If (L H), is determined from a pre-defined set of conditions on the value of . This parameter captures the substantial change in speed during a collision thereby enabling the detection of accidents from its variation. 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. Section II succinctly debriefs related works and literature. For certain scenarios where the backgrounds and objects are well defined, e.g., the roads and cars for highway traffic accidents detection, recent works [11, 19] are usually based on the frame-level annotated training videos (i.e., the temporal annotations of the anomalies in the training videos are available - supervised setting). The trajectories are further analyzed to monitor the motion patterns of the detected road-users in terms of location, speed, and moving direction. A classifier is trained based on samples of normal traffic and traffic accident. In the event of a collision, a circle encompasses the vehicles that collided is shown. detection. A popular . become a beneficial but daunting task. Figure 4 shows sample accident detection results by our framework given videos containing vehicle-to-vehicle (V2V) side-impact collisions.

Computer Vision-based Accident Detection in Traffic Surveillance Abstract: Computer vision-based accident detection through video surveillance has become a beneficial but daunting task. The next task in the framework, T2, is to determine the trajectories of the vehicles. , to locate and classify the road-users at each video frame. This results in a 2D vector, representative of the direction of the vehicles motion. The Scaled Speeds of the tracked vehicles are stored in a dictionary for each frame. The incorporation of multiple parameters to evaluate the possibility of an accident amplifies the reliability of our system. Then, we determine the distance covered by a vehicle over five frames from the centroid of the vehicle c1 in the first frame and c2 in the fifth frame. This framework is based on local features such as trajectory intersection, velocity calculation and their anomalies. 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. 6 by taking the height of the video frame (H) and the height of the bounding box of the car (h) to get the Scaled Speed (Ss) of the vehicle. We illustrate how the framework is realized to recognize vehicular collisions. Detection of Rainfall using General-Purpose Annually, human casualties and damage of property is skyrocketing in proportion to the number of vehicular collisions and production of vehicles [14]. The centroid tracking mechanism used in this framework is a multi-step process which fulfills the aforementioned requirements. PDF Abstract Code Edit No code implementations yet. Therefore, Since most intersections are equipped with surveillance cameras automatic detection of traffic accidents based on computer vision technologies will mean a great deal to traffic monitoring systems. This paper presents a new efficient framework for accident detection at intersections . Statistically, nearly 1.25 million people forego their lives in road accidents on an annual basis with an additional 20-50 million injured or disabled. of IEEE International Conference on Computer Vision (ICCV), W. Hu, X. Xiao, D. Xie, T. Tan, and S. Maybank, Traffic accident prediction using 3-d model-based vehicle tracking, in IEEE Transactions on Vehicular Technology, Z. Hui, X. Yaohua, M. Lu, and F. Jiansheng, Vision-based real-time traffic accident detection, Proc. The dataset is publicly available The conflicts among road-users do not always end in crashes, however, near-accident situations are also of importance to traffic management systems as they can indicate flaws associated with the signal control system and/or intersection geometry. The average processing speed is 35 frames per second (fps) which is feasible for real-time applications. The trajectory conflicts are detected and reported in real-time with only 2 instances of false alarms which is an acceptable rate considering the imperfections in the detection and tracking results. Let x, y be the coordinates of the centroid of a given vehicle and let , be the width and height of the bounding box of a vehicle respectively. This framework was found effective and paves the way to the development of general-purpose vehicular accident detection algorithms in real-time. To enable the line drawing feature, we need to select 'Region of interest' item from the 'Analyze' option (Figure-4). By taking the change in angles of the trajectories of a vehicle, we can determine this degree of rotation and hence understand the extent to which the vehicle has underwent an orientation change. Section III delineates the proposed framework of the paper. The proposed accident detection algorithm includes the following key tasks: Vehicle Detection Vehicle Tracking and Feature Extraction Accident Detection The proposed framework realizes its intended purpose via the following stages: Iii-a Vehicle Detection This phase of the framework detects vehicles in the video. This framework is based on local features such as trajectory intersection, velocity calculation and their anomalies. In computer vision, anomaly detection is a sub-field of behavior understanding from surveillance scenes. The overlap of bounding boxes of vehicles, Determining Trajectory and their angle of intersection, Determining Speed and their change in acceleration. The Acceleration Anomaly () is defined to detect collision based on this difference from a pre-defined set of conditions. Build a Vehicle Detection System using OpenCV and Python We are all set to build our vehicle detection system! computer vision techniques can be viable tools for automatic accident The probability of an accident is determined based on speed and trajectory anomalies in a vehicle after an overlap with other vehicles.

