Time use, travel behavior, and the rural-urban continuum: results from the Halifax STAR project

This paper considers variations in time-related aspects of travel behavior along the urban-rural continuum, using the four categories of inner city, suburbs, inner commuter belt (ICB), and outer commuter belt (OCB). It employs geo-coded and GPS-validated data from the STAR survey conducted in the county-sized regional municipality of Halifax, Nova Scotia. Many significant inter-zonal differences are identified, and most travel variables are characterized by progressive urban-to-rural gradients, with large differences between inner-city and outer-commuter values. A clear break between city and country is seldom evident, however. Inner-city residents make most trips, but have trips of shortest duration, and spend least time in travel. Residents of the commuter belts spend most time in travel, and have trips of longest duration. While long trips and much driving were expected in commuter zones, there are significantly fewer trips in the OCB, which we attribute to lack of need, lack of opportunities, and adjustments in discretionary behavior.     

Estimating social travel demand of senior citizens in the Netherlands

Like many other countries, the Netherlands is experiencing a sharp rise in the ageing population. As age increases, people’s mobility may decrease. However, older people have more leisure time compared to their younger (working) counterparts, and potentially spend more time on social activities. Therefore, this group can possibly increase social travel demand. However, to date, the travel demand for social activities of senior citizens has received only little attention. This paper studies trip-making for social purposes, with a special focus on the demographic ageing factors. Using social activity diary data, models are estimated to predict the number of social trips, the travel distance and mode of transport for social trips. The results indicate that the elderly of today seem to be as mobile as their younger counterparts with respect to the number of social trips. High education and involvement in clubs on average result in more social trips and full time work is found to result in fewer social trips. With regard to trip distance the results show that the average travel distance does not decrease as people get older. Full time work is found to result in longer social trips. Shorter trips were found for people in urban as well as rural areas. Trips for the purpose of visiting or joint activities tend to be longer than average. With regard to transport mode choice the results indicate that older seniors (75+) are less likely to choose the bicycle, relative to driving. No other significant age effects were found. Significant effects were found for gender, household structure, education level, car ownership, having a disability, urban density, distance and the purpose of the social activity.     

Analysis of travel behavior in Arab communities in Israel: a comparison of household surveys

This paper analyzes the main characteristics of travel behavior by the Arab minority community in Israel and discusses two issues related to household travel surveys: data collection among minorities and under-reporting of mid-day trips.Household travel surveys are generally designed and conducted for the majority population and, therefore, lack a proper accounting of minorities and miss many of their less-frequent trips. An alternative approach to conducting household surveys is presented, with the aim of improving data quality for transportation planning. The survey was designed for and conducted in three Arab towns in Israel. The main improvement of the survey involves better interaction between interviewer and interviewee, which should materialize into a relaxed environment that allows for obtaining detailed, reliable results within a reasonable amount of time.The results of the survey employing the alternative approach were compared to a sub-sample of the same towns taken from a regional survey conducted by the regional planning agency at the same time. The paper presents simple statistics on the main variables for each survey. Significant differences are found in the two data sets, mostly regarding the frequency of less frequent, non-home-based trips. A plausible explanation for these differences relates to the more detailed and improved data collected in the new survey.     

Destination product characteristics as useful predictors for repeat visiting and recommendation segmentation variables in tourism: a CHAID exhaustive analysis

The present paper constitutes a segmentation research with the use of the exhaustive chi‐squared automatic interaction detection tree analysis approach which, through the characteristics of a tourist destination, aims at the illustration of the English and German tourist groups and more specifically, (i) those who are repeat visitors of several tourist destinations and (ii) those who express a willingness to urge other people to visit geographic tourist destinations that the former have already visited. The results of the research help the tourism managers to apprehend the characteristics of the destination products that best describe the visitors. Copyright © 2008 John Wiley & Sons, Ltd.     

Gendered key events in the life course: effects on changes in travel mode choice over time

This paper studies changes in travel mode specific trip rates after life course (and accessibility) related key events from a gender perspective. It is theoretically informed by the mobility biographies approach, and by gender/travel studies. The data used is the German Mobility Panel (GMP) 1994 to 2010 in which households and their members are asked three times in three subsequent years to report the trips they made over a week. The changes reported are regressed to key events over the life course, cohort effects and period effects, while sociodemographics and spatial context attributes are controlled. A cluster–robust regression approach is used to account for the non-independent character of panel observations. Significant effects were found for some key events, including the birth of a child, entry into the labour market, and changes in spatial context, accessibility and mobility. Some effects differed distinctly between men and women, suggesting that men and women are differently affected by life course events. However, taken together the associations found, as well as their gender differences are rather limited. Hence, key events over the life course seem to be only loosely associated with travel mode specific trip rates.     

