Automatic Vehicle Location (AVL) devices have become a fundamental part of fleet management in different transport modes. Besides determining the current geographical position, these devices incorporate additional functionalities to monitor vehicles, such as gas consumption, engine temperature, etc. However, critical security vulnerabilities in developing countries have been omitted by manufacturers, causing fleet transportation difficulties. This article presents an analysis of fleet transportation problems from the AVL operation and proposes a set of requirements to mitigate them. A prototype that meets these requirements is presented and tested.
自动车辆定位(AVL)设备已成为各种运输方式车队管理的基本组成部分。除了确定当前的地理位置外,这些设备还具有监测车辆的附加功能,如油耗、发动机温度等。然而,制造商忽略了发展中国家的关键安全漏洞,造成车队运输困难。本文分析了AVL运营中的车队运输问题,并提出了一套解决这些问题的要求。提出并测试了满足这些需求的原型。

Fleet Management and Control Systems (FMCS) have allowed public transport companies to improve their safety, efficiency and productivity. Therefore, national and local governments have supported implementation of such systems, to improve the mobility in cities. In some intermediate cities in developing countries, the implementation of these systems has been based on developed transport systems for large cities (with different operating conditions), without considering advances in service integration and standardization, in Intelligent Transportation Systems (ITS) frameworks. In addition, such implementations do not take into account enabling technologies such as new wireless communication standards featuring improved range, availability and accessibility. In order to improve this situation, we propose the design of an FMCS using ITS services based on an adequate ITS architecture, considering budget constraints and the need for a technology that improves relevant characteristics. We also evaluated the case of eight intermediate Colombian cities that are implementing transportation systems known as Strategic System for Public Transport (SSTP or SETP per its acronym in Spanish) in which one of the main components is an FMCS, and made some recommendations on the design of the system in these cities based in our purpose.
车队管理和控制系统(FMCS)使公共交通公司能够提高其安全性、效率和生产力。因此,国家和地方政府都支持实施这样的系统,以改善城市的流动性。在发展中国家的一些中等城市,这些系统的实施以大城市发达的运输系统(具有不同的运行条件)为基础,而没有考虑到智能交通系统框架中服务一体化和标准化方面的进展。此外,这种实施没有考虑到诸如具有改进范围、可用性和可访问性的新无线通信标准等使能技术。为了改善这种情况,我们提出了一种基于适当的ITS架构的使用ITS服务的FMCS设计,考虑到预算限制和改进相关特性的技术需求。我们还评估了8个中间哥伦比亚城市的案例,这些城市正在实施被称为公共交通战略系统(SSTP或SETP,根据其西班牙语首字母缩写)的交通系统,其中一个主要组成部分是FMCS,并根据我们的目的对这些城市的系统设计提出了一些建议。

Transportation is experiencing multiple technological disruptions. Nowadays, the mirriads of embedded sensors included in cars are used to produce rich datasets that improve the operation of the vehicle, support tasks for fleet management and improve safety and efficiency. In addition, autonomous and semi-autonomous vehicles communicate each to others and to their surrounding infrastructure to coordinate their operation and support new services. In these new scenarios, it is imperative to establish a secured, trusted and decentralized database that support these services. Recently, many researchers and companies have been exploring how Blockchain, a distributed ledger technology (DLT) successfully applied in other industries, can be used to support ITS services. This talk introduces blockchain and other distributed ledger technologies (DLT), presents some projects and initiatives aiming to apply these technologies in the transport industry and discusses which ITS services can be improved by using them.

