In this paper, a neoteric framework for detection of road accidents is proposed. This framework was found effective and paves the way to the development of general-purpose vehicular accident detection algorithms in real-time. This framework was evaluated on. This algorithm relies on taking the Euclidean distance between centroids of detected vehicles over consecutive frames. 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.

Abrantes, and J. S. Marques, An algorithm for centroid-based tracking of moving objects, Proc. accident is determined based on speed and trajectory anomalies in a vehicle We determine this parameter by determining the angle () of a vehicle with respect to its own trajectories over a course of an interval of five frames. 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 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. 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 II succinctly debriefs related works and literature. To contribute to this project, knowledge of basic python scripting, Machine Learning, and Deep Learning will help. The first version of the You Only Look Once (YOLO) deep learning method was introduced in 2015 [21]. 2. The dataset is publicly available 5. However, it suffers a major drawback in accurate predictions when determining accidents in low-visibility conditions, significant occlusions in car accidents, and large variations in traffic patterns, 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. 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. We estimate. Additionally, despite all the efforts in preventing hazardous driving behaviors, running the red light is still common. 2. , the architecture of this version of YOLO is constructed with a CSPDarknet53 model as backbone network for feature extraction followed by a neck and a head part. 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. 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. We can observe that each car is encompassed by its bounding boxes and a mask. This paper presents a new efficient framework for accident detection at intersections . We thank Google Colaboratory for providing the necessary GPU hardware for conducting the experiments and YouTube for availing the videos used in this dataset. A dataset of various traffic videos containing accident or near-accident scenarios is collected to test the performance of the proposed framework against real videos. In this paper, a neoteric framework for detection of road accidents is proposed. 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. This takes a substantial amount of effort from the point of view of the human operators and does not support any real-time feedback to spontaneous events. 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. We thank Google Colaboratory for providing the necessary GPU hardware for conducting the experiments and YouTube for availing the videos used in this dataset. The GitHub link contains the source code for this deep learning final year project => Covid-19 Detection in Lungs. After that administrator will need to select two points to draw a line that specifies traffic signal. A new cost function is This results in a 2D vector, representative of the direction of the vehicles motion. The model of computer-assisted analysis of lung ultrasound image is built which has shown great potential in pulmonary condition diagnosis and is also used as an alternative for diagnosis of COVID-19 in a patient. Mask R-CNN improves upon Faster R-CNN [12] by using a new methodology named as RoI Align instead of using the existing RoI Pooling which provides 10% to 50% more accurate results for masks[4]. 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. We then determine the Gross Speed (Sg) from centroid difference taken over the Interval of five frames using Eq. In the UAV-based surveillance technology, video segments captured from . objects, and shape changes in the object tracking step. The most common road-users involved in conflicts at intersections are vehicles, pedestrians, and cyclists [30]. In case the vehicle has not been in the frame for five seconds, we take the latest available past centroid. A classifier is trained based on samples of normal traffic and traffic accident. 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. traffic monitoring systems. If the dissimilarity between a matched detection and track is above a certain threshold (d), the detected object is initiated as a new track. Kalman filter coupled with the Hungarian algorithm for association, and Thirdly, we introduce a new parameter that takes into account the abnormalities in the orientation of a vehicle during a collision. All the experiments were conducted on Intel(R) Xeon(R) CPU @ 2.30GHz with NVIDIA Tesla K80 GPU, 12GB VRAM, and 12GB Main Memory (RAM). The appearance distance is calculated based on the histogram correlation between and object oi and a detection oj as follows: where CAi,j is a value between 0 and 1, b is the bin index, Hb is the histogram of an object in the RGB color-space, and H is computed as follows: in which B is the total number of bins in the histogram of an object ok. A tag already exists with the provided branch name. The total cost function is used by the Hungarian algorithm [15] to assign the detected objects at the current frame to the existing tracks. The Acceleration Anomaly () is defined to detect collision based on this difference from a pre-defined set of conditions. Otherwise, in case of no association, the state is predicted based on the linear