The impact of COVID-19 on airline passenger travel behavior: An exploratory analysis on the Chinese aviation market

China was the first airline market in the world to be hit hard by the COVID-19 pandemic. It has been gradually recovering as the pandemic is largely contained domestically. However, with the global pandemic spread and great uncertainty, there has been a remarkable change in airline passengers’ travel behavior. This paper collected air passenger-level data from TravelSky in the Chinese market. In addition to the analyses on aggregate passenger flow patterns, this paper explores changes in airline passenger travel behavior, such as ticket booking time, age distribution of passengers, refunds and ticket changes, and passenger arrival time at airports. This is one of the first studies to focus on micro-level changes in airline passenger travel behavior by using objective passenger-level data. The pandemic-induced psychological changes in air travelers are explored, providing useful managerial and policymaking implications for the normalization of the pandemic and the recovery of the airline market in the post-pandemic era.     

Congestion tolls and parking fees: A comparison of the potential effect on travel behavior

This paper presents a comparison of attitudes towards congestion and parking tolls and explores their effect on travel behavior. The findings indicate that drivers are sensitive mainly to congestion tolls and are willing to change their travel habits to avoid these tolls. The major effect of a congestion toll is the shifting of the time of the journey. High levels of demand elasticity (−1.8 for congestion tolls and −1.2 for parking fees) were found. The readiness to pay parking fees is greater; thus, the effectiveness of congestion tolls in reducing demand is higher during the times the tolls apply.     

Distance traveled in three Canadian cities: Spatial analysis from the perspective of vulnerable population segments

The objective of this paper is to investigate the factors that influence distance traveled by individuals in Canadian urban areas, with a particular focus on three population segments thought to face the risk of mobility challenges: the elderly, low-income people, and members of single-parent households. Data obtained for three large urban centers - Hamilton, Toronto, and Montreal - are analyzed using spatial expansion models, a technique used to obtain spatially-varying coefficients that help to tease out contextual person-location variations in travel behavior. Detailed geographical results help to enhance our understanding of the spatiality of travel behavior of the population segments of interest. Substantively, the results provide evidence of significant interactions between location, various demographic factors, and mobility tools. More specifically, the results evince patterns of mobility that are significantly different from the mainstream population, particularly in suburban settings, in ways that are indicative of mobility challenges.     

Income and distance elasticities of values of travel time savings: New Swiss results

This paper presents the findings of a study looking into the valuation of travel time savings (VTTS) in Switzerland, across modes as well as across purpose groups. The study makes several departures from the usual practice in VTTS studies, with the main one being a direct representation of the income and distance elasticity of the VTTS measures. Here, important gains in model performance and significantly different results are obtained through this approach. Additionally, the analysis shows that the estimation of robust coefficients for congested car travel time is hampered by the low share of congested time in the overall travel time, and the use of an additional rate-of-congestion coefficient, in addition to a generic car travel time coefficient, is preferable. Finally, the analysis demonstrates that the population mean of the indicators calculated is quite different from the sample means and presents methods to calculate those, along with the associated variances. These variances are of great interest as they allow the generation of confidence intervals, which can be extremely useful in cost-benefit analyses.     

Destination choice and the identity of places: A disaggregated analysis for different types of visitor population environment in the Netherlands

Individual behaviour relates to the ecological structure or identity of places. In this study, we investigated the relationship between the space–time ecologies of different types of visitor population environment in the Netherlands and destination choice. Multinomial logistic regression modelling for car users was applied to determine the relative importance of various personal and household attributes on choosing for a particular purpose a particular type of visitor population environment during a particular time period of the day. The attributes with the strongest link to the space–time ecologies of destination environments proved to be age, educational level, car ownership, and household income and type.     

