Compared to traditional game performed on static network, co-evolutionary game models can capture the dynamic interactive connection between players. Aiming to depict more realistic network dynamics, we propose a co-evolutionary game model that incorporates three features describing the entire connection updating process: (1) Selection range adjustment, expanding or reducing players’ neighbor selection ranges based on their payoffs; (2) Preferential selection, favoring connection with the most successful players while severing connection with low-payoff player with a certain probabilities; (3) Mutual connection willingness, requiring the consent of both players for new connections. Note that these features jointly facilitate the appearance of large connection range, which frequently emerges in real-world systems. Experimental results show that the proposed mechanism can drastically enhance cooperation level of snowdrift game with wide ranges of all parameters. More interestingly, the co-evolution process reveals how a scale-free network evolves from the initial lattice structure, providing new insights into realistic co-evolution dynamics. It is also shown that large connection ranges are essential for both high-level cooperation and scale-free network emergence.</div></div>","PeriodicalId":20152,"journal":{"name":"Physica A: Statistical Mechanics and its Applications","volume":"675 ","pages":"Article 130799"},"PeriodicalIF":2.8,"publicationDate":"2025-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144596741","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study employs a cellular automaton (CA) simulation to examine how changes in driver behavior, induced by different road signage strategies, influence traffic congestion patterns around work zones on multi-lane one-way roads. Three road sign strategies were analyzed: basic warning sign, detailed merging and speed regulation sign, and combined signs. Simulation results show that effective signage improves traffic conditions by promoting smoother lane changes and speed adjustments. The study further reveals that placing work zones in the middle lane (Lane 2) of a three-lane road tends to increase congestion unless appropriate signage is used. Moreover, analyses based on heatmaps, lane occupancy, and congestion metrics reveal the nonlinear and chaotic nature of traffic flow, showing that variations in driver behavior induced by different signage strategies lead to distinct congestion patterns. Unclear signage often leads to aggressive deceleration and merging, causing turbulent congestion waves and chaotic spillover effects. In contrast, advanced signage promotes orderly driving behavior, stabilizing traffic flow by balancing lane utilization and reducing nonlinear instabilities. These findings show the significant influence of signage-induced driver behavior on congestion patterns and provide practical insights for improving traffic management near work zones.</div></div>","PeriodicalId":20152,"journal":{"name":"Physica A: Statistical Mechanics and its Applications","volume":"675 ","pages":"Article 130816"},"PeriodicalIF":2.8,"publicationDate":"2025-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144596812","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Given the diversity of two-wheelers, including motorcycles, bicycles, e-bikes and over-standard e-bikes, a hybrid model that integrates Cellular Automata (CA) rules with Social Force (SF) principles is proposed, termed the Cellular Automata-Social Force model (CA-SF). This model is designed to simulate the interactions between cars and two-wheelers under mixed traffic conditions. By incorporating social force calculations to govern lateral movement rules, the model can simulate overtaking and lane transgression behaviors. Model parameters are derived from existing literature and real-world data, and the accuracy and reliability of the model have been validated. Through multiple sets of traffic flow simulation experiments, the study evaluates the impacts of various measures on traffic efficiency and safety in a mixed traffic environment. It is found that the physical separation of motorized and non-motorized lanes generally reduces the traffic efficiency of non-motorized two-wheelers. The impact of physical separation on traffic safety varies depending on the composition of traffic. When the proportion of two-wheelers is high, separation benefits high-speed two-wheelers such as motorcycles and over-standard e-bikes. However, when the proportion of two-wheelers is low, the opposite result occurs. Additionally, widening non-motorized lanes improves the overall traffic efficiency of two-wheelers, though the extent of improvement is less significant than the proportional increase in lane width.</div></div>","PeriodicalId":20152,"journal":{"name":"Physica A: Statistical Mechanics and its Applications","volume":"675 ","pages":"Article 130815"},"PeriodicalIF":2.8,"publicationDate":"2025-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144579504","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results demonstrate that reinforcing the strength of the information is not always helpful to decrease pre-movement time and total evacuation time. It also indicates that when the size of the moving crowd is relatively large, occupants show a strong tendency to follow them, even the directional information is in conflict with that from other sources, for example the broadcast.

Based on this, a Multi-Factor Stochastic Traffic Flow Model (MSTF) is proposed from a microscopic perspective, incorporating conditions such as safe speed, movable distance, desired distance, and stochastic slow-down probability. Simulation results show that the model can reproduce all traffic flow patterns under various boundary conditions, including Local Synchronous Pattern (LSP), Widening Synchronous Pattern (WSP), Moving Synchronous Pattern (MSP), Dissolving General Pattern (DGP), and General Pattern (GP). Moreover, when in a critical state, the model accurately reproduces traffic flow metastable state, spatio-temporal patterns, and phase transitions. Calibration and validation results indicate that the model effectively simulates the actual phenomenon of spacing fluctuations between following vehicles (with a minimum RMSPE of less than 0.05) and accurately reproduces the concave growth pattern of speed oscillations in car-following platoons. The research outcomes further highlight, both theoretically and numerically, the influence of stochastic factors on traffic flow stability.