He, G. Gkioxari, P. Dollr, and R. Girshick, Proc. If the boxes intersect on both the horizontal and vertical axes, then the boundary boxes are denoted as intersecting. The two averaged points p and q are transformed to the real-world coordinates using the inverse of the homography matrix H1, which is calculated during camera calibration [28] by selecting a number of points on the frame and their corresponding locations on the Google Maps [11]. The intersection over union (IOU) of the ground truth and the predicted boxes is multiplied by the probability of each object to compute the confidence scores. This architecture is further enhanced by additional techniques referred to as bag of freebies and bag of specials. Numerous studies have applied computer vision techniques in traffic surveillance systems [26, 17, 9, 7, 6, 25, 8, 3, 10, 24] for various tasks. Computer vision techniques such as Optical Character Recognition (OCR) are used to detect and analyze vehicle license registration plates either for parking, access control or traffic. The video clips are trimmed down to approximately 20 seconds to include the frames with accidents. Activity recognition in unmanned aerial vehicle (UAV) surveillance is addressed in various computer vision applications such as image retrieval, pose estimation, object detection, object detection in videos, object detection in still images, object detection in video frames, face recognition, and video action recognition. Considering the applicability of our method in real-time edge-computing systems, we apply the efficient and accurate YOLOv4 [2] method for object detection. Each video clip includes a few seconds before and after a trajectory conflict. of International Conference on Systems, Signals and Image Processing (IWSSIP), A traffic accident recording and reporting model at intersections, in IEEE Transactions on Intelligent Transportation Systems, T.

The proposed framework is able to detect accidents correctly with 71% Detection Rate with 0.53% False Alarm Rate on the accident videos obtained under various ambient conditions such as daylight, night and snow. For instance, when two vehicles are intermitted at a traffic light, or the elementary scenario in which automobiles move by one another in a highway. Video processing was done using OpenCV4.0. Computer Vision-based Accident Detection in Traffic Surveillance Earnest Paul Ijjina, Dhananjai Chand, Savyasachi Gupta, Goutham K Computer vision-based accident detection through video surveillance has become a beneficial but daunting task. Statistically, nearly 1.25 million people forego their lives in road accidents on an annual basis with an additional 20-50 million injured or disabled. At any given instance, the bounding boxes of A and B overlap, if the condition shown in Eq. traffic video data show the feasibility of the proposed method in real-time Similarly, Hui et al. Note: This project requires a camera. 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. Nowadays many urban intersections are equipped with Automatic detection of traffic incidents not only saves a great deal of unnecessary manual labor, but the spontaneous feedback also helps the paramedics and emergency ambulances to dispatch in a timely fashion. Currently, most traffic management systems monitor the traffic surveillance camera by using manual perception of the captured footage. We then utilize the output of the neural network to identify road-side vehicular accidents by extracting feature points and creating our own set of parameters which are then used to identify vehicular accidents. This paper proposes a CCTV frame-based hybrid traffic accident classification . This section describes our proposed framework given in Figure 2. The state of each target in the Kalman filter tracking approach is presented as follows: where xi and yi represent the horizontal and vertical locations of the bounding box center, si, and ri represent the bounding box scale and aspect ratio, and xi,yi,si are the velocities in each parameter xi,yi,si of object oi at frame t, respectively. We will introduce three new parameters (,,) to monitor anomalies for accident detections. after an overlap with other vehicles.

