文摘In this paper,we develop a cellular automaton model to describe the phase transition of traffic flow on urbanexpressway systems with on-off-ramps and accessory roads.The lane changing rules are given in detailed,the numericalresults show that the main road and the accessory road both produce phase transitions.These phase transitions willoften be influenced by the number of lanes,lane changing,the ramp Bow,the input Bow rate,and the geometry structure.
