To analyze several traffic indices dynamically and explore the relationship among the indices, a model for multi-lane freeway traffic based on Cellular Automata (CA) theory is proposed in this paper. In the proposed model, vehicle movement is categorized into cellular behavior as chasing, overtaking, changing lane, accelerating and decelerating, cellular status is categorized into velocity change...
Vehicle detection and tracking plays an effective and significant role in the area of traffic surveillance system where efficient traffic management and safety is the main concern. In this paper, we discuss and address the issue of detecting vehicle / traffic data from video frames. Although various researches have been done in this area and many methods have been implemented, still this area has...
This paper introduces a system for chaotic traffic control; the proposed system is a simple, sophisticated and robust version of the Intelligent Traffic Light Flow Control System Using Wireless Sensors Networks proposed by Khalil M. et al. The proposed system adopts a simple approach by adding more Traffic Sensing Nodes [TSN] and distributing them in a matrix layout covering the road bed. In addition...
The increase of vehicle numbers in recent decades resulted in road traffic congestion problems. Such congestions are a characteristic of densely populated urban areas and occur daily during morning and afternoon rush hours. Urban areas have been suffering from the lack of space needed to build new road infrastructure. The traffic congestion problem can be solved by applying new traffic control approaches...
CORSIM short for corridor simulation was developed and is maintained by the Federal Highway Administration. It is a microscopic simulation model designed for the analysis of freeways, urban streets, and corridors or networks. The model includes two predecessor models: FRESIM and NETSIM. FRESIM is a microscopic model of freeway traffic, and NETSIM is a model of urban street traffic. CORSIM has a capability...
Transportation system management and traveler information systems evolve with the development of data communications and traffic simulations. Variety of roadside and mobile sensing platforms will be deployed to allow communication between vehicles with Dedicated Short Range Communications (DSRC). Traffic data received from moving vehicles will be transmitted to each individual vehicle and traffic...
Traffic simulations are being increasingly utilized as transportation systems have become more complex and congested. However, most simulation models have limitations in overcapacity demand conditions. When traffic in a congested area "fills" the available roadway space additional traffic demand may never be allowed to enter the network. The intent of this paper is to explore one possible...
Under the big data background, the massive traffic data provide the data to improve traffic control methods and put forward higher requirements for the accuracy of the traffic signal control. In this paper, we analysis the influence on green wave tape by queue length of vehicles through congestion data and sensor data on road, draw a queue dissipated model and import it into MAXBAND model. Then present...
Extended Floating Car Data (xFCD) is the fundament for many modern traffic forecast systems. In this paper, an xFCD source model with different transmission rules for making the data efficiently available at the forecast server by means of Long Term Evolution (LTE) enabled Machine-Type Communication (MTC) is proposed. Thereby, the delay requirements of the sensor data and the channel conditions of...

Accidents in single lane tunnels can be avoided significantly by using an efficient automatic traffic control system for all possible traffic conditions. Here the objective of the proposed system is to control the traffic density on either side of a single lane tunnel and avoid the vehicle collision inside the single lane tunnel. It is assumed that the entry and exit of the tunnel is only for light...
Parallel traffic simulation is a critical component in large-scale traffic simulations and real-time traffic simulations. Dividing workloads evenly to multi-cores and multi-machines is a challenge in parallel traffic simulations. Current researches focus on map decomposition algorithms. However, without effective workload estimation algorithms, map decomposition algorithms tend to output imbalanced...
Traffic Flow Detection plays an important role in the field of Intelligent Transportation Systems (ITS). Traffic flow detection focuses on the detection and segmentation of video object.