velocity model. All the data samples that are tested by this model are CCTV videos recorded at road intersections from different parts of the world. In section II, the major steps of the proposed accident detection framework, including object detection (section II-A), object tracking (section II-B), and accident detection (section II-C) are discussed. This approach may effectively determine car accidents in intersections with normal traffic flow and good lighting conditions. This paper presents a new efficient framework for accident detection at intersections for traffic surveillance applications. The overlap of bounding boxes of vehicles, Determining Trajectory and their angle of intersection, Determining Speed and their change in acceleration. The object detection and object tracking modules are implemented asynchronously to speed up the calculations. 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. Real-time Near Accident Detection in Traffic Video, COLLIDE-PRED: Prediction of On-Road Collision From Surveillance Videos, Deep4Air: A Novel Deep Learning Framework for Airport Airside However, it suffers a major drawback in accurate predictions when determining accidents in low-visibility conditions, significant occlusions in car accidents, and large variations in traffic patterns [15]. They are also predicted to be the fifth leading cause of human casualties by 2030 [13]. The object trajectories To use this project Python Version > 3.6 is recommended. All the data samples that are tested by this model are CCTV videos recorded at road intersections from different parts of the world. Our parameters ensure that we are able to determine discriminative features in vehicular accidents by detecting anomalies in vehicular motion that are detected by the framework. In addition, large obstacles obstructing the field of view of the cameras may affect the tracking of vehicles and in turn the collision detection. Add a We estimate the collision between two vehicles and visually represent the collision region of interest in the frame with a circle as show in Figure 4. In order to efficiently solve the data association problem despite challenging scenarios, such as occlusion, false positive or false negative results from the object detection, overlapping objects, and shape changes, we design a dissimilarity cost function that employs a number of heuristic cues, including appearance, size, intersection over union (IOU), and position. Nowadays many urban intersections are equipped with surveillance cameras connected to traffic management systems. 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. detection of road accidents is proposed. 5. This method ensures that our approach is suitable for real-time accident conditions which may include daylight variations, weather changes and so on. This approach may effectively determine car accidents in intersections with normal traffic flow and good lighting conditions. detection based on the state-of-the-art YOLOv4 method, object tracking based on This paper introduces a framework based on computer vision that can detect road traffic crashes (RCTs) by using the installed surveillance/CCTV camera and report them to the emergency in real-time with the exact location and time of occurrence of the accident. In computer vision, anomaly detection is a sub-field of behavior understanding from surveillance scenes. Hence, a more realistic data is considered and evaluated in this work compared to the existing literature as given in Table I. We store this vector in a dictionary of normalized direction vectors for each tracked object if its original magnitude exceeds a given threshold. This paper proposes a CCTV frame-based hybrid traffic accident classification . after an overlap with other vehicles. What is Accident Detection System? 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 neck refers to the path aggregation network (PANet) and spatial attention module and the head is the dense prediction block used for bounding box localization and classification. 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 Trajectory Anomaly () is determined from the angle of intersection of the trajectories of vehicles () upon meeting the overlapping condition C1. Leaving abandoned objects on the road for long periods is dangerous, so . 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. Build a Vehicle Detection System using OpenCV and Python We are all set to build our vehicle detection system! Computer vision-based accident detection through video surveillance has become a beneficial but daunting task. 2020, 2020. In case the vehicle has not been in the frame for five seconds, we take the latest available past centroid. Here, we consider 1 and 2 to be the direction vectors for each of the overlapping vehicles respectively. Additionally, the Kalman filter approach [13]. This section provides details about the three major steps in the proposed accident detection framework. Computer vision-based accident detection through video surveillance has become a beneficial but daunting task. Vision-based frameworks for Object Detection, Multiple Object Tracking, and Traffic Near Accident Detection are important applications of Intelligent Transportation System, particularly in video surveillance and etc. Section V illustrates the conclusions of the experiment and discusses future areas of exploration. The speed s of the tracked vehicle can then be estimated as follows: where fps denotes the frames read per second and S is the estimated vehicle speed in kilometers per hour. The following are the steps: The centroid of the objects are determined by taking the intersection of the lines passing through the mid points of the boundary boxes of the detected vehicles. at intersections for traffic surveillance applications. 