A study on an improved Nagel-Schreckenberg traffic flow -model with open boundary conditions
开放边界条件下改进的Nagel-Schreckenberg交通流模型的研究

Using the improved Nagel Schreckenberg traffic model with open boundary conditions,we present the fundamental diagrams of traffic flow under different parameters by numerical simulation.It turns out that the traffic flow of the improved Nagel Schrec kenberg model is greater than that of the Nagel Schreckenberg model,then we analyse the characters and critical points of the transition from free flow phase to maximum current phase and the transition from jamming phase to free flow phase.
