Battery electric vehicles (BEVs) have been promoted by the government over the last several years, driven by public concern over pollutant emissions from internal combustion engines. However, the conditions related to driving BEVs are not yet satisfactory for many BEV users, as evident from sluggish market growth compared with general market forecasts. Thus, a fundamental aspect of diagnosing the current conditions of BEV operation is to evaluate BEV user satisfaction. This study establishes hypothetical links between potential factors and BEV user satisfaction, and between BEV use satisfaction and intention to repurchase and recommend. The hypothetical links are specified using a partial least squares structural equation model (PLS-SEM) and estimated based on a survey of actual BEV owners (N=160) who had driven BEVs for at least six months. The outcomes of PLS-SEM suggest that seven relations out of nine hypothetical links were statistically significant. In particular, it is noticeable that the intention for cost-saving during operation is a key factor for BEV user satisfaction and that user satisfaction with range and charging has a positive effect on the overall satisfaction of BEV users. Furthermore, those who are satisfied with BEVs have the intention to repurchase and recommend BEVs to others. Because this study was conducted based on actual experience of BEV users, the findings could enhance understanding of the BEV driving environment and, thus, pave the way to provision of better service for BEV users. 相似文献

We propose a new type of timetable that would combine both the regularity of the cyclic timetables and the flexibility of the non-cyclic ones. In order to do so, several combinations of the two timetables are considered. The regularity is incorporated in their design and the flexibility is evaluated using the passenger satisfaction (in monetary units). Each of the tested timetables is constructed using the Passenger Centric Train Timetabling Problem (PCTTP), that is solved using a simulated annealing heuristic. Note that the PCTTP, unlike the traditional Train Timetabling Problem (TTP), does not take into account the conflicts among trains. The aim of the PCTTP is to design such timetables that the passengers’ satisfaction is maximized and it remains the aim of the TTP to remove any potential conflicts. The performance of each of the considered timetables is assessed on the real network of Israeli Railways. The results of the case study show that our proposed hybrid cyclic timetable can provide the benefits of the cyclic and the non-cyclic timetable simultaneously. This timetable consists of 75% of cyclic trains (securing the regularity of the service) and of 25% of non-cyclic trains (deployed as supplementary trains during the peak hours and capturing the demand fluctuation). The level of the passenger satisfaction of the hybrid cyclic timetable is similar to the level of the non-cyclic one, which has about 18.5% of improvement as compared to the purely cyclic one. 相似文献

This paper considers both the access and egress stages as an entire process to analyze the satisfaction levels of commuters with metro commuter journeys. Based on a survey in Nanjing, China, seven intermodal travel groups are employed as targets for this analysis. The groups include Walk–Metro–Walk, Walk–Metro–Bus, Bike–Metro–Walk, Bike–Metro–Bus, Bus–Metro–Walk, Bus–Metro–Bus and Car–Metro–Walk, which are named according to the modes of transportation that are employed for access and egress trips. Binary logit models are developed for each group to identify the main factors of satisfaction level. The results show that access and egress stages serve important but different roles in the seven groups. Facility service qualities in two stages are the primary factors that affect overall satisfaction. The groups with same access or egress modes have significantly different core factors. Access by bike and bike–metro–transit users are concerned with bike parking safety, whereas bike–metro–walk users value parking spaces near metro stations. With two transfers between bus and metro, transit–metro–transit users indicate that the weak point in the access stage is the crowded spaces on buses. However, transit–metro–walk users value bus on-time performance, which is also valued by groups with metro–bus egress transfers. For egress by walking, commuters that use motorized modes for access are concerned with the egress walking environment, whereas users of non-motorized access modes are more concerned with egress walking spaces. The findings of this study are helpful for policy developments than can improve public satisfaction with commutes by urban metro. 相似文献

机场陆侧交通标志对驾驶人及时、准确地寻找目的地至关重要,交通标志设计应充分考虑驾驶人对标志信息的满意度。为此,针对北京大兴国际机场陆侧交通标志,采用均匀设计法提出8组交通标志设计方案,基于叙述性偏好(SP)实验设计调查问卷,在线发放并回收了357份有效问卷,从中获取驾驶人对各组设计方案的满意程度。采用多元多项式回归分析方法,分析陆侧标志文字高度、文字间距、出口方向信息位置、地点信息底色这4种信息要素对于信息满意度的影响,进而采用主观评测法得到各信息要素的权重。采用专家打分法构造判断矩阵,进而运用层次分析法确定各信息要素的权重。将主观测评方法和层次分析法得到的权重结果进行验证比较。结果表明:随着文字高度增加、文字间距变大,地点信息底色与出口方向信息底色对比越明显,驾驶人对于标志的满意度也随之增加;同时,出口方向信息位于左侧时,驾驶人对于标志的满意度更高;基于层次分析法和主观测评法得到的各信息要素权重排序一致,均为:地点信息底色 > 文字高度 > 出口方向信息位置 > 文字间距。该结果可以为机场陆侧交通标志设计提供可靠参考。 相似文献

为提高整个路网的运行效率, 建立了一个非线性规划模型, 进一步得出相应的非线性模糊规划模型, 根据相邻交叉口交通流大小和方向的不同, 通过动态模糊控制手段, 采用弹性信号周期和最大隶属度原则, 合理地动态分配交叉口信号相位。驾驶人通过对路径察觉, 获得最小察觉阻抗路径, 并与智能交通系统提供的各路径阻抗进行对比, 选择最大满意度的路径。分析结果表明: 动态模糊控制和模糊决策法与最短路径法的交通流分配结果基本一致, 模糊最优控制使得信号交叉口的控制效用提高50%以上, 且动态模糊控制和模糊决策法更能反映人的行为, 是一种有效的交通控制方法。 相似文献
