The Dynamic Traffic Noise Assessment (DTNA) methodology is applied to real traffic situations, then compared to on-field noise levels from measurement campaigns. This makes it possible to determine the influence of certain local traffic factors on the evaluation of noise. The pattern of distribution of vehicles along the avenue is related to the logic of traffic light control. The analysis of the inter-cycles noise variability during the simulation and measurement time shows no influence from local factors on the prediction of the dynamic traffic noise assessment tool based on CNOSSOS. A multifractal approach of acoustic waves propagation and the source behaviors in the traffic area are implemented. The novelty of the approach also comes from the multifractal model\u2019s freedom which allows the simulation, through the fractality degree, of various behaviors of the acoustic waves. The mathematical backbone of the model is developed on Cayley\u2013Klein-type absolute geometries, implying harmonic mappings between the usual space and the Lobacevsky plane in a Poincar\u00e9 metric. The isomorphism of two groups of SL(2R) type showcases joint invariant functions that allow associations of pulsations\u2013velocities manifolds type.<\/jats:p>","DOI":"10.3390\/sym12111857","type":"journal-article","created":{"date-parts":[[2020,11,11]],"date-time":"2020-11-11T20:20:33Z","timestamp":1605126033000},"page":"1857","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Dynamic Evaluation of Traffic Noise through Standard and Multifractal Models"],"prefix":"10.3390","volume":"12","author":[{"given":"Alina","family":"Petrovici","sequence":"first","affiliation":[{"name":"Faculty of Engineering, \u201cVasile Alecsandri\u201d University of Bacau, Calea Marasesti 157, 600115 Bacau, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jose Luis","family":"Cueto","sequence":"additional","affiliation":[{"name":"Laboratory of Acoustic Engineering, CASEM Building, Campus Rio San Pedro, University of Cadiz, 11510 Puerto Real, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Valentin","family":"Nedeff","sequence":"additional","affiliation":[{"name":"Faculty of Engineering, \u201cVasile Alecsandri\u201d University of Bacau, Calea Marasesti 157, 600115 Bacau, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7817-6442","authenticated-orcid":false,"given":"Enrique","family":"Nava","sequence":"additional","affiliation":[{"name":"Communication Engineering Department of the University of Malaga, Campus de Teatinos, Blv.
