Abstract

This paper studies slow-to-start effect in two-dimensional Biham–Middleton–Levine (BML) traffic flow model with traffic light periods $T = 2 τ$ . In most cases, the model exhibits free flow, jam, and phase separation phenomenon. Nevertheless, when the slow-to-start parameter $p = 0$ , and traffic light parameter $τ = 3$ or 5, it is found that phase separation phenomenon does not occur. We have explained this via the evolution process from a designed regular initial configuration. Moreover, it is also found that the free flow self-organizes into grid-like structure when τ is large and the slow-to-start parameter $0 < p < 1$ .

Extending Particle Hopping Models for road traffic with Timed Automata
2020, Physica A: Statistical Mechanics and its Applications
Particle Hopping Models (PHM) are discrete models employed to mimic vehicular traffic, protein transport mechanisms, granular flows and other extended dynamic systems. Despite their simplistic exclusion principle, PHM correctly reproduce many macroscopic phenomena. Currently, positions of simulated entities in a PHM are updated at distinct moments by random selection, sequential iteration or in parallel. We advance these techniques by developing two time-continuous PHM for traffic applications on one-dimensional lattices and two-dimensional chequerboard topologies. By employing Timed Automata (TA) to formulate temporal boundaries and guide the movement process, driver behaviour can be finely adjusted. Both models are equipped with several stochastic components which influence critical densities and transition progressions. The proposed models can emulate almost all discrete update schemes at the level of individual movements and reproduce all major macroscopic free-flow to jamming progressions.
Dissipation of traffic congestion using autonomous-based car-following model with modified optimal velocity
2020, Physica A: Statistical Mechanics and its Applications

In the area of vehicular transport, traffic congestion is one of the most pertinent issues that has been widely studied. Traffic signal optimization [16], density and delay-feedback control [17–19], real-time information provision [20], and autonomous vehicles [21–23] are examples of proposed methods to solve the problem. In this work, we use the stochastic car-following model with continuous spatial–temporal evolution to investigate the system on a circular road.
We investigate dynamical properties of traffic flow using the stochastic car-following model with modified optimal velocity on circular road. The safety distance following the two-second rule and autonomous vehicles obeying simple requirements are incorporated into the model. The dynamic safety distance increases in a light traffic condition where the average driving velocity is high, while decreases in a dense traffic condition in anticipation of slower traffic motion. The results show that the presence of the autonomous vehicles can enhance overall velocity and traffic current of the system, and postpone the traffic congestion. In a particular phase region, imposing a speed limit enables the system to leave the congested flow phase. The density-dependent speed limit in autonomous-free condition is obtained to achieve the optimal traffic flow.
Analytical and simulation studies of intersecting pedestrian flow on the 2D lattice with parallel update rule
2019, Physica A: Statistical Mechanics and its Applications
Citation Excerpt :
The BML-R model has been extended to a more general case, where each pedestrian has three moving directions [49]. A phase separation phenomenon has been observed when the slow-to-start effect in the BML model is considered [50]. Almost all of the models presented above are random, random sequential, frozen shuffle or sublattice-parallel.
The intersecting pedestrian flow on the $2 D$ lattice with parallel update rule is studied. Each pedestrian has three moving directions without a back step. An intermediate phase has been found in which some pedestrians could move along the border of jamming stripes. A improved cluster mean field method has been proposed for the moving phase. A mean field analysis was also developed to analyze the intermediate phase. The analytical results agree with the simulation results well. The empty site moves along the interface of jamming stripes when the system only has one empty site. The average movement of empty site in each time step has been analyzed through the master equations.
A new mechanism for metastability of under-saturated traffic responsible for time-delayed traffic breakdown at the signal
2014, Computer Physics Communications
In this paper we introduce a new mechanism of metastability of under-saturated traffic at the signal that is responsible for a time-delayed traffic breakdown revealed by Kerner (2011). In our model, we assume that the metastability of under-saturated traffic at the signal is caused by a dependence of the mean time of driver acceleration from a queue at the signal on the driver’s stopped time within the queue. With the use of Nagel–Schreckenberg model, we demonstrate that this mechanism of the metastability of city traffic can lead to the time-delayed traffic breakdown at the signal.
Effect of slow-to-start in the extended BML model with four-directional traffic
2014, Physics Letters, Section A: General, Atomic and Solid State Physics
In this paper, an extended Biham–Middleton–Levine (BML) model is proposed to simulate complex characteristics of four-directional traffic flow by considering the effect of slow-to-start. The simulation results show that the system does not exhibit a sharp transition from moving phase to jamming phase, which is consistent with the results of the latest studies about the original BML model. Differently from the structure geometric patterns in previous studies, a new phase separation phenomenon, i.e., the coexistence of multiple free flow stripes and multi-local jams, can be observed. The formation mechanisms of typical dynamic patterns are also explored. Furthermore, a mean field analysis for the maximum velocity in the moving phase is obtained, which is in good accordance with simulation results. In addition, an interesting feature is found that this new coexistence phenomenon of two phases is determined only by the effect of slow-to-start and is completely independent of traffic light (only considering red light and green light) period.
