In addition, large obstacles obstructing the field of view of the cameras may affect the tracking of vehicles and in turn the collision detection. We can minimize this issue by using CCTV accident detection. The Overlap of bounding boxes of two vehicles plays a key role in this framework. 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. The proposed framework achieved a detection rate of 71 % calculated using Eq. surveillance cameras connected to traffic management systems. Mask R-CNN for accurate object detection followed by an efficient centroid In section II, the major steps of the proposed accident detection framework, including object detection (section II-A), object tracking (section II-B), and accident detection (section II-C) are discussed. 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]. The robustness In this paper, a neoteric framework for detection of road accidents is proposed. 8 and a false alarm rate of 0.53 % calculated using Eq. Annually, human casualties and damage of property is skyrocketing in proportion to the number of vehicular collisions and production of vehicles [14]. There was a problem preparing your codespace, please try again. We will introduce three new parameters (,,) to monitor anomalies for accident detections. 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]. After that administrator will need to select two points to draw a line that specifies traffic signal. Or, have a go at fixing it yourself the renderer is open source! Sign up to our mailing list for occasional updates. 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. 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. All programs were written in Python3.5 and utilized Keras2.2.4 and Tensorflow1.12.0. Current traffic management technologies heavily rely on human perception of the footage that was captured. However, extracting useful information from the detected objects and determining the occurrence of traffic accidents are usually difficult. 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. All the data samples that are tested by this model are CCTV videos recorded at road intersections from different parts of the world. The existing video-based accident detection approaches use limited number of surveillance cameras compared to the dataset in this work. 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. PDF Abstract Code Edit No code implementations yet. 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. A classifier is trained based on samples of normal traffic and traffic accident. Otherwise, we discard it. , " A vision-based video crash detection framework for mixed traffic flow environment considering low-visibility condition," Journal of advanced transportation, vol. Traffic accidents include different scenarios, such as rear-end, side-impact, single-car, vehicle rollovers, or head-on collisions, each of which contain specific characteristics and motion patterns. In 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. 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. pip install -r requirements.txt. This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. The surveillance videos at 30 frames per second (FPS) are considered. The more different the bounding boxes of object oi and detection oj are in size, the more Ci,jS approaches one. 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. Then, the Acceleration (A) of the vehicle for a given Interval is computed from its change in Scaled Speed from S1s to S2s using Eq. This framework was evaluated on diverse The conflicts among road-users do not always end in crashes, however, near-accident situations are also of importance to traffic management systems as they can indicate flaws associated with the signal control system and/or intersection geometry. to use Codespaces. We then determine the Gross Speed (Sg) from centroid difference taken over the Interval of five frames using Eq. Video processing was done using OpenCV4.0. 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. 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. The average bounding box centers associated to each track at the first half and second half of the f frames are computed. accident detection by trajectory conflict analysis. task. Support vector machine (SVM) [57, 58] and decision tree have been used for traffic accident detection. An accident Detection System is designed to detect accidents via video or CCTV footage. The object detection framework used here is Mask R-CNN (Region-based Convolutional Neural Networks) as seen in Figure. Consider a, b to be the bounding boxes of two vehicles A and B. The neck refers to the path aggregation network (PANet) and spatial attention module and the head is the dense prediction block used for bounding box localization and classification. The first part takes the input and uses a form of gray-scale image subtraction to detect and track vehicles. Drivers caught in a dilemma zone may decide to accelerate at the time of phase change from green to yellow, which in turn may induce rear-end and angle crashes. As illustrated in fig. 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). 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. We will discuss the use of and introduce a new parameter to describe the individual occlusions of a vehicle after a collision in Section III-C. The first part takes the input and uses a form of gray-scale image subtraction to detect and track vehicles. Accordingly, our focus is on the side-impact collisions at the intersection area where two or more road-users collide at a considerable angle. The layout of this paper is as follows. computer vision techniques can be viable tools for automatic accident Accident Detection, Mask R-CNN, Vehicular Collision, Centroid based Object Tracking, Earnest Paul Ijjina1 of IEE Colloquium on Electronics in Managing the Demand for Road Capacity, Proc. 7. Since we are focusing on a particular region of interest around the detected, masked vehicles, we could localize the accident events. The proposed framework capitalizes on Mask R-CNN for accurate object detection followed by an efficient centroid based object tracking algorithm for surveillance footage. All the experiments were conducted on Intel(R) Xeon(R) CPU @ 2.30GHz with NVIDIA Tesla K80 GPU, 12GB VRAM, and 12GB Main Memory (RAM). The surveillance videos at 30 frames per second (FPS) are considered. An automatic accident detection framework provides useful information for adjusting intersection signal operation and modifying intersection geometry in order to defuse severe traffic crashes. These object pairs can potentially engage in a conflict and they are therefore, chosen for further analysis. The proposed framework capitalizes on Mask R-CNN for accurate object detection followed by an efficient centroid based object tracking algorithm for surveillance footage. If (L H), is determined from a pre-defined set of conditions on the value of .

