Authors: Jiang Wen , Zhang Li , Liu Menglin 
Published: April 2020

Abstract
Under the cap-and-trade and the incentive of emission reduction bonus, we investigated a two-stage construction supply chain consisting of a subcontractor with capital constraints and a general contractor. Firstly, this paper constructed a decision model of emission reduction considering both internal financing and external financing (i.e. mix financing). Secondly, the optimal decisions and maximum profit of both parties are obtained. In addition, this study also showed that the total amount of emission reduction of the general contractor increases in carbon trading price; the total amount of emission reduction of the subcontractor increases in carbon trading price and decreases in external financing interest rate; the optimal proportion of internal financing increases in internal financing interest rate while decreases in external financing interest rate.
Brief Analysis on the Design Points of the Site Selection for the Relocation of Airports in the Branch Line—Taking the Relocation of Nanyang Airport as an Example
Authors: Ruifang Su , Rui Sun 
Published: April 2020

Abstract
With the continuous enhancement of state support, China’s civil aviation has ushered in an unprecedented period of development. At the same time, along with the continuous expansion of urban construction land and the large number of new urban infrastructure building, the existing land use of regional airports in some small and medium-sized cities in China has contradicted the urban development direction and non-airport infrastructure construction. The more cities began to relocate the existing regional airports. Taking the Nanyang Airport relocation project as an example, this paper starts from the four aspects which are civil aviation status and development constraints, the influencing factors and necessity analysis of airport relocation, civil aviation development prospects and scale prediction, and the factors affecting the site selection of airport relocation. Based on the above analysis, we propose the basic framework, research methods and implementation strategies for the location of the relocation of the regional airport, which are expected to provide a reference for the relocation of other regional airports.

The application of urban rail transit station connection guidelines in mountain city pedestrian transfer
Authors: Li Xiao , Leng Haiyang , Tian Kai 
Published: April 2020

Abstract
Rail transit takes the advantage of large volume and fast speed as the first choice for many people to travel, and the way of pedestrian transfer is the preferred way for residents of mountainous cities. Compared with plain cities, the sharing rate of pedestrian transfer in mountainous cities is higher. However, due to the large vertical elevation difference in most mountainous cities and the urban characteristics of group development, there are problems of poor connectivity of pedestrian network, inadequate interchange crossing facilities and large bypass distance in the pedestrian transfer in mountainous cities, which causes potential safety hazards and inadequate convenience for pedestrians to travel. By redefining the actual transfer distance and the planning and design scope, this paper analyses the pedestrian transfer characteristics of mountainous cities from a psychological point of view. Taking Chongqing as a typical mountainous city as an example, based on the newly issued Guidelines for Connecting Rail Transit in Chongqing, the application of the Guidelines in actual projects is analysed to prove the generalization of the Guidelines.

Authors: Luo Gangqiang , Wang Qin 
Published: April 2020

Abstract
Based on the basic assumptions of the developers and the buyers in the housing market, this paper introduced the profit function of typical developers and the utility function of typical buyers as building the equilibrium price model of housing, and constructed the decision model between the basic value of housing, the bubbles of housing price and the degree of housing price bubbles. The absolute scale and relative scale of housing price bubbles in 35 large and medium-sized cities were calculated based on the above models. A comparative analysis was conducted on the bubble level of housing prices in 35 large and medium-sized cities in China from 2010 to 2018. Results indicated that the bubbles had an increasing trend in recent years, but there were obvious differences between cities. Housing market regulation policy should take account of the differences between cities.

Published: April 2020

Abstract
Urban communities, as the most basic unit of the human systems on Earth, are important areas for mitigation and adaptation actions in climate change. However, with a lack of deep understanding of the status quo and composition of community carbon emissions, as well as of the issues in low-carbon actions, the measures taken are often superficial and not targeted, which makes low-carbon activities difficult to implement. This study selected different types of communities for questionnaire surveys online, and conducted field interviews and in-depth surveys afterwards in typical communities. Key data such as community energy consumption, transportation, garbage disposal, and the status of community low-carbon actions were collected, based on which the potentials of carbon reduction were analysed, the obstacles in low-carbon community construction were discussed and corresponding countermeasures were proposed.

