Reduced Use of Environmentally Friendly Modes of Transportation Caused by Perceived Mobility Necessities: An Extension of the Theory of Planned Behavior1

An extended version of the theory of planned behavior (TPB; Ajzen, 1991 ) was used to explain travel mode choice. As a new predictor, perceived mobility necessities (PMNs) were introduced, which are defined as people's perceptions of mobility‐related consequences of their personal living circumstances. The database consisted of a survey of 1,545 car users in 3 large German cities. Using structural equation modeling, PMNs were integrated into TPB and showed the expected significant negative effect on use of environmentally friendly modes. In‐depth interviews with 82 selected participants indicated that PMN moderates the relationship between public transportation attitude and intention. This moderator effect was confirmed by a regression analysis. The extension of TPB by PMN allows deduction of more differentiated intervention strategies.     

Psychological distance as a means of evaluation

The psychological distance of objects (e.g., things, places, other people) affects how we think about them. Research suggests that psychological proximity and distance might be also related to positive and negative evaluations, respectively. In this study, we examined whether we can infer how children aged 13–16 years evaluate objects based on their statements regarding the psychological distance between themselves and these objects. Using a mixed-methods design, we verified the relationship between evaluations of objects and whether they are perceived as psychologically close or distant, in a sample of secondary school students. School subjects were predominantly used as evaluation objects. Students used a worksheet that allowed them to visually demonstrate perceived psychological distance between themselves and objects, and then they were asked to explain their choice. Results suggested a strong association between psychological distance and positive or negative evaluation. Thus, the implications of our findings may be relevant for psychodiagnostics.     

Examining human attitudes toward shared mobility options and autonomous vehicles

This paper presents a comprehensive analysis of people’s attitudes toward shared mobility options and autonomous vehicles (AVs), with a focus on the underlying patterns and potential determinants. A stated preference (SP) survey was designed and implemented in the U.S. Four sets of questions were included in the questionnaire, each focused on one unique aspect of user attitudes, including a) preferences for mobility options and lifestyle (such as overall view of driving, factors in mode choice decisions and technology engagement), b) perceived benefits and concerns of shared mobility option, c) reasons toward or against private vehicle ownership, and d) motivations for and desired features of AVs. A structural equations model was developed to identify latent attitudinal factors and examine the correlations between the latent attitudes (as the endogenous variables) and the observed covariates (including the socio-economic and demographic characteristics, and users’ current mobility profile, such as mode use frequency, travel distance, and trip fare). The model identified eleven latent factors that represent various aspects of attitudes toward AVs and shared mobility options. The findings could be used by policymakers and Transportation Network Companies (TNCs) to a) recognize the users’ latent attitudes, b) understand the underlying patterns of attitudes, c) implement plans and policies more efficiently, d) guide or influence users’ perceptions, and e) enhance travel behavior models. This study lays the foundation for further analysis on understanding user acceptance and adoption of these emerging mobility options, which is essential to estimate the likelihood and magnitude of behavior shifts in the era of automated, connected and shared mobility.

心理距离对后悔的影响*

基于解释水平理论,考察了心理距离的不同维度对后悔程度的影响。本研究从心理距离的四个维度展开,时间距离采用组内设计,空间距离、社会距离和概率维度采用单因素完全随机设计,312名被试随机分配至各个维度参与实验处理,检验不同心理距离是否调节着后悔程度,其中有效数据275份。结果表明:在时间距离、空间距离、社会距离、概率和假设性条件下,均出现决策时心理距离越近,对决策事件或客体的解释水平越低,随后在获得负性结果反馈时体验到的后悔就越强烈。由此可见,决策事件的心理距离越近,后悔程度越大。