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. If (L H), is determined from a pre-defined set of conditions on the value of . 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. Consider a, b to be the bounding boxes of two vehicles A and B. The layout of the rest of the paper is as follows. 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. 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 repository majorly explores how CCTV can detect these accidents with the help of Deep Learning. Before running the program, you need to run the accident-classification.ipynb file which will create the model_weights.h5 file. The size dissimilarity is calculated based on the width and height information of the objects: where w and h denote the width and height of the object bounding box, respectively. We can observe that each car is encompassed by its bounding boxes and a mask. arXiv Vanity renders academic papers from The proposed framework capitalizes on Mask R-CNN for accurate object detection followed by an efficient centroid based object tracking algorithm for surveillance footage. Vehicular Traffic has become a substratal part of peoples lives today and it affects numerous human activities and services on a diurnal basis. 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. 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. Section IV contains the analysis of our experimental results. The Acceleration Anomaly () is defined to detect collision based on this difference from a pre-defined set of conditions. 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. This paper introduces a solution which uses state-of-the-art supervised deep learning framework [4] to detect many of the well-identified road-side objects trained on well developed training sets[9]. Hence, effectual organization and management of road traffic is vital for smooth transit, especially in urban areas where people commute customarily. Mask R-CNN not only provides the advantages of Instance Segmentation but also improves the core accuracy by using RoI Align algorithm. The index i[N]=1,2,,N denotes the objects detected at the previous frame and the index j[M]=1,2,,M represents the new objects detected at the current frame. Want to hear about new tools we're making? Video processing was done using OpenCV4.0. Experimental evaluations demonstrate the feasibility of our method in real-time applications of traffic management. Abstract: In Intelligent Transportation System, real-time systems that monitor and analyze road users become increasingly critical as we march toward the smart city era. 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. Section V illustrates the conclusions of the experiment and discusses future areas of exploration. Open navigation menu. In later versions of YOLO [22, 23] multiple modifications have been made in order to improve the detection performance while decreasing the computational complexity of the method. We will discuss the use of and introduce a new parameter to describe the individual occlusions of a vehicle after a collision in Section III-C. A predefined number (B. ) The use of change in Acceleration (A) to determine vehicle collision is discussed in Section III-C. The first part takes the input and uses a form of gray-scale image subtraction to detect and track vehicles. The experimental results are reassuring and show the prowess of the proposed framework. 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.

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. Nowadays many urban intersections are equipped with surveillance cameras connected to traffic management systems. This section describes our proposed framework given in Figure 2. Accordingly, our focus is on the side-impact collisions at the intersection area where two or more road-users collide at a considerable angle. Then, we determine the angle between trajectories by using the traditional formula for finding the angle between the two direction vectors. is used as the estimation model to predict future locations of each detected object based on their current location for better association, smoothing trajectories, and predict missed tracks. These object pairs can potentially engage in a conflict and they are therefore, chosen for further analysis. If nothing happens, download Xcode and try again. The dataset includes day-time and night-time videos of various challenging weather and illumination conditions. The next criterion in the framework, C3, is to determine the speed of the vehicles.

Mask R-CNN for accurate object detection followed by an efficient centroid 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. Once the vehicles are assigned an individual centroid, the following criteria are used to predict the occurrence of a collision as depicted in Figure 2. applied for object association to accommodate for occlusion, overlapping 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. We can minimize this issue by using CCTV accident detection. Recently, traffic accident detection is becoming one of the interesting fields due to its tremendous application potential in Intelligent . 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. The video clips are trimmed down to approximately 20 seconds to include the frames with accidents.
