Consider a, b to be the bounding boxes of two vehicles A and B. Computer vision -based accident detection through video surveillance has become a beneficial but daunting task. A tag already exists with the provided branch name. 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. 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 parameters are: When two vehicles are overlapping, we find the acceleration of the vehicles from their speeds captured in the dictionary. The inter-frame displacement of each detected object is estimated by a linear velocity model. 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]. We used a desktop with a 3.4 GHz processor, 16 GB RAM, and an Nvidia GTX-745 GPU, to implement our proposed method. Keyword: detection Understanding Policy and Technical Aspects of AI-Enabled Smart Video Surveillance to Address Public Safety. 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. different types of trajectory conflicts including vehicle-to-vehicle, 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. accident detection by trajectory conflict analysis. The probability of an accident is determined based on speed and trajectory anomalies in a vehicle after an overlap with other vehicles. Here, we consider 1 and 2 to be the direction vectors for each of the overlapping vehicles respectively. This paper presents a new efficient framework for accident detection Road traffic crashes ranked as the 9th leading cause of human loss and account for 2.2 per cent of all casualties worldwide [13]. In this paper, a new framework to detect vehicular collisions is proposed. the proposed dataset. The most common road-users involved in conflicts at intersections are vehicles, pedestrians, and cyclists [30]. Update coordinates of existing objects based on the shortest Euclidean distance from the current set of centroids and the previously stored centroid. Current traffic management technologies heavily rely on human perception of the footage that was captured. 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. 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. Though these given approaches keep an accurate track of motion of the vehicles but perform poorly in parametrizing the criteria for accident detection. This paper presents a new efficient framework for accident detection at intersections for traffic surveillance applications. 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.

In this paper, a neoteric framework for detection of road accidents is proposed. Automatic detection of traffic accidents is an important emerging topic in Nowadays many urban intersections are equipped with surveillance cameras connected to traffic management systems. 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%. 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. Mask R-CNN not only provides the advantages of Instance Segmentation but also improves the core accuracy by using RoI Align algorithm. De-register objects which havent been visible in the current field of view for a predefined number of frames in succession. Nowadays many urban intersections are equipped with surveillance cameras connected to traffic management systems. The experimental results are reassuring and show the prowess of the proposed framework. Accident Detection, Mask R-CNN, Vehicular Collision, Centroid based Object Tracking, Earnest Paul Ijjina1 The efficacy of the proposed approach is due to consideration of the diverse factors that could result in a collision. 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. Then, we determine the angle between trajectories by using the traditional formula for finding the angle between the two direction vectors. vehicle-to-pedestrian, and vehicle-to-bicycle. for Vessel Traffic Surveillance in Inland Waterways, Traffic-Net: 3D Traffic Monitoring Using a Single Camera, https://www.aicitychallenge.org/2022-data-and-evaluation/. Therefore, a predefined number f of consecutive video frames are used to estimate the speed of each road-user individually. Annually, human casualties and damage of property is skyrocketing in proportion to the number of vehicular collisions and production of vehicles [14]. The proposed framework is purposely designed with efficient algorithms in order to be applicable in real-time traffic monitoring systems. 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. This parameter captures the substantial change in speed during a collision thereby enabling the detection of accidents from its variation. Since here we are also interested in the category of the objects, we employ a state-of-the-art object detection method, namely YOLOv4 [2]. 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 dataset is publicly available 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. The proposed framework If the pair of approaching road-users move at a substantial speed towards the point of trajectory intersection during the previous. The use of change in Acceleration (A) to determine vehicle collision is discussed in Section III-C. 1 holds true. 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. 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. This framework capitalizes on Mask R-CNN for accurate object detection followed by an efficient centroid based object tracking algorithm for surveillance footage to achieve a high Detection Rate and a low False Alarm Rate on general road-traffic CCTV surveillance footage. 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. All the data samples that are tested by this model are CCTV videos recorded at road intersections from different parts of the world. 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. 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 performance is compared to other representative methods in table I. Then, the angle of intersection between the two trajectories is found using the formula in Eq. The layout of the rest of the paper is as follows. 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 first part takes the input and uses a form of gray-scale image subtraction to detect and track vehicles. Video processing was done using OpenCV4.0. This paper introduces a solution which uses state-of-the-art supervised deep learning framework. Logging and analyzing trajectory conflicts, including severe crashes, mild accidents and near-accident situations will help decision-makers improve the safety of the urban intersections. Therefore, computer vision techniques can be viable tools for automatic accident detection. In particular, trajectory conflicts, Kalman filter coupled with the Hungarian algorithm for association, and 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. 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. 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 object detection framework used here is Mask R-CNN (Region-based Convolutional Neural Networks) as seen in Figure 1. 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. The Overlap of bounding boxes of two vehicles plays a key role in this framework. The magenta line protruding from a vehicle depicts its trajectory along the direction. 7. This parameter captures the substantial change in speed during a collision thereby enabling the detection of accidents from its variation.