Using the land-use planning process to secure travel plans: an assessment of progress in England to date

A travel plan is a package of measures implemented by an organisation to encourage people who travel to/from that organisation to do so by means other than driving alone by private car. This paper advances two principal arguments: firstly, that the planning system and maximum parking standards as part of it are the main factors leading to travel plan development in England today; and, secondly, that the difficulties of using the planning system in this way means that there is a risk that many of these travel plans are unlikely to have a great deal of influence on travel patterns, making it more unlikely that they will achieve the predicted impact on travel behaviour change, as contained in the important study and report “Smarter Choices” (Department for Transport, 2004).This paper presents results from a survey of planning and transport authorities in England, which obtained a 62% response rate from the 139 authorities contacted. It also uses the results of 18 interviews with local authority and Highways Agency staff involved in securing travel plans through the planning process. The survey found that the planning process (as opposed to voluntary efforts) is indeed the main means by which travel plans are now secured. In addition, maximum parking standards were shown to have a major influence on travel plan formation for organisations going through the planning process. There are however reasons to doubt that all of the travel plans secured through the planning process are effective. This is because:

•

Many local authorities use only planning conditions and not the more flexible (but complex) obligations which would allow more complex travel plans to be secured.

•

There is a lack of monitoring of travel plans in many authorities.

•

There is evidence that in many authority areas there are travel plans in breach of legal agreements, but these breaches are not enforced, reportedly due to a lack of monitoring, resources, and other organisational issues.

The paper discusses the reasons for these findings and also makes a number of suggestions as to how the planning system could be improved as a means of securing travel plans.     

Traffic exposure near the Los Angeles–Long Beach port complex: using GPS-enhanced tracking to assess the implications of unreported travel and locations

Traffic exposure assessments could misclassify the extent and locations of exposure if traditional recall surveys and self-reported travel diaries do not record all participant activities. The Harbor Communities Time Location Study (HCTLS) examines the nature, extent and implications of underreported locations/trips in a case study which used portable Global Positioning Systems (GPS) devices to track the diurnal patterns and traffic exposure of 47 residents of communities near the Los Angeles–Long Beach port complex. Participants were similar to adults nationwide in time spent indoors, in-vehicle, and outdoors, but spent more time indoors at home (78% vs. 66%). Overall, participants did not report nearly half (49%) of the locations and trips identified in GPS-enhanced data on their activity diaries, resulting in about 3 h/day in unreported locations and 0.6 h/day in unreported trips. The probability of a location/trip being underreported was systematically correlated with participant and location/trip characteristics. Self-reported data missed about 50 min of heightened air pollution exposures during the 5 h/day on average participants spent in high-traffic areas and about 30 min during the 4 h/day near truck routes. GPS-enhanced methods provide opportunities to more precisely characterize exposure periods and tools to identify facility, roadway, and land use types of the greatest concern for mitigation efforts.     

Differences in travel objectives between first‐time and repeat tourists: An empirical analysis for the Kansai area in Japan

This study investigates the differences in travel objectives between first‐time and repeat tourists. We conduct a questionnaire survey of travel agencies, which asked about specific tour plan for target tourists, their experiences and travel objectives in the Kansai area in Japan. We estimate a logit model for the relationship between travel objectives and visiting experiences. The results indicate that the first‐time tourists' main objective is to enjoy looking around sightseeing spots, while the repeat tourists' objective is simply to enjoy the stay, including the hotel visit and participating in events.

New SP-values of time and reliability for freight transport in the Netherlands

This paper discusses the methods used in a study on the values of time and reliability in freight transport in the Netherlands. SP surveys were carried out among more than 800 shippers and carriers. A novel feature is that both for the value of time and reliability two additive components are distinguished: a transport cost and a cargo component. Specific instructions were given to make sure that the carriers provide the former and shippers that contract out the latter component. The resulting values that will be used in CBA in The Netherlands are presented and compared against the international literature.     

Give public transit a chance: A comparative analysis of competitive travel time in public transit modal share

Extensive research has found that people are more likely to choose the transport alternative which offers shorter travel time. But few studies approached the role of travel time across different transport alternatives and cities. This research assesses the influence of competitive travel time between car and public transit in public transit modal share for commute trips. São Paulo, New York, and Tokyo were selected to perform the analysis. A Fractional Logistic Regression in the binary form was drawn, and a competitive travel time index was calculated based on the Car/Public transit travel time ratio weighted by the number of the employed population at the origin and jobs at destinations in the absence of an Origin-Destination matrix. Findings suggest that, though car ownership was identified as the major factor, Car/Public transit travel time ratio is positively associated with the increase of public transit modal share. Furthermore, the Car/Public transit travel time ratio effect in public transit modal share consistently increases as people get increased access to cars.     

