Commuting between an origin and destination pair is one of the most critical components of an individual's daily activity, and the associated trip satisfaction significantly influences a commuter's well-being. Owing to negative externalities associated with urban travel such as increased congestion, poor roadway infrastructure, inadequate and unreliable public transport system, safety and security concerns, a reduction in perceived trip satisfaction could be observed among Indian commuters. Thus, it is prudent to analyze commuters' perception towards associated trip satisfaction and related components for formulating policy instruments to improve commuters' experience. This paper identified the key determinants of perceived satisfaction related to different types of trips in the Indian capital New Delhi. A Travel survey questionnaire was designed to elicit commuters' perceived satisfaction associated with daily, work, and non-work trips. Based on 898 responses, a set of ordered logit models were estimated. It was found that socio-demographic factors such as gender and age, accessibility and built-environment characteristics such as streets' level of congestion, availability and existing condition of sidewalks, bus stop safety, and security were significant determinants of commuters' trip satisfaction. Results also indicated that the choice of mode and associated safety perception played a vital role in commuters' trip satisfaction levels. Public transport users were less satisfied compared to the car commuters for both work and non-work trips. Based on the findings, a set of policy measures such as illumination of roadways, reduction in street-congestion levels, up keeping existing sidewalks, improving public transportation accessibility, etc. could be implemented for enhancing the trip-satisfaction level of urban commuters belonging to a typical metropolitan city of a developing country like India.

Following the directives set by the European Union, Greece is entering a transition phase towards electromobility. The presence of electric vehicles on the Greek market is currently low relative to other countries. The Greek government has recently established new legislation introducing financial and tax incentives towards electric vehicle purchase for both private owners and companies. This paper investigates the perspectives of a group of stakeholders in response to this government initiative. Findings indicated that the financial and tax incentives set by the Greek government were a good first step towards the promotion of electric vehicles. However, aiming at an increased penetration rate of electric vehicles on the Greek market requires strategic allocation of public charging infrastructure and national coverage to enable electric vehicles to travel within and out of the urban core. Incentives should be also considerate of different socio-economic segments of the population to prevent inequalities and match their preferences. Also, the electricity provider should ensure that the network would be able to withstand the increased electricity demand that the public charging points and electric vehicles would require. Finally, successful transition towards electromobility would require promotion of electric vehicles as an act of environmental consciousness.

Accelerating the adoption of electric vehicles provides a rare historic opportunity for reducing the dependence on fossil fuel and decarbonising road networks in the field of transport. Many countries have introduced various policy packages on both national and local levels to encourage electric vehicle adoption, but their market shares remain low. For better understanding the reasons behind this evidence, exploring the determinants that influence consumers’ adoption intentions is significant. Previous literature reviews have made clear and elaborated syntheses of influential factors; however, a summary of how evidence can be translated into policy through these factors is lacking. In response, this paper synthesises the main policies of various countries, summarises the previous research results, and forms corresponding policy tools, which can provide a reference to policymakers and guide the policy-making process.

The environmental impacts of material production, processing and consumption are profound and increasing. The aim of this study was to examine the extent at which consumers of diverse products – specifically, cars and mobile phones – valued the sustainability of materials resourced to make them. Using two choice experiments in Germany, India, Japan, Sweden, the UK and the US (total N = 6,033), we found that economic and functional attributes dominated product choice. Respondents placed relatively little or no value on ethically- or sustainably- sourced materials whereas non-conventional (organic) materials were important only in some countries. The overall low average scores of self-reported knowledge (4.8 for cars and 4.7 for mobile phones; score range 1–10) and salience about the sustainability of vehicles and phones (5.7 for cars and 4.9 for mobile phones) were partially consistent with this relatively limited influence of the sustainable materials on product preferences. Findings showed considerable cross-national differences in consumer knowledge, preferences and willingness to pay. For example, respondents from all countries except the US placed a significantly positive value on cars made of ethically-sourced-organic materials with marginal willingness to pay values ranging from a minimum of €1,951 in Germany up to a maximum of €4,524 in the UK. In the case of mobile phones, respondents placed both positive and negative values against alternative materials relative to conventional materials, which was the reference case. Also, there was disparity between self-reported sustainability knowledge/concerns and experimental product choices. Policymakers should consider further economic and/or education measures to facilitate consumer demand for products made of sustainable-materials.

