Motivating small-displacement car purchasing in China

Due to the rapid development of the automobile industry and the ever-increasing quantities of produced and sold automobiles in China, many problems such as fuel scarcity and air pollution have emerged. To alleviate such problems, one solution is to promote households to purchase small-displacement (engine) cars (SDCs). Based on the theory of planned behavior, we develop a theoretical framework to examine how influencing factors such as environmental attitude, subjective norm, self-image and environmental knowledge motivate SDC purchasing behavior through SDC purchasing intention in China. We further extend the research framework to examine whether the factor of economic incentives moderates the relationships between SDC purchasing intention and behaviors. Using an empirical study with 232 usable questionnaire responses, we observe that SDC purchasing intention partly mediates the relationship between three of four influencing factors (environmental attitude, self-image, environmental knowledge) and SDC purchasing behavior. Statistical results also show that the factor of economic incentives moderates the relationship between SDC purchasing intention and behavior. Our results indicate that three of four influencing factors can yield SDC purchasing behavior, especially when SDC purchasing intention exists. Economic incentives such as financial support from the government could promote SDC purchasing intention to transform into purchasing behavior.     

Techniques for the inference of mileage rates from MOT data

Abstract

Mathematical and computational techniques are developed for the processing and analysis of annual Ministry of Transport roadworthiness (MOT) test data that the UK Department for Transport has placed in the public domain. First, techniques are given that clean erroneous records and a linking procedure is provided that permits the inference of an individual vehicle's mileage between consecutive tests. Methods are then developed that analyse aggregate mileage totals, as a function of vehicle age, class and geography. The inference of aggregate mileage rates as a function of time is then considered.

基于浮动车技术的北京西三环快速路交通运行状况分析

以北京西三环（玉泉营桥—四通桥）快速路为研究对象,基于调查研究得到瓶颈点分布,采用浮动车技术得到不同路段行程速度作为评价指标的统计数据,定量论证和分析瓶颈点的存在对北京西三环交通运行的影响程度,可为城市交通管理部门采取相应的改善和疏堵措施提供理论和数据支撑,同时,也能为其他城市快速路的交通运行状况研究提供—定的参考与借鉴.     

选择铁路方式出行的阻碍因素综述

研究表明,即使铁路出行是最具有成本效益的出行方式,许多出行者仍然会选择其他出行方式。这表明选择铁路出行方式存在一些与费用无关的阻碍因素。本文对有关这些阻碍因素重要性的文献进行了综述,这些研究主要来自英国,但也有一部分来自于其他国家。共确认了37种不同的阻碍因素,它们可以被划分为＂刚性因素＂、＂柔性因素＂与＂互补性因素＂。出行者通常不会只考虑其中的单一阻碍因素,而是将这些阻碍因素看成一个整体,由此使得对最重要阻碍因素的确认十分困难。很多情况下,对于某一出行者来说,所有存在的阻碍因素都需要在出行方式转移之前解决。在思考不同阻碍因素的相对重要性后,对克服它们并实现其他出行方式向铁路转移的最有效措施提出了建议。这涉及主要的交通政策,因为它能够为有限的可利用资金确定目标市场,从而影响出行行为并提高出行方式的可持续性。
