This paper discusses how Smart Logistics could be linked with the Smart Border concept earlier proposed for the El Paso – Ciudad Juarez bi-national metropolitan area. The focus is on the international road and pedestrian bridges connecting these two cities as these were identified as bottlenecks for cross-border movement of goods and cross-border mobility of people. The proposal presents the basic strategic and operative framework. Examples of smart logistics measures that could be implemented on the border and beyond the border such as autonomous vehicles, micro depots and crowd shipping are presented and discussed. The paper shall be understood as the case for the cross-border logistics in relation to the Smart Border concept and as the starting point for further exploration.
本文讨论了如何将智能物流与之前为埃尔帕索-华雷斯城两国大都市区提出的智能边境概念联系起来。重点是连接这两个城市的国际道路和人行天桥,因为这些被确定为跨境货物流动和人员跨境流动的瓶颈。该建议提出了基本的战略和行动框架。介绍和讨论了可以在边境和边境以外实施的智能物流措施,如自动驾驶汽车、微型仓库和人群运输。本文应被理解为与智能边境概念相关的跨境物流案例,并作为进一步探索的起点。

The authors present the results of their practical research on the navigation of people with disabilities inside buildings using iBeacon technology. This technology's navigation potential lies in indoor use and everywhere, where GPS-like systems fail due to lack of coverage. Even though iBeacon technology is simple (it only broadcasts a signal), its potential is high if paired with suitable software. In such a case, it may not only serve as a navigation system, but also generate information. The authors used multi-criteria analysis to find out what type of iBeacon is the most suitable one for indoor navigation of people with disabilities. Their analysis also resulted into a set of recommendations for distribution and settings of iBeacon with respect of the topology of the building.
作者介绍了他们使用iBeacon技术在建筑物内为残疾人导航的实际研究结果。这项技术的导航潜力在于室内和任何地方的使用,在这些地方,类似gps的系统由于缺乏覆盖而失效。尽管iBeacon技术很简单(它只发射一个信号),但如果搭配合适的软件,它的潜力还是很大的。在这种情况下,它不仅可以作为导航系统,还可以产生信息。作者使用多标准分析找出了哪种类型的iBeacon最适合残疾人的室内导航。他们的分析还得出了一组关于iBeacon的分布和设置的建议,这些建议与建筑的拓扑结构有关。

Highway management implemented to a city ring road should be indisputably integrated into Smart City strategies. It is believed that the multi-agent approach should facilitate such an integration since it is able to cover heterogeneous entities. For this reason, an agent based environment for the simulation of different control strategies to highway management was required. The software tool Anylogic was selected for this issue, since it contains built-in traffic library and allows agent based modeling. In the previous work, the architecture and the framework model for the simulation environment were defined. This paper is focused on the highway model itself. It deals with the problems which had to be overcome when modeling a highway segment in Anylogic. It includes the infrastructure with ramps and exits, loop detectors for traffic flow mapping and gantries for transmission of control actions to the drivers. The generation and the setting of traffic flow, together with its mapping and the drivers' reaction on the control measures, are also covered. The highway model was validated with real data from Prague Ring Road and, within the mentioned framework model, it is now prepared for the simulation of different scenarios.
对城市环路实施高速公路管理,应无可争议地纳入智慧城市战略。人们认为,多代理方法应该促进这种集成,因为它能够覆盖异构实体。为此,需要一个基于智能体的环境来模拟不同的公路管理控制策略。这个问题选择了Anylogic软件工具,因为它包含内置的流量库,并允许基于代理的建模。在前面的工作中,定义了仿真环境的体系结构和框架模型。本文主要研究高速公路模型本身。它处理了在Anylogic中高速公路段建模时必须克服的问题。它包括坡道和出口的基础设施,用于交通流映射的环路探测器和用于将控制动作传输给驾驶员的龙门。交通流的产生和设置,以及它的映射和驾驶员对控制措施的反应,也被涵盖。高速公路模型用布拉格环路的真实数据进行了验证,并且在上述框架模型中,它现在准备用于不同场景的模拟。