In the event of a collision, a circle encompasses the vehicles that collided is shown. Lastly, we combine all the individually determined anomaly with the help of a function to determine whether or not an accident has occurred. This work is evaluated on vehicular collision footage from different geographical regions, compiled from YouTube. 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. The trajectories of each pair of close road-users are analyzed with the purpose of detecting possible anomalies that can lead to accidents. Pawar K. and Attar V., " Deep learning based detection and localization of road accidents from traffic surveillance videos," ICT Express, 2021. traffic monitoring systems. 2020 IEEE Third International Conference on Artificial Intelligence and Knowledge Engineering (AIKE), Deep spatio-temporal representation for detection of road accidents using stacked autoencoder, 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. Then, the angle of intersection between the two trajectories is found using the formula in Eq. This parameter captures the substantial change in speed during a collision thereby enabling the detection of accidents from its variation. 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. Road accidents are a significant problem for the whole world. 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. Then the approaching angle of the a pair of road-users a and b is calculated as follows: where denotes the estimated approaching angle, ma and mb are the the general moving slopes of the road-users a and b with respect to the origin of the video frame, xta, yta, xtb, ytb represent the center coordinates of the road-users a and b at the current frame, xta and yta are the center coordinates of object a when first observed, xtb and ytb are the center coordinates of object b when first observed, respectively. In addition, large obstacles obstructing the field of view of the cameras may affect the tracking of vehicles and in turn the collision detection. Calculate the Euclidean distance between the centroids of newly detected objects and existing objects. As a result, numerous approaches have been proposed and developed to solve this problem. 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. objects, and shape changes in the object tracking step. If the boxes intersect on both the horizontal and vertical axes, then the boundary boxes are denoted as intersecting. An accident Detection System is designed to detect accidents via video or CCTV footage. Additionally, it performs unsatisfactorily because it relies only on trajectory intersections and anomalies in the traffic flow pattern, which indicates that it wont perform well in erratic traffic patterns and non-linear trajectories. The third step in the framework involves motion analysis and applying heuristics to detect different types of trajectory conflicts that can lead to accidents. We then determine the magnitude of the vector. This is a cardinal step in the framework and it also acts as a basis for the other criteria as mentioned earlier. One of the solutions, proposed by Singh et al. 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. Otherwise, in case of no association, the state is predicted based on the linear velocity model. YouTube with diverse illumination conditions. By taking the change in angles of the trajectories of a vehicle, we can determine this degree of rotation and hence understand the extent to which the vehicle has underwent an orientation change. This paper presents a new efficient framework for accident detection at intersections for traffic surveillance applications. They do not perform well in establishing standards for accident detection as they require specific forms of input and thereby cannot be implemented for a general scenario.

This framework was evaluated on diverse conditions such as broad daylight, low visibility, rain, hail, and snow using the proposed dataset. Computer vision -based accident detection through video surveillance has become a beneficial but daunting task. Scribd is the world's largest social reading and publishing site. dont have to squint at a PDF. At any given instance, the bounding boxes of A and B overlap, if the condition shown in Eq. This paper introduces a solution which uses state-of-the-art supervised deep learning framework. are analyzed in terms of velocity, angle, and distance in order to detect 9. Therefore, computer vision techniques can be viable tools for automatic accident detection. The probability of an The parameters are: When two vehicles are overlapping, we find the acceleration of the vehicles from their speeds captured in the dictionary. The proposed framework The robust tracking method accounts for challenging situations, such as occlusion, overlapping objects, and shape changes in tracking the objects of interest and recording their trajectories. become a beneficial but daunting task. 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. traffic video data show the feasibility of the proposed method in real-time The experimental results are reassuring and show the prowess of the proposed framework. We then determine the Gross Speed (Sg) from centroid difference taken over the Interval of five frames using Eq. The total cost function is used by the Hungarian algorithm [15] to assign the detected objects at the current frame to the existing tracks. Section IV contains the analysis of our experimental results. detect anomalies such as traffic accidents in real time. You signed in with another tab or window. This framework was found effective and paves the way to Before running the program, you need to run the accident-classification.ipynb file which will create the model_weights.h5 file. 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. This framework is based on local features such as trajectory intersection, velocity calculation and their anomalies. 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. The velocity components are updated when a detection is associated to a target. of IEE Seminar on CCTV and Road Surveillance, K. He, G. Gkioxari, P. Dollr, and R. Girshick, Proc. Detection of Rainfall using General-Purpose Open navigation menu. 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. 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. 1 holds true. In this paper, a new framework to detect vehicular collisions is proposed. 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. 