This paper focuses on examining public acceptance by determining the factors that affect the short-term and long-term intention to purchase an EV and drive on ERs; identifying the clusters of the technology acceptance; and assessing the value of travel time savings (VTTS) for driving on ERs, in general, and for different clusters. A survey was conducted in Los Angeles, California and distributed online, gathering 600 responses. The results showed that respondents’ innovativeness, lifestyle and environmental consciousness significantly affect the intention to drive on ERs in the short- and long-run. Public acceptance, in general, seems to be related to charging patterns, safety of commute route, and safety concerns for ERs, among other factors, and depends on the implementation time of the technology. Higher VTTS were found for electrified lanes exclusive for EVs on interstate and arterial roads. People who were classified as positive toward ERs had higher VTTS for ERs followed by those who were neutral and those who were concerned about ERs. This paper can help policymakers and transport operators devise strategies to accelerate EV adoption by appropriately implementing the ER technology.</p></div>","PeriodicalId":47824,"journal":{"name":"International Journal of Sustainable Transportation","volume":"17 1","pages":"Pages 77-101"},"PeriodicalIF":3.9,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47027577","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}

As the popularity of this relatively novel mode of travel has continued to grow, there has been a greater focus on the effect that the adoption and use of ride-sourcing have on the utilization of more traditional modes of transportation. With a few notable exceptions, prior studies on the topic often rely on descriptive statistics to understand the modes that are replaced by ride-sourcing for specific trips. This study utilizes structural equation models to investigate the factors influencing the decision to choose public transit and taxi as their so-called substitute alternative mode for a recent ride-sourcing trip, using data from a web-based survey of Toronto residents. The results indicate that socio-economic and trip-related attributes influence the selection of the substitute alternative mode, and to a lesser extent, attitudes toward ride-sourcing services. In particular, students, persons from lower-income households, and transit pass owners were found to be more likely to substitute ride-sourcing for public transit, while older respondents and persons from wealthier households were more likely to select taxi instead. The study outcomes shed light on the types of transit trips that are more likely to be replaced in favor of ride-sourcing services and the attributes of individuals who are more likely to make this replacement. This information can inform policies that aim to reduce the substitution of ride-sourcing for public transit, which can worsen both congestion and emissions.</p></div>","PeriodicalId":47824,"journal":{"name":"International Journal of Sustainable Transportation","volume":"17 1","pages":"Pages 15-28"},"PeriodicalIF":3.9,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41826473","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}

The findings suggest that the “keep left” markings on the footpath are generally effective in improving users’ behavioral intention in keeping left. However, whereas cyclists did change their behavior, pedestrians did not do so which is rationalized as being due to their previously formed habit. The findings reveal a weak intention-behavior relationship for pedestrians’ habitual behavior.

Although much scholarly attention has focused on modeling urban traffic congestion, news contents about traffic jam have rarely been examined systematically. This study selects 12 large metropolitan cities across Asia (Beijing, Bengaluru, Hong Kong, Jakarta, Kuala Lumpur, Manila, and Singapore), Oceania (Auckland and Sydney), Europe (London) and North America (Los Angeles and Toronto) for an in-depth content analysis. More than 40,000 pieces of congestion-related articles in the 2009–2018 period have been identified in the local news media of these cities. We apply techniques of text analytics to analyze underlying themes in relation to sustainable transport and congestion-mitigation measures. Also, a sentiment analysis is conducted to examine the level of frustration expressed. Results show that traffic congestion is no longer perceived to be primarily an economic issue. Concerns over the environmental impacts of traffic congestion were increasingly discussed. Based on the content analysis, cities in Asia mentioned a lot about congestion-related PM_2.5 pollution and climate change was a recurrent theme among non-Asian cities. Economic cost related to traffic congestion has received much more attention in high-income cities. With regard to congestion mitigation measures, terms related to promoting public and active transport was the most popular, followed by restriction and regulation measures, and then intelligent transport system (ITS) or smart mobility adoption. It is noteworthy that road capacity expansion has attracted the lowest coverage. Generally, high-density cities discussed more about public and active transport in alleviating traffic jams; and police enforcement was seen as important in tackling traffic congestion across all cities. In relation to the sentiment, there is a positive association between the overall traffic congestion level and the congestion frustration level expressed in local news.</p></div>","PeriodicalId":47824,"journal":{"name":"International Journal of Sustainable Transportation","volume":"17 6","pages":"Pages 592-614"},"PeriodicalIF":3.9,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44961162","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}

This new system of food consumption and provision is rapidly gaining traction, but assessments around its current and future sustainability tend to hold separate the notions of social, environmental and economic sustainability—with few to date working to understand how these can interact, influence and be in conflict with one another.

We make use of systems thinking and Campbell’s conflict model of sustainability to do this. In assessing the online food delivery in this way, we seek to not only provide a counternarrative to some of these previous assessments, but to also challenge those proposing the use of gig economy couriers as an environmentally sustainable logistics intervention in other areas of last-mile logistics to consider how this might impact the broader sustainability of their system, now and in the future.</p></div>","PeriodicalId":47824,"journal":{"name":"International Journal of Sustainable Transportation","volume":"17 5","pages":"Pages 490-502"},"PeriodicalIF":3.9,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43053119","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}

Instead, the influence of eco-consciousness on purchasing behavior is mediated by quality judgment and the product's perceived value. The study also found that consumers’ animosity affects purchase intention indirectly by eroding consumers’ perceived value of CBEVs.

Thus, sustainable solutions are needed to reduce the thermal loads affecting the truck cabins, to minimize the need for AC and decrease the sector’s costs and environmental footprint. We assessed the economic and environmental impact of AC use in the European heavy-duty transportation fleet, for realistic environmental conditions throughout the year, across the different European regions. Potential reductions were estimated for various changes in the optical properties of the cabin external paints and glazing elements (windshield and side-windows). The use of high-reflectivity paints in the cabin external surfaces and low-transmissivity glazing can reduce fuel costs by ≈€195 million/year across Europe (i.e., ≈0.1% of the total fuel costs of the European heavy-duty fleet), and decrease CO₂ emissions by 1% of the reduction target set for 2025.

The result shows that the public transportation system with both hybrid and electric buses can be good compensation between financial and environmental needs instead of using electric buses to replace all the conventional buses. Moreover, the operational plan of the public transportation system mixed with electric and hybrid buses may be adjusted according to the seasonal temperature variation so as to maximize the environmental benefits.
