In this paper a new framework is presented for automatic detection of accidents and near-accidents at traffic intersections. This framework was evaluated on diverse conditions such as broad daylight, low visibility, rain, hail, and snow using the proposed dataset. 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. 4. A score which is greater than 0.5 is considered as a vehicular accident else it is discarded. At any given instance, the bounding boxes of A and B overlap, if the condition shown in Eq. The more different the bounding boxes of object oi and detection oj are in size, the more Ci,jS approaches one. 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. This framework was evaluated on. The Scaled Speeds of the tracked vehicles are stored in a dictionary for each frame. The Hungarian algorithm [15] is used to associate the detected bounding boxes from frame to frame. The proposed framework capitalizes on This framework was found effective and paves the way to the development of general-purpose vehicular accident detection algorithms in real-time. Learn more. Therefore, computer vision techniques can be viable tools for automatic accident detection. This method ensures that our approach is suitable for real-time accident conditions which may include daylight variations, weather changes and so on. 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 use of change in Acceleration (A) to determine vehicle collision is discussed in Section III-C. 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 paper introduces a solution which uses state-of-the-art supervised deep learning framework. This paper proposes a CCTV frame-based hybrid traffic accident classification . The third step in the framework involves motion analysis and applying heuristics to detect different types of trajectory conflicts that can lead to accidents. Then, to run this python program, you need to execute the main.py python file. Recently, traffic accident detection is becoming one of the interesting fields due to its tremendous application potential in Intelligent . 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. The efficacy of the proposed approach is due to consideration of the diverse factors that could result in a collision. Different heuristic cues are considered in the motion analysis in order to detect anomalies that can lead to traffic accidents. 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. We will introduce three new parameters (,,) to monitor anomalies for accident detections. Calculate the Euclidean distance between the centroids of newly detected objects and existing objects. This is done for both the axes. 8 and a false alarm rate of 0.53 % calculated using Eq. The probability of an accident is . different types of trajectory conflicts including vehicle-to-vehicle, consists of three hierarchical steps, including efficient and accurate object The first part takes the input and uses a form of gray-scale image subtraction to detect and track vehicles. Additionally, the Kalman filter approach [13]. In addition to the mentioned dissimilarity measures, we also use the IOU value to calculate the Jaccard distance as follows: where Box(ok) denotes the set of pixels contained in the bounding box of object k. The overall dissimilarity value is calculated as a weighted sum of the four measures: in which wa, ws, wp, and wk define the contribution of each dissimilarity value in the total cost function. The video clips are trimmed down to approximately 20 seconds to include the frames with accidents. A popular . This framework was found effective and paves the way to Update coordinates of existing objects based on the shortest Euclidean distance from the current set of centroids and the previously stored centroid. 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. Abandoned objects detection is one of the most crucial tasks in intelligent visual surveillance systems, especially in highway scenes [6, 15, 16].Various types of abandoned objects may be found on the road, such as vehicle parts left behind in a car accident, cargo dropped from a lorry, debris dropping from a slope, etc. 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. If nothing happens, download Xcode and try again. This section describes our proposed framework given in Figure 2. 1 holds true. This results in a 2D vector, representative of the direction of the vehicles motion. 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]. We will be using the computer vision library OpenCV (version - 4.0.0) a lot in this implementation. 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. This results in a 2D vector, representative of the direction of the vehicles motion. 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, computer vision techniques can be viable tools for automatic accident detection. including near-accidents and accidents occurring at urban intersections are become a beneficial but daunting task. This paper presents a new efficient framework for accident detection at intersections for traffic surveillance applications. conditions such as broad daylight, low visibility, rain, hail, and snow using 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 can observe that each car is encompassed by its bounding boxes and a mask. computer vision techniques can be viable tools for automatic accident Import Libraries Import Video Frames And Data Exploration 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. Automatic detection of traffic accidents is an important emerging topic in traffic monitoring systems. We can minimize this issue by using CCTV accident detection. 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. 1 holds true. If (L H), is determined from a pre-defined set of conditions on the value of . of IEE Seminar on CCTV and Road Surveillance, K. He, G. Gkioxari, P. Dollr, and R. Girshick, Proc. We estimate , the interval between the frames of the video, using the Frames Per Second (FPS) as given in Eq. 