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. We will be using the computer vision library OpenCV (version - 4.0.0) a lot in this implementation. A predefined number (B. ) Automatic detection of traffic accidents is an important emerging topic in traffic monitoring systems. This repository majorly explores how CCTV can detect these accidents with the help of Deep Learning. 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. Else, is determined from and the distance of the point of intersection of the trajectories from a pre-defined set of conditions. The average processing speed is 35 frames per second (fps) which is feasible for real-time applications. Additionally, despite all the efforts in preventing hazardous driving behaviors, running the red light is still common. 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. At any given instance, the bounding boxes of A and B overlap, if the condition shown in Eq. This section describes the process of accident detection when the vehicle overlapping criteria (C1, discussed in Section III-B) has been met as shown in Figure 2. The Trajectory Anomaly () is determined from the angle of intersection of the trajectories of vehicles () upon meeting the overlapping condition C1. 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. All the data samples that are tested by this model are CCTV videos recorded at road intersections from different parts of the world. 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. 1 holds true. Therefore, a predefined number f of consecutive video frames are used to estimate the speed of each road-user individually. The proposed framework provides a robust Selecting the region of interest will start violation detection system. We start with the detection of vehicles by using YOLO architecture; The second module is the . 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. Considering the applicability of our method in real-time edge-computing systems, we apply the efficient and accurate YOLOv4 [2] method for object detection. If the bounding boxes of the object pair overlap each other or are closer than a threshold the two objects are considered to be close. after an overlap with other vehicles. The efficacy of the proposed approach is due to consideration of the diverse factors that could result in a collision. arXiv Vanity renders academic papers from However, there can be several cases in which the bounding boxes do overlap but the scenario does not necessarily lead to an accident. We can minimize this issue by using CCTV accident detection. 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. 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. However, the novelty of the proposed framework is in its ability to work with any CCTV camera footage. This framework was evaluated on diverse conditions such as broad daylight, low visibility, rain, hail, and snow using the proposed dataset. 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. 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. 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. Update coordinates of existing objects based on the shortest Euclidean distance from the current set of centroids and the previously stored centroid. Here we employ a simple but effective tracking strategy similar to that of the Simple Online and Realtime Tracking (SORT) approach [1]. The dataset includes day-time and night-time videos of various challenging weather and illumination conditions. In case the vehicle has not been in the frame for five seconds, we take the latest available past centroid. This is done in order to ensure that minor variations in centroids for static objects do not result in false trajectories. Section III delineates the proposed framework of the paper. In this paper, a neoteric framework for detection of road accidents is proposed. Therefore, computer vision techniques can be viable tools for automatic accident detection. De-register objects which havent been visible in the current field of view for a predefined number of frames in succession. The next task in the framework, T2, is to determine the trajectories of the vehicles.

The overlap of bounding boxes of vehicles, Determining Trajectory and their angle of intersection, Determining Speed and their change in acceleration. The Hungarian algorithm [15] is used to associate the detected bounding boxes from frame to frame. The model of computer-assisted analysis of lung ultrasound image is built which has shown great potential in pulmonary condition diagnosis and is also used as an alternative for diagnosis of COVID-19 in a patient. Are you sure you want to create this branch? 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. have demonstrated an approach that has been divided into two parts. These steps involve detecting interesting road-users by applying the state-of-the-art YOLOv4 [2]. Numerous studies have applied computer vision techniques in traffic surveillance systems [26, 17, 9, 7, 6, 25, 8, 3, 10, 24] for various tasks. Road traffic crashes ranked as the 9th leading cause of human loss and account for 2.2 per cent of all casualties worldwide [13]. The proposed framework capitalizes on Mask R-CNN for accurate object detection followed by an efficient centroid based object tracking algorithm for surveillance footage. Let's first import the required libraries and the modules. https://github.com/krishrustagi/Accident-Detection-System.git, To install all the packages required to run this python program The process used to determine, where the bounding boxes of two vehicles overlap goes as follow: This paper presents a new efficient framework for accident detection at intersections for traffic surveillance applications. sign in Another factor to account for in the detection of accidents and near-accidents is the angle of collision. 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. Lastly, we combine all the individually determined anomaly with the help of a function to determine whether or not an accident has occurred. 5. 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 this section, details about the heuristics used to detect conflicts between a pair of road-users are presented. The framework is built of five modules. This section provides details about the three major steps in the proposed accident detection framework. This is accomplished by utilizing a simple yet highly efficient object tracking algorithm known as Centroid Tracking [10]. 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. Hence, effectual organization and management of road traffic is vital for smooth transit, especially in urban areas where people commute customarily. Computer vision-based accident detection through video surveillance has become a beneficial but daunting task. 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.
