Yet, limited research has examined how factors such as residential location, residential parking type, and workplace parking payment type (e.g., self-paid or employer-paid) influence PAV parking choices and associated empty-cruising vehicle-kilometres travelled (VKT). This study addresses these gaps using survey data collected from 526 commuters driving to Central Melbourne, Australia. We employ both random forest (RF) and multinomial logistic regression (MNL) models to investigate factors influencing different parking options. The MNL results show that commute time, household composition, residential parking type, region, age, housing type, and walking time are key determinants of preferences for sending PAVs home. Meanwhile, education, household composition, region, and car ownership influence preferences for free suburban parking. These results align with RF model importance rankings, where commute time (19 %) and household composition (11 %) were the top predictors. Additionally, sending vehicles home could generate 13 % more VKT compared to current commuter patterns. These findings have implications for managing future CBD parking supply, regulating empty cruising, and shaping land use and pricing strategies for PAV-era mobility.</div></div>","PeriodicalId":47810,"journal":{"name":"Research in Transportation Economics","volume":"114 ","pages":"Article 101651"},"PeriodicalIF":3.4,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145333998","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To ensure robust results, the analysis incorporates three control variables: port congestion index, container trade index, and container fleet growth. The findings reveal an inverted N-shaped relationship between inflation and freight rates, with two inflection points demarcating shifts in the direction of the effect: inflation exerts a positive influence within the range between the two points but a negative influence outside it.

Such trends make efforts to reduce reliance on private transport more challenging. We assess the effect that knowledge of an impending haze event has on parents' transport mode decisions for their primary school child's school commute. We exploit a randomized experiment embedded within a survey to tease out the incremental effect of varying transboundary haze severity (Band 2: Elevated, Band 3: High, Band 4: Very High) on parents' preference to send their child to school via “closed” transport modes. We find that while haze increases parents' motivation to switch to “closed” modes of transportation, the effect is not linear.

Then, the BK-frequency model further demonstrates that positive spillovers from TPU to various shipping variables, such as freight-rate indices and vessel prices, emerge after two weeks and intensify over six months. Moreover, under extreme TPU drops, the long-term (>26 weeks) spillover effect on the shipping system becomes more pronounced, highlighting the restored confidence among industry practitioners following the easing of trade tensions. Finally, considering current industry practices, the direction of trade policy after the 90-day suspension period is pivotal, as it coincides with the peak season for container shipping, potentially driving a decrease in freight rates amid new tariffs and inventory shortfalls.

Limited coverage with standard congestion tolling results in clustered economic activities and populations for both labor market structures.

Drawing on behavioural insights from Kahneman's book ‘Thinking, Fast and Slow’, which investigates how subtle cues influence decision-making. Two online surveys using a randomized experimental design tested nine nudging strategies. Among these, financial penalties and eco-label prompts proved most effective in encouraging slower delivery choices. Participants with prior pro-environmental awareness were less inclined to choose an express delivery, while older Gen Z respondents (closer to 30) tended to favour express delivery regardless of the nudge, suggesting that lifestyle differences shape responsiveness to nudges. These findings indicate that the success of a nudge depends not only on its design but also on consumers' prior awareness and demographic profiles.