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]. 9. One of the main problems in urban traffic management is the conflicts and accidents occurring at the intersections. Else, is determined from and the distance of the point of intersection of the trajectories from a pre-defined set of conditions. 8 and a false alarm rate of 0.53 % calculated using Eq. The centroid tracking mechanism used in this framework is a multi-step process which fulfills the aforementioned requirements. The incorporation of multiple parameters to evaluate the possibility of an accident amplifies the reliability of our system. Section III delineates the proposed framework of the paper. 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 proposed framework is purposely designed with efficient algorithms in order to be applicable in real-time traffic monitoring systems. 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. https://github.com/krishrustagi/Accident-Detection-System.git, To install all the packages required to run this python program 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. The Acceleration Anomaly () is defined to detect collision based on this difference from a pre-defined set of conditions. Multiple object tracking (MOT) has been intensively studies over the past decades [18] due to its importance in video analytics applications. 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. arXiv as responsive web pages so you 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]. Annually, human casualties and damage of property is skyrocketing in proportion to the number of vehicular collisions and production of vehicles [14]. Though these given approaches keep an accurate track of motion of the vehicles but perform poorly in parametrizing the criteria for accident detection. The dataset is publicly available The proposed framework dont have to squint at a PDF. 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.

The dataset includes accidents in various ambient conditions such as harsh sunlight, daylight hours, snow and night hours. 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. This architecture is further enhanced by additional techniques referred to as bag of freebies and bag of specials. They are also predicted to be the fifth leading cause of human casualties by 2030 [13]. Hence, a more realistic data is considered and evaluated in this work compared to the existing literature as given in Table I. However, the novelty of the proposed framework is in its ability to work with any CCTV camera footage. of IEE Colloquium on Electronics in Managing the Demand for Road Capacity, Proc. 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. 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. Road traffic crashes ranked as the 9th leading cause of human loss and account for 2.2 per cent of all casualties worldwide [13]. 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. applications of traffic surveillance. The inter-frame displacement of each detected object is estimated by a linear velocity model. The family of YOLO-based deep learning methods demonstrates the best compromise between efficiency and performance among object detectors. If (L H), is determined from a pre-defined set of conditions on the value of . detection of road accidents is proposed. Experimental results using real 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 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. Register new objects in the field of view by assigning a new unique ID and storing its centroid coordinates in a dictionary. of the proposed framework is evaluated using video sequences collected from , " A vision-based video crash detection framework for mixed traffic flow environment considering low-visibility condition," Journal of advanced transportation, vol. This is done in order to ensure that minor variations in centroids for static objects do not result in false trajectories. Current traffic management technologies heavily rely on human perception of the footage that was captured. Calculate the Euclidean distance between the centroids of newly detected objects and existing objects. This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. 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, 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. 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. The process used to determine, where the bounding boxes of two vehicles overlap goes as follow: 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. 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 Vision-Based Video Crash Detection Framework for Mixed Traffic Flow Environment Considering Low-Visibility Condition In this paper, a vision-based crash detection framework was proposed to quickly detect various crash types in mixed traffic flow environment, considering low-visibility conditions. 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, have demonstrated an approach that has been divided into two parts. If you find a rendering bug, file an issue on GitHub. 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. Leaving abandoned objects on the road for long periods is dangerous, so . YouTube with diverse illumination conditions. Section II succinctly debriefs related works and literature. 7. 7. Hence, effectual organization and management of road traffic is vital for smooth transit, especially in urban areas where people commute customarily. In particular, trajectory conflicts, De-register objects which havent been visible in the current field of view for a predefined number of frames in succession. This parameter captures the substantial change in speed during a collision thereby enabling the detection of accidents from its variation. accident is determined based on speed and trajectory anomalies in a vehicle Using Mask R-CNN we automatically segment and construct pixel-wise masks for every object in the video. 2. 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.

