建筑排水系统内部的水流运动与室内环境关系的研究

研究目的:研究建筑排水系统内部水流和气流的运动规律,提出解决排水系统气体内溢的方法和措施。研究方法:结合对单一横支管排水,立管上端通大气,下端经排水横管排入直通大气的检查井的排水系统为实验室研究模型,分析建筑内部水流与气流运动引起的压力变化。研究结果:建筑排水系统内水流、气流的复杂运动会引起系统内压力的变化,而压力变化是引发排水系统气体内溢的关键。研究结论:建筑排水系统内水流和气流的运动,会引起排水系统内部压力的变化,而压力的变化是引起水封破坏,有害气体进入排水系统内部的根本原因。设置专用通气立管排水系统、排水管道的合理布置和敷设、选择高质量的卫生器具、合理采用排水管材和保证排水管道的施工质量、科学地使用排水系统,是解决居住建筑排水系统气体内溢的有效措施。

User satisfaction with battery electric vehicles in South Korea

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.     

城市居住区交通稳静化措施研究

本文重点探讨城市居住区交通稳静化措施,对4个机、非机混行居住区217人按拥有机动车和非拥有机动车划分两组进行交通稳静化措施调查,并进行稳静化措施速度试验。结果表明：被调查人群对减速带、减速垫、路中间隔离岛、波纹型道路、路段宽度缩减五项稳静化措施意见倾向性不同;稳静化措施对机动车有明显降速作用,对自行车车流亦起减速作用,使人行系统更加安全。     

既有居住区交通改造评价指标体系研究

既有居住区交通改造评价指标体系的建立旨在了解老、旧小区各项交通设施现状,对改造必要性等进行评价。其构建的指标体系包括4个一级指标,12个二级指标及34个评分细则,其中一、二级指标的权重分别用层次分析法和组合赋权法来确定,评分则是采用专家打分与居民意愿调查相结合。该体系提倡因地制宜,对于不同地域、区位的小区参考规范也不尽相同,力求使结果更科学、合理。     

Hybrid cyclicity: Combining the benefits of cyclic and non-cyclic timetables

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.
