart of the "cooperative driver" algorithm is presented. The features of the software implementation of algorithms as part of the program package for traffic flow modeling are discussed. Test calculations have been carried out to validate the algorithms. Calculations show that the presence of “polite” drivers in the model makes it possible to reduce the waiting time for changing lanes or entry for cars without priority, which corresponds to the real situation. The presented results confirm that the created algorithms and software modules make it possible to adequately simulate various situations that arise during the vehicle movement and are caused by the "human factor".