This paper examines how visitor travel-mode choices to festivals are formed and how sustainable travel could be encouraged. The empirical analysis focuses on Hay Festival of Literature and Arts using semi-structured interviews with visitors. Themes and topics explored through the interviews were informed by theories of travel behaviour. Findings highlight a range of external and internal factors influencing visitor travel-mode choices, which are closely interrelated. External factors reflect environmental elements related to the location and type of overnight accommodation, festival location, travel time and quality of public transport services. Internal factors include autonomy in travelling different routes and times, travelling with young children, cost of travel and physical-health and mobility issues. An additional internal factor was routine use of the car and extension of this behaviour when travelling to the festival. Based on the consolidation of the empirical findings, this paper also proposes a new theoretical framework for capturing a more comprehensive understanding of event related travel decisions. To encourage further sustainable travel, festival organisers and policy makers should not only focus exclusively on travel time and cost but consider a wider array of factors that are unique to festivals and their geographic locations.

This chapter reports the findings of a recent study, which aims to quantify the land value benefits of public transport infrastructure. The empirical investigation focuses on central Cardiff, Wales, where data comprising approximately 9000 property sale records were collected in the period 2000–2009. Through an exploratory and explanatory spatial data analysis, it was found that: (a) there is an underlying bus stop-oriented spatial dependence of the values of residential land, which varies based on the types of housing property (e.g. detached house, semi-detached house, flat) across different areas in Cardiff; (b) after controlling for spatial dependence, there is still a significant positive correlation between bus stops and change in land value. Most importantly, different types of property seem to benefit differently from land value uplift due to bus stop locations. The highest benefits are identified for flats and semi-detached homes followed by terraced and detached homes. The corresponding price gains range from 1.4% for flats to 0.7% for detached homes.

In this chapter, a modeling exercise is carried out to analyze the factors influencing the journey-to-work by public transit in the largest two Canadian urban centers: Toronto, Ontario and Montreal, Quebec. Transit trip generation at the census tract level for the year 2011 is regressed against urban form and network design variables after controlling for several socio-economic and demographic variables. The simultaneous auto-regressive (SAR) modeling approach is employed to account for the presence of spatial dependencies in the modeled data. These spatial effects are usually neglected in travel demand models, leading to bias in the estimates obtained. While the estimated socio-economic and demographic parameters reinforce previous findings from the literature, the inclusion of urban form and network design variables offers new insights regarding the role that urban planning can have on transit trip generation. The results reported in this chapter can, thus, help promote sustainable urban planning policies.

There is an increasing concern about the growth of car dependence and its associated negative impacts on cities, including economic and environmental factors, urban form and lifestyle. City authorities worldwide now pay increasing attention to sustainable transport systems by enhancing or introducing public transit services. An example is Riyadh City, Saudi Arabia, which has witnessed a significant growth in car ownership and population. Current efforts to reduce high dependence on private cars in Riyadh involve the development of a new public transport system. Against this background, this paper considers the wider impacts of the new public transport system in Riyadh City on urban form, economics, environment, social norms and culture. The analysis is based on in-depth interviews conducted with transport experts and officials of relevant authorities in Riyadh City. The study results highlight that the city’s urban form would have the highest impact on the uptake of public transport. Moreover, stakeholders assumed that the provision of public transport services in Riyadh would improve mobility, decrease travel time, and create more employment opportunities, positively affecting Riyadh City’s economy and the environment. Interviewees concluded that these potential interventions would affect social norms and culture positively in the long term.

This paper examines public preferences regarding privacy implications of internet surveillance. The study was based on a pan-European survey and included a stated preference discrete choice experiment (SPDCE) involving the choice of an Internet Service Provider (ISP) offering varying levels of storage, access and sharing of internet activity, continuous surveillance and privacy enhancing technologies. The survey obtained 16,463 individual responses across the European Union's 27 member-states 1 . Respondents expressed highest levels of concern about: Internet facilitated crime, namely using the internet to share and publish child pornography (68.2%); individual data protection and security threats – i.e., personal information not being handled in a legitimate way (62%); computer viruses (61.4%) and finally the theft of financial data or identity (61.4%). Such levels of concern affect trust in the Internet: 27.7% of respondents trusted websites for information exchange and a similar figure, 30.7% reported they trust websites for business transactions. Given this context, following our analysis of preferences, on average, respondents were more likely to choose an ISP that would not store any internet activity, would retain any data for up to 1 month and would not share data with anyone else. Interestingly, respondents did recognise the potential benefit for continuous state-surveillance (by the police), but only under an appropriate accountable legal basis. Also, respondents were in favour of an array of privacy enhancing technologies that would enhance their privacy when using the Internet. Finally, the analysis shows that in some cases, significant differences in preferences across countries and socio-economic characteristics suggest that individual privacy-preferences do vary across cultural/national settings, age, gender and education level.

