Based on the basic symmetric two lane cellularautomaton model(STCA),we propose a modifiedSTCA(MSTCA)for mixed traffic flow.In MSTCA,theheadway also could be used for lane changing,andthen the length for safety criterion would be extended alot.Lane changing region and first cell for lanechanging on the other lane could be located.Thesituation while there are successive vehicles satisfiesboth the safety criterion and the motivation for lanechanging;vehicles ahead would own lane changingpriority.Both the two factors will influence thefrequency of lane changing;eventually affect the totaltraffic flow.Simulation results show that the MSTCAcould acquire higher value of flux and reproduce morerealistic features of the mixed traffic flow.
