大型货运车辆生态驾驶及节油潜力评估

改善驾驶行为、推广生态驾驶是未来降低机动车辆燃油消耗和污染排放的重要潜在方式.分析由车辆远程在线监控技术(OBD)获取的199辆大型货车在观测的4 d内的位置、速度、油耗等微观运行状态的逐秒数据，提出判定急加速、过急加速、急减速、过急减速和超长怠速等5种不良驾驶行为的统计方法，并建立面板数据固定效应回归模型分析5种不良驾驶行为对大型货车油耗的影响，进而定量评估改善不良驾驶行为的节油潜力.研究结果表明，超长怠速和过急减速行为会显著增加大型货车的油耗，减少超长怠速时间和过急减速行为的节油潜力分别可达2.6%和3.8%.     

Cruise Traffic Seasonality Patterns in the Western Mediterranean and the Adriatic Sea: A Challenge to Port Operators

The positive trend in the cruise industry since the beginning of the twenty-first century brings with it a series of challenges, mainly for cruise lines and ports. Among them is the seasonality of cruise traffic. This study examines the seasonality of the cruise traffic in the Western Mediterranean and the Adriatic Sea. A sample of 26 ports in 7 countries forms the basis of the empirical analysis, which uses the monthly total cruise passenger movements of each port during the period from 2005 to 2015 as a variable. Methodologically, a “dynamic” classification of ports structured in three sizes is proposed, the seasonality pattern of each port is determined, a cluster analysis is applied to group the ports in clusters with homogeneous patterns, and the changes in seasonal concentration during the analysis period are determined using a Gini coefficient. The main findings suggest the heterogeneity of the ports in the analyzed area and the existence of two clusters with different seasonality patterns. Furthermore, a list of strategies is provided to address the negative effects of cruise traffic seasonality in the management of cruise terminals, taking into account that each cluster obtained requires different strategies.     

Revisiting urban hierarchy and specialization from a maritime perspective

ABSTRACT

Port–city relationships have attracted paramount attention from a variety of scientific disciplines for several decades, such as geography, history, planning, regional science, sociology, and economics to name but a few. Yet, the extent to which maritime traffic specialization obeys the same spatial distribution than other economic activities remains underexplored today. This article tackles these lacunae head-on by proposing an empirical analysis of the way vessel tonnage per main categories of flows (e.g. containers, bulks, passengers) coincides with the demographic size of the world’s coastal and inland city-regions, using novel data on global inter-port vessel movements and harmonized population data over the period 1977–2008. Our main results confirm that such traffic is far from being randomly distributed, as its volume, value, and diversity concentrate at the top of the urban hierarchy. This research motivates the need to further integrate physical connectivity into the study of cities and their development mechanisms.     

Calculation of the freight revenues in Turkey-focused maritime transportation

The Central Bank of the Turkish Republic (TCMB) in Turkey has announced the data of freight revenues. The data that have been announced depends on the information obtained from the port customs and compiled by the Turkish Statistical Institute (TUIK). Because of the distinctive structure of the freight market, certain requisite generalizations and projections are used for data calculation. Accordingly, calculations that depend on generalizations and predictions are likely to weaken the effectiveness of the decisions already made or going to be made. The aim of this study is to calculate more realistically the real freight revenues of ships that have carried out loading or discharging operations in Turkish ports. In accordance with this purpose, the volume of freight revenues and their distribution between Turkish and foreign flagged ships is calculated. A Microsoft SQL-based algorithm is developed in order to do the calculation. Within the scope of the study, the total fright revenue of Turkey-oriented shipping industry is calculated to be USD 5.8 billion. Proportionately, 79.53% of the revenue belongs to foreign flagged ships, 12.70% of it belongs to foreign flagged ships with Turkish owners, and only 7.78% of it belongs to Turkish flagged ships.     

道路超限运输治理中的合谋行为理论研究

对超限超载货物运输治理理论的研究是长效治理超限超载的基础工作。首先运用经济学的逻辑方法,从道路的公共性、超限超载的外部性、超限超载的经济动力及机制等角度对我国公路超限超载问题做出了经济学解释;随后,运用博弈论的理论和方法,对超限超载运输治理中道路监管部门与运输企业之间的合谋问题进行分析,试图建立运输企业、道路监管部门和政府的博弈模型,并通过这一模型分析运输企业与道路监管部门之间的合谋行为;最后,通过"政府—监管部门—运输企业"三者之间的博弈模型,探讨建立预防道路监管部门与运输企业之间形成合谋的内在机制。以期从理论上系统认识这一问题,为构建长效治理机制提供理论依据。
