{"title":"Does perceived accessibility affect travel behavior or vice versa? Alternative theories testing bidirectional effects and (in)consistency over time","authors":"Milad Mehdizadeh ,&nbsp;Maarten Kroesen","doi":"10.1016/j.tra.2024.104318","DOIUrl":"10.1016/j.tra.2024.104318","url":null,"abstract":"<div><div>In theory, the unidirectional relationship between perception and behavior has been well established. In this line, the relationship between perceived accessibility and travel behavior has also gained traction in the transport domain. There is, however, less knowledge regarding the dynamic of bidirectional effects between these two variables and (in)consistency over time. Employing the Netherlands Mobility Panel data, we investigate the direction of the (causal) effect between perceived accessibility and travel behavior/travel preference. Using a two-wave cross-lagged panel model, we test how this theory works among urban travelers (n = 4,946). The findings show that the relationship between perceived accessibility and travel-related decisions varies depending on the transport mode and whether it is about travel behavior or preference. The effects might show bidirectionality, unidirectionality, or neither. Findings highlight that the perception-behavior theory is primarily consistent with revealed travel behavior as opposed to stated preferences. We find a bidirectional perception-(travel) behavior relationship. Unlike conventional wisdom and commonly used theoretical links, we find that travel mode use has a larger impact on perceived mode-specific accessibility than the reverse effect (the more expected link). Travel behavior also shows consistently lower levels of perception-behavior dissonance than preferences do. The study finds that perception consistently influences public transport use and preferences, unlike for cars and bicycles. Policy-wise, this implies that efforts aimed at correcting misperceptions about the accessibility of public transport could still have a positive impact on individuals’ decisions to choose public transport.</div></div>","PeriodicalId":49421,"journal":{"name":"Transportation Research Part A-Policy and Practice","volume":"191 ","pages":"Article 104318"},"PeriodicalIF":6.3,"publicationDate":"2024-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142657467","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent research showed how American, Canadian, and Australian cities operationalized the concept differently using diverse temporal cut-off values and types of destinations. Despite this, there has been little effort to understand how different 15-minute city policies are comparable, and to what extent physical elements in cities can affect realizing the concept. To address this gap, this study aims to understand parallels and differences between these policies while understanding the impacts of the city’s structuring elements on the probability of achieving them. Using a wide array of spatial and transportation data for the City of Saskatoon, the paper develops five different 15-minute city policies based on four different city plans at the parcel level. Using summary statistics and multilevel logistic regressions previous policies were analyzed. The study shows considerable differences between policies in terms of the conclusions they convey. For example, different policies led to diverse results regarding their relationship with people’s socioeconomic issues, and thereby equity assessment. Additionally, the study shows that some physical elements such as highways, large parks, and rail lines have a consistent negative impact on the probability of realizing 15-minute city goals, regardless of the used policy. Other elements had a mixed effect according to the used policy. This study offers cities a better understanding of the performance of different 15-minute city policies and the relative challenges in realizing them, helping cities achieve their broader sustainability and equity goals.</div></div>","PeriodicalId":49421,"journal":{"name":"Transportation Research Part A-Policy and Practice","volume":"191 ","pages":"Article 104307"},"PeriodicalIF":6.3,"publicationDate":"2024-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142657466","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this gap, this study employs “value of children” and “demand and reward” theories to provide a conceptual framework that demonstrates how taking children to school can influence parents’ wellbeing through different channels. Using the Longitudinal Study of Australian Children (LSAC), which contains data from 10,000 Australian children and their parents, we develop a structural equation model (SEM) to examine the connections within the proposed conceptual framework. Our findings reveal that when parents accompany their children to school, it improves the quality of their parent–child relationship, leading to an increase in overall wellbeing. Furthermore, when parents and children walk to school together, it enhances parents’ physical health and wellbeing. However, using public transport to take children to school increases parents’ time pressure and undermines their wellbeing.</div></div>","PeriodicalId":49421,"journal":{"name":"Transportation Research Part A-Policy and Practice","volume":"191 ","pages":"Article 104299"},"PeriodicalIF":6.3,"publicationDate":"2024-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142657465","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is necessary in order to meet the needs of cyclists, to effectively promote cycling, and to prevent fly parking of bicycles. Therefore, this paper analyzes cyclists’ parking preferences regarding the type and placement of bicycle parking facilities. The study is based on a stated preference experiment (n = 2,960) on the bicycle parking choice behavior of university students and employees of RWTH Aachen University, one of the largest universities in Germany. The analysis employs a mixed logit model to estimate the influence of facility type and user-specific factors, the willingness to pay for parking facilities, and the relevance of cycling detours and walking distances. The results indicate that cyclists are more than twice as sensitive to walking distances than to cycling detours. Furthermore, they have a general preference for bicycle parking stations and covered versus uncovered parking racks, as well as a reluctance to use informal parking facilities. While previous research has shown that groups of cyclists have different preferences and parking behaviors, it has been unclear what factors influence group membership. This paper shows that student and employment status and the resale value of the bicycle are important user-specific factors influencing the choice between parking facilities. Furthermore, there is a notable willingness to pay for bicycle parking, especially among those with expensive bicycles. The considerable variation in preferences among cyclists underscores the importance of considering the heterogeneity of cyclists when planning parking facilities to optimize their utility.</div></div>","PeriodicalId":49421,"journal":{"name":"Transportation Research Part A-Policy and Practice","volume":"191 ","pages":"Article 104298"},"PeriodicalIF":6.3,"publicationDate":"2024-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142657462","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An airline route choice model is estimated for both full-service carriers (FSCs) and Spring Airlines, China’s largest and most representative low-cost carriers (LCCs), which disentangles the “attenuating” and “persistent” effects of the pandemic on airlines’ route choices. The former effect refers to airlines exiting from extant routes in response to the sudden decline in air travel demand and strict pandemic controls, while the latter effect reflects airlines’ relatively long-term adjustment of their competition strategy triggered by the pandemic. Our empirical findings are as follows: The pandemic had a positive “persistent effect” and a negative “attenuating effect” on Spring Airlines. Spring Airlines has actively expanded its network to all types of routes, especially the dense routes connected to major airports. FSCs also adjusted their route entry strategy by entering more thin routes connected to secondary cities (i.e., a positive “persistent effect”). The pandemic has broken the equilibrium of network differentiation between FSCs and Spring Airlines in China. Spring Airlines has begun expanding services at FSCs’ major hub airports. FSCs have also tried to serve more lucrative niche routes that were previously monopolized by Spring Airlines. Overall, we observe more frequent market contact and increasing head-to-head competition between FSCs and Spring Airlines during the pandemic, when the overall traffic volume has rebounded to the pre-pandemic level. This is probably because of the airlines’ desperate need for cash flow amid financial difficulties, forcing them to intensify competition. This could have also been facilitated by more idle aircraft/airport slot capacities reallocated from the international market to the domestic market during the pandemic.</div></div>","PeriodicalId":49421,"journal":{"name":"Transportation Research Part A-Policy and Practice","volume":"191 ","pages":"Article 104291"},"PeriodicalIF":6.3,"publicationDate":"2024-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142593485","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
