Based on the STCA model, an improved two-lane traffic CA model in view of turn signals is proposed. The model considers changes in driver behavior before and after the signaling of the leading vehicle, and introduces rules of changing lanes, cutting lanes and yielding the right of way for the flowing vehicle. Through computer numerical simulations, this study has presented time-space diagrams and also analyzed the effects of driver behavior of the rear vehicles on traffic flow. The results reveal that a higher rate of cutting lanes incurs a heavier traffic flow in normal situations while yielding the right of way relieves traffic congestion in a bottleneck situation. Compared with the traditional model, STCA model can depict more complex traffic situations resulted from different driver behaviors and reproduce a more realistic process of traffic flow.
