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. 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. The layout of the rest of the paper is as follows. Section III provides details about the collected dataset and experimental results and the paper is concluded in section section IV. 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. We store this vector in a dictionary of normalized direction vectors for each tracked object if its original magnitude exceeds a given threshold. This could raise false alarms, that is why the framework utilizes other criteria in addition to assigning nominal weights to the individual criteria. Results, Statistics and Comparison with Existing models, F. Baselice, G. Ferraioli, G. Matuozzo, V. Pascazio, and G. Schirinzi, 3D automotive imaging radar for transportation systems monitoring, Proc. The probability of an accident is determined based on speed and trajectory anomalies in a vehicle after an overlap with other vehicles. Video processing was done using OpenCV4.0. The proposed framework is purposely designed with efficient algorithms in order to be applicable in real-time traffic monitoring systems. 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. An accident Detection System is designed to detect accidents via video or CCTV footage. The performance is compared to other representative methods in table I.

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. 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 velocity components are updated when a detection is associated to a target. 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. 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. We then determine the magnitude of the vector, , as shown in Eq. 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. 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. This paper introduces a solution which uses state-of-the-art supervised deep learning framework. 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 process used to determine, where the bounding boxes of two vehicles overlap goes as follow: The overlap of bounding boxes of vehicles, Determining Trajectory and their angle of intersection, Determining Speed and their change in acceleration.

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]. 5. 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. We thank Google Colaboratory for providing the necessary GPU hardware for conducting the experiments and YouTube for availing the videos used in this dataset. To enable the line drawing feature, we need to select 'Region of interest' item from the 'Analyze' option (Figure-4). There was a problem preparing your codespace, please try again. The magenta line protruding from a vehicle depicts its trajectory along the direction. 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 magenta line protruding from a vehicle depicts its trajectory along the direction. Sign up to our mailing list for occasional updates. The second step is to track the movements of all interesting objects that are present in the scene to monitor their motion patterns. 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]. 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. Though these given approaches keep an accurate track of motion of the vehicles but perform poorly in parametrizing the criteria for accident detection. 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. Consider a, b to be the bounding boxes of two vehicles A and B. The efficacy of the proposed approach is due to consideration of the diverse factors that could result in a collision. detection based on the state-of-the-art YOLOv4 method, object tracking based on 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. Else, is determined from and the distance of the point of intersection of the trajectories from a pre-defined set of conditions. If you find a rendering bug, file an issue on GitHub. , to locate and classify the road-users at each video frame. Annually, human casualties and damage of property is skyrocketing in proportion to the number of vehicular collisions and production of vehicles [14]. Additionally, it keeps track of the location of the involved road-users after the conflict has happened. 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. Then, we determine the angle between trajectories by using the traditional formula for finding the angle between the two direction vectors. 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. Even though their second part is a robust way of ensuring correct accident detections, their first part of the method faces severe challenges in accurate vehicular detections such as, in the case of environmental objects obstructing parts of the screen of the camera, or similar objects overlapping their shadows and so on. A sample of the dataset is illustrated in Figure 3. Current traffic management technologies heavily rely on human perception of the footage that was captured. 9. 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 is based on local features such as trajectory intersection, velocity calculation and their anomalies. 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 incorporation of multiple parameters to evaluate the possibility of an accident amplifies the reliability of our system. The dataset includes day-time and night-time videos of various challenging weather and illumination conditions. This paper presents a new efficient framework for accident detection at intersections for traffic surveillance applications. The third step in the framework involves motion analysis and applying heuristics to detect different types of trajectory conflicts that can lead to accidents. Kalman filter coupled with the Hungarian algorithm for association, and One of the solutions, proposed by Singh et al. 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 approach may effectively determine car accidents in intersections with normal traffic flow and good lighting conditions. Road accidents are a significant problem for the whole world. Nowadays many urban intersections are equipped with surveillance cameras connected to traffic management systems. A score which is greater than 0.5 is considered as a vehicular accident else it is discarded. 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 use of change in Acceleration (A) to determine vehicle collision is discussed in Section III-C. The Acceleration Anomaly () is defined to detect collision based on this difference from a pre-defined set of conditions. 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. to use Codespaces. The incorporation of multiple parameters to evaluate the possibility of an accident amplifies the reliability of our system. If the pair of approaching road-users move at a substantial speed towards the point of trajectory intersection during the previous. Anomalies are typically aberrations of scene entities (people, vehicles, environment) and their interactions from normal behavior. You signed in with another tab or window. 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. A popular . 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. Since we are focusing on a particular region of interest around the detected, masked vehicles, we could localize the accident events. The proposed framework provides a robust at: http://github.com/hadi-ghnd/AccidentDetection. 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 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. De-register objects which havent been visible in the current field of view for a predefined number of frames in succession. The existing approaches are optimized for a single CCTV camera through parameter customization. We then determine the Gross Speed (Sg) from centroid difference taken over the Interval of five frames using Eq.

