Nader KARBALLAEEZADEH, Hosein GHASEMZADEH TEHRANI, Danial MOHAMMADZADEH SHADMEHRI, Shahaboddin SHAMSHIRBAND

《结构与土木工程前沿（英文）》 2020年第14卷第5期页码 1083-1096 doi: 10.1007/s11709-020-0654-z

摘要： The most common index for representing structural condition of the pavement is the structural number. The current procedure for determining structural numbers involves utilizing falling weight deflectometer and ground-penetrating radar tests, recording pavement surface deflections, and analyzing recorded deflections by back-calculation manners. This procedure has two drawbacks: falling weight deflectometer and ground-penetrating radar are expensive tests; back-calculation ways has some inherent shortcomings compared to exact methods as they adopt a trial and error approach. In this study, three machine learning methods entitled Gaussian process regression, M5P model tree, and random forest used for the prediction of structural numbers in flexible pavements. Dataset of this paper is related to 759 flexible pavement sections at Semnan and Khuzestan provinces in Iran and includes “structural number” as output and “surface deflections and surface temperature” as inputs. The accuracy of results was examined based on three criteria of , , and . Among the methods employed in this paper, random forest is the most accurate as it yields the best values for above criteria ( =0.841, =0.592, and =0.760). The proposed method does not require to use ground penetrating radar test, which in turn reduce costs and work difficulty. Using machine learning methods instead of back-calculation improves the calculation process quality and accuracy.

Sustainable urban transportation development in China: A behavioral perspective

《工程管理前沿（英文）》 2022年第9卷第1期页码 16-30 doi: 10.1007/s42524-021-0162-4

摘要： The rapid development of economics requires highly efficient and environment-friendly urban transportation systems. Such requirement presents challenges in sustainable urban transportation. The analysis and understanding of transportation-related behaviors provide one approach to dealing with complicated transportation activities. In this study, the management of traffic systems is divided into four levels with a structural and systematic perspective. Then, several special cases from the perspective of behavior, including purchasing behaviors toward new energy vehicles, choice behaviors toward green travel, and behavioral reactions toward transportation demand management policies, are investigated. Several management suggestions are proposed for transportation authorities to improve sustainable traffic management.

摘要： The incorporation of disruptive innovations into the transportation industry will inevitably cause major upheavals in the transportation sector. However, existing research lacks systematic theories and methodologies to represent the underlying characteristics of future urban transport systems. Furthermore, emerging modes in urban mobility have not been sufficiently studied. The National Natural Science Foundation of China (NSFC) officially approved the Basic Science Center project titled “Future Urban Transport Management” in 2022. The project members include leading scientists and engineers from Beijing Jiaotong University, Beihang University, and Beijing Transport Institute. Based on a wide range of previous projects by the consortium on urban mobility and sustainable cities, this project will encompass transdisciplinary and interdisciplinary research to explore critical issues affecting future urban traffic management. It aims to develop fundamental theories and methods based on social and technological developments in the near future and explores innovative solutions to implement alongside these emerging developments in urban mobility.

《工程管理前沿（英文）》 2016年第3卷第3期页码 239-245 doi: 10.15302/J-FEM-2016047

摘要： Management of the program quality for international infrastructure construction projects is complicated. Sustainability of these programs is the key for them to succeed in their lifecycles. This paper investigated current program quality management and compared it with the results of recent surveys of KGMP. A method for the sustainable program quality management of the international infrastructure construction management is proposed and demonstrated by research projects. The cycle of accountability, predictability, balance ability, and policy was proposed. The findings from the KGMP’s survey and this research show that the trend of the sustainable program quality management of the international infrastructure construction is transferring from agility to alacrity in the balancing of the metrics among economy, ecology, culture, and politics.

Potential advantages in combining smart and green infrastructure over silo approaches for future cities

Yamuna KALUARACHCHI

《工程管理前沿（英文）》 2021年第8卷第1期页码 98-108 doi: 10.1007/s42524-020-0136-y

摘要： Cities are incorporating smart and green infrastructure components in their urban design policies, adapting existing and new infrastructure systems to integrate technological advances to mitigate extreme weather due to climate change. Research has illustrated that smart green infrastructure (SGI) provides not only climate change resilience but also many health and wellbeing benefits that improve the quality of life of citizens. With the growing demand for smart technology, a series of problems and challenges, including governance, privacy, and security, must be addressed. This paper explores the potential to transition from grey, green, or smart silos to work with nature-based solutions and smart technology to help change cities to achieve considerable environmental and socio-economic benefits. The concepts of grey, green, and smart infrastructure are presented, and the needs, benefits, and applications are investigated. Moreover, the advantages of using integrated smart, green nature-based solutions are discussed. A comprehensive literature review is undertaken with keyword searches, including journal papers, stakeholder and case study reports, and local authority action plans. The methodology adopts multimethod qualitative information review, including literature, case studies, expert interviews, and documentary analysis. Published data and information are analysed to capture the key concepts in implementing SGI systems, such as storm-water control, flood and coastal defense, urban waste management, transportation, recreation, and asset management. The paper investigates the elimination of silo approaches and the alleviation of the destructions caused by extreme weather events using these interdependent SGI systems supported by novel data-driven platforms to provide nature-based solutions to boost the health and wellbeing of the residents.

