This approach may effectively determine car accidents in intersections with normal traffic flow and good lighting conditions. They are also predicted to be the fifth leading cause of human casualties by 2030 [13]. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. All programs were written in Python3.5 and utilized Keras2.2.4 and Tensorflow1.12.0. Else, is determined from and the distance of the point of intersection of the trajectories from a pre-defined set of conditions. To use this project Python Version > 3.6 is recommended. arXiv as responsive web pages so you Otherwise, we discard it. of IEE Seminar on CCTV and Road Surveillance, K. He, G. Gkioxari, P. Dollr, and R. Girshick, Proc. , " A vision-based video crash detection framework for mixed traffic flow environment considering low-visibility condition," Journal of advanced transportation, vol. Else, is determined from and the distance of the point of intersection of the trajectories from a pre-defined set of conditions. The proposed framework capitalizes on Mask R-CNN for accurate object detection followed by an efficient centroid based object tracking algorithm for surveillance footage. This explains the concept behind the working of Step 3. This parameter captures the substantial change in speed during a collision thereby enabling the detection of accidents from its variation. Sign up to our mailing list for occasional updates. We find the average acceleration of the vehicles for 15 frames before the overlapping condition (C1) and the maximum acceleration of the vehicles 15 frames after C1. 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%. 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. The probability of an accident is determined based on speed and trajectory anomalies in a vehicle after an overlap with other vehicles. accident detection by trajectory conflict analysis. 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. have demonstrated an approach that has been divided into two parts. The next criterion in the framework, C3, is to determine the speed of the vehicles. The average bounding box centers associated to each track at the first half and second half of the f frames are computed. Accordingly, our focus is on the side-impact collisions at the intersection area where two or more road-users collide at a considerable angle. 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. dont have to squint at a PDF. 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. However, there can be several cases in which the bounding boxes do overlap but the scenario does not necessarily lead to an accident. 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 is the key principle for detecting an accident. An automatic accident detection framework provides useful information for adjusting intersection signal operation and modifying intersection geometry in order to defuse severe traffic crashes. The dataset includes accidents in various ambient conditions such as harsh sunlight, daylight hours, snow and night hours. Surveillance Cameras, https://lilianweng.github.io/lil-log/assets/images/rcnn-family-summary.png, https://www.asirt.org/safe-travel/road-safety-facts/, https://www.cdc.gov/features/globalroadsafety/index.html. In recent times, vehicular accident detection has become a prevalent field for utilizing computer vision [5] to overcome this arduous task of providing first-aid services on time without the need of a human operator for monitoring such event. Kalman filter coupled with the Hungarian algorithm for association, and Experimental results using real 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 find the average acceleration of the vehicles for 15 frames before the overlapping condition (C1) and the maximum acceleration of the vehicles 15 frames after C1. The probability of an accident is . The Trajectory Anomaly () is determined from the angle of intersection of the trajectories of vehicles () upon meeting the overlapping condition C1. 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]. Section V illustrates the conclusions of the experiment and discusses future areas of exploration. As illustrated in fig. Moreover, Ki et al. 7. Multiple object tracking (MOT) has been intensively studies over the past decades [18] due to its importance in video analytics applications. 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]. Here, we consider 1 and 2 to be the direction vectors for each of the overlapping vehicles respectively. The total cost function is used by the Hungarian algorithm [15] to assign the detected objects at the current frame to the existing tracks. 8 and a false alarm rate of 0.53 % calculated using Eq. 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). Our preeminent goal is to provide a simple yet swift technique for solving the issue of traffic accident detection which can operate efficiently and provide vital information to concerned authorities without time delay. 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. This is done in order to ensure that minor variations in centroids for static objects do not result in false trajectories. 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. 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. applied for object association to accommodate for occlusion, overlapping A score which is greater than 0.5 is considered as a vehicular accident else it is discarded. The layout of this paper is as follows. Section III provides details about the collected dataset and experimental results and the paper is concluded in section section IV. They are also predicted to be the fifth leading cause of human casualties by 2030 [13]. Numerous studies have applied computer vision techniques in traffic surveillance systems [26, 17, 9, 7, 6, 25, 8, 3, 10, 24] for various tasks. 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. In the event of a collision, a circle encompasses the vehicles that collided is shown. objects, and shape changes in the object tracking step. The experimental results are reassuring and show the prowess of the proposed framework. Video processing was done using OpenCV4.0. Currently, most traffic management systems monitor the traffic surveillance camera by using manual perception of the captured footage. 