Abstract

Purpose — The principal hypothesis of this program of research is that people's choices of which resources to own are a function of expected travel needs.

Methodology/approach — This chapter reports recent research using a stated-choice survey design that is innovative in two respects. First, respondents are asked to consider two types of choice having different time horizons but which are thought to be linked in a strategic-tactical structure. The two types of choices are (a) purchasing ‘mobility resources’, which include commitments such as car ownership and subscription to carsharing services and (b) choosing a mode of transport for a particular instance of travel. The second methodological innovation is that respondents indicate their choices in the context of giving advice to a demographically similar ‘avatar’.

The development of a technique for ‘empirically constrained’ efficient design is discussed, as is its application to this survey. This objective is to provide survey designs with a high degree of statistical efficiency whilst maintaining plausibility in the combination of attribute levels. Field data from an empirical application (n = 72) was collected and analysed.

Findings — The proposed method for efficient design proved successful. The main substantive findings from the empirical application are presented, along with detailed results relating to how different demographic classes of respondents engaged with the instrument. For instance, living with one's partner and living with no children at home were associated with high scores on a scale of similarity between the experimental choice context and one's real-world mobility choices.

Research limitations/implications — The proposed techniques appear promising, though the empirical results must be viewed as indicative only due to the size and coverage of the field data sample.

Abstract

Purpose — The Department for Transport's 2011 GPS National Travel Survey (NTS) pilot study investigated whether personal GPS devices and automated data processing could be used in place of the 7-day paper diary. Using GPS technology could reduce the relatively high burden that the diary places upon respondents, reduce costs and improve data quality.

Design/methodology/approach — Data was collected from c.900 respondents. Practical changes were made to the existing methodology where necessary, including the collection of information to support data processing. Processing was undertaken using the University of Eindhoven's Trace Annotator. Results from the GPS pilot were then compared to those from the main NTS diaries for the same period.

Findings — There were no insurmountable problems using GPS devices to collect data; however, the processed GPS data did not resemble the diary outputs, making GPS unsuitable for the NTS. The GPS data produced fewer and longer trips than the diary data. The purpose of a quarter of the GPS trips was unclear, and a disproportionate share started and ended at home.

Research limitations — Further work to manually inspect trips identified via validation as unfeasible and subsequently refine the processing algorithms would have been desirable had time permitted. GPS data processing may have been hindered by missing GPS data, particularly in the case of rail travel.

Originality/value — This research used an accelerometer-equipped GPS device to better predict the method of travel. It also combined addresses that respondents reported having visited during the travel week with GIS data to code the purpose of trips without using a post-processing prompted-recall survey.

Abstract

Purpose – Departure time choice not only depends on the desire to carry out activities at certain times and places; it is a complex decision making process influenced by travel conditions, congestion levels, activity schedules, and external trip factors. To estimate departure time choice models capturing the factors influencing it in appropriate form, a complex data collection procedure allowing to obtain detailed input data from different sources and at different time periods is required.

The main aim of this chapter is to describe and discuss the survey methodology we used in a time-of-day choice project, involving the collection of revealed preference (RP) and stated preference (SP) data to estimate hybrid discrete departure time choice models incorporating latent variables. Preliminary model results are also presented as an example.

Methodology/approach – Data was obtained from 405 workers at different private and public institutions located in the centre of Santiago, Chile. The survey process had three different stages and used various collection methods (e-mail, web-page, and personal interviews at the workplace) in order to satisfy efficiency, reliability and cost criteria.

The RP component survey design was based on the last origin-destination survey implemented in Santiago (i.e. a travel diary filled under an activity recall framework). Relevant level-of-service measures at different time periods were obtained from GPS data measured from instrumented vehicles in the public and private transport networks. A SP-off-RP optimal design considering dependence among attribute levels was also developed. Finally, several 1–7 Likert scale questions were included to incorporate the latent variables.

