基于因子分析的高职学生口语交际能力量化评估研究

采取因子分析法,可以对高职学生口语交际能力进行量化评估.具体评价步骤包括:设计十一个评价指标,运用统计软件SPSS对数据进行因子分析.通过因子分析,把高职学生的口语交际能力主要分为三个主因子,分别是言辞得体水平(F1),腔调得体水平(F2),体态得体水平(F3),最后设计了高职学生口语交际能力量化评估表.     

城市轨道交通短时客流预测体系框架及关键技术

针对当前城市轨道交通短时客流预测系统性不强等问题,构建短时客流预测体系框架,并讨论预测过程涉及的关键技术。框架的构建以自动售检票系统（AFC）获得的数据为出发点,统计站点客流和线网客流OD矩阵两类基础客流数据;在此基础上,构建线网客流分配模型,结合视频数据、站点平面布置和列车运行时刻表三类数据,考虑乘客步行时间的影响,估计断面客流数据;接着,在分析站点客流和断面客流数据时空特性的基础上,分别预测站点和断面短时客流;利用站点客流和断面客流短时预测结果反推未来OD矩阵;同时引入GARCH模型分析预测结果的可靠性,以提高短时客流预测结果的可信度。

高速公路路面状态对交通安全的影响评价

选取路面损坏状况指数和路面抗滑性能指数作为路面状态的表征指标,速度标准差系数作为交通流表征指标间接反映交通安全状态。在考虑交通量影响的情况下,仿真模拟实际路段沿线交通流速度标准差系数的变化情况,结合已有的路面检测数据,建立高速公路路面状态对交通安全的影响评价模型,并提出了影响分级标准。基于提出的模型,开发了一套评价软件,以沪宁高速公路为应用实例进行分析。结果表明：本文所构建的关系模型可准确评价高速公路路面状态对交通安全的影响。

Design and evaluation of a grade-separated intersection: a case study of the proposed Belgrade ‘Hipodrom’

This paper presents the evaluation results of three traffic solutions for the complex grade-separated intersection located in the old part of Belgrade at the junction with the new bridge over the Sava River. The corridor to which the intersection belongs together with the new river bridge are parts of a great urban artery called the Inner Half Semi-Ring Road (IHSRR). The traffic solutions that are evaluated are defined in the preliminary design phase, based on two opposed concepts: a complete grade separation of all intersection legs (the CPV alternative – ‘grade-separated’) and a grade separation designed to minimise construction costs (DMC 1 and 2 alternatives – ‘minimise cost’). The evaluation procedure is conducted in three steps: first, the score based on expert assessment of the functionality of the design solutions is determined; second, the alternatives are ranked according to the value of a set of state indicators obtained by micro-simulation using PTV–VISSIM 4.10; and third, the final score is obtained by multi-criteria evaluation using the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) method. The results of the first evaluation step show a small advantage for DMC 2, a sub-alternative of the DMC 1 alternative. The results of the micro-simulation give advantage to the DMC 1 alternative. The multi-criteria evaluation provides a better ‘goodness factor’ for the CPV alternative against the DMC 1 alternative. At the same time, the least construction cost favours alternative DMC 1.     

Evaluating Flexible Transport Solutions

Abstract

Flexible transport services (FTS) have been of increasing interest in developing countries as a bridge between the use of personal car travel and fixed route transit services. This paper reports on findings from a recent study in Queensland Australia, which identified lessons from an international review and implications for Australia. Potential strategic directions, including a vision, mission, key result areas, strategies, and identified means of measuring performance are described. Evaluation criteria for assessing flexible transport proposals were developed, and approaches to identifying and assessing needs and demands outlined. The use of emerging technologies is also a key element of successful flexible transport services.
