In this study, we investigate the flux of self-driven particles (SDPs) in spontaneous zipper configuration merging at the junction of an open two-lane lattice. Particles are simulated by a cellular automaton model with a slow-to-start (SlS) rule. Spontaneous merging is induced by a local rule that the hopping probability of particles moving in one lane decreases with the approach of particles from the other lane. By means of numerical simulations, we show that, by varying the rate of injection of particles, the SlS rules and the hopping probabilities, the particle flux is improved as a result of the spontaneous zipper merging even if each SDP decreases its hopping probability during the zipper merging. We also investigate asymmetric interactions between particles moving in one lane while ignoring particles in the other lane. We find that asymmetric interactions are unsuitable for improving the particle flux except for the onset of congestion. Lastly, we estimate an approximate particle flux by a mean-field analysis, which confirms the improvement in particle flux, and is in good agreement with the results of numerical simulations.
