旅游资源互补性研究

目前对长江三峡旅游资源的研究一般集中在旅游资源的独特性、可开发性等方面,本文试从旅游资源的互补性着手,对区域性旅游资源进行共享多贏方面的进行基础性探索,为跨区域旅游资源的开发利用提供思路。     

四川旅游资源交通系统综合布局分析

作为影响旅游活动的重要因素之一,交通布局直接关系到旅游业的发展。本文根据四川旅游资源的现状、地理位置等情况,将四川划分出三大旅游经济圈,从各旅游经济圈交通现状及客流特征入手,利用关联分析的方法,结合数据对比,剖析了各旅游经济圈与交通的关联。最后,在整合四川旅游资源的前提下,得出了四川旅游资源交通系统综合布局的相关结论。     

旅游交通融合发展研究——以福建省为例

为深入落实"交通强国"战略和实现"全域旅游"目标,推动旅游与交通深度融合发展,需做好旅游交通体系发展的顶层设计。通过分析旅游交通面临的问题,提出了旅游交通融合发展的理念。将福建省作为案例,针对福建旅游交通网络面临的问题,提出了"快旅慢游"旅游交通体系的建设目标、实施方案及保障措施。依托高铁、民航、邮轮和公路等综合立体交通网络,提出了"一带三环多放射"旅游交通"快旅"通道的发展思路;通过特色旅游产品开发、旅游服务质量提升等方面,规划了"慢游"微循环旅游交通的发展方案,构建了福建省多层次、综合立体的旅游交通体系发展新格局。以期通过福建省旅游交通融合发展案例研究,为其他省市旅游交通融合发展借鉴参考。

旅游和公务运输通道公铁竞争研究

为了研究旅游和公务型运输通道内客流特征及公铁竞争力,对云南省昆明到大理、丽江和曲靖三个运输通道开展问卷调查,得到旅游型通道中,旅游客流主要由铁路承担,旅客对出行安全性、舒适性、经济性要求较高,而对时间要求不高,旅客出行需求多样化;公务型通道中,公务客流主要由城际铁路承担,公务旅客对时间较为敏感,对出行快捷性、经济性要求较高,需求相对单一.通过选取合适的指标,运用主成份分析法,对两种类型通道中公路和铁路的竞争力进行综合评价,得到目前昆明到大理和丽江旅游型通道中普通铁路提供的服务满足不了旅客的需求;昆明到曲靖公务型通道中,铁路运输竞争力强于公路运输.     

Effect of land use on decisions of shopping tour generation: A case study of three traditional neighborhoods in WA

This study investigates the relationship between land use and shopping tour generation using an activity-based shopping model that captures the effects of land use patterns on household decisions of shopping tour frequency, tour scheduling and mode choice. The model was calibrated using travel data collected in three traditional neighborhoods located in the Puget Sound region, WA, and shopping travel patterns across seven common household structures were analyzed. The results reveal that land use patterns have virtually no impact on overall shopping tour frequency. However, land use does seem to be associated with decisions about the type of shopping tours undertaken. For example, households with poorer accessibility tend to make fewer one-stop shopping tours, and are more likely to combine shoppingtrips with other trips to form multi-stop shopping tours as a means of compensating for locational deficiencies. Finally, we also found that traditional neighborhood residents who live closer to the neighborhood commercial street, and thus, have greater accessibility, are more inclined to use non-auto modes for one-stop shopping tours.     

基于线阵CCD相机的轨道图像采集系统设计

轨道图像信息的采集是对轨道状态实时监控的重要手段。设计了一种基于线阵CCD相机的新型图像采集系统,该系统利用线阵CCD相机连续快速的记录轨道信息,整个系统运行速度能达到10 km/h,钢轨表面图像的横纵分辨率为0.5 mm×0.5 mm,并且图像不失真,不漏采;同时解决了信号触发和里程记录等关键问题,实现轨道信息的完整采集。实验结果表明:系统不受小车速度变化的影响,并能准确记录里程信息,从而为后续缺陷的检测与定位奠定基础。

Analysis of plug-in hybrid electric vehicles’ utility factors using GPS-based longitudinal travel data

The benefit of using a PHEV comes from its ability to substitute gasoline with electricity in operation. Defined as the proportion of distance traveled in the electric mode, the utility factor (UF) depends mostly on the battery capacity, but also on many other factors, such as travel pattern and recharging pattern. Conventionally, the UFs are calculated based on the daily vehicle miles traveled (DVMT) by assuming motorists leave home in the morning with a full battery, and no charge occurs before returning home in the evening. Such an assumption, however, ignores the impact of the heterogeneity in both travel and charging behavior, such as going back home more than once in a day, the impact of available charging time, and the price of gasoline and electricity. Moreover, the conventional UFs are based on the National Household Travel Survey (NHTS) data, which are one-day travel data of each sample vehicle. A motorist’s daily travel distance variation is ignored. This paper employs the GPS-based longitudinal travel data (covering 3–18 months) collected from 403 vehicles in the Seattle metropolitan area to investigate how such travel and charging behavior affects UFs. To do this, for each vehicle, we organized trips to a series of home and work related tours. The UFs based on the DVMT are found close to those based on home-to-home tours. On the other hand, it is seen that the workplace charge opportunities significantly increase UFs if the CD range is no more than 40 miles.
