A new cellular automata model of traffic flow with negative exponential weighted look-ahead potential*

摘要: With the development of traffic systems, some issues such as jams become more and serious. Efficient flow theory is needed to guide overall controlling, organizing management systems. On basis cellular automata model with look-ahead potential, a new negative exponential weighted potential presented in this paper. By introducing weighting coefficient into endowing vehicles closer driver greater coefficient, modeling process suitable for driver's random decision-making which based on environment that facing. The fundamental diagrams different parameters are obtained by using numerical simulations show has an obvious effect high density flux. complex non-linear behavior also reproduced simulations.
