Computer vision-based accident detection through video surveillance has become a beneficial but daunting task. The performance is compared to other representative methods in table I. Recently, traffic accident detection is becoming one of the interesting fields due to its tremendous application potential in Intelligent . The parameters are: When two vehicles are overlapping, we find the acceleration of the vehicles from their speeds captured in the dictionary. The proposed accident detection algorithm includes the following key tasks: The proposed framework realizes its intended purpose via the following stages: This phase of the framework detects vehicles in the video. Road accidents are a significant problem for the whole world. Since in an accident, a vehicle undergoes a degree of rotation with respect to an axis, the trajectories then act as the tangential vector with respect to the axis. This framework was evaluated on diverse conditions such as broad daylight, low visibility, rain, hail, and snow using the proposed dataset. This function f(,,) takes into account the weightages of each of the individual thresholds based on their values and generates a score between 0 and 1. What is Accident Detection System? Open navigation menu. This framework was evaluated on. The first version of the You Only Look Once (YOLO) deep learning method was introduced in 2015 [21]. In this paper, we propose a Decision-Tree enabled approach powered by deep learning for extracting anomalies from traffic cameras while accurately estimating the start and end times of the anomalous event. This framework capitalizes on Mask R-CNN for accurate object detection followed by an efficient centroid based object tracking algorithm for surveillance footage to achieve a high Detection Rate and a low False Alarm Rate on general road-traffic CCTV surveillance footage. We can observe that each car is encompassed by its bounding boxes and a mask. The proposed framework provides a robust method to achieve a high Detection Rate and a low False Alarm Rate on general road-traffic CCTV surveillance footage.

Gkioxari, P. Dollr, and R. Girshick, Proc. 2. The family of YOLO-based deep learning methods demonstrates the best compromise between efficiency and performance among object detectors. The results are evaluated by calculating Detection and False Alarm Rates as metrics: The proposed framework achieved a Detection Rate of 93.10% and a False Alarm Rate of 6.89%. After the object detection phase, we filter out all the detected objects and only retain correctly detected vehicles on the basis of their class IDs and scores. This algorithm relies on taking the Euclidean distance between centroids of detected vehicles over consecutive frames. Before the collision of two vehicular objects, there is a high probability that the bounding boxes of the two objects obtained from Section III-A will overlap. One of the solutions, proposed by Singh et al. the development of general-purpose vehicular accident detection algorithms in have demonstrated an approach that has been divided into two parts. Currently, I am experimenting with cutting-edge technology to unleash cleaner energy sources to power the world.<br>I have a total of 8 . Typically, anomaly detection methods learn the normal behavior via training. of IEE Colloquium on Electronics in Managing the Demand for Road Capacity, Proc. detection based on the state-of-the-art YOLOv4 method, object tracking based on Consider a, b to be the bounding boxes of two vehicles A and B. However, there can be several cases in which the bounding boxes do overlap but the scenario does not necessarily lead to an accident. This method ensures that our approach is suitable for real-time accident conditions which may include daylight variations, weather changes and so on. In this paper a new framework is presented for automatic detection of accidents and near-accidents at traffic intersections. suggested an approach which uses the Gaussian Mixture Model (GMM) to detect vehicles and then the detected vehicles are tracked using the mean shift algorithm. All programs were written in Python3.5 and utilized Keras2.2.4 and Tensorflow1.12.0. As a result, numerous approaches have been proposed and developed to solve this problem. https://github.com/krishrustagi/Accident-Detection-System.git, To install all the packages required to run this python program This explains the concept behind the working of Step 3. The efficacy of the proposed approach is due to consideration of the diverse factors that could result in a collision. Computer vision applications in intelligent transportation systems (ITS) and autonomous driving (AD) have gravitated towards deep neural network architectures in recent years. detect anomalies such as traffic accidents in real time. As illustrated in fig. In this paper, a neoteric framework for detection of road accidents is proposed. traffic monitoring systems. Even though this algorithm fairs quite well for handling occlusions during accidents, this approach suffers a major drawback due to its reliance on limited parameters in cases where there are erratic changes in traffic pattern and severe weather conditions [6]. At any given instance, the bounding boxes of A and B overlap, if the condition shown in Eq. In