The article presents issues related to the CWR (continuous welded track) and discusses the problems associated with its operation. An important part of the article is the results of simulation tests carried out for the developed model of a CWR track loaded with various values of longitudinal forces that may occur during operation. The forces act in the rail due to the occurrence of thermal stresses with values depending on the temperature change of the rail. In addition to simulation tests, the concept of experimental tests that will be performed on a selected section of the railway line is also presented. The MS-02 device will be used to measure longitudinal forces under various load conditions and to maintain the contactless path. The results of measurements made in the exploited track will be used in the long term to verify and further improve the numerical models.
本文介绍了连续焊轨道的有关问题,并对其运行中存在的问题进行了讨论。本文的一个重要部分是对所开发的CWR轨道模型进行模拟试验的结果,该模型加载了运行过程中可能发生的各种纵向力值。由于热应力的发生,力作用于钢轨,其值取决于钢轨的温度变化。除了模拟试验外,还提出了在选定的铁路路段进行试验试验的概念。MS-02装置将用于测量各种负载条件下的纵向力,并保持无接触路径。在开发轨道上的测量结果将长期用于验证和进一步改进数值模型。

The transport infrastructure management should be in line with sustainable development. Actions and activities that combine the environmental, social, and infrastructure expenditures optimally should be undertaken. The article presents a concept of life-cycle thinking that resolves these problems. The life cycle cost estimation method is a practical tool for managing transport infrastructure. The LCC analysis mustn’t generate more work than the benefits of it. Therefore appropriate assumptions should be made in constructing the method. The method assumes basic assumptions, taking into account the extensive scope of the research problem: transport infrastructure. The result of this article is a proposed mathematical model for estimating life-cycle costs. In the end, the practical use of the proposed methodology for determining the cost of the horizontal marking is provided.
交通基础设施的管理应符合可持续发展的要求。应采取最佳结合环境、社会和基础设施支出的行动和活动。本文提出了解决这些问题的生命周期思维概念。生命周期成本估算方法是交通基础设施管理的实用工具。LCC分析不能产生比它带来的好处更多的工作。因此,在构建该方法时应作出适当的假设。该方法假设了基本假设,并考虑到研究问题的广泛范围:交通基础设施。本文的结果是一个估计生命周期成本的数学模型。最后,提供了确定水平标记成本的建议方法的实际应用。

This article presents a synthesis of the assessment opportunities for implementing the automation of rail vehicles in Poland. The evaluation was to identify the threats to the automation of the above-mentioned vehicles and then assign to them the effects and probabilities of occurrence. A review of selected scientific, technical, formal, and legal sources was carried out for probability estimation. Definitions of Grades of Automation (GoA) were given, assigning technical and safety functionalities to them. The functional classification has been made concerning traffic safety. The problem of passengers' and drivers' social feelings towards introducing automatic vehicles has been pointed out. A formal and legal analysis of the possibility of implementing automatic rail vehicle traffic in Poland was also carried out.

Spatial planning is a derivative of several environmental, economic, market, technical, social, and political factors. In spatial planning of inland water ports, the configuration of the land surface, i.e., its shape (relief), and the presence and mutual location of objects and points of characteristic water ports are assumed as the main factors. Also, the port's planning, the planned structure of trade in goods, forecasted ship traffic, communication routes, applicable transshipment technology, and the anticipated demand for the development of shipping and inland waterway trade are of great importance in spatial planning and location.The article describes the criteria of logistic conditions for planning the inland port's location and transport accessibility in the lower section of the Vistula River. The intensity of vessel traffic, port spatial planning, and economic assessment were assessed.
空间规划是多种环境、经济、市场、技术、社会和政治因素的衍生物。在内河港口的空间规划中,主要考虑陆地表面的形态,即其形状(起伏),以及特色水港物点的存在和相互定位。港口的规划、货物贸易的规划结构、预测的船舶交通量、通信路线、适用的转运技术以及航运和内河贸易发展的预期需求,在空间规划和选址方面也具有重要意义。本文论述了维斯瓦河下游内河港口选址和交通通达性规划的物流条件标准。对船舶交通强度、港口空间规划和经济评价进行了评价。

The article presents a description, formulation and method of solving a certain problem of optimization of the structure of the distribution system in a selected logistics company in Poland. It was assumed that shipments are generated in the areas of address codes (more precisely: we know the volume of shipments between each pair of address codes in a time profile (day/week/month/year)). The problem of system structure optimization is decompressed into two subproblems: (1) location and dimensioning the company's branches by optimizing the number, location, bandwidth of branches and allocating code points to be serviced by the branches. The criterion for optimization is the total cost of establishing and maintaining branches and the costs of transporting shipments. From code points to the branch and vice versa; (2) location and dimensioning of the sorting plant and determination of the transport plan. Problem (1) solved using a modified, randomised clustering method k-means on the current data on the structure and volume of shipments from a certain courier company. Results of research on real data for the problem (1) are presented.

Tram track stiffness measurement based on the vision method 基于视觉法的有轨电车轨道刚度测量
Pub Date : 2019-06-01 DOI: 10.5604/01.3001.0013.6494

One of the main parameters characterizing properties of railway track is vertical stiffness. Provision of its appropriate value is crucial from the point of view of dynamic interactions occurring in a wheel-rail contact, what in turn translates into vehicle running behaviour and safety, passenger comfort, as well as further degradation of track condition. Track stiffness measurement is a cumbersome process requiring expensive equipment and can be carried out only if the line is closed. The following research is intended to estimate tram track vertical stiffness by means of vision method which can be performed during regular tram operation. Track deflections of tram line in the city of Poznan were carried out using high-speed camera and further used for vertical stiffness estimation.
表征铁路轨道性能的主要参数之一是竖向刚度。从轮轨接触中发生的动态相互作用的角度来看,提供适当的值是至关重要的,这反过来又转化为车辆的运行行为和安全性,乘客舒适度,以及轨道状况的进一步恶化。轨道刚度测量是一个繁琐的过程,需要昂贵的设备,只有在线路关闭的情况下才能进行。下面的研究是利用视觉方法估计有轨电车轨道的垂直刚度,这种方法可以在有轨电车正常运行时进行。利用高速摄像机对波兹南市有轨电车轨道位移进行了实测,并将其用于轨道垂直刚度估算。

Provision of its appropriate value is crucial from the point of view of dynamic interactions occurring in a wheel-rail contact, what in turn translates into vehicle running behaviour and safety, passenger comfort, as well as further degradation of track condition. Track stiffness measurement is a cumbersome process requiring expensive equipment and can be carried out only if the line is closed. The following research is intended to estimate tram track vertical stiffness by means of vision method which can be performed during regular tram operation. Track deflections of tram line in the city of Poznan were carried out using high-speed camera and further used for vertical stiffness estimation.\u0000\u0000","PeriodicalId":150174,"journal":{"name":"WUT Journal of Transportation Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123421761","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
