基于设施属性的城市轨道交通融资模式

以项目区分理论为理论基础,从轨道交通的基本属性入手,按照可经营性和可拆分性对轨道交通基本设施进行分类,对不同属性的设施进行组合.按照所有权和经营权是否转移,将各种适用于轨道交通的融资方式进行分类;并将两者进行匹配,提出了符合轨道交通客观发展规律、可供轨道交通建设发展采用的多元化融资模式及其评价方法.     

城市公共交通多元票制初探

借鉴国外先进经验,引进多元化公交票制是国内推进公交优先发展的重要措施.多元票制,即将乘客进行科学的分类,根据乘客的出行需求,设置不同种类的车票,以提高公交吸引力.就国内公交发展现状来看,换乘优惠的票制改革是推广多元票制的最佳切入点.     

城市公交车身轻量化分析与设计

作为城市枢纽的公交车,采用纯电动技术可作为降低城市环境污染、减少能源消耗的切入点。目前续驶里程短是制约纯电动公交发展的主要因素。可以通过增加动力电池的电量或者对整车进行轻量化来增加续驶里程。在轻量化设计方面,对高强钢、铝合金、镁合金、工程塑料和碳纤维等几种轻量化材料进行对比分析,从中选出目前较为合适的铝合金材料。通过理论计算与设计,再通过有限元分析手段进行验证,设计出合理的车身骨架用型材截面以及连接结构。实现减重的同时保证车身结构可靠性,同时通过全生命周期中成本评估对比,发现铝合金车身可以实现降本。

The design of a terminal for dangerous goods

This paper aims at examining the possibility of setting up a model terminal for the transportation of dangerous goods. It should be designed in such a manner that its use would be possible for any kind of transportation.

This consideration has been prompted by the interface between transportation planning and technology, as well as by the tendency for harmonizing international recommendations pertaining to the transportation and handling of dangerous goods, especially during the last decades where unified transport has gained ground due to the advantages provided for the safe consignment of dangerous cargoes.

Since the large increase in terminal productivity is due to the heavy investments that were effected in terminal installations and to the modernization of the administration‐management of terminals, a mathematical simulation has been adopted to assist the determination of the capacity of a terminal for dangerous goods.

It is evident that different criteria and various assumptions have been taken into account in order to facilitate a deeper analysis, without ignoring the contribution of dangerous goods to the socio‐economic development.

From the outset of the study, it was already clear that the said process will make it possible to present—as a model—a simple but well defined situation for the purpose of drawing useful conclusions.     

城市土地利用对交通需求特性影响研究

针对长期以来关于城市土地利用对交通需求特性影响研究中存在的争论,系统分析了土地利用、社会经济属性和交通需求三者之间的关系。建立多元线性回归模型,分别考察人口密度、土地混合程度、家庭收入和家庭大小对于交通出行次数、交通方式、出行距离和出行时长的影响。通过对回归模型显著性水平的检验,找出真正具有内在联系的因素。最后阐述了土地利用与交通相关研究的意义,指出未来研究方向。