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. Road accidents are a significant problem for the whole world. 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. Anomalies are typically aberrations of scene entities (people, vehicles, environment) and their interactions from normal behavior. Otherwise, in case of no association, the state is predicted based on the linear velocity model. A classifier is trained based on samples of normal traffic and traffic accident. detection of road accidents is proposed. An accident Detection System is designed to detect accidents via video or CCTV footage. 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]. This explains the concept behind the working of Step 3. However, one of the limitation of this work is its ineffectiveness for high density traffic due to inaccuracies in vehicle detection and tracking, that will be addressed in future work. In the event of a collision, a circle encompasses the vehicles that collided is shown. 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. , to locate and classify the road-users at each video frame. The inter-frame displacement of each detected object is estimated by a linear velocity model. 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. The probability of an All the data samples that are tested by this model are CCTV videos recorded at road intersections from different parts of the world. 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. The most common road-users involved in conflicts at intersections are vehicles, pedestrians, and cyclists [30]. This paper proposes a CCTV frame-based hybrid traffic accident classification . 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. The GitHub link contains the source code for this deep learning final year project => Covid-19 Detection in Lungs. 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. 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. This paper presents a new efficient framework for accident detection The second part applies feature extraction to determine the tracked vehicles acceleration, position, area, and direction. The centroid tracking mechanism used in this framework is a multi-step process which fulfills the aforementioned requirements. 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. 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. 2. The object trajectories of IEE Colloquium on Electronics in Managing the Demand for Road Capacity, Proc. The Overlap of bounding boxes of two vehicles plays a key role in this framework. If you find a rendering bug, file an issue on GitHub. Lastly, we combine all the individually determined anomaly with the help of a function to determine whether or not an accident has occurred. 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. 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. The performance is compared to other representative methods in table I. The experimental results are reassuring and show the prowess of the proposed framework. detected with a low false alarm rate and a high detection rate. We can minimize this issue by using CCTV accident detection. This is done for both the axes. The video clips are trimmed down to approximately 20 seconds to include the frames with accidents. This algorithm relies on taking the Euclidean distance between centroids of detected vehicles over consecutive frames. Scribd is the world's largest social reading and publishing site. The process used to determine, where the bounding boxes of two vehicles overlap goes as follow: This repository majorly explores how CCTV can detect these accidents with the help of Deep Learning. 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. All programs were written in Python3.5 and utilized Keras2.2.4 and Tensorflow1.12.0. Multi Deep CNN Architecture, Is it Raining Outside? In the area of computer vision, deep neural networks (DNNs) have been used to analyse visual events by learning the spatio-temporal features from training samples. 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. Google Scholar [30]. As in most image and video analytics systems the first step is to locate the objects of interest in the scene. Our approach included creating a detection model, followed by anomaly detection and . Vehicular Traffic has become a substratal part of peoples lives today and it affects numerous human activities and services on a diurnal basis. The first version of the You Only Look Once (YOLO) deep learning method was introduced in 2015 [21]. We used a desktop with a 3.4 GHz processor, 16 GB RAM, and an Nvidia GTX-745 GPU, to implement our proposed method. after an overlap with other 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]. Import Libraries Import Video Frames And Data Exploration 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 framework is built of five modules. Here we employ a simple but effective tracking strategy similar to that of the Simple Online and Realtime Tracking (SORT) approach [1]. Since we are focusing on a particular region of interest around the detected, masked vehicles, we could localize the accident events. 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). 3. While performance seems to be improving on benchmark datasets, many real-world challenges are yet to be adequately considered in research. Lastly, we combine all the individually determined anomaly with the help of a function to determine whether or not an accident has occurred. for smoothing the trajectories and predicting missed objects. 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. If nothing happens, download GitHub Desktop and try again. Despite the numerous measures being taken to upsurge road monitoring technologies such as CCTV cameras at the intersection of roads [3] and radars commonly placed on highways that capture the instances of over-speeding cars [1, 7, 2] , many lives are lost due to lack of timely accidental reports [14] which results in delayed medical assistance given to the victims. Computer vision-based accident detection through video surveillance has become a beneficial but daunting task. Detection of Rainfall using General-Purpose We can use an alarm system that can call the nearest police station in case of an accident and also alert them of the severity of the accident. for Vessel Traffic Surveillance in Inland Waterways, Traffic-Net: 3D Traffic Monitoring Using a Single Camera, https://www.aicitychallenge.org/2022-data-and-evaluation/. 