The main innovative idea of the proposed cyber physical system is step-by-step transfer of traffic lights from the ground to a virtual cloud space for vehicle management, equipped with a mobile gadget or computer, which displays on the screen map, route, coordinates of the road user and real traffic signals. The aim of this paper is to propose and discuss the formal modeling and technical realization...
In this paper the authors present an approach to the interpretation and distribution of geo-referenced information about road events for the purpose of road traffic shaping in the INSIGMA system. Particular focus was paid to the architecture and development of Registration, Distribution and Displaying Road Information on Variable Message Signs that implements the proposed mechanism. Created subsystem...
A smart road infrastructure is proposed to monitor and control traffic in real-time. It uses global positioning and navigation, as well as mobile gadgets and the Internet for improving the quality and safety of vehicle movement and minimization the time and costs. The innovative idea is using a virtual cloud space for vehicle management.
An intellectual (smart) road infrastructure is proposed to monitor and control traffic in real-time through the use of global systems for positioning and navigation, mobile gadgets and the Internet in order improve the quality and safety of vehicle movement, as well as for minimizing the time and costs when vehicles are moved at the specified routes. A set of innovative scientific and technological...
Global warming and its related phenomena such as iceberg melting and sea level rising, is the result of human's penchant to industrial living which leads to increase of greenhouse gas emission. Increase of greenhouse gas inside the atmosphere gets result in Greenhouse effect phenomenon. This problem has received increasing attention from scholars and industries in recent years under name of green...
Wireless technologies can help solve traffic congestions in urban environments, where road infrastructures develop slower than the sometimes exponential growth in the number of cars in traffic. We present a traffic control and congestion avoidance system developed over a vehicular ad-hoc network created between the cars in traffic and the road infrastructure. We propose a solution for monitoring traffic...
Wireless technologies can help solve traffic congestions in urban environments, where road infrastructures develop slower than the sometimes exponential growth in the number of cars in traffic. We present a system for traffic control and congestion avoidance. The system monitors traffic using cars acting as data collectors. It aggregates the monitoring data into a traffic model, further used by cars...
RFID is non-contact automatic identification technology which could be applied to various industries extensively. Accessing the vehicle speed range in freeway, we could use RFID technology to monitor speed of vehicles. Then we could determine whether the vehicles are over speed. Therefore, the use of RFID technology can effectively reduce speeding violations and enhance traffic safety. Its toll is...
The integration of Wireless Communications and Computer Science can lead to the development of advanced systems and services. This paper presents the development of an automated management system for road traffic control in emergency situations. This system consists of a Wireless Sensor Network (WSN) and a centralized control system. The performance evaluation of the system is accomplished through...
Monitoring and warning the expressway exit incidents is an effective way to prevent expressway accidents. This paper deals with illegal changing lanes and illegal parking behavior as the major incidents that should be monitored. In this paper, we introduce a system that aims to reduce the chance of traffic delay and traffic conflict and has put it into practice to test its effectiveness. According...
The highway is the inevitable outcome of the social and economic development. In recent years, with the rapid development of our economy, the growth of highway is becoming faster and faster. But the followed is a series of highway management issues. In view of the issues of poor vehicle control, the traditional parking charge as well as traffic jam brought by this, road toll in confusion, low level...
The application of GPS probes in traffic management is growing rapidly as the required data collection infrastructure is increasingly in place in urban areas with significant number of mobile sensors moving around covering expansive areas of the road network. The paper presents the development of a laboratory designed to explore GPS and other emerging traffic and traffic-related data for traffic monitoring...
Real time situational awareness has the potential to improve the response and management of intelligent transportation system (ITS) components in critical situations. In the event of sudden or potentially dangerous situations, such as hazardous material spills or reckless driving, every second counts to reduce the overall impact of the event. Currently, assessing surface deterioration and identifying...
Bus Rapid Transit (BRT) system is a new type and high efficient bus operator system, whose transportation capacity is close to the rail transportation, and has rapid construction speed, also can retrench the investigation. This paper introduced the intelligent control strategy which is basically realized by the Dispatching Control Center located in the Central Station. With the help of GPS system,...
The occurrence of accidents on the freeway/highway has a significant impact on normal traffic manipulations and the reasons that cause accidents are admitted primarily due to the introduction of traffic incidents. Hence, automatic traffic monitoring system gradually attracts the attention of researchers in the field of intelligent transportation system. In this paper, a vision-based approach for automatic...
Due to the strong interrelations between traffic situations at different locations of a road network the traffic control actions applied for solving a local traffic problem can create another traffic congestion at a different location in the network. This can result the average travel time on the network level, even after the application of the control actions, to be the same or worse. Therefore,...
In this paper, we have made a comprehensive study about the key technologies including applying wireless sensor networks to the traffic monitoring network, its traffic flow forecast based on gray forecasting model and traffic congestion control. According to the features that wireless sensor networks have no space constraints, flexible distribution, mobile convenience and quick reaction, we present...
According to the system requirements, vehicle detection system based on double induction loops has been designed. Control unit of traffic detection system designed with the core of LPC2138 has been described in detail. And the function of each hardware module has been analyzed. For bad experiment environment and various interference factors, anti-interference measures have been considered and introduced...
This paper presents the demonstration of a bus priority measure (IBL) in Lisbon. The traffic management in Lisbon is first introduced. Then the IBL technique and its operation at the chosen testing area are described. Finally some analysis on the field data about the obtained bus priority and the influences on the general traffic flow are also given.
