This work comprehensively studied the efficacy of modern deep learning (DL) methods in forecasting traffic accidents and enhancing Level-4 and Level-5 (L-4 and L-5) driving assistants with actionable visual and language cues. Using a rich dataset detailing accident occurrences, we juxtaposed the Transformer model against traditional time series models like ARIMA and the more recent Prophet model. Additionally, through detailed analysis, we delved deep into feature importance using principal component analysis (PCA) loadings, uncovering key factors contributing to accidents. We introduce the idea of using real-time interventions with large language models (LLMs) in autonomous driving with the use of lightweight compact LLMs like LLaMA-2 and Zephyr-7b-α. Our exploration extends to the realm of multimodality, through the use of Large Language-and-Vision Assistant (LLaVA)—a bridge between visual and linguistic cues by means of a Visual Language Model (VLM)—in conjunction with deep probabilistic reasoning, enhancing the real-time responsiveness of autonomous driving systems. In this study, we elucidate the advantages of employing large multimodal models within DL and deep probabilistic programming for enhancing the performance and usability of time series forecasting and feature weight importance, particularly in a self-driving scenario. This work paves the way for safer, smarter cities, underpinned by data-driven decision making. 000145342 536__ $$9info:eu-repo/grantAgreement/ES/MCIN/AEI/PID2021-122580NB-I00 000145342 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000145342 590__ $$a3.4$$b2023 000145342 591__ $$aCHEMISTRY, ANALYTICAL$$b34 / 106 = 0.321$$c2023$$dQ2$$eT1 000145342 591__ $$aINSTRUMENTS & INSTRUMENTATION$$b24 / 76 = 0.316$$c2023$$dQ2$$eT1 000145342 591__ $$aENGINEERING, ELECTRICAL & ELECTRONIC$$b122 / 353 = 0.346$$c2023$$dQ2$$eT2 000145342 592__ $$a0.786$$b2023 000145342 593__ $$aInstrumentation$$c2023$$dQ1 000145342 593__ $$aAnalytical Chemistry$$c2023$$dQ1 000145342 593__ $$aAtomic and Molecular Physics, and Optics$$c2023$$dQ1 000145342 593__ $$aInformation Systems$$c2023$$dQ2 000145342 593__ $$aMedicine (miscellaneous)$$c2023$$dQ2 000145342 593__ $$aBiochemistry$$c2023$$dQ2 000145342 593__ $$aElectrical and Electronic Engineering$$c2023$$dQ2 000145342 594__ $$a7.3$$b2023 000145342 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000145342 700__ $$ade Curtò, J. 000145342 700__ $$aRoig, Gemma 000145342 700__ $$aCalafate, Carlos T. 000145342 773__ $$g23, 22 (2023), 9225 [27 pp.]$$pSensors$$tSensors$$x1424-8220 000145342 8564_ $$s4386951$$uhttps://zaguan.unizar.es/record/145342/files/texto_completo.pdf$$yVersión publicada 000145342 8564_ $$s2661061$$uhttps://zaguan.unizar.es/record/145342/files/texto_completo.jpg?subformat=icon$$xicon$$yVersión publicada 000145342 909CO $$ooai:zaguan.unizar.es:145342$$particulos$$pdriver 000145342 951__ $$a2024-11-22-12:12:45 000145342 980__ $$aARTICLE
