Use of Navigation Systems and Consequences for Travel Behavior

Abstract: On the European market, navigation systems gain growing importance for the support of travelers on both their everyday and special travels. So they have the possibility to contribute to the optimization of transport. This assumes that navigation systems are not just a part of the (standard) equipment of cars or households, but have to be used frequently. Therefore a broad acceptance of navigation systems has to exist. Following a scheme of acceptance, which understands acceptance as a dynamic process, the availability and use of navigation systems as well as the influence on travel behavior and travelers’ references while using a navigation system are analyzed in this article. The report on a study made by DLR-Institute of Transport Research gives an insight about acceptance and current use of navigation systems. It deals with a nationwide online survey among 1.311 navigation system users, addressing particularly the questions in which situations the navigation system is utilized, by which frequency and how people use to react to the information they get. It will be pointed out that the acceptance of navigation devices goes beyond the decision to buy them. It is evident that navigation devices are used and followed to a high extent. This is particularly true for less routine purposes, such as vacation and business trips. Altogether the use of navigation system has primarily influence on travel behavior in terms of choice and scheduling of certain routes.

Traffic information management server, navigation terminal and method

Abstract: PROBLEM TO BE SOLVED: To provide a navigation system for improving accuracy of an electronic map of a navigation terminal and reducing costs of navigation information service. SOLUTION: This traffic information management server extracts a position ID on a course route, traffic information and reliability information corresponding to the position ID from a traffic information database, generates a traffic message, and transmits the traffic message to the navigation terminal based on a request message from the navigation terminal. Furthermore, the reliability information corresponding to the position ID in the database is updated based on feedback information from the navigation terminal. COPYRIGHT: (C)2009,JPO&INPIT

Indoor Navigation Validation Framework for Visually Impaired Users

Abstract: In this paper, we introduce the first validation framework of an indoor navigation system for blind and visually impaired (BVI) users, which is a significant step toward the development of cost effective indoor way-finding solutions for BVI users. The BVI users require detailed landmark-based navigation instructions that will help them arrive at the chosen destination independently. These users will interact with the navigation instructions on a smartphone using an accessible user interface. The validation framework includes the following three main components: 1) virtual reality-based simulation that simulates a BVI user traversing and interacting with the physical environment, developed using Unity game engine; 2) generation of action codes that emulate the avatar movement in the virtual environment, developed using a natural language processing parser of the navigation instructions; and 3) accessible user interface, which enables the user to access the navigation instructions, developed using Sikuli script library. We introduce a case study that illustrates the use of the validation tool using PERCEPT system. It is our strong belief that the validation framework we provide in this paper will encourage other developers to invent indoor navigation systems for BVI users. In addition, we would like to mention that this tool is the first step of validating an indoor navigation system and should be followed by trials with human subjects.

Methods and systems of network-based indoor location estimation using multiple Wi-Fi access points

Abstract: A computer-implemented method and system for determining navigation/positional data, implemented in a computing system programmed to perform the method. The method includes receiving a plurality of signal strength measurements and user ID data from a hand-held user device, determining user navigation/position data using the plurality of signal strength measurements from the hand-held user device, and transferring the user navigation/position data to the hand-held user device in response to a request signal associated with the user ID data. The user navigation/position data can include 2-D position, 3-D position, relative position, heading, orientation, speed, bearing, and the like. Benefits of this method and system include user hardware independence, reduced computational load on user hardware, and network-level tracking of aggregated traffic patterns.

Game navigation interface for electronic content

Abstract: A game navigation interface for electronic content is described. A computer-implement system may comprise a content delivery platform operative to manage multimedia content. The computer-implemented system may further comprise a game navigation application operative to manage a game for the content delivery platform. The game navigation application may comprise a monitoring component operative to monitor navigation commands for navigating multimedia content provided by the content delivery platform, and output a game trigger signal based on the navigation commands. The game navigation application may further comprise a game navigation component operative to receive the game trigger signal, and select a game arranged to assist a user in navigating the multimedia content in response to the game trigger signal. Other embodiments are described and claimed.
