从京沪高速公路（临沂段）路面大修中谈交通管制

高速公路大、中修过程中大多采用边通车,边维修的方法,因此,大、中修过程中的交通管制就显得尤为重要。以京沪高速公路路面大修(临沂段)施工过程中的交通管制为例,通过对减速距离等参数的分析,得出了交通管制与减速距离的关系,并对京沪高速公路(临沂段)大修中利用中央分隔带紧急开口绕行时交通诱导设施布置方案的安全性进行了分析与探讨。     

Development and Deployment of Public Transport Policy and Planning in Taiwan

Over the past decade, the escalating roadway congestion and environmental deterioration due to heavy use of private vehicles have provoked the Taiwan government to realize the importance of public transport systems. Under the “carrot-and-stick” rationales, the government has formulated public transport policies and exercised a series of related initiatives by providing sufficient and higher quality of public transport services so as to attract more private vehicle users. In this paper, the planning philosophy and policy formulation of Taiwan’s public transport development are highlighted. The most important initiatives, including the Five-year Enhancement of Mass Transportation Program and the upgrading public transport schemes in the National Development Plan are examined. Based on previous experience and lessons, we point out the most challenging issues that the government will encounter. Suggestions for the future of public transport planning are also addressed.

船舶液力耦合器的人工神经网络的数学建模

从船舶动力装置动态建模与仿真的实际需求，引出了其主要部件之一的液力耦合器数学建模在稳／动态特性研究中的重要性，以及利用其试验曲线(输入特性形式)作为数据源去构建准稳态数学模型的困难之处：寻找一种通用的数学表达形式，以实现①液力耦合器在额定工况及其附近的试验曲线的内插与外廷；②过渡工况液力耦合器数学模型的设计(如液力耦合器接合和脱开过程其滑差从100％向额定滑差值方向的变化)。本文介绍了人工神经网络方法在液力耦合器动态建模中的应用。文章先介绍了其数学建模的思路和要点：①选择人工神经网络算法(包括传递函数)与结构(人工神经网络隐含层数目和神经元个数)；②提高人工神经网络泛化能力的措施；③利用专业知识扩充人工神经网络训练用的数据样本。然后叙述了其数学模型在某船舶动力装置稳态、动态特性计算机仿真研究中的某些有意义的结果：①正常航行(四机双桨)稳态工况时各车令下液力耦合器的滑差；②不同螺旋桨螺距下的液力耦合器接合过程的滑差变化；③怠速→前进五的急加速过程的滑差变化。     

Japanese perspective of driver information systems

A perspective view of of Japanese R&D activities of Driver Information Systems is given from the standpoint of developing joint projects by public and private sectors. First, a brief history of the R&D activities is illustrated from above mentioned standpoint. Then, two major projects, AMTICS and RACS, and the social backgrounds of these projects are explained. In order to give a clear idea of both projects some technical details are treated.Based on the history and the present status of the developments, the basic design conceptions of Japanese Driver Information Systems are explained and several factors or reasons which have influenced to the design conception are discussed. Then, the promoting systems of the R&D activities are generally explained and present status of the projects and future problems in developing more advanced systems are also handled.
