新型码头钢-混凝土组合面板

基于特殊需要,提出了带型钢加劲肋的钢板-混凝土组合板这一新型组合码头面板。以加劲肋形式、组合板厚度和栓钉布置为参数,进行了9块组合板的力学性能试验。试验结果表明,通过适当地选择型钢加劲肋形式、合理地布置栓钉和确定混凝土厚度,可以保证组合作用的发挥。组合板的正截面承载力可按基于修正平截面假定的极限状态计算;组合板的变形,可在按现行钢结构设计规范计算的基础上,加上考虑界面滑移影响的附加变形值予以修正。计算值与试验值吻合较好。     

带有改编能力限制的编组计划优化模型及算法

本文用一个非线性０－１规模模型，来描述带有改编能力限制的技术直达列车编组计划问题。能力约束增加了该问题的计算难度。这是一个ＮＰＣ问题。因此，获得一个全局最优解是困难的。本文用模拟退火算法解该问题。该算法可以以很高的概率获得全局最优解。文末列出了两个数值例子，并分别同了考虑和不考虑改编能车约束两种情况下的计算结果。

Driver requirements and road traffic informatics

Initially the driver's role as a link in the driver-vehicle-road-traffic control-chain is discussed in a historical perspective. The gradual changes and the advantages and problems arising from these changes are discussed from behavioural point of view.Then the driver tasks are analyzed. A separation is made between trip planning, navigation, road following, traffic interaction, rule compliance, other than traffic tasks, car handling and speed choice. The relations between and the weights of these subtasks are discussed. Some existing driver behaviour models are reviewed in relation to the above mentioned tasks.Finally an effort is made based on the analyses of driver tasks and driver models to specify some general and some more specific potential advantages and problems with expected future RTI-systems.     

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. A brief discussion on the establishment of international standard is also mentioned as a final comment.
