| Abstract: | We present results relative to a simple cellular automata model without periodic boundary conditions for an highway with on-ramps.
Simulations performed with this model reproduce experimental phenomena observed in traffic such as free flow, synchronized
flow, congested flow, lane inversion, forward and backward propagating waves. On-ramps play the important role of nucleation
points for the dynamic features of traffic.
