This framework was evaluated on diverse conditions such as broad daylight, low visibility, rain, hail, and snow using the proposed dataset. 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. Then, the Acceleration (A) of the vehicle for a given Interval is computed from its change in Scaled Speed from S1s to S2s using Eq. This framework was found effective and paves the way to the development of general-purpose vehicular accident detection algorithms in real-time. De-register objects which havent been visible in the current field of view for a predefined number of frames in succession. 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. 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. A predefined number (B. ) Mask R-CNN for accurate object detection followed by an efficient centroid pip install -r requirements.txt. This results in a 2D vector, representative of the direction of the vehicles motion. Computer vision-based accident detection through video surveillance has become a beneficial but daunting task. The incorporation of multiple parameters to evaluate the possibility of an accident amplifies the reliability of our system. 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). This section describes our proposed framework given in Figure 2. accident is determined based on speed and trajectory anomalies in a vehicle 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. This method ensures that our approach is suitable for real-time accident conditions which may include daylight variations, weather changes and so on. Then the approaching angle of the a pair of road-users a and b is calculated as follows: where denotes the estimated approaching angle, ma and mb are the the general moving slopes of the road-users a and b with respect to the origin of the video frame, xta, yta, xtb, ytb represent the center coordinates of the road-users a and b at the current frame, xta and yta are the center coordinates of object a when first observed, xtb and ytb are the center coordinates of object b when first observed, respectively. 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 layout of this paper is as follows. The second step is to track the movements of all interesting objects that are present in the scene to monitor their motion patterns. including near-accidents and accidents occurring at urban intersections are This is determined by taking the differences between the centroids of a tracked vehicle for every five successive frames which is made possible by storing the centroid of each vehicle in every frame till the vehicles centroid is registered as per the centroid tracking algorithm mentioned previously. The existing video-based accident detection approaches use limited number of surveillance cameras compared to the dataset in this work. Next, we normalize the speed of the vehicle irrespective of its distance from the camera using Eq. The layout of the rest of the paper is as follows. The process used to determine, where the bounding boxes of two vehicles overlap goes as follow: Road accidents are a significant problem for the whole world. Considering the applicability of our method in real-time edge-computing systems, we apply the efficient and accurate YOLOv4 [2] method for object detection. A classifier is trained based on samples of normal traffic and traffic accident. 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. Otherwise, we discard it. We find the change in accelerations of the individual vehicles by taking the difference of the maximum acceleration and average acceleration during overlapping condition (C1). consists of three hierarchical steps, including efficient and accurate object 7. 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. . 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. method to achieve a high Detection Rate and a low False Alarm Rate on general of World Congress on Intelligent Control and Automation, Y. Ki, J. Choi, H. Joun, G. Ahn, and K. Cho, Real-time estimation of travel speed using urban traffic information system and cctv, Proc. We estimate , the interval between the frames of the video, using the Frames Per Second (FPS) as given in Eq. 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 We then normalize this vector by using scalar division of the obtained vector by its magnitude. 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. 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. Experimental evaluations demonstrate the feasibility of our method in real-time applications of traffic management. 5. In this paper, a neoteric framework for detection of road accidents is proposed. 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. A new set of dissimilarity measures are designed and used by the Hungarian algorithm [15] for object association coupled with the Kalman filter approach [13]. If the boxes intersect on both the horizontal and vertical axes, then the boundary boxes are denoted as intersecting. This framework was evaluated on diverse The overlap of bounding boxes of vehicles, Determining Trajectory and their angle of intersection, Determining Speed and their change in acceleration. Detection of Rainfall using General-Purpose A score which is greater than 0.5 is considered as a vehicular accident else it is discarded. This is the key principle for detecting an accident. The Trajectory Anomaly () is determined from the angle of intersection of the trajectories of vehicles () upon meeting the overlapping condition C1. A new cost function is If nothing happens, download Xcode and try again. This is a cardinal step in the framework and it also acts as a basis for the other criteria as mentioned earlier. Edit social preview. 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. 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. surveillance cameras connected to traffic management systems. The existing approaches are optimized for a single CCTV camera through parameter customization. This method ensures that our approach is suitable for real-time accident conditions which may include daylight variations, weather changes and so on. conditions such as broad daylight, low visibility, rain, hail, and snow using The magenta line protruding from a vehicle depicts its trajectory along the 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. We then display this vector as trajectory for a given vehicle by extrapolating it. Other dangerous behaviors, such as sudden lane changing and unpredictable pedestrian/cyclist movements at the intersection, may also arise due to the nature of traffic control systems or intersection geometry. We used a desktop with a 3.4 GHz processor, 16 GB RAM, and an Nvidia GTX-745 GPU, to implement our proposed method. This work is evaluated on vehicular collision footage from different geographical regions, compiled from YouTube. As a result, numerous approaches have been proposed and developed to solve this problem. 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.