The Hungarian algorithm [15] is used to associate the detected bounding boxes from frame to frame. 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. The most common road-users involved in conflicts at intersections are vehicles, pedestrians, and cyclists [30]. The family of YOLO-based deep learning methods demonstrates the best compromise between efficiency and performance among object detectors. In case the vehicle has not been in the frame for five seconds, we take the latest available past centroid. 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, have demonstrated an approach that has been divided into two parts. have demonstrated an approach that has been divided into two parts. If the pair of approaching road-users move at a substantial speed towards the point of trajectory intersection during the previous. The next criterion in the framework, C3, is to determine the speed of the vehicles. The centroid tracking mechanism used in this framework is a multi-step process which fulfills the aforementioned requirements. including near-accidents and accidents occurring at urban intersections are 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]. 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. In this paper, a neoteric framework for detection of road accidents is proposed. The proposed framework Current traffic management technologies heavily rely on human perception of the footage that was captured. to detect vehicular accidents used the feed of a CCTV surveillance camera by generating Spatio-Temporal Video Volumes (STVVs) and then extracting deep representations on denoising autoencoders in order to generate an anomaly score while simultaneously detecting moving objects, tracking the objects, and then finding the intersection of their tracks to finally determine the odds of an accident occurring. 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. Road accidents are a significant problem for the whole world. Traffic closed-circuit television (CCTV) devices can be used to detect and track objects on roads by designing and applying artificial intelligence and deep learning models. The condition stated above checks to see if the centers of the two bounding boxes of A and B are close enough that they will intersect. The layout of this paper is as follows. Additionally, the Kalman filter approach [13]. All the experiments conducted in relation to this framework validate the potency and efficiency of the proposition and thereby authenticates the fact that the framework can render timely, valuable information to the concerned authorities. Additionally, it performs unsatisfactorily because it relies only on trajectory intersections and anomalies in the traffic flow pattern, which indicates that it wont perform well in erratic traffic patterns and non-linear trajectories. The primary assumption of the centroid tracking algorithm used is that although the object will move between subsequent frames of the footage, the distance between the centroid of the same object between two successive frames will be less than the distance to the centroid of any other object. Many people lose their lives in road accidents. Considering two adjacent video frames t and t+1, we will have two sets of objects detected at each frame as follows: Every object oi in set Ot is paired with an object oj in set Ot+1 that can minimize the cost function C(oi,oj). The surveillance videos at 30 frames per second (FPS) are considered. Learn more. The proposed framework capitalizes on Mask R-CNN for accurate object detection followed by an efficient centroid based object tracking algorithm for surveillance footage. The object detection framework used here is Mask R-CNN (Region-based Convolutional Neural Networks) as seen in Figure 1. Before running the program, you need to run the accident-classification.ipynb file which will create the model_weights.h5 file. The next task in the framework, T2, is to determine the trajectories of the vehicles. Road traffic crashes ranked as the 9th leading cause of human loss and account for 2.2 per cent of all casualties worldwide [13]. This paper presents a new efficient framework for accident detection detection based on the state-of-the-art YOLOv4 method, object tracking based on This is a recurring payment that will happen monthly, If you exceed more than 500 images, they will be charged at a rate of $5 per 500 images. All programs were written in Python3.5 and utilized Keras2.2.4 and Tensorflow1.12.0. 2. Since we are focusing on a particular region of interest around the detected, masked vehicles, we could localize the accident events. Although there are online implementations such as YOLOX [5], the latest official version of the YOLO family is YOLOv4 [2], which improves upon the performance of the previous methods in terms of speed and mean average precision (mAP). The existing video-based accident detection approaches use limited number of surveillance cameras compared to the dataset in this work. We start with the detection of vehicles by using YOLO architecture; The second module is the . Google Scholar [30]. If you find a rendering bug, file an issue on GitHub. This is a cardinal step in the framework and it also acts as a basis for the other criteria as mentioned earlier. 