This paper focuses on the break-taking behaviour pattern of long-distance freight vehicles, providing a new perspective on the study of behaviour patterns and simultaneously providing a reference for transport management departments and related enterprises. Based on Global Positioning System (GPS) trajectory data, we select stopping points as break-taking sites of long-distance freight vehicles...

GPS is the positioning technology of choice for a wide range of land-based applications. Since the mid-1990s GPS products have been on offer for the 'agricultural market'. GPS on its own does not appear to contribute much to improving agricultural productivity. Hence 'precision agriculture' has generally referred to the intergation of GPS within a total system that, for example, uses spatial in...

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...

A position-velocity (PV) model and a multi-sensor system, consisted of a consumer application GPS, a MEMS gyro, two encoders, and a turning angle sensor, was constructed for the positioning system. The two encoders augmented the positioning accuracy greatly that the fluctuation of vehicle position was greatly smoothed comparing with a GPS-only system. The minimal fluctuation was falling from 2....

Mobile robots must have some effective method for determining their position in the working environment in order to operate appropriately. In this paper, precise outdoor positioning of a vehicle is achieved by continuously fusing odometry with wide-area Differential Global Positioning System (DGPS) data through a Kalman filter. The propagation and reduction of spatial uncertainty is computed to...

U.S. Army RDECOM-TARDEC, in collaboration with Oakland University and JADI Inc., is currently conducting novel research devoted to obtain fine-grain (centimeter accuracy) indoor positioning for unmanned ground vehicle (UGV) navigation applications using Ultra-Wideband (UWB) technologies. This paper will present recent results from advanced closed-form solutions and analyses for positioning erro...

In this paper, an integrated inter-vehicles wireless communications and positioning system supporting alternate positioning techniques is proposed to meet the requirements of safety applications of Cooperative Intelligent Transportation Systems (C-ITS). Recent advances have repeatedly demonstrated that road safety problems can be to a large extent addressed via a range of technologies including...

Current fast and reliable Internet services provide many advantages for worldwide GNSS users. Development of techniques using the Internet for streaming RTK/DGPS corrections allows mobile users to achieve high-accuracy positioning over both short and long baselines. Applications like GNSS Internet Radio are used for distributing raw GPS data and real-time corrections of GPS observations via RTC...

With the evolution of communication networks, Internet Vehicles (IOV) continues to accelerate safe and rapid development autonomous vehicles. Vehicle-to-Pedestrian (V2P) is a key technology in vehicles potential solution realize collaborative intelligence between pedestrians. However, existing V2P early warning system does not consider uncertainty pedestrian trajectory, determination collision ...
