Internet of Things (IoT) is a world-wide network connecting all the smart objects together. It is the way in which all things are enabled to talk with each other. Whenever those smart things being connected over internet are restricted to only vehicles, then it is called as Internet of Vehicles (IoV). With continuously increasing urban population and rapidly expanding cities, vehicle ownership has...
In response to increase of mobile data traffic, telecom operators usually employ “enforced handover” policy to direct data traffic to WiFi AP (Access Point). Once their user clients enter into WiFi AP coverage, they will be handed over to WiFi AP from BS in order to offload mobile data traffic. However, if there are too many BS user clients enter into WiFi AP coverage, it may lead to excessive handover...
Railway companies need to achieve higher capacities on existing infrastructures such as high density suburban mainlines. Communication based train control (CBTC) systems have been widely deployed on dedicated subway lines. However, deployment on shared rail infrastructure, where CBTC and non-CBTC trains run, leads to a mixed positioning and controlling system with different precision levels and restrictions...
In this paper a road traffic monitoring system based on a 24 GHz radar sensor is considered. This radar sensor detects and tracks all moving and stationary objects in the local environment. The object tracking procedure used in the radar sensor can be improved if any road map information about the local environment of the sensor is available to the traffic monitoring system. This step is especially...
Traffic management has become more complicated because increasing road networks and vehicles day by day due to population increasing. Monitoring and tracking of movable vehicles is one of the most comprehensive issues. Decision support system for traffic management is the key points of intelligent transportation system. In this paper we propose the decision support system for handling traffic by using...
Design and development of telematics transport systems represents a new approach to solving transportation problems. Telematics offers large opportunities to strengthen the positive features of transport (availability, mobility), while minimizing its negative impacts (e.g. environmental pollution, energy consumption, congestion, accidents, infrastructure construction costs) without any additional...
Because security attacks in IP networks are becoming ever more difficult to detect, we must develop better detection systems to protect network users. One possible method which could be used is forecasting network behaviour. In this paper, we study the Holt-Winters forecasting algorithm in aberrant behaviour detection. We have built a test platform which collects real IP network traffic and calculates...
In 3G mobile communication system, mobile broadband data services create great opportunities on revenue growth for network carriers. In the mean time, the dramatically increased subscribers make the access and core network more and more over-loaded everyday. Unfortunately, majority of wireless bandwidth is consumed by non revenue driven application traffic such as the P2P downloading, illegal VoIP...
Because of the alignment, slope, road conditions and other factors, the incident rate in Mountain highway was significantly higher than other roads. Traditional Events Early Warning Systems, usually used a "multi-bank" means in the structure of the system, was difficult to apply to the complex mountain highway system. Firstly, this paper established mountain road event early warning systems'...
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...
The rapid introduction of new mobile data services presents many challenges to wireless service providers. Unlike voice services, whose traffic characteristics are well understood, new data services are far more volatile and their demand on network resources is harder to predict. Data volumes are exploding and impacting not only the ability of the network to support such traffic but are also driving...
The increasing IP based service such as IP video, IP voice as well as high speed internet, leads to an evolution of current transport network to packet transport network (PTN). Nowadays, using the Generic Framing Procedure, the main transport network is based on Muti-Service Transport Plat (MSTP), which foreshows that there would be a time for the combination of the two networks. By introducing the...
The expressway facilities management system is becoming crucial for successful traffic management with the spreading of expressway construction in China. In this paper, the current expressway facilities management systems are analyzed. Due to lack of the spatiotemporal data management capability of these systems, a bi-temporal spatial data model is proposed, which combines the temporal relational...
Emerging trends in software development has been changed due to the huge amount of data, growth of internet, mobile, dynamic and smart applications. Most of such applications consist of small, intelligent, flexible and distributed components known as agents. Number of agent methodologies has been presented but few of these are evaluated and verified. Due to the invention of agent technology, the way...
Vessel dynamics video monitoring system is one of the most significant components in port safety and traffic management. This paper intends to discuss the key points in the design of the system: firstly, the data concerning vessel dynamics position are acquired via AIS; then intelligent video tracking system automatically drives intelligent spherical cameras to monitor vessels in port. Also system...
Information integration is a key for further growth of efficiency in management decisions for the railway domain. In the context of the EU project InteGRail (funded in the 6th Framework Programme) an integration approach leveraged by ontologies known from the semantic Web and logic-based reasoning mechanisms has been successfully demonstrated. To this effect existing heterogeneous monitoring data...
Wireless sensor network (WSN) & radio frequency identification (RFID) integrated technology (wireless sensing identification, WSID) is an inevitable trend in WSN and RFID fields in the future, Especially the RFID based on automated identification helps the objects identification in traffic management to become more simple and exact. In this paper, RFID is integrated into highway traffic monitoring...
This paper proposes a new method for real-time distributed image acquisition through wireless networks of traffic monitoring cameras. The goal is to provide comprehensive image acquisition in the presence of dynamic disturbances, which obstruct the field of view (FOV) of the cameras. The paper presents a collaborative online algorithm, which (upon FOV loss) identifies an optimized set of cameras that...
This paper describes an approach to road network monitoring. The approach has the following components: a multi-agent hierarchical monitoring system in which the agents are network elements, such as crossings, road segments and routes, software engineering techniques to handle legacy sensors and to homogenize their heterogeneous data streams, distributed Kalman filtering to reduce sensor noise and...
Traffic management in an urban area is highly facilitated by the knowledge of the traffic conditions in every street or highway involved in the vehicular mobility system. Aim of the paper is to propose a neuro-fuzzy approach able to compute the main parameters of a traffic system, i. e., car density, velocity and flow, by using the images collected by the web-cams located at the crossroads of the...
