Smart Traffic Orchestration with Vision-Language Fusion Models

AbstractTraffic congestion is a significant problem in urban environment, which has increased economic loss, environmental pollution and travel time. The traditional traffic management system depends on the pre-programmed signal timing or isolated computer vision model to detect the vehicle. This paper proposes a vision-language fusion model (VLFM) for smart traffic orchestration, which integrates real-time visual traffic data with a dynamic, reference-individual traffic signal control. The proposed system takes advantage of multimodal deep learning to explain complex traffic patterns, predict crowds and to customize signal timing using reinforcement learning. Experimental results display adaptive reactions to low waiting time, increased throughput, and traffic events, performing better than traditional traffic management approaches. Identifying traffic accidents is an essential part of any autonomous driving or road monitoring system. An accident can appear in different types of forms, and it can be useful to prevent which type of accident is happening. The work of being able to classify traffic views as a specific type of accident is the focus of this work. We face the problem by comparing a traffic scene to a graph by comparing traffic views, where objects such as cars can be represented as nodes, and the relative distances and directions between them in the form of edges. This representation of an accident can be referred to as a visual graph, and an accident is used as an input for classifier. Better results can be achieved with a classifier that fuses visual graph input with representation from vision and language. This work introduces a multi-step, multimodal pipeline to the pre-processing video of traffic accidents, encodes them as visual graphs, and aligns this representation with vision and language modalities for accident classification. When trained on 4 sections, our method gets a balanced accuracy score of 57.77% on a (unbalanced) most of the popular identity of traffic discrepancy (DOTA) benchmark, represents an increase of 5 percent marks from the case where visual graph information is not taken into consideration Keywords: Smart Traffic, Vision-Language Models, Multimodal AI, Traffic Orchestration, Neuro-symbolism, Foundation Models, Autonomous Driving.