This paper reports on the factors associated with non-fatal urban-road accident severity. Data on accidents were gathered from the local traffic police in the City of Palermo, one of the six most populated cities in Italy. Findings from a mixed-effects logistic-regression model suggest that accident severity increases when two young drivers are involved, road traffic conditions are light/normal and when vehicles crash on a two-way road or carriageway. Speeding is more likely to cause slight or serious injury even when compared to a vehicle moving towards the opposite direction of traffic. An accident during the summer is more likely to result in a slight or serious injury than an accident during the winter, which is in line with evidence from Southern Europe and the Middle East. Finally, the severity of non-fatal accident injuries in an urban area of Southern Europe was significantly associated with speeding, the age of the driver and seasonality.

In an effort to reduce traffic congestion and excess dependency on private vehicles in Riyadh City, authorities are considering introducing public transport infrastructure and enforcement policies. This study was conducted to evaluate whether the current Riyadh City transport policy measures are adequate to encourage public transport ridership and identify relevant transport policy measures to encourage a shift from use of private cars to public transport. A series of semi-structured interviews were conducted in Riyadh during June and July 2015. Seventeen study participants were selected to represent local stakeholders including transport experts and representatives of Riyadh City authorities. It was found that existing transport policy measures involve conventional approaches, for example, increasing road infrastructure to match growth in private vehicle ownership. There is, however, considerable support for reshaping the existing travel demand management policies and measures along with introducing a public transport system. Improving infrastructure to enhance accessibility to and from transit stations, selecting appropriate transit-oriented development sites, parking charges, separate carriages for families, and promoting the safety of public transport facilities are perceived as the most effective strategies.

Objectives (1) To test the use of best–worst scaling (BWS) experiments in valuing different types of biomedical and health research impact, and (2) to explore how different types of research impact are valued by different stakeholder groups. Design Survey-based BWS experiment and discrete choice modelling. Setting The UK. Participants Current and recent UK Medical Research Council grant holders and a representative sample of the general public recruited from an online panel. Results In relation to the study's 2 objectives: (1) we demonstrate the application of BWS methodology in the quantitative assessment and valuation of research impact. (2) The general public and researchers provided similar valuations for research impacts such as improved life expectancy, job creation and reduced health costs, but there was less agreement between the groups on other impacts, including commercial capacity development, training and dissemination. Conclusions This is the second time that a discrete choice experiment has been used to assess how the general public and researchers value different types of research impact, and the first time that BWS has been used to elicit these choices. While the 2 groups value different research impacts in different ways, we note that where they agree, this is generally about matters that are seemingly more important and associated with wider social benefit, rather than impacts occurring within the research system. These findings are a first step in exploring how the beneficiaries and producers of research value different kinds of impact, an important consideration given the growing emphasis on funding and assessing research on the basis of (potential) impact. Future research should refine and replicate both the current study and that of Miller et al in other countries and disciplines.

Objective To assess the public’s preferences regarding potential privacy threats from devices or services storing health-related personal data. Materials and Methods A pan-European survey based on a stated-preference experiment for assessing preferences for electronic health data storage, access, and sharing. Results We obtained 20 882 survey responses (94 606 preferences) from 27 EU member countries. Respondents recognized the benefits of storing electronic health information, with 75.5%, 63.9%, and 58.9% agreeing that storage was important for improving treatment quality, preventing epidemics, and reducing delays, respectively. Concerns about different levels of access by third parties were expressed by 48.9% to 60.6% of respondents. On average, compared to devices or systems that only store basic health status information, respondents preferred devices that also store identification data (coefficient/relative preference 95% CI = 0.04 [0.00-0.08], P = 0.034) and information on lifelong health conditions (coefficient = 0.13 [0.08 to 0.18], P < 0.001), but there was no evidence of this for devices with information on sensitive health conditions such as mental and sexual health and addictions (coefficient = −0.03 [−0.09 to 0.02], P = 0.24). Respondents were averse to their immediate family (coefficient = −0.05 [−0.05 to −0.01], P = 0.011) and home care nurses (coefficient = −0.06 [−0.11 to −0.02], P = 0.004) viewing this data, and strongly averse to health insurance companies (coefficient = −0.43 [−0.52 to 0.34], P < 0.001), private sector pharmaceutical companies (coefficient = −0.82 [−0.99 to −0.64], P < 0.001), and academic researchers (coefficient = −0.53 [−0.66 to −0.40], P < 0.001) viewing the data. Conclusions Storing more detailed electronic health data was generally preferred, but respondents were averse to wider access to and sharing of this information. When developing frameworks for the use of electronic health data, policy makers should consider approaches that both highlight the benefits to the individual and minimize the perception of privacy risks.