Findings – The survey methodology described in this chapter represents a successful experience in terms of collecting high quality data, from different sources, with the aim of estimating appropriate time-of-day choice models. The data collection process was carried out in different stages, by means of web pages, email, and personal interviews. The data was further enriched with level-of-service attributes measured at different times of the day with unusual precision. Preliminary results reported in this chapter show that data obtained through this methodology are appropriate to model time-of-day choices.

Originality/value of chapter – The novelty of the survey methodology described in this chapter is the collection of data of a different nature for time-of-day choice modelling through the integration of different collection techniques.

Acquisition of very precise information about preferred departure/arrival times, level of service at different times of the day, detailed information about flexibility in schedules, employment information and attitudes towards departure times, should allow practitioners to estimate hybrid time-of-day choice models incorporating latent variables.

Abstract

Purpose

Expanding on the findings of the SOPIFF research project, this paper aims to identify eight futures schools of thought, which are analyzed and critiqued through an integral framework. As “Part II” of a previous publication, it seeks to focus on the lower (plural) quadrants.

Design/methodology/approach

The paper adapts Ken Wilber's integral theory to clarify various philosophical orientations to the future. It also adapts Fredrich Polak's approach to futures as a matter of “social critique and reconstruction”; however, the approach is global, civilizational, and integral, so it proposes civilizational critique and integral reconstruction as a method for evaluating futures schools of thought.

Findings

The IF framework is found to be a valuable theoretical and analytical tool for clarifying images of the future; it shows lines of development within each quadrant and interactions between quadrants, illustrating the effectiveness of the four‐quadrant approach.

Research limitations/implications

It further illuminates the “global problematique” expressed in the SOPIFF project and proposes the IF framework as a way to interpret those research findings.

Practical implications

This approach to futures/foresight studies broadens the range and offers more depth to conceptions of the future, so it should help to develop/improve futures methodologies/practices in general.

Social implications

Civilizational critique and integral reconstruction of images of the future imply unprecedented social change.

Originality/value

The paper should help futurists to see and interpret the “bigger picture” of civilizational futures through revealing the “crack” of the modern image of the future, how it relates to the current world crisis, and what is needed to heal the crack, so a new vision of a preferred future can emerge.

Abstract

Purpose

This paper aims to expand on the findings of the SOPIFF project by identifying eight futures schools of thought, and then analyze and critique these through the integral futures (IF) framework. This paper, Part I, also aims to focus on the upper quadrants of the IF framework.

Design/methodology/approach

The paper adapts Wilber's integral theory to clarify various philosophical orientations towards the future. It also adapts Polak's approach to futures as a matter of “social critique and reconstruction”; however, here the approach is global, civilizational, and integral, so it proposes civilizational critique and integral reconstruction as a method for evaluating futures schools of thought.

Findings

The IF framework has proved to be a valuable theoretical and analytical tool since it clarifies not only orientations to the future but also demonstrates the dynamic lines of development and interactions throughout all four quadrants, illustrating how the four‐quadrant approach is an effective framework for understanding the crisis of civilization and the response needed at this time in history to bring about a preferred future.

Research implications/limitations

The paper draws and expands upon the findings of the SOPIFF project as a way to better understand the “global problematique.” Thus, this paper suggests some implications of that research and proposes the integral futures framework as a way to interpret research findings. Future research should attempt to develop and apply the IF framework similarly in order to realize a sustainable, integrally‐informed image of the future of human civilization.

Practical implications

An integrally‐informed approach to futures and foresight studies should help develop and improve futures methodology/practices in general. The IF framework helps to understand philosophical orientations underlying practices and applications.

Originality/value

This application of the IF framework to various mainstream futures schools of thought is original. It should help futurists to see and interpret the bigger picture regarding images of the future in a civilizational context by revealing the “crack” in the modern image of the future, how it relates to the current world crisis, and what is needed to heal the crack so that a new, more integrally‐informed, sustainable image of the future can emerge.