case the vehicle has not been in the frame for five seconds, we take the latest available past centroid. Nowadays many urban intersections are equipped with Results, Statistics and Comparison with Existing models, F. Baselice, G. Ferraioli, G. Matuozzo, V. Pascazio, and G. Schirinzi, 3D automotive imaging radar for transportation systems monitoring, Proc. The robust tracking method accounts for challenging situations, such as occlusion, overlapping objects, and shape changes in tracking the objects of interest and recording their trajectories. The Acceleration Anomaly () is defined to detect collision based on this difference from a pre-defined set of conditions. to use Codespaces. Surveillance, Detection of road traffic crashes based on collision estimation, Blind-Spot Collision Detection System for Commercial Vehicles Using This paper presents a new efficient framework for accident detection at intersections . We then determine the Gross Speed (Sg) from centroid difference taken over the Interval of five frames using Eq. This paper presents a new efficient framework for accident detection They are also predicted to be the fifth leading cause of human casualties by 2030 [13]. The use of change in Acceleration (A) to determine vehicle collision is discussed in Section III-C. In this . Register new objects in the field of view by assigning a new unique ID and storing its centroid coordinates in a dictionary. The proposed framework achieved a detection rate of 71 % calculated using Eq. This section describes the process of accident detection when the vehicle overlapping criteria (C1, discussed in Section III-B) has been met as shown in Figure 2. This function f(,,) takes into account the weightages of each of the individual thresholds based on their values and generates a score between 0 and 1. Nowadays many urban intersections are equipped with surveillance cameras connected to traffic management systems. Our framework is able to report the occurrence of trajectory conflicts along with the types of the road-users involved immediately. The object detection and object tracking modules are implemented asynchronously to speed up the calculations. Leaving abandoned objects on the road for long periods is dangerous, so . This paper presents a new efficient framework for accident detection at intersections for traffic surveillance applications. The second part applies feature extraction to determine the tracked vehicles acceleration, position, area, and direction. Once the vehicles have been detected in a given frame, the next imperative task of the framework is to keep track of each of the detected objects in subsequent time frames of the footage. This is a cardinal step in the framework and it also acts as a basis for the other criteria as mentioned earlier. Computer vision-based accident detection through video surveillance has become a beneficial but daunting task. The main idea of this method is to divide the input image into an SS grid where each grid cell is either considered as background or used for the detecting an object. of IEEE Workshop on Environmental, Energy, and Structural Monitoring Systems, R. J. Blissett, C. Stennett, and R. M. Day, Digital cctv processing in traffic management, Proc. The moving direction and speed of road-user pairs that are close to each other are examined based on their trajectories in order to detect anomalies that can cause them to crash. Hence, this paper proposes a pragmatic solution for addressing aforementioned problem by suggesting a solution to detect Vehicular Collisions almost spontaneously which is vital for the local paramedics and traffic departments to alleviate the situation in time. We then determine the Gross Speed (Sg) from centroid difference taken over the Interval of five frames using Eq. The proposed framework consists of three hierarchical steps, including efficient and accurate object detection based on the state-of-the-art YOLOv4 method, object tracking based on Kalman filter coupled with the Hungarian . The object detection framework used here is Mask R-CNN (Region-based Convolutional Neural Networks) as seen in Figure 1. Current traffic management technologies heavily rely on human perception of the footage that was captured. The proposed framework provides a robust The Acceleration Anomaly () is defined to detect collision based on this difference from a pre-defined set of conditions. Additionally, it keeps track of the location of the involved road-users after the conflict has happened. Hence, this paper proposes a pragmatic solution for addressing aforementioned problem by suggesting a solution to detect Vehicular Collisions almost spontaneously which is vital for the local paramedics and traffic departments to alleviate the situation in time. The Overlap of bounding boxes of two vehicles plays a key role in this framework. If (L H), is determined from a pre-defined set of conditions on the value of . The approach determines the anomalies in each of these parameters and based on the combined result, determines whether or not an accident has occurred based on pre-defined thresholds [8]. The result of this phase is an output dictionary containing all the class IDs, detection scores, bounding boxes, and the generated masks for a given video frame.
