文章根据大连湾老铁山水道的情况,考虑变吃水的运输方式,以船长、船宽、吃水及航速作为变量来进行船型方案的组合。选用净现值、内部收益率、投资回收期、必要运费率和综合经济指标作为衡量船型方案的标准,通过分析计算得出最佳的船型方案,为小型渔货船型选择提供参考。     

公路客运班车报停制度研究

公路客运峰谷现象明显,在运能、运力有限的情况下,如何才能更好地满足客运高峰期(如春运)的交通需求是政府和企业的一项重要课题。现有的政策并没有使有限的客运资源得到最合理的利用,给能源和环境都带来了一定的影响。文章较系统地从企业和政府两个角度论述了建立班车报停制度的必要性和可行性,通过对客运线路的调查,对公路客运班车报停制度的社会经济效益作了定性和定量分析。

Carpooling and carpool clubs: Clarifying concepts and assessing value enhancement possibilities through a Stated Preference web survey in Lisbon, Portugal

The increase of urban traffic congestion calls for studying alternative measures for mobility management, and one of these measures is carpooling. In theory, these systems could lead to great reductions in the use of private vehicles; however, in practice they have obtained limited success for two main reasons: the psychological barriers associated with riding with strangers and poor schedule flexibility. To overcome some of the limitations of the traditional schemes, we proposed studying a carpooling club model with two main new features: establishing a base trust level for carpoolers to find compatible matches for traditional groups and at the same time allowing to search for a ride in an alternative group when the pool member has a trip schedule different from the usual one. A web-based survey was developed for the Lisbon Metropolitan Region (Portugal), including a Stated Preference experiment, to test the concept and confirm previous knowledge on these systems’ determinants. It was found through a binary logit Discrete Choice Model calibration that carpooling is still attached with lower income strata and that saving money is still an important reason for participating in it. The club itself does not show promise introducing more flexibility in these systems; however, it should provide a way for persons to interact and trust each other at least to the level of working colleagues.     

Mobility, social exclusion and well-being: Exploring the links

Building on a growing research foundation, transport policy makers have begun to associate the ability to be mobile with having a role in the facilitation of social inclusion. However, the further connection to well-being is not as well understood. This paper explores the association between a person’s travel patterns, their risk of social exclusion and self-assessed well-being. Key influences on social exclusion are discussed, with trip making emerging as a significant influence. Trip making is not a significant direct influence on well-being but does exercise an indirect influence through the impact on risk of social exclusion. The modelling process enables a value for additional trips to be estimated, the value being about four times the values derived from conventional generated traffic approaches. Similar high values are found in separate metropolitan and regional case studies, confirming the significance of the results.