Autonomous vehicles contribute to the development of on-demand mobility services for commuters in a metropolitan area. The aim of our research is to develop a method of determining the number of collection points for a shared autonomous vehicle-based mobility service. In the service, microcars are used to serve the demands. However, only the first and last kilometers of a trip are done by the microcars; they are transported together on a trailer for common route sections. The boarding and alighting of microcars are managed in collection points. The collection point number determination method is based on Newton’s model of gravity; variables about territorial and commuting aspects were considered (e.g., distance, public transportation availability, population, job opportunities, modal share, willingness to change). The method was applied to a certain part of the Budapest metropolitan area as a case study. The results contribute to the introduction of autonomous vehicle-based mobility services.
自动驾驶汽车有助于在大都市地区为通勤者提供按需移动服务。我们研究的目的是开发一种确定基于共享自动驾驶汽车的移动服务的收集点数量的方法。在服务中,微型汽车被用来满足需求。然而,只有旅程的前一公里和最后一公里是由微型汽车完成的;它们一起用拖车运输到公共路段。微型车的上、下均在集合点进行管理。收集点数量的确定方法基于牛顿引力模型;考虑了地域和通勤方面的变量(例如,距离、公共交通可用性、人口、工作机会、模式共享、改变的意愿)。该方法应用于布达佩斯大都市区的某一部分作为案例研究。研究结果有助于引入基于自动驾驶汽车的移动服务。

Rapid urbanization along with the population growth increases the pressure on existing transportation systems which boosts the needs for the provision of a well-connected and efficient Public Transport Systems (PTSs) to meet the mobility needs of the people. In this framework, it is important for the PTSs of a region to perform at certain quality levels including availability (both spatial and temporal), accessibility, affordability, environmental protection etc. Among all these features, the most important is the accessibility to stops since access to/from the public transport is provided only through them. This paper is focused on the development of a novel methodology to evaluate the accessibility of public transport at different levels of measurements of a region/ city using Public Transport Accessibility Index (PTAI). It is developed based on the accessibility of public transport stops to the population, service centers and connectivity to nearby regions. The proposed approach is effective in terms of highlighting the least accessible areas towards the improvement of existing public transport connections or planning of new services. An application of proposed methodology has been presented using a mathematical example.
快速的城市化和人口增长增加了对现有交通系统的压力,这增加了对提供连接良好和高效的公共交通系统(pts)的需求,以满足人们的出行需求。在这一框架下,重要的是一个区域的PTSs在一定的质量水平上运行,包括可用性(空间和时间)、可达性、可负担性、环境保护等。在所有这些功能中,最重要的是到车站的可达性,因为进出公共交通只能通过它们。本文研究了一种基于公共交通可达性指数(PTAI)的区域/城市公共交通可达性评价方法。它是基于公共交通站点对人口的可达性,服务中心以及与附近地区的连通性而开发的。建议的方法是有效的,因为它突出了最不容易到达的地区,以改善现有的公共交通连接或规划新的服务。通过一个数学实例,给出了该方法的应用。

This paper is focused on railway timetabling in suburban areas and presents a new proposal of possible variants of operational concepts for railway line 171 Praha – Beroun, especially variants of zone-oriented timetable. This type of timetable is generally found as an attractive suburban railway transport operational concept on busy radial railway lines and can be an important part of the active policy of Smart Cities. At first, the method for timetable transportation assessment is proposed. Subsequently, there are described principles of zone-oriented timetable. It is followed by a proposal of different operational concept variants for railway line 171 Praha – Beroun (one-level service and several variants of zone-oriented timetable). Finally, all proposed variants of the operational concept are assessed in a transportation way.
本文以近郊地区的铁路时刻表为研究对象,对171号线Praha - Beroun的运营概念提出了一种可能的变化方案,特别是以区域为导向的时刻表变化方案。这种时刻表通常被认为是繁忙的径向铁路线路上一种有吸引力的郊区铁路运输运营概念,可以成为智慧城市积极政策的重要组成部分。首先,提出了时间表运输评价方法。随后,阐述了分区时刻表的原则。随后提出了171号铁路Praha - Beroun的不同运营概念变体(一级服务和几种面向区域的时间表变体)。最后,以运输的方式对所有提出的操作概念变体进行评估。

Heart Rate Changes in Critical Situations in a Vehicle Simulator 车辆模拟器危急情况下的心率变化
Pub Date : 2021-05-27 DOI: 10.1109/SCSP52043.2021.9447391