Silk Roads for the 21st Century: Engineering Mega-Infrastructure for Development and Sustainability

Tony Marjoram

《工程管理前沿（英文）》 2016年第3卷第3期页码 187-196 doi: 10.15302/J-FEM-2016038

摘要： Infrastructure facilitates the movement of people, the production and distribution of goods and services, and underpins development. Infrastructure is expensive and long-lasting, and needs long-term policy, planning and management, in terms of design, construction, operation and maintenance. Infrastructure relates particularly to engineering and technology. All technological change brings economic, social, cultural and environmental change, planned and unpredicted. Mega levels of technology bring mega levels of change, effects and impacts. Mega infrastructure such as the Silk Road Economic Belt and 21st Century Maritime Silk Road, the “One Belt, One Road” (OBOR) initiative, announced by President Xi Jinping in 2013, will require equally mega policy, planning and management. This paper will discuss policy, planning and management issues relating to mega infrastructure and the OBOR initiative, with particular reference to energy, communications, transportation, health, emergency preparedness and response, and less predictable areas of change, for example in disease prevention and control, within the overall need for economic, environmental and ecological sustainability. The paper will discuss associated needs for education, training and capacity building in engineering. The paper will also refer to lessons learnt from the original Silk Road in the context of the development of civilizations and intercultural dialogue through the transfer of goods, services, technologies, ideas, knowledge, customs, cultures and philosophies, less predictable and unwanted transfers, for example of disease, and the need for awareness, policy, planning and management of such wider issues.

Direct energy rebound effect for road transportation in China

《工程管理前沿（英文）》页码 597-611 doi: 10.1007/s42524-023-0276-y

摘要： The enhancement of energy efficiency stands as the principal avenue for attaining energy conservation and emissions reduction objectives within the realm of road transportation. Nevertheless, it is imperative to acknowledge that these objectives may, in part or in entirety, be offset by the phenomenon known as the energy rebound effect (ERE). To quantify the long-term EREs and short-term EREs specific to China’s road transportation, this study employed panel cointegration and panel error correction models, accounting for asymmetric price effects. The findings reveal the following: The long-term EREs observed in road passenger transportation and road freight transportation range from 13% to 25% and 14% to 48%, respectively; in contrast, the short-term EREs in road passenger transportation and road freight transportation span from 36% to 41% and 3.9% to 32%, respectively. It is noteworthy that the EREs associated with road passenger transportation and road freight transportation represent a partial rebound effect, falling short of reaching the magnitude of a counterproductive backfire effect. This leads to the inference that the upsurge in energy consumption within the road transportation sector cannot be solely attributed to advancements in energy efficiency. Instead, various factors, including income levels, the scale of commodity trade, and industrial structure, exert more substantial facilitating influences. Furthermore, the escalation of fuel prices fails to dampen the demand for energy services, whether in the domain of road passenger transportation or road freight transportation. In light of these conclusions, recommendations are proffered for the formulation of energy efficiency policies pertinent to road transportation.

Financing climate-resilient infrastructure: Determining risk, reward, and return on investment

Peter B. MEYER, Reimund SCHWARZE

《工程管理前沿（英文）》 2019年第6卷第1期页码 117-127 doi: 10.1007/s42524-019-0009-4

摘要：

Urban infrastructure investment is needed for both, mitigation of climate risks and improved urban resiliency. Financing them requires the translation of those benefits into measurable returns on investment in the context of emerging risks that capital markets can understand and appreciate. This paper develops a generic framework to identify what are the necessary and sufficient factors to economically favor climate-change resilient infrastructure in private investment decisions. We specifically demonstrate that carbon pricing alone will not generate the needed will, because market prices at present systematically fail to account for climate change risks such as the costs of stranded assets and the national and local co-benefits of investments in climate resiliency. Carbon pricing is necessary, but not sufficient for an enhanced private financing of climate-resilient infrastructure. The Paris Agreement and other supra-local policies and actors including city networks can concretely help to generate the sufficient social and political will for investments into climate change mitigation and resiliency at the city level.