Introducing human factors in pedestrian crossing behaviour models

The objective of this research is the development of pedestrian crossing choice models on the basis of road, traffic and human factors. For that purpose, a field survey was carried out, in which a panel of 75 pedestrians were asked to take 8 short walking trips (each one corresponding to a different walking and crossing scenario) in the Athens city centre in Greece, allowing to record their crossing behaviour in different road and traffic conditions. The same individuals were asked to fill in a questionnaire on their travel motivations, their mobility characteristics, their risk perceptions and preferences with respect to walking and road crossing, their opinion on drivers, etc. The walking and crossing scenarios’ data were used to develop mixed sequential logit models of pedestrian behaviour on the basis of road and traffic characteristics. The modelling results showed that pedestrian crossing choices are significantly affected by road type, traffic flow and traffic control. The questionnaire data were used to estimate human factors (components) of pedestrian crossing behaviour by means of principal component analysis. The results showed that three components of pedestrian crossing behaviour emerge, namely a “risk-taking and optimisation” component reflecting the tendency to cross at mid-block in order to save time, etc., a “conservative” component, concerning individuals with increased perceived risk of mid-block crossing, who also appear to be frequent public transport users, and a “pedestrian for pleasure” component, bringing together frequent pedestrians, walking for health or pleasure, etc. The introduction of these components as explanatory variables into the choice models resulted in improvement of the modelling results, indicating that human factors have additional explanatory power over road and traffic factors of pedestrian behaviour. Therefore, the development of integrated choice and latent variables models appears to be an appropriate field for further research.     

Consumers’ intention to use environment-friendly ethical transportation medium: A conceptual framework and empirical evaluation

This study conceptualizes and tests a framework to understand consumers’ intention to use environment-friendly ethical transportation medium. It primarily uses ethical decision-making model and extends it under the purview of self-consistency theory. Based on the survey of 158 respondents and analysis of the framework using structural equation modeling and process macro, this study establishes the mediating role of moral judgement, self-accountability and perceived consumer effectiveness in forming moral intention to use ethical transportation medium. It is one of the first studies to provide insights on consumers’ intention to use environment-friendly ethical transportation medium using the ethical decision-making process. It also contributes to the literature on ethical decision-making in view of additional factors like self-accountability and perceived consumer effectiveness. The overall findings suggest new perspectives on consumers’ ethical decision-making process in the context of choice of transportation medium. The study provides some valuable guidance to the service providers and policymakers dealing with environment-friendly ethical transportation mediums.     

Multimodal traffic safety concerns in a university population

Travelers have different concerns about traffic safety, which may affect their transportation choices and risk-taking behaviors as well as the overall safety performance of multimodal transportation systems. The objective of this study was to examine factors associated with stated concerns surrounding traffic safety among travelers using multiple transport modes. The analysis used data from an online questionnaire survey completed by over 2,000 students and employees at Utah State University in Logan, Utah, US. Four latent variables—concerns about pedestrians and cyclists, auto drivers, modal interactions, and roadway conditions—were confirmed using factor analysis from 16 questions about traffic safety concerns. These four types of safety concerns were then analyzed to understand their associations with mode choice, commuting behavior, and socio-demographics using a structural equation model. Results showed that safety concern varied systematically among different mode users and demographic groups. Auto drivers perceived interactions with pedestrians and cyclists as concerning, while non-auto users felt more concerned by automobile traffic. Commuters who were recently involved in a crash were especially concerned with non-motorized modes. Women, lower-income, and non-white road users were more concerned with traffic safety overall. Findings about multimodal traffic safety concerns provide insights into people’s perceptions, which can be useful in developing designs, plans, and policies for making a safer transportation system for all road users.     

Predicting Citizen Support of Tax Increases for Education: A Comparison of Two Social Psychological Perspectives

A survey of citizen support of a proposal to increase property taxes for public education was conducted in a school district in Illinois. Two social psychological perspectives predicting support were tested. One perspective, derived from social exchange theory, predicted that citizens would base their support of or opposition to a tax increase primarily on perceived self-interested economic gain or loss. A second perspective predicted that non-self-interested concerns, such as attitudes toward the schools, would determine support of or opposition to a tax increase. Although both models received support, the strongest and mat consistent predictors of tax support among those most likely to be voters were the non-self-interested factors. Implications of these findings for public policy and for understanding political behavior are discussed.     

