Comprehensive review from holistic perspective is crucial and missing. This research aimed to offer comprehensive and critical research insight, identify gaps, and propose future directions by analyzing and synthesizing the complete research spectrum of city logistics sustainability assessment. Systematic literature review with iterative approach was applied and 299 articles from Scopus and Web of Science databases were selected and reviewed through content analysis. Results revealed that “transport” and “collaboration” were the most addressed research themes whereas “infrastructure” was the least investigated. Regarding the method practices, findings indicated the prevalence of “indicator system” method group in almost all research themes, except “transport” and “planning” in which “performance evaluation model” and “multi-criteria decision-making” method groups were preferred. As for sustainability coverage, “abiotic”, “resource”, “cost”, and “society” related aspects of sustainability were commonly addressed among studies whereas “biotic”, “earning”, and “city” related aspects were often neglected. In terms of indicator selection, results pointed out the heterogeneity and lack of consensus among studies under current research practices. Through in-depth review analysis, this study proposed comprehensive indicator framework for researchers to provide guidance on future indicator selection processes, offered critical literature insight into existing city logistics sustainability initiatives and their effects on city logistics sustainability for policy makers to consider trade-offs among various initiatives for better decision-making processes, and identified gaps and the way forwards to assist researchers for further advancing the research domain.</div></div>","PeriodicalId":36621,"journal":{"name":"Transportation Research Interdisciplinary Perspectives","volume":"33 ","pages":"Article 101603"},"PeriodicalIF":3.8,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145045301","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, this approach has notable shortcomings, including drivers’ tendency to underestimate their speeds, speed creep, and insufficient consideration of vulnerable road users, which may conflict with the Safe System Approach and Vision Zero initiatives endorsed by the USDOT (US Department of Transportation). In contrast, context-sensitive approaches, which classify roads based on roadway typologies, have been developed in countries like New Zealand, Sweden, the Netherlands, and Australia. While effective, these approaches have largely been applied outside the US, leaving many US roads with speed limits that may not fit their surroundings or adequately address pedestrian and cyclist safety. Drawing on New Zealand’s One Network Framework, we developed a US-based, context-sensitive roadway classification framework for urban and suburban areas that incorporates “<em>Place,”</em> which captures surrounding land uses and locational contexts, and “<em>Movement,</em>” which relates to the road’s transport function. Using nationally available data from the Smart Location Database (SLD) and the Highway Performance Monitoring System (HPMS), we evaluated our roadway classification framework through internal reviews by our research team and external interviews with state-level practitioners, uncovering both opportunities and challenges in adopting a context-sensitive SLS approach in the US. Our findings demonstrate the feasibility of creating an objective context-sensitive roadway classification in the US and offer insights for developing new speed-limit guidance aligned with the Safe System framework.</div></div>","PeriodicalId":36621,"journal":{"name":"Transportation Research Interdisciplinary Perspectives","volume":"33 ","pages":"Article 101621"},"PeriodicalIF":3.8,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145007556","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most research on the misallocation has only qualitatively considered the negative effects of government intervention on capital or labor. Actually, the structure of mileage scale is more important in the process of transportation resource allocation. To examine the characteristics of resource misallocation in China’s toll expressway sector and clarify the effects of government intervention on such misallocation, we first quantified three misallocations. Employing a dynamic panel model and moderating effect model, we investigated the internal mechanisms of government intervention on resource misallocation in China’s expressway sector. Empirical results revealed four key results. (1) Toll expressways have serious resource misallocation. Government intervention corrects these misallocations, especially mileage scale structure. (2) The corrected effect of government intervention on misallocation shows a significant heterogeneity. Government intervention has a more corrective effect for the operating toll expressways, companies and areas with excessive allocation of toll expressway resources, eastern regions of China. (3) Industrial agglomeration plays a dynamic regulatory role in the process of government intervention to correct misallocation. At an optimal level, government intervention facilitates the ameliorate of misallocation. (4) The same role also exists in factor marketization strengthening the correction. However, the corrective effect of government intervention has a critical value.

Maintaining a conventional approach to transportation, which is resource-intensive and environmentally damaging, and pursuing incremental emission reductions is no longer sufficient to achieve sustainable transport in DCs. Thus, in developing countries, incremental transport decarbonisation strategies, often based on regulation of the automotive sector, cannot address the complexity of transport emissions and meet the ever-growing demand for mobility. Transport systems in developing countries are not yet tied to a carbon-intensive and car-centric system, but the trend is increasingly moving in this direction. This offers the possibility of “environmental leapfrogging”, a path or process adopted by latecomers to surpass the carbon-intensive and car-centric paths pursued by others. Leapfrogging in the transport sector, defined in this paper as any low-carbon and locally relevant mode of transportation adopted by latecomers, is thus an alternative pathway for developing countries. Using Ethiopia as a case study and data obtained through document analysis, interviews and observation, this paper discusses the prospects of developing countries towards a sustainable low-carbon transportation system. The adoption of active and public transportation and the integration of transport networks are fundamental components of this system. Electric vehicles, commonly associated with leapfrogging, offer further potential in the medium to long term. However, several political, economic and institutional obstacles need to be overcome. This would require the development of clear strategies and instruments, the strengthening of the institutional framework and expanding levellers (such as knowledge and innovation centers and local enterprsies).</div></div>","PeriodicalId":36621,"journal":{"name":"Transportation Research Interdisciplinary Perspectives","volume":"33 ","pages":"Article 101613"},"PeriodicalIF":3.8,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144932724","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

ABM simulates travellers’ behaviour and SAEVs deployment strategies, yielding dynamic patterns along a typical day, while LCA provides a structured framework for assessing the life cycle environmental impacts. This process involves creating an ABM that reflects a representative mobility scenario, and a modified ABM scenario where private car and bus trips are replaced with SAEV services. The analysis extends the different scales, providing both short-term and long-term perspectives on LCA impacts. Findings revealed significant reductions in global warming potential (up to 91%), but challenges include increased operational intensity, human toxicity (up to 240%), and mineral resource scarcity (up to 229%).