Since the 90s, the Intelligent Transportation Systems (ITS) have always been looking for improving the technological solutions that has been applied into the transportation. In fact, today a concept known as “disruptive innovation” has began to re-order the way that ITS services can be achieved it. Disruptive Technology means that an established technology can be displaced by innovative solutions that require less resources and can grow exponentially, very often, shaking up the economy and structure of the related businesses. This paper presents some conclusions of the panel discussion regarding disruptive technologies held in the ITS LATAM 2019. Here, we present some aspects that practitioners should take into account in order to design and develop new ITS Services
自20世纪90年代以来,智能交通系统(ITS)一直在寻求改进已应用于交通运输的技术解决方案。事实上,今天一个被称为“颠覆性创新”的概念已经开始重新安排智能交通服务的实现方式。颠覆性技术意味着一项成熟的技术可以被创新的解决方案所取代,这些解决方案需要的资源更少,而且可以呈指数级增长,经常会动摇相关业务的经济和结构。本文介绍了在ITS LATAM 2019中举行的关于颠覆性技术的小组讨论的一些结论。在这里,我们提出了从业者在设计和开发新的智能交通系统服务时应该考虑的一些方面

Freight transportation is accounted for many negative externalities, such as congestion, emissions, noise, accidentality, among others. However, goods movement is an important issue regarding livability and competitiveness of a country, having more efficient transportation systems can be the difference between success or failure of economies as reported in the LPI (Logistics performance index). Recent technology development such as information systems, internet of things and collaborative economies can be an answer for solving transport inefficiencies. Literature has reported the use of intelligent transport system as a useful tool to improve efficiency, safety and environmental performance of vehicles and transport systems. Below novel system and its real application that is based the concepts of supply chain collaboration is presented, resulting in important benefits for companies involved, improving utilization rates, and diminishing number of trips and costs. Finally, some practical implications are presented.
货运考虑了许多负面外部性,如拥堵、排放、噪音、意外事故等。然而,货物流动是一个国家的宜居性和竞争力的重要问题,正如LPI(物流绩效指数)所报告的那样,拥有更有效的运输系统可能是经济成功或失败的区别。最近的技术发展,如信息系统、物联网和协作经济,可以解决运输效率低下的问题。文献报道了智能运输系统作为一种有用的工具来提高车辆和运输系统的效率、安全性和环境性能。下面介绍了基于供应链协作概念的新系统及其实际应用,为涉及的公司带来了重要的好处,提高了利用率,减少了旅行次数和成本。最后,提出了一些实际意义。

This paper analyzes a data set that contains reports of road accidents reported by the Municipal government of Bogota city, which occurred between 2016 and 2017, by using descriptive analysis and rule-model algorithms. The main objective is to characterize the road accident data and to highlight the variables that show a significant impact on the type of road accident. The results obtained shows the increase of road accidents by rush hour, from 6:00 to 8:00, one minor group from 12 m to 15:00 and another main group, from 17:00 to 19:00. Also, considering the day of the week, the days with the highest traffic accident frequency were Tuesday, Friday and Saturday. The rules-model obtained allowed to find out that the variables hour, day of week, locality and road geometry show a meaningful effect on the type of traffic accident; the model also allows to infer that the weather conditions does not pose a significant impact on assessing the type of traffic accident. The proposed rule model can be useful to propose accident prevention campaigns and to be incorporated into a traffic control system.
本文通过描述性分析和规则模型算法,分析了波哥大市政府报告的2016年至2017年期间发生的道路交通事故报告的数据集。主要目标是描述道路事故数据的特征,并突出显示对道路事故类型有重大影响的变量。结果表明:交通高峰时段(6:00 - 8:00)交通事故增加;交通高峰时段(12:00 - 15:00)交通事故增加;交通高峰时段(17:00 - 19:00)交通事故增加;此外,从一周的天数来看,交通事故发生频率最高的日子是周二、周五和周六。所得到的规则模型表明,小时、星期、地点和道路几何等变量对交通事故类型有显著影响;该模型还允许推断天气条件对评估交通事故类型没有重大影响。所提出的规则模型可用于提出事故预防活动,并可纳入交通控制系统。

Autonomous driving is expected to become a part of daily life in the near future. Large companies in the automotive industry plan for autonomous cars to arrive in the consumer market in the next few years and the need for them continues rising due to traffic accidents numbers been so high. In this paper, an autonomous driving system is proposed using a neural network for steering control and a fuzzy based system for pedals control. First, the input variables of the system are described and then the proper architecture of the proposed system is presented. As performance and safety are critical for this particular application, different metrics regarding those aspects are explained and then used for evaluation. Based on this, results that validate the proposed system are given.