The evaluation of fatigue strength based on characteristic length
Authors: Hou S Q , Gao X G 
Published: April 2020

Abstract
Different approaches are used to evaluate fatigue behaviors according to the geometric shape and size of defects in material, though it is well known that the fatigue properties of a material are intrinsic, and should be independent of geometric shape and size. By introducing the concept of fatigue characteristic length, the failure of material occurs when equivalent stress amplitude within characteristic length reach to fatigue strength of smooth material. Using this method, fatigue behaviours of material, no matter with or without stress concentration or singularities, can be evaluated in the same way. It also can explain the “size effect” of small defects on fatigue problem. Considering the fatigue failure of material within characteristic length, the evaluation of fatigue strength for problems with stress concentration or singularity has been studied by experiment.

Authors: Huang Chen , Bai Yu , Lu Linlin 
Published: April 2020

Abstract
The occurrence of the Tianjin 8.12 accident indicates that it may lead to extremely serious production safety accidents once the risk of port operations for dangerous goods container is out of control. It could cause huge loss to personnel, property and social security, and difficulty in emergency handling of accidents. For the hazard analysis and quantitative risk assessment of port operation for dangerous goods container, this study proposes a risk assessment method that combines analytic hierarchy process (AHP) and fuzzy comprehensive evaluation (FCE). Firstly, statistically analyze relevant accident cases in China in recent years, and use the fishbone diagram method to establish a system of multi-level and multi-dimensional risk assessment. Secondly, the AHP is used to assign the weight of the evaluation indicator system. Finally, the FCE method is raised to establish the fuzzy mapping relationship. The evaluation vector calculated by the fuzzy matrix and the weight vector is used to achieve the quantitative assessment conclusion. The method is validated by an instance application of dangerous goods containers port operation of a company.

Published: April 2020

Abstract
In the field of territory spatial planning, transportation accessibility is an important index to measure regional transportation networks. It represents how easy it is for regions to communicate with each other. As a new area of Shanghai Pilot Free Trade Zone, Lin-Gang special area will carry a huge trade market. Therefore, high demands have been put forward on both passengers and freight transport in this region. Based on GIS spatial analysis technology, this paper analyses two types of factors affecting traffic accessibility in the Lin-Gang special area. The first type is road attributes, like road length, road area, road density and road accessibility index. The second type is the spatial pattern of construction land. The results show that the transportation network in Lin-Gang special area is extremely developed, especially the southern area of Pudong International Airport, where the proportion of highway is more than half. The transportation accessibility time to Lin-Gang special area is less than two hours all over Shanghai.

Authors: Liang Xingcan 
Published: April 2020

Abstract
In China, although road traffic safety has improved in recent years, the number of deaths caused by traffic accidents is still at a high level every year. Accidents due to drivers’ dangerous driving behavior account for a large proportion. This study designed and implemented a highway naturalistic driving experiment. The driving performance data and the observer record data obtained in the experiment were used to extract four dangerous driving behaviors: rapid acceleration, rapid deceleration, sudden steering and drowsy driving. The correlation between the three kinds of urgent behaviors and driving fatigue was analyzed qualitatively and quantitatively. Finally, the correlation model between the frequency of urgent behaviors and drowsy driving was built using Naive Bayes. The feasibility of using this method to identify drowsy driving behavior was discussed.

Published: April 2020

Abstract
The immobility of real estate products and the regional nature of the consumption of real estate products make the real estate industry have obvious regional characteristics. The current policy adjustments in the real estate market emphasize differentiation, that is, the regulation methods of each city are becoming more and more different, not only because of the policy of the city, but also the policy of the district. For exploring the basis of differential regulation, the article takes Sichuan Province of China as an example. Through the selection of four first-level indicators and thirteen secondary indicators, 21 cities (districts) are divided into four types of areas. Then the entropy method is used to obtain the factors that affect the housing prices in each category. Based on these, it is suggested to improve the real estate market related policies from the three aspects: promoting the construction of the housing rental market, guiding the rational expectations of buyers and correctly guiding the flow of people.