Revealing psychological inertia in mode shift behavior and its quantitative influences on commuting trips

The inertia effects stemmed from repeated past behavior have been investigated by both psychology and transportation studies because of its bearing on explaining human mobility and forecasting travel demand. However, the existing literature from psychology does not strictly control potential endogeneity due to ignorance of detailed level-of-service (LOS) variables of alternatives and rational preference in the analysis. Quantitative transportation studies are insufficient in providing explicit behavior mechanisms. This paper aims to fill the gaps by empirically examining the effects of irrational psychological inertia in mode shift behavior with controlling potential endogeneity. A specific-designed comparison experiment is conducted to demonstrate the existence of psychological inertia in mode shift behavior. The effects of dominance in LOS variables and rational preference towards a certain transport mode are controlled to eliminate potential endogeneity in the analysis. The results demonstrate that after controlling the above-mentioned endogeneity, both car and metro users show significantly and substantially larger predilections to previously used transport mode in mode shift scenarios without overturning travel contexts than those in new context mode choice scenarios with noticeable changes in travel contexts. The results support that psychological inertia plays a significant role in mode shift behavior after controlling potential endogeneity. Moreover, this study utilizes hybrid choice modeling to quantitatively measure the effect of psychological inertia. The relationships between travelers’ characteristics and strength of psychological inertia are analyzed as well to shed light on heterogeneity in the strength of psychological inertia. The findings provide solid evidence of psychological inertia in mode shift behavior by a novel method and provide an approach to measure the quantitative effects of psychological inertia along with empirical studies.     

An empirical investigation into carpooling behaviour for sustainability

Carpooling is a sustainable, economical, and environmental friendly solution that can significantly reduce air pollution and traffic congestion in urban areas. In spite of its numerous benefits, commuters are still skeptic about adopting it as a routine choice for transportation. This study attempts to map commuters’ attitude towards carpooling services. The study has focused on a few motivational constructs that can have an influence on commuters’ behavior. The study has looked at the role of cognitive complexity and empowerment perceptions of commuters to check if these constructs significantly intervene in the behavioral outcomes. The methodology used is a scenario-based 2 × 2 survey design where the sample is an individual who has experience with carpooling. The survey has used two levels (high, low) each of cognitive complexity and psychological empowerment to give rise to four scenarios. The final sample consisted of 400 carpoolers selected from an IT park having more than 5000 employees. MANOVA analysis showed that cognitive complexity and psychological empowerment had significant influence on the motivational constructs used in the study. Value beliefs, safety and platform quality perceptions were found to have a direct impact on attitude formation and intention to engage in carpooling behavior. The findings offer many implications for managers in the sense that that they can focus on creating suitable communication that creates favorable perceptions towards carpooling to bring about better adoption intentions.     

助推手卫生的行为干预策略

保持手卫生是感染防控的重要策略,但是如何提高其依从性成为预防传染性疾病和减少医疗机构获得性感染的一大挑战。以行为科学为基础的手卫生助推干预以更“隐性”的方式将洗手转变为一种可自动触发的行为习惯,弥补了以知识分享和健康宣教为主的传统手卫生干预策略的诸多局限性。基于影响机制的不同,手卫生助推干预策略可分为提供决策信息、优化决策选项、影响决策结构、提醒决策方向4个大类的框架体系。多模式助推策略的有效性也已在实践中得到印证,但目前还非常缺乏在中国社会文化情境下开展的助推洗手行为的干预研究,今后可尝试基于行为科学理论有针对性地在医院、学校和社区等公共场所开展此类干预研究和实践,为感染防控、疾病预防和改善公共健康做出相应的贡献。

环境损益的社会折扣:利他人格的影响

他人与自我之间的社会距离越远,则他人的获益或损失带给自我的效用就越小,此现象被称为社会折扣。虽然有一些研究探讨了金钱结果的社会折扣现象,但作为公共品的环境结果的社会折扣规律及其影响因素并未得到应有的研究。本研究以优劣空气天数为例,采用选择滴定程序,在损益两种情境下探索环境结果的社会折扣现象,并考察利他人格对社会折扣的影响。结果发现:(1)相比双曲模型,指数模型在损益两种情境下皆能更佳地拟合环境结果的社会折扣函数;(2)损益情境与社会距离的交互作用影响环境结果的社会折扣程度,损失情境下的社会折扣程度随社会距离的增加而变大的幅度大于收益情境;(3)利他人格在社会距离对社会折扣的影响中起调节作用。相比高利他人格者,低利他人格者的社会折扣受社会距离的影响较大。本研究对理解环境结果社会折扣和环保决策行为具有重要意义。     

