Based on the changing principle of dissipative structure systematic entropy, according to the reasons of vehicle flow jam, Hi from three aspects, including reducing the increase of self-organizing entropy Δ , reducing the He positive input of exchanging entropy Δ and increasing the negative input of exchanging entropy He
