The deterministic cellular automaton 184 (the one-dimensional asymmetric simple-exclusion model with parallel dynamics) is extended to take into account injection or extraction of particles. The model presents the traffic flow on a highway with inflow or outflow of cars. Introducing injection or extraction of particles into the asymmetric simple-exclusion model drives the system asymptotically into a steady state exhibiting a self-organized criticality. The typical lifetime <m> of traffic jams scales as <m> ≈L^ν withν=0.65±0.04. It is shown that the cumulative distribution N_m(L) of life-times satisfies the finite-size scaling form N_m(L)≈L^<-1>f(m/L^ν).
