Abstract:

This paper introduces a real-time traffic observation and analysis system empowered by the You Only Look Once (YOLO) object detection model and the Bytetrack algorithm for vehicle tracking. The system is designed to monitor traffic parameters such as vehicle speed, traffic flow rate, and congestion levels using video footage of roadways. YOLO is utilized for real-time object detection. Bytetrack employs the Kalman filter to predict future vehicle positions and association techniques for mapping vehicles across successive frames, facilitating the assignment of tracking IDs. Leveraging the YOLO

Abstract:

Analyze the traffic flow in multi-scale time window of a freeway by using the nonlinear analysis method such as Correlation dimension , recursive map and so on, we find that chaos and fractal still exist in wide observation scales. Traffic flow correlation dimension reduces when the length of time window increases, in the observation scale of minutes. However, traffic flow correlation dimension reduces when the length of time window reduces, in the observation scale of seconds, instead of fractal property disappearance as predicted before. We present that, from the view of prediction, the reco

Abstract:

Generally, congestion occurs mainly in a section where a traffic flow merge or diverge. This congestion decreases the mobility of the roads and causes the increase of the logistics cost, and ultimately it is the main cause of weakening the national competitiveness. Therefore, in this study, we analyzed the decrease effect of service traffic by interrupting once more diverge after diverge again. We analyzed the traffic flow according to the number of interventions when 1,320 veh/h and 1,356 veh/h of traffic entering the main fleet are located in the junction of the Seoul Junction and the West C

Abstract:

Multimodal traffic flow can reflect the health of the transportation system, and its prediction is crucial to urban traffic management. Recent works overemphasize spatio-temporal correlations of traffic flow, ignoring the physical concepts that lead to the generation of observations and their causal relationship. Spatio-temporal correlations are considered unstable under the influence of different conditions, and spurious correlations may exist in observations. In this paper, we analyze the physical concepts affecting the generation of multimode traffic flow from the perspective of the observa

Abstract Identifying the risk of traffic noise is vital in minimizing traffic noise pollution in urban areas. As noise travels in every direction, 3D visualization of traffic noise is essential, which involves visualising traffic noise along the facades of buildings. A standard traffic noise model is necessary to calculate traffic noise levels, as several factors affect traffic noise. Moreover, designing noise observation points in 3D and spatial interpolation play significant roles in 3D noise visualisation. Therefore, this study demonstrates the results by elaborating on the spatial interpol

Abstract:

Intelligent traffic control is an important issue of the modern transportation system. However, in large-scale urban transportation systems, traditional centralized coordination methods suffer bottlenecks in both communication and computation. Decentralized control is hard if there is very limited observation to the whole network as evidences to support joint traffic coordination decisions. In this paper, we proposed a novel decentralized, multiagent based approach for massive traffic lights coordination to promote the large-scale green transportation. Considering that only the traffic from th

Belmera toll road in North Sumatra was the first toll road, links Belawan-Medan-Tanjung Morawa. The aim of this research is to find the relationship model between speed, density and volume on Belmera toll road based on a traffic study. The traffic study which embodies volume study and the speed of vehicles were divided into 5 vehicle classification, into 2 traffic lines (Entrance and Exit Tanjung Morawa’s toll gates), was conducted on Friday and Saturday around the peak hour on each traffic current. The study concluded that Greenberg model is the best approach for traffic current on Belmera to

Abstract:

This study proposes a real-time monitoring method for two-dimensional (2D) networks via the fusion of probe data and a traffic flow model. In the Great East Japan Earthquake occurring on March 11, 2011, there was major traffic congestion as evacuees concentrated in cities on the Sanriku Coast. A tragedy occurred when a tsunami overtook the stuck vehicles. To evacuate safely and efficiently, the state of traffic must be monitored in real time on a 2D network, where all networks are linked. Generally, the traffic state is monitored only at observation points. However, observation data presents t

Abstract:

Abstract Understanding human interactions in today’s transportation system is a prerequisite for developing well-accepted cooperatively interacting autonomous vehicles. This paper is devoted to the two-sided narrow passage scenario and uses trajectory data to investigate drivers’ interaction behavior when encountering each other from opposite directions. Trajectory data of 209 encounters at a road narrowing were analyzed in terms of drivers’ approaching behavior and arrival order. The exploratory analysis has shown that in this specific location an informal traffic rule has developed: It was n

Abstract:

The unsignaled intersection of Jalan H Djole – Jalan Pasar Lama in Bekasi City is a densely populated commercial area with high economic activity. The lack of facilities and infrastructure that causes traffic jams at the intersection also raises the potential for conflict. This study aims to analyze the level of service, the type of conflict, and the traffic conflict complexity at an unsignaled intersection. The field survey method obtains primary data on the conflict approach and traffic volume. The analysis showed that the highest traffic volume was 3,810 passenger cars unit/hour with a DS v

Abstract:

This paper presents “Proactive Congestion Notification” (PCN), a congestion-avoidance technique for distributed deep learning (DDL). DDL is widely used to scale out and accelerate deep neural network training. In DDL, each worker trains a copy of the deep learning model with different training inputs and synchronizes the model gradients at the end of each iteration. However, it is well known that the network communication for synchronizing model parameters is the main bottleneck in DDL. Our key observation is that the DDL architecture makes each worker generate burst traffic every iteration, w

Abstract:

Today on the highway, especially on crossing roads, motor vehicle users are increasing, both motorbike and car drivers. Not only that, it can be seen from the number that has increased greatly every day. This situation requires the existence of a time setting, whose purpose is nothing but to reduce congestion to the risk of accidents. Therefore, in this study, a traffic light simulation is controlled by OMRON CP1E-N30SDR-A PLC. Traffic light simulation at the three intersections based on PLC OMRON CP1E-N30SDR-A has been made a traffic light control prototype to set the timing of traffic lights
