针对枢纽内交通方式运能协调问题,分析运能协调的影响因素,以及运能匹配度分级的标准,建立考虑运能匹配度约束的协调优化模型,并通过Lingo软件进行求解,为枢纽交通方式运能匹配、协调调度提供理论依据。

区域轨道交通综合客运枢纽运能协调优化模型

区域轨道交通综合客运枢纽汇集了铁路、城市轨道交通、城市公交和出租车等多种交通方式,各类交通系统相互配合,实现枢纽的客流集散功能.但其集散能力在客流高峰期易出现瓶颈,需要进一步协调运力资源.文中考虑提高运能协调度、降低运营成本的双重目标,构建运能协调匹配的多目标优化模型,提出应用功效系数法对多目标问题转化为单目标问题进行.并以成都东站为例,通过运用考虑运营成本约束的多目标运能协调优化模型降低运营成本46.52%.

A Method to Measure Eye-Hand Coordination for Extracting Skilled Elements-Simultaneous Measurement of Eye-Gaze and Hand Location-

The purpose of this study was to construct bases for exploring the process of skill acquisition from the viewpoint of eye-hand coordination. The information obtained from eye-gaze is closely related to physical movements in any activity. It is important to establish a method to measure eye-hand coordination for extracting skilled elements and understanding the skill acquisition process. Using a system which consists of an eye mark recorder and a three-dimensional location measurement device, a method for measuring eye-hand coordination was proposed on the basis of the simultaneous measurement of eye-gaze and brush tip locations. After describing the measurement algorithm, the eye-hand coordination during calligraphy was exemplified. More concretely, using such a system, an attempt was made to show that the relationship between the line of eye-gaze and the brush tip stroke was different between a novice and an expert. In such a way, we suggested that the proposed method is promising for exploring the process of skill acquisition.