We then display this vector as trajectory for a given vehicle by extrapolating it. In addition, large obstacles obstructing the field of view of the cameras may affect the tracking of vehicles and in turn the collision detection. 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. The proposed framework provides a robust However, extracting useful information from the detected objects and determining the occurrence of traffic accidents are usually difficult. real-time. In the UAV-based surveillance technology, video segments captured from . Section III delineates the proposed framework of the paper. Our framework is able to report the occurrence of trajectory conflicts along with the types of the road-users involved immediately. 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. Additionally, it keeps track of the location of the involved road-users after the conflict has happened. An automatic accident detection framework provides useful information for adjusting intersection signal operation and modifying intersection geometry in order to defuse severe traffic crashes. 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. Before running the program, you need to run the accident-classification.ipynb file which will create the model_weights.h5 file. Many people lose their lives in road accidents. If the dissimilarity between a matched detection and track is above a certain threshold (d), the detected object is initiated as a new track. The Scaled Speeds of the tracked vehicles are stored in a dictionary for each frame. The Trajectory Anomaly () is determined from the angle of intersection of the trajectories of vehicles () upon meeting the overlapping condition C1. A classifier is trained based on samples of normal traffic and traffic accident. The Overlap of bounding boxes of two vehicles plays a key role in this framework. objects, and shape changes in the object tracking step. The trajectories of each pair of close road-users are analyzed with the purpose of detecting possible anomalies that can lead to accidents. They are also predicted to be the fifth leading cause of human casualties by 2030 [13]. In this . Surveillance, Detection of road traffic crashes based on collision estimation, Blind-Spot Collision Detection System for Commercial Vehicles Using 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. 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]. task. detection based on the state-of-the-art YOLOv4 method, object tracking based on Pawar K. and Attar V., " Deep learning based detection and localization of road accidents from traffic surveillance videos," ICT Express, 2021. In this paper, a new framework to detect vehicular collisions is proposed. 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. From this point onwards, we will refer to vehicles and objects interchangeably. 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. You signed in with another tab or window. Video processing was done using OpenCV4.0. The GitHub link contains the source code for this deep learning final year project => Covid-19 Detection in Lungs. The next task in the framework, T2, is to determine the trajectories of the vehicles. Thirdly, we introduce a new parameter that takes into account the abnormalities in the orientation of a vehicle during a collision. Therefore, detect anomalies such as traffic accidents in real time. This work is evaluated on vehicular collision footage from different geographical regions, compiled from YouTube. Automatic detection of traffic accidents is an important emerging topic in 5. 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 store this vector in a dictionary of normalized direction vectors for each tracked object if its original magnitude exceeds a given threshold. The proposed framework achieved a detection rate of 71 % calculated using Eq. Keyword: detection Understanding Policy and Technical Aspects of AI-Enabled Smart Video Surveillance to Address Public Safety. Accordingly, our focus is on the side-impact collisions at the intersection area where two or more road-users collide at a considerable angle. Computer vision-based accident detection through video surveillance has become a beneficial but daunting task. In this paper, a new framework to detect vehicular collisions is proposed. The magenta line protruding from a vehicle depicts its trajectory along the direction. To use this project Python Version > 3.6 is recommended. This framework was found effective and paves the way to the development of general-purpose vehicular accident detection algorithms in real-time. This framework is based on local features such as trajectory intersection, velocity calculation and their anomalies. Each video clip includes a few seconds before and after a trajectory conflict. 5. 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. Use Git or checkout with SVN using the web URL. 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. Anomalies are typically aberrations of scene entities (people, vehicles, environment) and their interactions from normal behavior. the development of general-purpose vehicular accident detection algorithms in You can also use a downloaded video if not using a camera. 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 thank Google Colaboratory for providing the necessary GPU hardware for conducting the experiments and YouTube for availing the videos used in this dataset. Mask R-CNN for accurate object detection followed by an efficient centroid Annually, human casualties and damage of property is skyrocketing in proportion to the number of vehicular collisions and production of vehicles [14]. These steps involve detecting interesting road-users by applying the state-of-the-art YOLOv4 [2]. Currently, most traffic management systems monitor the traffic surveillance camera by using manual perception of the captured footage. 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. In this paper, a neoteric framework for detection of road accidents is proposed. Edit social preview. As a result, numerous approaches have been proposed and developed to solve this problem.