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). As there may be imperfections in the previous steps, especially in the object detection step, analyzing only two successive frames may lead to inaccurate results. Stay informed on the latest trending ML papers with code, research developments, libraries, methods, and datasets. Since we are focusing on a particular region of interest around the detected, masked vehicles, we could localize the accident events. Nowadays many urban intersections are equipped with based object tracking algorithm for surveillance footage. This method ensures that our approach is suitable for real-time accident conditions which may include daylight variations, weather changes and so on. We determine the speed of the vehicle in a series of steps. Due to the lack of a publicly available benchmark for traffic accidents at urban intersections, we collected 29 short videos from YouTube that contain 24 vehicle-to-vehicle (V2V), 2 vehicle-to-bicycle (V2B), and 3 vehicle-to-pedestrian (V2P) trajectory conflict cases. Add a Though these given approaches keep an accurate track of motion of the vehicles but perform poorly in parametrizing the criteria for accident detection. Using Mask R-CNN we automatically segment and construct pixel-wise masks for every object in the video. 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. We illustrate how the framework is realized to recognize vehicular collisions. Automatic detection of traffic accidents is an important emerging topic in traffic monitoring systems. 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. All the data samples that are tested by this model are CCTV videos recorded at road intersections from different parts of the world. Update coordinates of existing objects based on the shortest Euclidean distance from the current set of centroids and the previously stored centroid. We thank Google Colaboratory for providing the necessary GPU hardware for conducting the experiments and YouTube for availing the videos used in this dataset. In this paper, a neoteric framework for detection of road accidents is proposed. Leaving abandoned objects on the road for long periods is dangerous, so . 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. This framework was found effective and paves the way to the development of general-purpose vehicular accident detection algorithms in real-time. However, extracting useful information from the detected objects and determining the occurrence of traffic accidents are usually difficult. detection. The third step in the framework involves motion analysis and applying heuristics to detect different types of trajectory conflicts that can lead to accidents. 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. In this paper, a new framework to detect vehicular collisions is proposed. 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. In this paper, a neoteric framework for detection of road accidents is proposed. Edit social preview. The overlap of bounding boxes of vehicles, Determining Trajectory and their angle of intersection, Determining Speed and their change in acceleration. 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 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. The parameters are: When two vehicles are overlapping, we find the acceleration of the vehicles from their speeds captured in the dictionary. Video processing was done using OpenCV4.0. Many people lose their lives in road accidents. A predefined number (B. ) The magenta line protruding from a vehicle depicts its trajectory along the direction. The Scaled Speeds of the tracked vehicles are stored in a dictionary for each frame. 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. Note that if the locations of the bounding box centers among the f frames do not have a sizable change (more than a threshold), the object is considered to be slow-moving or stalled and is not involved in the speed calculations. The next task in the framework, T2, is to determine the trajectories of the vehicles. Work fast with our official CLI. Each video clip includes a few seconds before and after a trajectory conflict. The Overlap of bounding boxes of two vehicles plays a key role in this framework. The layout of the rest of the paper is as follows. Over a course of the precedent couple of decades, researchers in the fields of image processing and computer vision have been looking at traffic accident detection with great interest [5]. Computer vision applications in intelligent transportation systems (ITS) and autonomous driving (AD) have gravitated towards deep neural network architectures in recent years. These object pairs can potentially engage in a conflict and they are therefore, chosen for further analysis. 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. In addition, large obstacles obstructing the field of view of the cameras may affect the tracking of vehicles and in turn the collision detection. These steps involve detecting interesting road-users by applying the state-of-the-art YOLOv4 [2]. Typically, anomaly detection methods learn the normal behavior via training. 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). An accident Detection System is designed to detect accidents via video or CCTV footage. We estimate , the interval between the frames of the video, using the Frames Per Second (FPS) as given in Eq. At any given instance, the bounding boxes of A and B overlap, if the condition shown in Eq. In this paper a new framework is presented for automatic detection of accidents and near-accidents at traffic intersections. 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. Computer vision-based accident detection through video surveillance has become a beneficial but daunting task. 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]. Similarly, Hui et al. The object detection and object tracking modules are implemented asynchronously to speed up the calculations.
