Real-time path planning is one of emergent approaches which efficiently reduce traffic jam in urban scenarios. Designing an efficient path planning strategy to achieve optimal vehicle-traffic flow control still remains a challenging problem, especially when we take human's uncooperative and uncoordinated selfish behaviors into consideration. In this paper, we first introduce an intelligent transportation...
In this paper we present SmartRoad, a crowd-sourced sensing system that detects and identifies traffic regulators, traffic lights and stop signs in particular. As an alternative to expensive road surveys, SmartRoad works on participatory sensing data collected from GPS sensors from in-vehicle smartphones. The resulting traffic regulator information can be used for many assisted-driving or navigation...
The threat of terrorism is a constant reminder of the significance of developing effective strategies to safeguard the population. This is particularly important in large, densely populated areas, which can often be the primary targets of a terrorist attack. In such a situation, the implementation of a depopulation plan becomes very challenging to manage. This paper explores one possible method of...
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...
In this paper, we present a traffic information service platform to alleviate difficulties of current urban traffic systems. For problems including difficulty of parking, traffic congestion and passengers missing taxies may be caused by lacking of real time information; the platform can provide useful information based on devices such as vehicle passing sensors, mobile communication modems and smart...
Intelligent Transportation Systems (ITS) and their applications are attracting significant attention in research and industry. ITS makes use of various sensing and communication technologies to assist transportation authorities and vehicles drivers in making informative decisions and provide leisure and safe driving experience. Data collection and dispersion are of utmost importance for the proper...
There is a significant push towards greater vehicular autonomy on roads to increase convenience and improve overall driver experience. To enable this autonomy, it is imperative that cyber-physical infrastructure be deployed to enable efficient control and communication. An essential component of such road instrumentation is intersection management. This paper develops an intersection management platform...
This work-in-progress article presents the research objectives of the (CIA)2-ITS workgroup of the Brazilian project consortium called (CIA)2. The workgroup is developing an architecture and protocols to integrate the heterogeneous networks and devices that compose a city-wide (or even nation-wide) Intelligent Transportation System (ITS). The ITS architecture will support networks of wireless sensors...
We take the paradigm of cloud computing developed in the cyber-world and put it into the physical world to create a cyber-physical computing cloud. A server in this cloud moves in space making it a vehicle with physical constraints. Such vehicles also have sensors and actuators elevating mobile sensor networks from a deployment to a service. Possible hosts include cars, planes, people with smartphones,...
Road congestion is a common problem all over the world. In many developed countries, automated congestion detection techniques have been deployed, that are used in road travel assisting applications. But these techniques are mostly inapplicable in many developing regions due to high cost and their assumptions of orderly traffic. Efforts in developing regions have been few. In this paper, we present...
Modern cars are equipped with a variety of sensors, advanced driver assistance systems and user interfaces nowadays. To benefit from these systems and to optimally support the driver in his monitoring and decision making process, efficient human-machine interfaces play an important part. This paper describes the second release of iDriver, an iPad software solution which was developed to navigate and...
This paper presents vehicle control system for automatic valet parking with infrastructure sensors. First, we describe the automatic valet parking service system. In the service, vehicle moves autonomously based on sensing data generated by infrastructure sensors. Second, we implement vehicle control system for automatic valet parking. We design hardware and software components focusing on minimizing...
Electronic toll collection (ETC) with combined information and communication technology has become a major concern in the intelligent transportation systems. In this paper, an efficient design of ETC system is proposed, which incorporates automatic vehicle classification, identification, and violation enforcement. In the proposed design, to enhance the level of security in data communication, a two...
One opportunity to manage the increase of freight transportation and to optimize utilization of motorway capacities is the concept of truck platoons. With the aid of Advanced Driver Assistance Systems, trucks are electronically coupled keeping very short gaps (approx. 10 meters) to form truck platoons on motorways. This contributes to optimization of traffic flow and reduction of fuel consumption...
In this paper we apply classification to learn geographic regions using Location Based Services (LBS) in Next Generation Networks (NGN). We assume that the information in Local Network (cellular network) can be freely exchanged with Global IP Network (NGN) and the information can be gathered in a database. Location Based Services (LBS) in the IP Multimedia Subsystem (IMS) also provide location information...
The driver assistance system is more and more widely used with the development of automobile industry. The driver assistance system based on pervasive computing integrates the function of computing, communicating and sensing, which can assure the driving safety and prejudging the traffic emergency by sharing the information among vehicles of the same district. The structure and working principle of...
Autonomous Underwater Vehicle (AUV) technology has matured over the past few decades but commercial AUVs today remain complex, proprietary and expensive. Modularity in AUVs at a software, electronics and mechanical level allows users to configure AUVs for specific missions by only including the required components. With multiple base AUVs, users may easily configure heterogeneous teams of AUVs for...
