applied for object association to accommodate for occlusion, overlapping The experimental results are reassuring and show the prowess of the proposed framework. including near-accidents and accidents occurring at urban intersections are Section III delineates the proposed framework of the paper. Additionally, despite all the efforts in preventing hazardous driving behaviors, running the red light is still common. Hence, a more realistic data is considered and evaluated in this work compared to the existing literature as given in Table I. 1 holds true. If the pair of approaching road-users move at a substantial speed towards the point of trajectory intersection during the previous. https://github.com/krishrustagi/Accident-Detection-System.git, To install all the packages required to run this python program 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]. Section IV contains the analysis of our experimental results. 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. Otherwise, we discard it. 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]. Video processing was done using OpenCV4.0. of the proposed framework is evaluated using video sequences collected from Hence, effectual organization and management of road traffic is vital for smooth transit, especially in urban areas where people commute customarily. All the data samples that are tested by this model are CCTV videos recorded at road intersections from different parts of the world. The process used to determine, where the bounding boxes of two vehicles overlap goes as follow: detection of road accidents is proposed. Video processing was done using OpenCV4.0. 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. The process used to determine, where the bounding boxes of two vehicles overlap goes as follow: 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 video clips are trimmed down to approximately 20 seconds to include the frames with accidents. 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. Section III provides details about the collected dataset and experimental results and the paper is concluded in section section IV. We then display this vector as trajectory for a given vehicle by extrapolating it. This section describes our proposed framework given in Figure 2. Here we employ a simple but effective tracking strategy similar to that of the Simple Online and Realtime Tracking (SORT) approach [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. 4. after an overlap with other vehicles. We will be using the computer vision library OpenCV (version - 4.0.0) a lot in this implementation. Many people lose their lives in road accidents. The layout of the rest of the paper is as follows. The second step is to track the movements of all interesting objects that are present in the scene to monitor their motion patterns. 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. 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). 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). Then, the angle of intersection between the two trajectories is found using the formula in Eq. You can also use a downloaded video if not using a camera. 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). However, the novelty of the proposed framework is in its ability to work with any CCTV camera footage. Pawar K. and Attar V., " Deep learning based detection and localization of road accidents from traffic surveillance videos," ICT Express, 2021. The proposed framework applications of traffic surveillance. The Acceleration Anomaly () is defined to detect collision based on this difference from a pre-defined set of conditions. Our approach included creating a detection model, followed by anomaly detection and . This results in a 2D vector, representative of the direction of the vehicles motion. of IEE Seminar on CCTV and Road Surveillance, K. He, G. Gkioxari, P. Dollr, and R. Girshick, Proc. 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. Computer vision-based accident detection through video surveillance has We store this vector in a dictionary of normalized direction vectors for each tracked object if its original magnitude exceeds a given threshold. 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. If (L H), is determined from a pre-defined set of conditions on the value of . Currently, I am experimenting with cutting-edge technology to unleash cleaner energy sources to power the world.<br>I have a total of 8 . This takes a substantial amount of effort from the point of view of the human operators and does not support any real-time feedback to spontaneous events. We estimate , the interval between the frames of the video, using the Frames Per Second (FPS) as given in Eq. 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. 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. Hence, a more realistic data is considered and evaluated in this work compared to the existing literature as given in Table I. Work fast with our official CLI. 9. A sample of the dataset is illustrated in Figure 3. of IEE Colloquium on Electronics in Managing the Demand for Road Capacity, Proc. 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. Typically, anomaly detection methods learn the normal behavior via training. 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. 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. 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. have demonstrated an approach that has been divided into two parts. However, the novelty of the proposed framework is in its ability to work with any CCTV camera footage. All programs were written in Python3.5 and utilized Keras2.2.4 and Tensorflow1.12.0. arXiv as responsive web pages so you 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. Detection of Rainfall using General-Purpose 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. Once the vehicles have been detected in a given frame, the next imperative task of the framework is to keep track of each of the detected objects in subsequent time frames of the footage. We determine the speed of the vehicle in a series of steps. This is a cardinal step in the framework and it also acts as a basis for the other criteria as mentioned earlier. 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. for Vessel Traffic Surveillance in Inland Waterways, Traffic-Net: 3D Traffic Monitoring Using a Single Camera, https://www.aicitychallenge.org/2022-data-and-evaluation/. Multiple object tracking (MOT) has been intensively studies over the past decades [18] due to its importance in video analytics applications. De-register objects which havent been visible in the current field of view for a predefined number of frames in succession. for smoothing the trajectories and predicting missed objects. The object detection framework used here is Mask R-CNN (Region-based Convolutional Neural Networks) as seen in Figure. So make sure you have a connected camera to your device. of IEE Colloquium on Electronics in Managing the Demand for Road Capacity, Proc. 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. 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. Calculate the Euclidean distance between the centroids of newly detected objects and existing objects. Google Scholar [30]. In addition, large obstacles obstructing the field of view of the cameras may affect the tracking of vehicles and in turn the collision detection. accident detection by trajectory conflict analysis. Leaving abandoned objects on the road for long periods is dangerous, so . Consider a, b to be the bounding boxes of two vehicles A and B. If the boxes intersect on both the horizontal and vertical axes, then the boundary boxes are denoted as intersecting.

An automatic accident detection framework provides useful information for adjusting intersection signal operation and modifying intersection geometry in order to defuse severe traffic crashes. , to locate and classify the road-users at each video frame. A score which is greater than 0.5 is considered as a vehicular accident else it is discarded. The probability of an accident is determined based on speed and trajectory anomalies in a vehicle after an overlap with other vehicles. From this point onwards, we will refer to vehicles and objects interchangeably. 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.