Market segmentation based on time use: an empirical analysis in the historic city of Toledo,Spain

There are two major scarce resources for visitors: time and money. However, literature on tourism has paid less attention to the former than to the latter. The objective of this paper is, therefore, to evaluate the effectiveness and profitability of time use in a destination as a segmentation criterion in tourism. The empirical analysis took place in the historic city of Toledo (Spain), and was based on information obtained from 799 day-trippers and tourists. The results obtained reveal the existence of four segments as regards day-trippers and another four as regards tourists. What is more, there are significant differences in the spending and future intentions of the clusters of day-trippers and tourists. All of these findings have led us to conclude that the segmentation criterion proposed will be of great use when determining which groups of visitors the destination most/least needs to attract. The empirical evidence obtained also provides practical orientation as to how to improve activity and service offers.     

Representing protected areas: a critical discourse analysis of tourism destination building in a Greek travel magazine

The present paper examines the way protected areas are constructed as tourism destinations by the information sources (i.e. a Greek travel magazine) that are consumed by potential visitors to such areas. Specifically, it explores what form of tourism is proposed for virtual visitors, whether it is ecotourism (i.e. both tourism and environmentalism) or simply a nature‐based one (i.e. exclusively tourism). Examining the way a Greek travel magazine builds protected areas as tourism destinations, and consequently what expectations are created for readers and potential visitors to such areas, the focus of the present paper is on whether the media contribute to the failure on the part of visitors to protected areas, who are the majority of the people engaging in ecotourism activities, to incorporate environmentalist besides tourism pursuits in their travel experiences. The analysis suggests that the travel magazine cultivates the view that other protected areas (with a tradition in mass tourism) are suitable for nature‐based tourism, others (with great ecological interest) for environmentalism, but few for ecotourism. This means that visitors to protected areas will probably have a difficulty in combining tourism with environmentalist pursuits, rather than in developing environmentalist concerns in general.

Spatial analysis of access to and accessibility surrounding train stations: a case study of accessibility for the elderly in Perth,Western Australia

Approximately one-fifth of Perth’s population is aged 60 or older. Projections suggest that this proportion will continue to increase as a result of the large number of children born after the World War II (1946–1964). Access to and accessibility around train stations for the aging population is and will become a more important issue as the elderly population continues to grow. The aim of the paper is to develop and apply a new measure of accessibility to train stations at a fine spatial scale, justified by the special circumstance of the elderly using a case study in Perth, Western Australia. Intercept surveys are used to collect data on factors affecting train station accessibility for patrons aged 60 years or older, at seven highly dispersed train stations. Overall accessibility is measured separately using a composite index based on three travel modes (walk-and-ride, park-and-ride and bus-and-ride). The results illustrate that key variables, such as distance from an origin to a station, walking or driving route directness, land-use diversity, service and facility quality, bus connection to train stations, all affect the accessibility to train stations for the elderly. This implies that improvements to these factors will improve accessibility for this population group.     

Exploring the choice of battery electric vehicles in city logistics: A conjoint-based choice analysis

Adoption of electric vehicles by transport companies remains limited although major European cities should reach CO₂-free city logistics by 2030. This paper explores therefore the vehicle choice behaviour of transport companies through a conjoint-based choice analysis.The results showed that the benefits of battery electric vehicles are less valued than their disadvantages. However, a majority of respondents agrees that authorities should encourage the use of battery electric vehicles. Based on the preferences of transporters, we conclude that the most important measures are to develop a larger charging infrastructure and implement financial incentives through subsidies or tax exemption.     

Congestion and multimodal transport: a survey of cargo transport operators in the Netherlands

Longer and more frequent traffic jams in the Netherlands are increasing the costs of transporting cargo. Tightly scheduled production systems rely on punctual materials movements, but are congestion-induced delays sufficient to stimulate freight mode switching from road to combined road–rail and road–water movements? A survey of Dutch transport companies revealed an estimated 10% of vehicle operating time spent in congested conditions. The perceived impact on transport operations, consumers and service characteristics are reported. Based on the survey findings, a vehicle cost simulation attributed 7% of transport costs to congestion, increasing the attractiveness of multimodal transport and other solutions.
