This paper examines what influences the demand for AFVs and CVs in the UK’s large automobile market, looking at vehicle attributes, prices, and other factors, such as brands, country of origin, car segments, and vehicle equipment. Using an extensive, unique dataset covering the period 2008–2019, we compute own-price, cross-price, and demand elasticities for CVs and AFVs. Applying a random-coefficient discrete-choice model of demand, and controlling for consumer heterogeneity, unobserved product characteristics, and price endogeneity, we find that the key drivers of demand are prices, fuel consumption, and vehicle size, with similar demand sensitivity between CVs and AFVs. Demand falls by 3%–5% for a ₤1,000 increase in price for both CVs and AFVs, conditional on the quality and availability of substitutes. This indicates that UK consumers are not willing to pay a price premium for AFVs, suggesting little value placed on the “greenness” of AFVs. We estimate that a ₤1,000 subsidy to AFV purchases would lead to 4% of consumers switching to the greener vehicles. While CVs and AFVs exhibit similar price elasticities, vehicle size affects AFV demand by about 40% more, as their purchasers value smaller sized vehicles. Our results indicate that without financial incentives, the uptake of AFVs may remain low, as the higher cost and lower convenience outweighs the environmental considerations for the majority of consumers.</div></div>","PeriodicalId":49421,"journal":{"name":"Transportation Research Part A-Policy and Practice","volume":"190 ","pages":"Article 104284"},"PeriodicalIF":6.3,"publicationDate":"2024-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142529609","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 study fills-up the literature gap by implementing individuals’ work-arrangement and introducing in-home (IH) virtual activities within an integrated Transport, Land-use, and Emission (iTLE) modeling framework. First, it conducts a household travel survey, which collected socio-economic, activity-travel, and work-related information through a questionnaire survey in the Halifax Regional Municipality (HRM), Nova Scotia, Canada. Next, it develops a work-arrangement choice model based on the mixed-logit modelling (MXL) approach and implements it within iTLE. After that, individuals’ daily activity programs are generated in a sequential manner utilizing a Markov Chain Monte Carlo (MCMC) modelling approach considering their work-arrangement, employment, and vehicle ownership. To demonstrate the application of the developed tool, individuals’ socio-demographics, residential-location, work-location, and activity-participation are longitudinally simulated up to 2031. The analysis of teleworking parameters revealed distinct clusters and individual preferences, emphasizing the significance of personalized approaches in formulating teleworking strategies. Most non-teleworkers stay closer to downtown than full-teleworkers while clustered behavior is observed among hybrid workers for residential location choice. Increase is observed for shopping, dining-out, and IH maintenance/discretionary activities while decrease is observed for out-of-home work.

This study presents a novel quantitative analysis methodology from a trip-level perspective based on multi-source data to explore the relationships between dockless bike sharing and public transport without reliance on geospatial thresholds. By utilizing a comprehensive dataset encompassing bike sharing service operations, public transit facilities, and optimal route choices, we introduce the concepts of degree of site proximity (DSP) and degree of trip substitution (DTS), which are designed to assess the opportunities for cooperation and competition in DBS trips. Clustering techniques categorize recorded trips into specific types: competition, cooperation, cooperation-competition, and independence. A survey of dockless bike sharing users in Shanghai, China was conducted to obtain data on usage of DBS and the alternative choices without DBS. A comparison between the survey results and the estimates from the proposed methodology validates its effectiveness. In-depth analyses of factors such as weekends, cycling distances, and station densities reveal patterns of variation in the relationship between DBS and public transport systems.

Drawing from a sample of 3,381 Swiss public transport customers utilizing either the pay-per-use option or holding a flat-rate subscription, a binomial logistic regression highlights that the number of passenger kilometers traveled (pkm) predominantly influences the choice of a flat rate. However, the examined psychological factors also significantly shape decision-making. Notably, these effects vary based on the quantity of the product consumed. Specifically, both the taximeter and cost-control effects tend to increase with pkm. Conducting a simulation using binomial logistic regression, we illustrate how different psychological factors are related to the likelihood of opting for a flat-rate subscription. The findings suggest that the level of importance of the psychological factors are relevant to predict the odds of selecting a flat-rate subscription. Hence, emphasizing product advantages in marketing communications and strategically adjusting product design to leverage these psychological factors emerge as effective strategies for enhancing sales promotion and fostering customer loyalty.

Activity-based accessibility, a utility-based accessibility measure, is used to reflect the AV impacts on short-term travel demand. The year 2040 is set as the backdrop for the analyses, where the effects of the decreased population are reflected in the scenario settings, along with variables such as decreased travel impedance to accommodate the uncertainties in the characteristics of AVs. The simulation results of four AV scenarios confirm the potential of urban expansion. The results demonstrate that, compared to the Base Scenario, the median distances between the residences and the closest Dwelling Attraction Areas, representing as the target for attracting residences by the local government, expand by 5.2% to 10.2% for the AV scenarios. Two hypothetical policy mandates are then applied to alleviate the problem. The results indicate that providing a 10% subsidy to the land price might be effective to mitigate urban sprawl for the scenario with relatively conservative AV settings. Nonetheless, the substantial cost associated with implementing such a policy renders it effectively unfeasible and underscores the need for proactive planning in anticipation of a level 4 or 5 Automated Vehicle future.</div></div>","PeriodicalId":49421,"journal":{"name":"Transportation Research Part A-Policy and Practice","volume":"190 ","pages":"Article 104281"},"PeriodicalIF":6.3,"publicationDate":"2024-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142425163","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}
