This paper deals with the implementation of an intelligent bus monitoring system based on current challenges and problems. Home network based applications are very diverse and the remote monitoring and control areas have been studied. Recently, Zig-Bee has become one of the most promising technologies for home networks and integrated sensing technologies such as global positioning system (GPS),...

The pseudolite system is a good alternative for indoor positioning systems due to its large coverage area and accurate positioning solution. However, for common Global Positioning System (GPS) receivers, the pseudolite system requires some modifications of the user terminals. To solve the problem, this paper proposes a new pseudolite-based indoor positioning system architecture. The main idea i...

One of the most difficult and expensive tasks in making noise pollution maps is the collection and processing of the data needed to create acoustic models. In the case of road traffic noise maps, obtaining speed data for light and heavy vehicles a problem that has usually been avoided by using a road’s speed limit or by making assumptions based on experience from similar road types. Here global...

An economically eficient and eflective transportation system is one of the essential components for the economic and sociai weil-being of agribu~”ness~rms that provi& agricultural andfoodproducls to consumers and end-users in the state. One possible methdfor improving that system is the use of tnteliigent Transportation Systems (ITSS). ITSS are systems that encompass several technologies, inclu...

This report describes a simulation model developed to evaluate the impact of using Intelligent Transportation Systems (ITS), such as Global Positioning Systems (GPS) for bus tracking, on controlling buses in wide-area transit networks. Control strategies with ITS will be compared against those without ITS (i.e., they do not rely on communication or tracking). The model is developed using a gene...

This paper discusses the recent Geo-ICT developments, such as information system modelling standards, database technology, global positioning systems, Internet development, wireless communication and acceptance of geometry standards within general ICT tools and its uses on cadastral systems. Efficient design, development, testing and maintenance of cadastral systems allow the introduction of su...

BACKGROUND Although sources of positional error in geographic locations (e.g. geocoding error) used for describing and modeling spatial patterns are widely acknowledged, research on how such error impacts the statistical results has been limited. In this paper we explore techniques for quantifying the perturbability of spatial weights to different specifications of positional error. RESULTS W...

In a network of thousands of nodes, usually densely deployed, it is unlikely that the designer will determine the position of each node. To process sensor data, however, it is necessary to know where the data come from. Equipping every node with a global positioning system (GPS) is currently a costly (in volume, money, and power consumption) solution. Instead, we can estimate node positions rel...

Several ways to estimate the position of a WirelessSensor-Network (WSN) node have been discussed in the past years. Unlike in outdoor solutions where the Global Positioning System (GPS) could be used in most applications, a general solution for indoor usage has not been found. The few existing indoor solutions on the market are highly specialized and rely on infrastructure or on very expensive ...