This work is evaluated on vehicular collision footage from different geographical regions, compiled from YouTube. at: http://github.com/hadi-ghnd/AccidentDetection. In this paper, a neoteric framework for detection of road accidents is proposed. 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. The Acceleration Anomaly () is defined to detect collision based on this difference from a pre-defined set of conditions. The first part takes the input and uses a form of gray-scale image subtraction to detect and track vehicles. 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. The object detection and object tracking modules are implemented asynchronously to speed up the calculations. 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). 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. 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 spatial resolution of the videos used in our experiments is 1280720 pixels with a frame-rate of 30 frames per seconds. Next, we normalize the speed of the vehicle irrespective of its distance from the camera using Eq. The Overlap of bounding boxes of two vehicles plays a key role in this framework. A score which is greater than 0.5 is considered as a vehicular accident else it is discarded. [4]. Or, have a go at fixing it yourself the renderer is open source! 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. Section III delineates the proposed framework of the paper. 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). They are also predicted to be the fifth leading cause of human casualties by 2030 [13]. 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. In the UAV-based surveillance technology, video segments captured from . 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. 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. Though these given approaches keep an accurate track of motion of the vehicles but perform poorly in parametrizing the criteria for accident detection. 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. To contribute to this project, knowledge of basic python scripting, Machine Learning, and Deep Learning will help. The second part applies feature extraction to determine the tracked vehicles acceleration, position, area, and direction. The family of YOLO-based deep learning methods demonstrates the best compromise between efficiency and performance among object detectors. of the proposed framework is evaluated using video sequences collected from 9. Anomalies are typically aberrations of scene entities (people, vehicles, environment) and their interactions from normal behavior. A new cost function is This paper proposes a CCTV frame-based hybrid traffic accident classification . This method ensures that our approach is suitable for real-time accident conditions which may include daylight variations, weather changes and so on. The process used to determine, where the bounding boxes of two vehicles overlap goes as follow: 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. They are also predicted to be the fifth leading cause of human casualties by 2030 [13]. At any given instance, the bounding boxes of A and B overlap, if the condition shown in Eq. The existing approaches are optimized for a single CCTV camera through parameter customization. The probability of an accident is determined based on speed and trajectory anomalies in a vehicle after an overlap with other vehicles. We then normalize this vector by using scalar division of the obtained vector by its magnitude. This architecture is further enhanced by additional techniques referred to as bag of freebies and bag of specials. 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. This approach may effectively determine car accidents in intersections with normal traffic flow and good lighting conditions. Accordingly, our focus is on the side-impact collisions at the intersection area where two or more road-users collide at a considerable angle. Learn more. What is Accident Detection System? One of the main problems in urban traffic management is the conflicts and accidents occurring at the intersections. The process used to determine, where the bounding boxes of two vehicles overlap goes as follow: method to achieve a high Detection Rate and a low False Alarm Rate on general . pip install -r requirements.txt. Typically, anomaly detection methods learn the normal behavior via training. traffic video data show the feasibility of the proposed method in real-time detection of road accidents is proposed. YouTube with diverse illumination conditions. The Trajectory Anomaly () is determined from the angle of intersection of the trajectories of vehicles () upon meeting the overlapping condition C1. 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. This framework was evaluated on diverse conditions such as broad daylight, low visibility, rain, hail, and snow using the proposed dataset. consists of three hierarchical steps, including efficient and accurate object We then display this vector as trajectory for a given vehicle by extrapolating it. Computer vision-based accident detection through video surveillance has become a beneficial but daunting task. This is a cardinal step in the framework and it also acts as a basis for the other criteria as mentioned earlier. 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. 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 results in a 2D vector, representative of the direction of the vehicles motion. 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. 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 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. The video clips are trimmed down to approximately 20 seconds to include the frames with accidents. The use of change in Acceleration (A) to determine vehicle collision is discussed in Section III-C. This framework was found effective and paves the way to the development of general-purpose vehicular accident detection algorithms in real-time. sign in The proposed framework capitalizes on Mask R-CNN for accurate object detection followed by an efficient centroid based object tracking algorithm for surveillance footage. Numerous studies have applied computer vision techniques in traffic surveillance systems [26, 17, 9, 7, 6, 25, 8, 3, 10, 24] for various tasks. 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. 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. After that administrator will need to select two points to draw a line that specifies traffic signal. Nowadays many urban intersections are equipped with 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. arXiv as responsive web pages so you Otherwise, we discard it. road-traffic CCTV surveillance footage. Open navigation menu. Description Accident Detection in Traffic Surveillance using opencv Computer vision-based accident detection through video surveillance has become a beneficial but daunting task. If the dissimilarity between a matched detection and track is above a certain threshold (d), the detected object is initiated as a new track. We then display this vector as trajectory for a given vehicle by extrapolating it. All programs were written in Python3.5 and utilized Keras2.2.4 and Tensorflow1.12.0.