This article is about a study of the heart rate of drivers in a vehicle simulator and its changes when the drivers are confronted with critical and potentially collision situations. The drivers' heart rate was measured while driving in a car simulator. After traversing a certain section of the created simulation route, a critical situation occurred in the simulation, which forced the drivers to react quickly. The aim of this study was to determine the probability of a significant increase in heart rate of drivers after the confrontation with this critical situation and to deduce from this whether the measurement of heart rate in driving simulators can be used as an indicator of critical or stressful situations. The Wahoo Tickr X chest strap was selected to measure the heart rate of the drivers and 30 drivers of different sexes and ages were measured. A total of three minutes of heart rate recordings were evaluated per driver, two minutes before the start of the critical situation and one minute after the start of the critical situation. Three different methods were developed to identify a significant increase in heart rate after the start of the critical situation, and a comparison between the parameters of the section before the start of the critical situation and the section after the start of the critical situation was also performed. The first main result of this study is the probability of a significant increase in the heart rate of drivers in a vehicle simulator in critical situations. The second main result is a comparison of the extent to which this increase in heart rate is unique to the critical situation, i.e. whether similar or greater increases in heart rate occur even before the critical situation. The results of this study are generally applicable on any vehicle simulators including simulators developed for smart city vehicles.
本文研究了驾驶员在车辆模拟器中面对危险和潜在碰撞情况时的心率变化。驾驶员在汽车模拟器中驾驶时测量心率。在通过创建的仿真路线的某一段后,仿真中出现了紧急情况,迫使驾驶员迅速做出反应。本研究的目的是确定驾驶员在面对这种危急情况后心率显著增加的概率,并由此推断驾驶模拟器中心率的测量是否可以作为危急或紧张情况的指标。选择Wahoo Tickr X胸带测量司机心率,对30名不同性别和年龄的司机进行测量。每位驾驶员在危急情况开始前两分钟和危急情况开始后一分钟,总共评估了三分钟的心率记录。制定了三种不同的方法来识别危急情况开始后心率的显著增加,并对危急情况开始前和危急情况开始后的截面参数进行了比较。本研究的第一个主要结果是在车辆模拟器中驾驶员在危急情况下心率显著增加的可能性。第二个主要结果是比较这种心率的增加在多大程度上是危急情况下所特有的,即在危急情况之前是否会发生类似或更大的心率增加。本研究的结果普遍适用于任何车辆模拟器,包括为智慧城市车辆开发的模拟器。

The effect of modal shift to micromobility upon the parking demand 交通模式向微交通的转变对停车需求的影响
Pub Date : 2021-05-27 DOI: 10.1109/SCSP52043.2021.9447396

Modal shift to micromobility, namely bicycle and scooter, has the potential to impact urban space through the changes in parking demand. Investigating the factors affecting the shift and its likelihood is necessary to forecast the changes. In this paper, a novel method for the estimation of parking demand generated by rising micromobility use is presented. Private and shared ownerships, docking types (dockless and docked), users’ preferences, trip characteristics, and endogenous factors are considered. Sections of a questionnaire survey are proposed to provide inputs to the method. The method is validated using a simulation. The key findings are: (i) shifting from car use reduces car parking demand by 37%, freeing urban space up; (ii) public transport/walking shift to micromobility requires 17% more parking spaces for bicycle and scooter, increasing the demand for urban space; (iii) shared docked mobility forms require 67% more urban space than dockless ones. The application of the method allows a detailed analysis of the barriers to modal shift and facilitates the proposition of efficient measures to improve the shifting.
交通方式向微型交通的转变,即自行车和踏板车,有可能通过停车需求的变化影响城市空间。调查影响转变的因素及其可能性对于预测变化是必要的。本文提出了一种估算微机动车辆使用量增加所产生的停车需求的新方法。考虑了私人和共享所有权、停靠类型(无停靠和停靠)、用户偏好、出行特征和内生因素。问卷调查的部分建议提供输入的方法。通过仿真验证了该方法的有效性。主要发现有:(1)减少汽车使用减少了37%的停车需求,释放了城市空间;(ii)公共交通/步行向微型交通转变,需要增加17%的自行车和踏板车停车位,增加对城市空间的需求;(三)共享的停靠式出行方式比无停靠式出行方式需要的城市空间多67%。该方法的应用可以详细分析模态转换的障碍,并有助于提出有效的措施来改善转换。

Urban comfort and safety go along with travel and traffic management for the cities. Facing automatization of transport brings necessity for the ITS solutions to provide efficient communication between vehicles, infrastructure and other traffic participants. Parking in the cities is a daily travel related task. Efficient automated parking solutions can contribute to individual time management as well as to reduction of traffic flow that is connected with parking spot search – especially in big cities. User acceptance of new technologies that arise with automated driving depends on their usability and interface. This paper presents a pilot demonstration of automated parking function with a mobile app interface. Observation of visual behavior (eye tracking) provide analyses of automated parking function and mobile app of modified electric prototype of e-vehicle "Skoda Rapid".
城市的舒适和安全伴随着城市的出行和交通管理。面对交通运输的自动化,智能交通系统解决方案必须在车辆、基础设施和其他交通参与者之间提供有效的通信。在城市里停车是一项与日常出行相关的任务。高效的自动停车解决方案有助于个人时间管理,并减少与停车位搜索相关的交通流量,尤其是在大城市。用户对自动驾驶新技术的接受程度取决于它们的可用性和界面。本文提出了一个基于移动app界面的自动停车功能的试点演示。视觉行为观察(眼动追踪)对电动汽车“斯柯达捷”改进型电动样车的自动泊车功能和移动应用进行分析。