Abrantes, and J. S. Marques, An algorithm for centroid-based tracking of moving objects, Proc. We can observe that each car is encompassed by its bounding boxes and a mask. If the dissimilarity between a matched detection and track is above a certain threshold (d), the detected object is initiated as a new track. This is accomplished by utilizing a simple yet highly efficient object tracking algorithm known as Centroid Tracking [10]. 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. 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. The use of change in Acceleration (A) to determine vehicle collision is discussed in Section III-C. Road accidents are a significant problem for the whole world. 3. The layout of this paper is as follows. This algorithm relies on taking the Euclidean distance between centroids of detected vehicles over consecutive frames. 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. This is achieved with the help of RoI Align by overcoming the location misalignment issue suffered by RoI Pooling which attempts to fit the blocks of the input feature map. 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, suggested an approach which uses the Gaussian Mixture Model (GMM) to detect vehicles and then the detected vehicles are tracked using the mean shift algorithm. Currently, most traffic management systems monitor the traffic surveillance camera by using manual perception of the captured footage. This framework was found effective and paves the way to The experimental results are reassuring and show the prowess of the proposed framework. 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. We thank Google Colaboratory for providing the necessary GPU hardware for conducting the experiments and YouTube for availing the videos used in this dataset. However, there can be several cases in which the bounding boxes do overlap but the scenario does not necessarily lead to an accident. The velocity components are updated when a detection is associated to a target. 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. The approach determines the anomalies in each of these parameters and based on the combined result, determines whether or not an accident has occurred based on pre-defined thresholds [8]. We can observe that each car is encompassed by its bounding boxes and a mask. 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. De-register objects which havent been visible in the current field of view for a predefined number of frames in succession. 9. In this paper, a neoteric framework for detection of road accidents is proposed. Nowadays many urban intersections are equipped with This is the key principle for detecting an 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. Similarly, Hui et al. An accident Detection System is designed to detect accidents via video or CCTV footage. Using Mask R-CNN we automatically segment and construct pixel-wise masks for every object in the video. 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 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. One of the main problems in urban traffic management is the conflicts and accidents occurring at the intersections. To contribute to this project, knowledge of basic python scripting, Machine Learning, and Deep Learning will help. The bounding box centers of each road-user are extracted at two points: (i) when they are first observed and (ii) at the time of conflict with another road-user. The two averaged points p and q are transformed to the real-world coordinates using the inverse of the homography matrix H1, which is calculated during camera calibration [28] by selecting a number of points on the frame and their corresponding locations on the Google Maps [11]. Since we are focusing on a particular region of interest around the detected, masked vehicles, we could localize the accident events. method to achieve a high Detection Rate and a low False Alarm Rate on general 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 trajectory conflicts are detected and reported in real-time with only 2 instances of false alarms which is an acceptable rate considering the imperfections in the detection and tracking results. Thirdly, we introduce a new parameter that takes into account the abnormalities in the orientation of a vehicle during a collision. You signed in with another tab or window. computer vision techniques can be viable tools for automatic accident The Trajectory Anomaly () is determined from the angle of intersection of the trajectories of vehicles () upon meeting the overlapping condition C1. 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. This paper conducted an extensive literature review on the applications of . Road accidents are a significant problem for the whole world. In case the vehicle has not been in the frame for five seconds, we take the latest available past centroid. The incorporation of multiple parameters to evaluate the possibility of an accident amplifies the reliability of our system. In this paper, a neoteric framework for detection of road accidents is proposed. Add a Register new objects in the field of view by assigning a new unique ID and storing its centroid coordinates in a dictionary. 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 paper presents a new efficient framework for accident detection at intersections . 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. We determine the speed of the vehicle in a series of steps. The surveillance videos at 30 frames per second (FPS) are considered. In this paper, a new framework to detect vehicular collisions is proposed. 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. 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 Scaled Speeds of the tracked vehicles are stored in a dictionary for each frame. Once the vehicles have been detected in a given frame, the next imperative task of the framework is to keep track of each of the detected objects in subsequent time frames of the footage. The video clips are trimmed down to approximately 20 seconds to include the frames with accidents. Since we are focusing on a particular region of interest around the detected, masked vehicles, we could localize the accident events. This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. 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. These steps involve detecting interesting road-users by applying the state-of-the-art YOLOv4 [2]. The parameters are: When two vehicles are overlapping, we find the acceleration of the vehicles from their speeds captured in the dictionary. This could raise false alarms, that is why the framework utilizes other criteria in addition to assigning nominal weights to the individual criteria. Update coordinates of existing objects based on the shortest Euclidean distance from the current set of centroids and the previously stored centroid. objects, and shape changes in the object tracking step. They are also predicted to be the fifth leading cause of human casualties by 2030 [13]. This parameter captures the substantial change in speed during a collision thereby enabling the detection of accidents from its variation. 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. This is done in order to ensure that minor variations in centroids for static objects do not result in false trajectories. A tag already exists with the provided branch name. The object detection and object tracking modules are implemented asynchronously to speed up the calculations. 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. Nowadays many urban intersections are equipped with surveillance cameras connected to traffic management systems. Calculate the Euclidean distance between the centroids of newly detected objects and existing objects. 8 and a false alarm rate of 0.53 % calculated using Eq. 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. However, extracting useful information from the detected objects and determining the occurrence of traffic accidents are usually difficult. For static objects do not result in false trajectories of conditions on the shortest distance.