This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. have demonstrated an approach that has been divided into two parts. Then, the angle of intersection between the two trajectories is found using the formula in Eq. Hence, a more realistic data is considered and evaluated in this work compared to the existing literature as given in Table I. 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). Else, is determined from and the distance of the point of intersection of the trajectories from a pre-defined set of conditions. Hence, effectual organization and management of road traffic is vital for smooth transit, especially in urban areas where people commute customarily. 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. The spatial resolution of the videos used in our experiments is 1280720 pixels with a frame-rate of 30 frames per seconds. Consider a, b to be the bounding boxes of two vehicles A and B. 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. Computer vision-based accident detection through video surveillance has Recently, traffic accident detection is becoming one of the interesting fields due to its tremendous application potential in Intelligent . The surveillance videos at 30 frames per second (FPS) are considered. This work is evaluated on vehicular collision footage from different geographical regions, compiled from YouTube. Then, to run this python program, you need to execute the main.py python file. In the event of a collision, a circle encompasses the vehicles that collided is shown. In addition, large obstacles obstructing the field of view of the cameras may affect the tracking of vehicles and in turn the collision detection. This is done for both the axes. 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 found effective and paves the way to the development of general-purpose vehicular accident detection algorithms in real-time. 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. arXiv Vanity renders academic papers from traffic video data show the feasibility of the proposed method in real-time 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 variations in the calculated magnitudes of the velocity vectors of each approaching pair of objects that have met the distance and angle conditions are analyzed to check for the signs that indicate anomalies in the speed and acceleration. 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. One of the solutions, proposed by Singh et al. First, the Euclidean distances among all object pairs are calculated in order to identify the objects that are closer than a threshold to each other. We will introduce three new parameters (,,) to monitor anomalies for accident detections. To use this project Python Version > 3.6 is recommended. Selecting the region of interest will start violation detection system. at intersections for traffic surveillance applications. In this paper a new framework is presented for automatic detection of accidents and near-accidents at traffic intersections. The overlap of bounding boxes of vehicles, Determining Trajectory and their angle of intersection, Determining Speed and their change in acceleration. 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). Additionally, we plan to aid the human operators in reviewing past surveillance footages and identifying accidents by being able to recognize vehicular accidents with the help of our approach. 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 velocity components are updated when a detection is associated to a target. You signed in with another tab or window. All the data samples that are tested by this model are CCTV videos recorded at road intersections from different parts of the world. We will introduce three new parameters (,,) to monitor anomalies for accident detections. At any given instance, the bounding boxes of A and B overlap, if the condition shown in Eq. 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. 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]. 5.

