Abstract: Container terminals are the hubs that connect seas and lands in international transportation. In the globalization context of trade, the pursuit of efficient terminal operation is the goal of container terminals, transportation companies, and local governments. As a connecting transportation tool for terminal loading and unloading operations, horizontal transport, and storage operations, the operation of container trucks is optimized on the basis of a coordinated scheduling strategy with terminal working machinery in order to be in line with the concept of high-efficiency operation. Thus, the shortest operating time of ships is taken as the goal, and then the variables of the docking position of the ship and the number of quay crane operations are considered, a model for the three major processes of ship docking is developed, including the docking of ships and the number of quayside operations by arranging storage, transportation, and quay cranes and container trucks in the backyard. Subsequently, an evolutionary algorithm in Excel solver is used for the calculation of the examples, and the effectiveness of stack scheduling in optimizing terminal operation is finally confirmed on the basis of the cooperative scheduling strategy. According to the analysis results, 23.43% of the operation time can be saved under the loading and unloading coordinated container operation.

Abstract: Street parking fees are common in many cities across the world. Knowledge on how such fees impact parking demand is crucial for designing charging schemes. Empirical studies of parking fees are however scares and often hampered by a lack of data systematically collected before and after policy changes. Moreover, almost all studies analyzing the impact of fees on parking demand focuses on dense city centers. This paper aims as showing how on-street parking count conducted before and after the introduction of parking fees of in the suburbs of Stockholm impact parking demand. This paper analyses data conducted before and after the implementation of the new parking policy in 2017, where on-street parking fees were introduced for the first time in the inner suburbs. At the same time, the amount of the fee was also increased in the inner city. Moreover, the fine was raised for the parking ticket issued to cars parked in breach of parking regulations. We find a 35-40 percent reduction in the number of parked cars in response to the introduction of parking fees in the suburbs. However, the increase in the parking fees in the inner city had a substantially lower effect or no effect at all on demand. The effect of increasing the amount of the fine had no impact on the number of the cars violating parking restrictions.

Abstract: Under the situation of integrated development of the Yangtze River Delta, the city of Haining has put forward the strategic goal of "integrating itself into Hangzhou and Shanghai". Therefore, Hang-Hai Intercity Railway has been planned and built as a positive response and specific implementation to this goal. This paper studies the inclusive design in the Hang-Hai Intercity Railway. Through this small practical case, this paper attempts to reflect the current situation of inclusive design in China, especially in public transport. At the same time, it gives high light on the potential advantages of inclusive design in public transport, and provides suggestions for inclusive public transport design, inclusive city construction and inclusive urban agglomeration planning and construction. The research, based on the classification of the railway leading users, analyzes the questionnaires to the railway potential users, together with the design empathy experience of the student teams, further demonstrates the necessity and the possibility of inclusive design applying in Hang-Hai Intercity Railway. Through the practice of the inclusive icon design of each station of the Hang-Hai Intercity Railway, this paper also demonstrates the feasibility of inclusive design in Intercity Rail Transit, and provides inspiration and innovation to optimize and utilize the inclusive design in public transport.

Abstract: Transportation agencies face the challenging task to maintain, preserve and improve infrastructure condition while with limited funding. Pavements are one of the major assets of roadway systems and pavement management system (PMS) are broadly accepted and implemented by agencies and organizations to maintain pavement structures at a high level of service. PMS is a set of tools to support the decision-making process for determining the demand of maintenance, prioritizing projects and optimizing funding allocation. Pavement condition monitoring may be evaluated or assessed by means of various indicators. Performance indicators are an essential part in a PMS, individual performance indicators (IPIs) and combined performance indicators (CPIs) are proposed to monitor and report pavement conditions. IPIs characterize the general condition of the various types of pavement distress which can be related to road performance. The CPI for each road type can be developed or calculated from IPIs. Focus on network level analysis of road pavements, the objective of this paper is to review and compare the development and application of performance indicators for assessment of pavement condition of different country’s guidelines. The utilization and integration mechanism of individual indicator are described and compared among selected country guidelines. The prospective indicators and techniques for future application are further discussed. It can be conclude from this study that the majority studied guidelines have placed great emphasis on surface distress and roughness for pavement condition assessment; international roughness index (IRI) is the most commonly used parameter for evaluation of road roughness due to its objectivity while the determination of surface distress is more subjective. The integration methods from IPIs into CPIs can be summarized as “deduct system method”, “sum system method”, “weighted sum method” and “equation method”.

Abstract: China has preliminarily built a modern high-speed railway network, and the huge scale of the network has put forward higher requirements on infrastructure maintenance and management. In order to achieve high quality and efficient development of high-speed railway, this paper conducts research on the maintenance and management model of China's high-speed railway infrastructure. This article describes the characteristics of infrastructure maintenance management in developed countries of high-speed railways such as Japan, France and Germany; summarizes the technical characteristics of China's high-speed railways and analyzes the factors influencing infrastructure maintenance management in China. Based on the theory of organizational structure, the article systematically analyzes the differences in the work content, work methods, and means of high-speed railway infrastructure inspection and monitoring, routine maintenance, and specialized repair operations, so as to put forward the maintenance management mode of the separation of "inspection, maintenance, repair". This model mixes together the specialization of technical management and the comprehensive integration of production organization. On this basis, a comprehensive maintenance system for high-speed railway infrastructure was designed and a comprehensive maintenance organizational structure and working mechanism was proposed. Practice has shown that a comprehensive maintenance system for high-speed railway infrastructure is conducive to improving emergency response capabilities, reducing operating costs and achieving optimal resource allocation.
