Abstract: More investigated situations in the field of traffic modelling are those of traffic bottlenecks caused by slow vehicles or road defects. The new aspect of this paper is the simulation of vehicular dynamics near a partial reduction in a road from two lanes to one lane. In order to reduce the bad impact of waiting vehicles behind the defect region, a strategy regulating the vehicle movement in the vicinity of the reduced lane is taken into account. The simulation model is based on the cellular automata model of Nagel–Schreckenberg with additional rules of lane change. The partial lane reduction strongly reduces the road capacity, and the added regulation strategy leads to a more interesting shape of the fundamental diagram, which depends on different constraints on the model parameters, e.g., the length of the reduced lane, the maximal speed, and the length of the connection sites near the entry of the reduced lane.