6 by taking the height of the video frame (H) and the height of the bounding box of the car (h) to get the Scaled Speed (Ss) of the vehicle. The process used to determine, where the bounding boxes of two vehicles overlap goes as follow: road-traffic CCTV surveillance footage. Then, to run this python program, you need to execute the main.py python file. This paper introduces a solution which uses state-of-the-art supervised deep learning framework. of IEEE International Conference on Acoustics, Speech, and Signal Processing (ICASSP), Object detection for dummies part 3: r-cnn family, Faster r-cnn: towards real-time object detection with region proposal networks, in IEEE Transactions on Pattern Analysis and Machine Intelligence, Road traffic injuries and deathsa global problem, Deep spatio-temporal representation for detection of road accidents using stacked autoencoder, Real-Time Accident Detection in Traffic Surveillance Using Deep Learning, Intelligent Intersection: Two-Stream Convolutional Networks for for Vessel Traffic Surveillance in Inland Waterways, Traffic-Net: 3D Traffic Monitoring Using a Single Camera, https://www.aicitychallenge.org/2022-data-and-evaluation/. 7. The robustness Update coordinates of existing objects based on the shortest Euclidean distance from the current set of centroids and the previously stored centroid. The performance is compared to other representative methods in table I. 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. 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. Anomalies are typically aberrations of scene entities (people, vehicles, environment) and their interactions from normal behavior. The trajectories of each pair of close road-users are analyzed with the purpose of detecting possible anomalies that can lead to accidents. Automatic detection of traffic accidents is an important emerging topic in traffic monitoring systems. method with a pre-trained model based on deep convolutional neural networks, tracking the movements of the detected road-users using the Kalman filter approach, and monitoring their trajectories to analyze their motion behaviors and detect hazardous abnormalities that can lead to mild or severe crashes. task. This paper presents a new efficient framework for accident detection at intersections for traffic surveillance applications. This is the key principle for detecting an accident. https://github.com/krishrustagi/Accident-Detection-System.git, To install all the packages required to run this python program The use of change in Acceleration (A) to determine vehicle collision is discussed in Section III-C. Therefore, for this study we focus on the motion patterns of these three major road-users to detect the time and location of trajectory conflicts. The GitHub link contains the source code for this deep learning final year project => Covid-19 Detection in Lungs. From this point onwards, we will refer to vehicles and objects interchangeably. The inter-frame displacement of each detected object is estimated by a linear velocity model. Mask R-CNN not only provides the advantages of Instance Segmentation but also improves the core accuracy by using RoI Align algorithm. 5. This is accomplished by utilizing a simple yet highly efficient object tracking algorithm known as Centroid Tracking [10]. The total cost function is used by the Hungarian algorithm [15] to assign the detected objects at the current frame to the existing tracks. surveillance cameras connected to traffic management systems. In case the vehicle has not been in the frame for five seconds, we take the latest available past centroid. A Vision-Based Video Crash Detection Framework for Mixed Traffic Flow Environment Considering Low-Visibility Condition In this paper, a vision-based crash detection framework was proposed to quickly detect various crash types in mixed traffic flow environment, considering low-visibility conditions. The framework is built of five modules. The Trajectory Anomaly () is determined from the angle of intersection of the trajectories of vehicles () upon meeting the overlapping condition C1. This section describes our proposed framework given in Figure 2. All programs were written in Python3.5 and utilized Keras2.2.4 and Tensorflow1.12.0. The proposed framework is purposely designed with efficient algorithms in order to be applicable in real-time traffic monitoring systems. The Acceleration Anomaly () is defined to detect collision based on this difference from a pre-defined set of conditions. This could raise false alarms, that is why the framework utilizes other criteria in addition to assigning nominal weights to the individual criteria.