Baselice, G. Ferraioli, G. Matuozzo, V. Pascazio, and G. Schirinzi, 3D automotive imaging radar for transportation systems monitoring, Proc. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. 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. 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. applications of traffic surveillance. A new cost function is As a result, numerous approaches have been proposed and developed to solve this problem. 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. The average processing speed is 35 frames per second (fps) which is feasible for real-time applications. Automatic detection of traffic accidents is an important emerging topic in traffic monitoring systems. 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. 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. computer vision techniques can be viable tools for automatic accident 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. surveillance cameras connected to traffic management systems. This method ensures that our approach is suitable for real-time accident conditions which may include daylight variations, weather changes and so on. 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. 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. The dataset includes accidents in various ambient conditions such as harsh sunlight, daylight hours, snow and night hours. However, the novelty of the proposed framework is in its ability to work with any CCTV camera footage. 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. As a result, numerous approaches have been proposed and developed to solve this problem. This framework was found effective and paves the way to the development of general-purpose vehicular accident detection algorithms in real-time. conditions such as broad daylight, low visibility, rain, hail, and snow using 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. All the data samples that are tested by this model are CCTV videos recorded at road intersections from different parts of the world. Papers With Code is a free resource with all data licensed under. In particular, trajectory conflicts, sign in Add a Vehicular Traffic has become a substratal part of peoples lives today and it affects numerous human activities and services on a diurnal basis. This could raise false alarms, that is why the framework utilizes other criteria in addition to assigning nominal weights to the individual criteria. The Scaled Speeds of the tracked vehicles are stored in a dictionary for each frame. 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. 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. Accident Detection, Mask R-CNN, Vehicular Collision, Centroid based Object Tracking, Earnest Paul Ijjina1 Additionally, despite all the efforts in preventing hazardous driving behaviors, running the red light is still common. Mask R-CNN for accurate object detection followed by an efficient centroid An accident Detection System is designed to detect accidents via video or CCTV footage. Keyword: detection Understanding Policy and Technical Aspects of AI-Enabled Smart Video Surveillance to Address Public Safety. This is done for both the axes. A score which is greater than 0.5 is considered as a vehicular accident else it is discarded. The recent motion patterns of each pair of close objects are examined in terms of speed and moving direction. 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. Description Accident Detection in Traffic Surveillance using opencv Computer vision-based accident detection through video surveillance has become a beneficial but daunting task. However, there can be several cases in which the bounding boxes do overlap but the scenario does not necessarily lead to an accident. This is done for both the axes. Build a Vehicle Detection System using OpenCV and Python We are all set to build our vehicle detection system! We determine the speed of the vehicle in a series of steps. To contribute to this project, knowledge of basic python scripting, Machine Learning, and Deep Learning will help. However, extracting useful information from the detected objects and determining the occurrence of traffic accidents are usually difficult. 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. The proposed framework 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]. 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 proposed framework capitalizes on Mask R-CNN for accurate object detection followed by an efficient centroid based object tracking algorithm for surveillance footage. 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. Accordingly, our focus is on the side-impact collisions at the intersection area where two or more road-users collide at a considerable angle. after an overlap with other vehicles. In addition, large obstacles obstructing the field of view of the cameras may affect the tracking of vehicles and in turn the collision detection. road-traffic CCTV surveillance footage. Note: This project requires a camera. In this . The layout of the rest of the paper is as follows. Section IV contains the analysis of our experimental results. 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. Another factor to account for in the detection of accidents and near-accidents is the angle of collision. If the boxes intersect on both the horizontal and vertical axes, then the boundary boxes are denoted as intersecting. We will be using the computer vision library OpenCV (version - 4.0.0) a lot in this implementation. The trajectories of each pair of close road-users are analyzed with the purpose of detecting possible anomalies that can lead to accidents.
