Jamming transitions in a mixed traffic cellular automata model

Abstract

In this work, we focus on the loading of passengers of buses. We use a modified Nagel-Schreckenberg (NaSch) cellular automata model that incorporates buses and passenger pickups and study the dynamics of buses in such a system. In the Nagel-Schreckenberg model, vehicles follow rules for acceleration, deceleration, random slowdown, and movement. Our modifications for buses involve stopping at a cell occupied by passengers for loading. In this model, we allow passengers to spawn along any part of the road. We analyze the interplay between the passenger arrival probability and density of buses in the system and show transitions from platooning to homogenous states with decreasing passenger arrival probability and increasing bus density.
Crossover from platooning to homogeneous phases can be induced by decreasing the passenger arrival rates, and increasing the density of buses.