Consumers' privacy concerns remain the primary barrier for future growth of e-commerce. Research to date has so far considered privacy concerns either as an independent variable to explore consumers' actual (or stated) behavioural intentions (e.g. the decision to purchase goods online) or as dependent variable explained through a number of antecedents (e.g. privacy awareness). However, there has not been a formal link across antecedents, latent constructs and (stated) behavioural intentions. This study establishes this link through a stated choice experiment, and an integrated latent variable and choice model. The proposed approach simultaneously explains individuals' perceptions of privacy and general caution through observed individual characteristics and explores how these perceptions, in the form of latent constructs, may be associated with consumers' decisions to engage with an online transaction. The stated choice experiment is designed to collect consumers' choices across online retailers, a conventional store and an opt-out option in which online retailers are presented with varying levels of personal-information requirements. The data was collected come from over 500 respondents representing the online-user population in the UK. Model estimation results show that the higher an individual's privacy concern, general caution and technical protection, the less likely a consumer is to purchase a product online. In a joint model, the privacy concern variable is found to outweigh the effect of general caution and technical protection. Finally, consumers with higher levels of general caution are more sensitive towards an online retailer that shares their personal data with third parties.

Based on a multilevel and quantile hedonic analysis regarding the local public bus system and the prices of residential properties in Cardiff, Wales, we find strong evidence to support two research hypotheses: (a) the number of bus stops within walking distance (300–1500m) to a property is positively associated with the property's observed sale price, and (b) properties of higher market prices, compared with their cheaper counterparts, tend to benefit more from spatial proximity to the bus stop locations. Given these statistical findings, we argue that, land value tax (LVT), albeit a classic political idea dating back to the early 20th century, does have contemporary relevance and, with modern geographic information technologies, can be rigorously analysed and empirically justified with a view to actual implementation. Levying LVT will not only generate additional fiscal revenues to help finance the development and maintenance of local public infrastructures, but will also ensure a more just distribution of the economic welfare yielded by public investment

Disjoint research efforts have so far considered latent constructs (e.g. privacy concerns) either as an independent variable to explore consumers' actual or stated intentions or - to a less extent - as dependent variable explained through a number of antecedents (e.g. privacy awareness, demographic differences). However, there has not been a formal link across antecedents, latent constructs and behavioural (or stated) intentions in the context of ecommerce or information disclosure. This paper aims to fill this gap in the literature in order to establish a better understanding of the role of attitudes in respondents' willingness to engage in online purchases. We employ a stated preference discrete choice experiment to collect respondents' choices across online retailers, conventional store and opt-out options under different levels of personal-information requirements. Personal information in the experiment is presented across three dimensions (attributes): amount/type of information collected, duration of storage and the likelihood of this information being shared with third parties. These dimensions are introduced in order to be able to capture risks involved in online transactions according to consumer perceptions. Using the Privacy Calculus as a guiding conceptual framework, the experiment also offers respondents trade-offs between benefits such as faster check-out, detailed reviews and priority shipping of the purchased product. The choice data are complemented with a set of attitudinal indicators (psychometric scales) describing individuals’ attitudes toward information privacy protection. The data comes from 502 participants representing the online-user population in the UK. We report results from Integrated Latent Variable models, which test the influence of these latent constructs in the consumers' decision to purchase a product online and their sensitivity upon attributes describing online retailers.

Privacy issues related to mass surveillance received unprecedented attention in 2013 and 2014. While the debate so far has focused on internet-based surveillance, the concerns raised by increased awareness of state surveillance capabilities have far reaching consequences for discussions on legislation relating to security, privacy and liberty in a range of domains.Focusing on train/metro travel we investigate whether Europeans perceive similar security and privacy issues as have been raised in recent discussions about surveillance. This paper presents preliminary findings from the empirical phase of PACT, a three year pan-European project. PACT has as its centerpiece a large scale survey of privacy & security preferences. The survey is designed to elicit respondents’ preferences related to various security and privacy aspects involved in three contexts, including train/metro travel. Using data from the pilot we demonstrate the application of stated preference methods in the context of security and privacy. The stated -preference exercise gathers preferences related to CCTV, CCTV data handling, type of security personnel, type of physical security check, delay due to security checks, and cost of security/surveillance. Using discrete choice models to estimate willingness to pay for different security/surveillance features we aim to provide the missing evidence on valuation of public security and surveillance
