Purpose — In order to analyse applicability, comparability and limitations of GPS technology in travel surveys, different mobility survey techniques were tested in an Austrian pilot study.

Methodology/approach — Four groups of voluntary respondents recorded their travel behaviour over a time period of three consecutive days. The groups were assigned to three different and combined methods of data collection: Paper–pencil trip diaries, passive GPS tracking, active GPS tracking and prompted recall interviews.

Findings — The resulting mobility parameters show that self-reported paper– pencil surveys yield accurate sociodemographic information on the respondents as well as trip purposes and modes of transportation, although too few trips are reported. Passive GPS-based methods minimize the strain for respondents. Methods that combine GPS-based data collection and questionnaire provide the most reliable mobility data at the moment.

Research limitations/implications — Due to funding restrictions the sample sizes had to be relatively small (235 participants). Further development in research methodology will increase the effectiveness of automated data analysis, for example more accurate detection of activities and transport modes. The usefulness of GPS-based data collection in a large-scale surveys is planned to be tested in the next Austrian national travel survey.

Originality/value of paper — The pilot study allows a detailed comparison of traditional and GPS-based travel survey methods for the first time, due to data collection combined with prompted recalls.

The ‘people versus technology’ debate is ongoing; and as the social care system becomes ever more cash‐strapped and the shortage of appropriately skilled people continues, so will this debate. One of the emerging uses of technology is the application of satellite technology to monitor the movements of people with dementia, but just how effective is the technology to not only improve the life of the client, but his or her carer too? Here, Rupert McShane and Lindsey Skelt tell of the trials they conducted and what they believe that the next steps should be.

The purpose of this study is to build the Android-based applications for parent to supervise, control and restrict the children’s usage of the smartphone and tablet.

The method used is the method of analysis, i.e. collection of necessary data. The data are collected from journals, articles, books, questionnaires and the similar application analysis.

The GPS tracking feature of the parental control application facilitates searching the children’s location by indicating the location where they used their Android device. The history feature of the parental control facilitates finding out what application was accessed by their children through their Android-based application, and the time limit feature of the parental control application facilitates restriction on time that the children spend on their Android-based gadgets, so that they will not be addicted to the gadget.

The parental control application for the Android platform provides users or parents a means for managing the young generation’s usage of an Android-based mobile device.

The paper aims to comprehensively use the knowledge of tourist spatial behaviour to improve World Heritage Site (WHS) management. Efficient heritage management can be achieved if critical aspects such as tourist spatial activities were better and comprehensively understood, primarily at the micro-level. Inaccurate information on these essential aspects will potentially cause problems in managing a WHS and compromises its Outstanding Universal Value. This study aims to extend the knowledge of tourist spatial behaviour by including the non-spatial and spatial characteristics of the tourists to better manage a WHS.

This study uses a trip diary and a GPS tracking app with 384 free independent tourists as the study respondents. Melaka WHS was chosen as the study area. The data were complemented by an aggregative analysis method to extract different discrete patterns based on individual itineraries.

This paper indicates a noticeable relationship between individuals’ non-spatial and spatial characteristics. It suggests that integrating these two characteristics can provide more comprehensive knowledge of tourist behaviour.

This paper provides a different perspective to improving WHS management by determining the operative tools to develop an effective visitor management plan.

This paper is aimed at telecare service providers and individuals who are aiming to manage the risks to a vulnerable person, who may be prone to becoming lost away from their own home. It aims to help them identify the issues that may be relevant in specifying the most appropriate GPS location device from the many models now on the market.

The reported study is based on a comparison of six commercial devices with three different form characteristics. Technical measures of performance were undertaken in an objective manner for each device. These were considered along with the subjective views of a panel of stake‐holders looking at issues such as usability, wearability and aesthetics in determining value for money and the optimum device for individual users.

The work concluded that battery management was of vital importance, and that the use of geo‐fencing for alarm purposes was often limited by the minimum practical size of the fence and by the way that it could be established.

It is recommended that service providers employ a range of GPS devices within their inventories, so that they are not limited to one or two different devices when prescribing telecare services to people who are at risk of wandering, especially at night. The variation in cost between the most expensive and the cheapest can be justified in terms of service support and other options. These devices are most likely to be of benefit when used within a telecare service that can offer 24‐hour monitoring and links to a dedicated emergency response team.

Transport policy is constrained by the dilemma of the positive impacts of lowering the generalised costs of travel and their today non-ignorable negative externalities. This chapter details this dilemma and discusses current policy ideas to manage and overcome it against the impacts of the COVID-19 pandemic on travel habits and work behaviour. The impacts are presented for Switzerland for which a large-scale GPS tracking survey spanning the autumn 2019 to winter 2021 period is available. The chapter concludes by highlighting the dilemma of transport policy by discussing a number of potential solutions for the future.

While digital technologies have led to many important social and cultural advances worldwide, they also facilitate the perpetration of violence, abuse and harassment, known as technology-facilitated violence and abuse (TFVA). TFVA includes a spectrum of behaviors perpetrated online, offline, and through a range of technologies, including artificial intelligence, livestreaming, GPS tracking, and social media. This chapter provides an overview of TFVA, including a brief snapshot of existing quantitative and qualitative research relating to various forms of TFVA. It then discusses the aims and contributions of this book as a whole, before outlining five overarching themes arising from the contributions. The chapter concludes by mapping out the structure of the book.

The purpose of this paper is to improve the tracking performance of the carrier phase lock loop (PLL) in the strapdown inertial navigation system/global positioning system (SINS/GPS) integrated system with an innovative scheme of ultra‐tight integration.

First, providing the Doppler frequency for PLL using SINS velocity could enlarge the loop equivalent bandwidth and reduce the dynamic effect on the carrier loop. Meanwhile, lowering the filter bandwidth could increase the immunity to noise. Second, the relationships between the PLL and SINS errors have been analyzed, and then the PLL error model is established to eliminate the correlation between the pseudo‐range‐rate error and SINS velocity error. Third, the carrier frequency is regulated to improve the tracking accuracy, according to the error estimations of Kalman filter.

The innovative ultra‐tightly integrated system could not only enhance the anti‐jamming capability and the dynamic tracking performance of the tracking loops, but also improve the pseudo‐range‐rate measurements accuracy for the integrated filter.

This paper provides further study on the method of enhancing the carrier‐tracking performance and improving the integration mode in the ultra‐tightly integrated system based on the software‐defined GPS receiver.

Surveys of the public have been conducted to document and explain evacuation behaviour in a wide range of threatening events during the past half-century. Many of the behaviours are directly applicable to transportation modelling and management: whether people evacuate, when they depart, where they go, the routes they employ and the number of vehicles they use. Data have usually been collected by telephone interview or mailed questionnaires. Traditional survey methods should be supplemented by Internet surveys, traffic counts and GPS tracking. More real-time data collection should be employed to document a wider range of behaviours during a threat more accurately and to better understand the dynamics of evacuation decisions.
