By modelling individuals as autonomous agents within a dynamic environment, ABM enables the exploration of system behaviours and the evaluation of interventions at various spatiotemporal resolutions. However, the computational intensity of ABM, particularly in large-scale simulations, remains a significant hurdle. This paper presents a novel approach to addressing these challenges through the development of a GPU-accelerated transport model, specifically applied to a road network. Utilising the FLAME-GPU framework, the proposed model demonstrates enhanced scalability and efficiency compared with traditional CPU-based simulations, such as Simulation of Urban MObility (SUMO). Through rigorous comparative analysis, this study highlights significant improvements in simulation speed and the capacity to manage larger vehicle populations. The research underscores the transformative potential of GPU acceleration in mitigating computational constraints within ABM, offering a practical framework for simulating transport systems with greater precision and depth. Extensive experimentation validates the model\u2019s ability to realistically simulate the vehicle population of the Isle of Wight, achieving a balance between computational efficiency and the accurate representation of complex traffic dynamics.<\/jats:p>","DOI":"10.3390\/systems13050376","type":"journal-article","created":{"date-parts":[[2025,5,14]],"date-time":"2025-05-14T03:59:29Z","timestamp":1747195169000},"page":"376","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["FLAME-GPU for Traffic Systems: A Scalable Agent-Based Simulation Framework"],"prefix":"10.3390","volume":"13","author":[{"given":"Maxim","family":"Smilovitskiy","sequence":"first","affiliation":[{"name":"Fujitsu Research of Europe, The Urban Building, 3-9 Albert Street, Slough SL1 2BE, UK"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8802-4028","authenticated-orcid":false,"given":"Sedar","family":"Olmez","sequence":"additional","affiliation":[{"name":"Fujitsu Research of Europe, The Urban Building, 3-9 Albert Street, Slough SL1 2BE, UK"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4657-5518","authenticated-orcid":false,"given":"Paul","family":"Richmond","sequence":"additional","affiliation":[{"name":"Department of Computer Science (DCS), University of Sheffield, Regent Court, 211 Portobello, Sheffield S1 4DP, UK"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3379-9042","authenticated-orcid":false,"given":"Robert","family":"Chisholm","sequence":"additional","affiliation":[{"name":"Department of Computer Science (DCS), University of Sheffield, Regent Court, 211 Portobello, Sheffield S1 4DP, UK"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9277-8394","authenticated-orcid":false,"given":"Peter","family":"Heywood","sequence":"additional","affiliation":[{"name":"Department of Computer Science (DCS), University of Sheffield, Regent Court, 211 Portobello, Sheffield S1 4DP, UK"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7957-7416","authenticated-orcid":false,"given":"Alvaro","family":"Cabrejas","sequence":"additional","affiliation":[{"name":"Fujitsu Research of Europe, The Urban Building, 3-9 Albert Street, Slough SL1 2BE, UK"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1988-7946","authenticated-orcid":false,"given":"Sven","family":"van den Berghe","sequence":"additional","affiliation":[{"name":"Fujitsu Research of Europe, The Urban Building, 3-9 Albert Street, Slough SL1 2BE, UK"}]},{"given":"Sachio","family":"Kobayashi","sequence":"additional","affiliation":[{"name":"Fujitsu Research of Europe, The Urban Building, 3-9 Albert Street, Slough SL1 2BE, UK"}]}],"member":"1968","published-online":{"date-parts":[[2025,5,14]]},"reference":[{"key":"ref_1","unstructured":"Mathieu, P., and De la Prieta, F.