Staying on or getting off the sidewalk? Testing the Mehrabian-Russell Model on pedestrian behavior

Social and environmental psychology provide a variety of models based on which to understand how built environments can elicit people’s behavioral responses. The Mehrabian-Russell model (MRM), initially presented in 1974, provides a framework that explains avoid–approach behavior towards a place based on a primary emotional response (PER) and affective states elicited by the perceived stimuli from the environment. However, despite the potential applications of the MRM in travel behavior studies, traditional models (e.g., discrete choice models and integrated choice latent variable) do not incorporate this specific psychological process that converts environmental stimuli into behavioral responses. Hence, this paper aims to test the applicability of MRM to urban sidewalks. To fulfill this objective, we developed a two-level structural equation model using latent variables (LV) identified from a confirmatory factor analysis (CFA) based on 1056 in-person surveys on 30 different sidewalks in Bogotá, Colombia. We then evaluated the effect of the PER on declared avoidance as a proxy of behavioral intention. The CFA uncovered three LV equivalent to the three affective dimensions of the MRM—arousal, pleasure, and dominance—followed by a fourth LV, representing the PER, which explains the three previous LVs. This confirms the applicability of these kinds of psychological and environmental models in pedestrian behavior evaluation. We found that PER can explain the declared intention of avoidance towards the sidewalk in an urban setting. Proving that this kind of model can explain the way in which the built environment can elicit pedestrians’ emotional responses and subsequent behaviors, provides information that can be used as input in travel behavior studies focusing on the promotion of active traveling and mode change.     

Research on parking choice behavior of shared autonomous vehicle services by measuring users’ intention of usage

Shared autonomous vehicles (SAVs) are one of the important development directions of smart and green transportation. However, relevant researches are not sufficient at present. The factors influencing the intention to use SAVs and their parking choice behaviors need to be further analyzed. First, in order to better explain, predict, and improve travelers’ intention to use SAVs, the conceptual framework based on technology acceptance model was developed to establish the relationships between the travelers’ intention to use SAVs, social influence of SAVs, attitude toward behavior of SAVs, perceived risk of SAVs, perceived usefulness of SAVs and perceived ease of these use. Then structural equation model (SEM) was established to analyze the relationship between various variables. The results show that the perceived usefulness, behavior attitude, social influence, perceived ease of use, and perceived risk are the main factors that determine the intention to use SAVs. Through the test of direct effect, indirect effect, and total effect in the model, it is found that perceived usefulness has the largest total impact on intention to use SAVs, with a standardized coefficient of 0.765, followed by behavior attitude (0.732), social influence (0.597), perceived ease of use (0.462) and perceived risk of SAVs (−0.452). In addition, through the study of observed indicator variables ATB2 and BI3, it is found that perceived usefulness, perceived ease of use, social influence, perceived risk, attitude toward behavior, and behavior intention all have an impact on parking behavior. In order to study the specific influencing factors of parking choice behavior, a multinomial logit (MNL) model was established to analyze the relationships between travelers’ parking choice behaviors and the influential factors, which include travelers’ individual characteristics, travel attributes, and parking modes’ attributes by extracting from a questionnaire. The results show that the travel time, travel fees, parking charge, cruising fees, parking time and traffic emission are the main factors that determine travelers’ choices of parking. This paper provides advice for operators of SAVs.

Social and Psychological Determinants of Breast-Feeding and bottle-Feeding Mothers

Our study examined the psychological and sociological factors of mothers who breast-feed and mothers who bottle-feed. Most of the data came from 124 Israeli mothers who had just given birth, but selective data were also collected on three additional samples—108, 465, and 135 new mothers. The psychological measures included the Bar-Ilan Sex Role Inventory (Tzuriel, 1984) and body image as measured by the drawing of a dressed and a naked woman. None of the psychological factors distinguished between the two groups of women. Social factors, however, did distinguish between the two groups: Mothers who breast-fed were of Asian-African background; were less educated; held blue collar jobs or did not work; perceived their husbands, relatives, and friends as supporting their decision to breast-feed; and tended to be more religious. The discriminant function analysis—which predicted 73% of the cases—showed that the mother's education, her religiousness, and her perceived support of friends and relatives were the most important factors.
