高油价时代出租车运价不能一涨了之

自2005年下半年以来，为了消化一路攀升的油价所导致的经营成本剧增，国内各大中城市出租车运价迎来涨声一片，西安、合肥、南京、济南、杭州等城市相继对出租车运价进行了调整。同时，部分省份和城市对相关行政事业性收费进行减免，同时对出租车行业实行油价临时补贴政策或给予燃油补助，以帮助出租车行业渡过难关。2006年4月17日，上海组织召开“建立上海出租汽车运价油价联动机制听证会”，拟调整起步价和单价；4月26日，北京市发展和改革委员会举行北京市出租汽车租价调整听证会，拟提高租价标准，

在民国打车要花多少钱?

正七十年前的三张调价公告1946年4月1日,上海市政府公用局贴出布告如下:"查本市出租汽车收费标准,兹经本局参酌油价增涨情形重予调整,每差二十分钟计收费二千四百元,逾时每五分钟加六百元,自即日起实行,除饬知出租汽车业同业公会一律依照规定收费,如有浮收情事,定予严惩外,合亟布告周知。"4月1日是愚人节,但这张布告并非愚人节的笑话,它向我们传递出了两条信息:第一,抗战胜利后,通货膨胀速度加快,油价涨得厉害,故此政府上调出租车收费标准,并     

高速公路货车计重收费调整为车型收费定价标准研究——以四川省为例

本文首先对国内外高速公路收费定价方法进行了系统的梳理。以四川省高速公路为具体研究对象,在总结四川省货车收费现状的基础上,提出货车计重收费切换至车型收费的总体要求与基本原则,并对相应定价标准问题展开研究。研究提出了客货同价、统一费率、平衡点三种不同的货车收费定价方法,结合四川省2018年实际收费数据对三种方法分别进行测算,并对三种方案进/车·公里,收费系数1∶2∶3∶4∶5∶6的平衡30%,其中,1类、5类及6类货车通行费收入增加,2类、3类、4类货车通行费收入5下0降亿。根据这一结果,最后提出货车计重收费调整为车型收费的实施建议。

Analysis of factors affecting the choice of route of pedestrians

Pedestrians as compared to vehicular traffic enjoy a high degree freedom of movement even in heavily congested areas. Consequently, there are more alternative links available to pedestrians between a given origin‐destination (O‐D) pair. This paper describes a study done by the University of Calgary to evaluate the factors affecting the choice of route on intra‐CBD trips or trips within the Central Business District (CBD).

An origin destination survey conducted in downtown Calgary, Alberta enabled the identification of the most significant factors influencing the choice. These factors were analyzed in relation to the physical characteristics of the location, personal characteristics of the trip maker and the type of the trip.

It appears that most people chose the shortest link and factors such as the level of congestion, safety or visual attractions were only secondary. This suggests that the length should be made a major consideration when planning and designing pedestrian links.     

输油管道中原油乳状液的流变性研究

原油乳状液的流变性是原油开采后在管道中输送的重要研究方面,为了更好地研究这一性质,采用电动搅拌机、偏光显微镜以及流变仪等仪器来测定不同含水率的原油乳状液在不同条件下的黏度,观测不同含水率的原油乳状液在偏光显微镜下的形态。并且分别对原油乳状液的黏度与含水率之间的关系以及与剪切速率之间的关系进行研究,初步确定了所测区块原油乳状液的转相点以及该区块原油乳状液的流变特性,为生产中的油气集输提供了理论依据。     

Preliminary results of an analysis of areas of influence in Shanghai

The main deficiency of most current modeling approaches to transportation can be identified as neglect of the integration of existing geographical knowledge in regard to the ex ante transport/land use modeling approaches, with its focus on territorial dynamics and theory development. This paper addresses this aspect of the problem by introducing a theoretical and methodological framework for the analysis of the interrelationship between land uses. The analysis attempts to determine to what extent the functional land use in a city can be considered an ordered pattern. The order sought does not rely on purely spatial configurations, but on the correlation of transportation and land use. The first section of this paper focuses on theoretical considerations. It stresses the fact that conventional approaches do not apply in the present context. It then suggests an alternative based on areas of influence and measured in terms of level of attractance of land uses. The second describes a procedure based on this alternative following the remarkable contribution of Hanjoul, Beguin and Thill. An application of this procedure to the analysis of Shanghai is then examined. Finally, an evaluation of the strategies for optimizing the interrelationship between land uses is presented. The paper concludes with a possible research agenda.

Direct analysis of the perceived importance of attributes of reliability of travel modes in urban travel

Reliability of travel modes was found to be the most important characteristic of transportation systems in several attitudinal investigations of individual travel behavior. This paper represents the first part of a research effort aimed at gaining a better understanding of the characteristics of reliability of transportation modes in urban travel. In this research, reliability characteristics are identified; their importance relative to each other is assessed, and an insight into possible structure of an objective reliability index is discussed. The research is based on perceived values of reliability, which were identified through a large attitudinal survey conducted in the Chicago metropolitan area.

Non-parametric analyses of efficiency of airports

This paper estimates the efficiencies and productivity changes of 12 international airports in the Asia-Pacific region based on data from 1998 to 2006. We apply stochastic frontier analysis (SFA) to compute efficiency estimates and use the Malmquist productivity index (MPI) to analyze productivity changes. We use the SFA model with a translog-type production function after testing the statistical hypotheses. According to the results of the SFA hypothesis tests, airports have experienced a technological regression; the deviations from the efficiency frontier are caused more by technical inefficiency than random noise. However, the inefficiency was found to decrease. The MPI reveals a declining trend resulting more from technological change than from efficiency change, with a decrease in inefficiency. Taken together, both the hypothesis tests and the MPI not only provide consistent conclusions, but also suggest that airports should concentrate on technological progress.