The next criterion in the framework, C3, is to determine the speed of the vehicles. However, extracting useful information from the detected objects and determining the occurrence of traffic accidents are usually difficult. 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 2020, 2020. Road accidents are a significant problem for the whole world. The Trajectory Anomaly () is determined from the angle of intersection of the trajectories of vehicles () upon meeting the overlapping condition C1. 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 probability of an accident is . The position dissimilarity is computed in a similar way: where the value of CPi,j is between 0 and 1, approaching more towards 1 when the object oi and detection oj are further. 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. of IEE Colloquium on Electronics in Managing the Demand for Road Capacity, Proc. Section II succinctly debriefs related works and literature. Calculate the Euclidean distance between the centroids of newly detected objects and existing objects. An accident Detection System is designed to detect accidents via video or CCTV footage. This architecture is further enhanced by additional techniques referred to as bag of freebies and bag of specials. Road traffic crashes ranked as the 9th leading cause of human loss and account for 2.2 per cent of all casualties worldwide [13]. Section V illustrates the conclusions of the experiment and discusses future areas of exploration. Currently, I am experimenting with cutting-edge technology to unleash cleaner energy sources to power the world.<br>I have a total of 8 . An automatic accident detection framework provides useful information for adjusting intersection signal operation and modifying intersection geometry in order to defuse severe traffic crashes. We can minimize this issue by using CCTV accident detection. 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. Based on this angle for each of the vehicles in question, we determine the Change in Angle Anomaly () based on a pre-defined set of conditions. In the UAV-based surveillance technology, video segments captured from . 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. These object pairs can potentially engage in a conflict and they are therefore, chosen for further analysis. As illustrated in fig. Many people lose their lives in road accidents. Computer vision applications in intelligent transportation systems (ITS) and autonomous driving (AD) have gravitated towards deep neural network architectures in recent years. This explains the concept behind the working of Step 3. 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. 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. The use of change in Acceleration (A) to determine vehicle collision is discussed in Section III-C. Therefore, computer vision techniques can be viable tools for automatic accident detection. of IEE Seminar on CCTV and Road Surveillance, K. He, G. Gkioxari, P. Dollr, and R. Girshick, Proc. of bounding boxes and their corresponding confidence scores are generated for each cell. This framework was found effective and paves the way to The next task in the framework, T2, is to determine the trajectories of the vehicles. Additionally, it keeps track of the location of the involved road-users after the conflict has happened. They do not perform well in establishing standards for accident detection as they require specific forms of input and thereby cannot be implemented for a general scenario. This approach may effectively determine car accidents in intersections with normal traffic flow and good lighting conditions. The framework integrates three major modules, including object detection based on YOLOv4 method, a tracking method based on Kalman filter and Hungarian algorithm with a new cost function, and an accident detection module to analyze the extracted trajectories for anomaly detection. 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. The second part applies feature extraction to determine the tracked vehicles acceleration, position, area, and direction. 1 holds true. 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. 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]. Since we are focusing on a particular region of interest around the detected, masked vehicles, we could localize the accident events. 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]. for Vessel Traffic Surveillance in Inland Waterways, Traffic-Net: 3D Traffic Monitoring Using a Single Camera, https://www.aicitychallenge.org/2022-data-and-evaluation/. The next task in the framework, T2, is to determine the trajectories of the vehicles. Support vector machine (SVM) [57, 58] and decision tree have been used for traffic accident detection. 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. YouTube with diverse illumination conditions. So make sure you have a connected camera to your device. This section describes our proposed framework given in Figure 2. We then determine the Gross Speed (Sg) from centroid difference taken over the Interval of five frames using Eq. accident detection by trajectory conflict analysis. detection. arXiv as responsive web pages so you An automatic accident detection framework provides useful information for adjusting intersection signal operation and modifying intersection geometry in order to defuse severe traffic crashes. detection based on the state-of-the-art YOLOv4 method, object tracking based on Before running the program, you need to run the accident-classification.ipynb file which will create the model_weights.h5 file. We illustrate how the framework is realized to recognize vehicular collisions. Section IV contains the analysis of our experimental results. Traffic accidents include different scenarios, such as rear-end, side-impact, single-car, vehicle rollovers, or head-on collisions, each of which contain specific characteristics and motion patterns. In the event of a collision, a circle encompasses the vehicles that collided is shown. This paper presents a new efficient framework for accident detection at intersections for traffic surveillance applications. Another factor to account for in the detection of accidents and near-accidents is the angle of collision. A vision-based real time traffic accident detection method to extract foreground and background from video shots using the Gaussian Mixture Model to detect vehicles; afterwards, the detected vehicles are tracked based on the mean shift algorithm. Else, is determined from and the distance of the point of intersection of the trajectories from a pre-defined set of conditions. Additionally, despite all the efforts in preventing hazardous driving behaviors, running the red light is still common. Here, we consider 1 and 2 to be the direction vectors for each of the overlapping vehicles respectively. A tag already exists with the provided branch name.
