In this system, demand-responsive transit serves regions with lower demand, while fixed-route transit extends its service to the central business district. Subsequently, a continuous approximation model is formulated, optimizing critical network design parameters such as stop spacing, line spacing, and headway. This optimization process balances passengers' time costs, agency expenditures, and environmental considerations. A series of comparative analyses are conducted to assess the influence of incorporating emission-related costs into the network design. The inclusion of environmental factors in the design process results in an approximate 8.3% reduction in CO<sub>2</sub> emissions. Furthermore, numerical case studies are presented, encompassing a broader spectrum of key design parameters, including the value of time and variations in demand. The findings also demonstrate that the proposed hierarchical transit system exhibits lower CO<sub>2</sub> emissions when compared to the paired-line system.</div></div>","PeriodicalId":47810,"journal":{"name":"Research in Transportation Economics","volume":"109 ","pages":"Article 101496"},"PeriodicalIF":4.6,"publicationDate":"2024-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143100596","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 research examines the affordability of EVs for Irish households, focusing on equity implications and the impact of affordability on achieving decarbonisation goals. Affordability is estimated for eight scenarios, considering both current and reduced EV prices, and assessed across Ireland. The research finds that flat-rate subsidies do not adequately support lower-income households, impede EV adoption, and could jeopardise the achievement of emission reduction targets. Need-based subsidies would ensure more inclusive EV uptake. If current prices are considered, the target for the number of EVs on the road by 2030 can be met only with the purchase of small-sized EVs. This suggests that achieving EV targets is unlikely without promoting smaller vehicles. The current €3500 EV grant may be insufficient for many households without extended loan terms. Therefore, differentiated subsidies based on income and household size are recommended to increase EV adoption. Households in remote rural areas, where forced car ownership is high, require higher subsidies. In contrast, urban areas could receive lower subsidies to promote the use of more sustainable transport modes, such as cycling, shared mobility, and public transport.</div></div>","PeriodicalId":47810,"journal":{"name":"Research in Transportation Economics","volume":"109 ","pages":"Article 101495"},"PeriodicalIF":4.6,"publicationDate":"2024-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143100594","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, EU-MBM shows a deficient convergence with HSC's pollutant impact when renewable energies and alternative fuels are involved in retrofitting, by evidencing significant over grants, especially for on-shore power supply.

The results reveal three groups with considerable heterogeneity in preferences: the group accepting <em>trade-offs</em>, the <em>lone-wolves,</em> and the <em>sociable.</em> The <em>trade-off</em> group do not want to share transport, but are positive towards autonomous vehicles, and make trade-offs between these characteristics and costs. The members in the <em>lone-wolves</em> group are only concerned about not travelling in a shared transport. Members in the smallest <em>sociable</em> group are positive about sharing transports but reject autonomous vehicles. Women are overrepresented in the <em>sociable</em> group, as are people with environmental concern and those who lack a driver's licence.

Two distinct latent market segments were identified: <em>Pro-convenience</em> and <em>Pro-experience</em>, each displaying unique travel preferences measured by elasticity, first difference and willingness-to-pay. Influential factors in mode choice were found to be travel cost, access time, in-vehicle time, service frequency, and seat comfort, while females showing a higher preference for seat comfort. Advance arrival time, defined as the pre-departure waiting period at the station or airport, was found to be an insignificant factor for student travellers' mode choices.
