Abstract: Inspired by the finite resources in transport systems, we propose a two-lane totally asymmetric simple exclusion process model with attachment, detachment, and a limited supply of particles. We use a generalized mean-field theory in collaboration with a finite difference scheme and boundary layer analysis to evaluate the significance of limited resources in our proposed system. The outcomes are verified using Monte Carlo simulations. The steady-state behavior of the system is determined using phase diagrams, density profiles, and phase transitions. The study reports a novel phenomenon in which a phase occupies two different regions far from each other in the phase diagrams for an intermediate value of the total number of particles in the system. We also observe unique single and multiple re-entrance transitions, double shock, and varied new mixed phases, leading to bulk-induced phase transitions as exciting findings in the present study.
