The traditional cellular automaton (CA) model assumes that drivers only receive information from the preceding vehicles, e.g. the brake light information. However, in reality, drivers not only perceive information from downstream but can also get upstream information, e.g. the honk stimulation....

The paper mainly studies the following vehicle’s honk effect on the driver of its predecessors in the single-lane cellular automaton model (CA model); besides, the determined condition of honk’s state is investigated in detail, which has seldom been studied before. Then, the influence of...

The essential distinction between the Fundamental Diagram Approach (FDA) and Kerner’s three-phase theory (KTPT) is the existence of a unique gap–speed (or flow–density) relationship in the former class. In order to verify this relationship, empirical data are analyzed with the following...
