A comprehensive overview of the protocols associated with Intelligent Transportation Systems

This white paper offers a comprehensive overview of the protocols utilized in the field of intelligent transportation systems (ITS). The paper presents a comprehensive overview of protocols from all layers of the Open System Interconnection (OSI) model. The protocols encompass a range of communication technologies, including ad-hoc, mobile broadband, and fiber-optic cable. All of these protocols are utilized in the field of intelligent transportation systems (ITS) and must exchange information at some point. The current development leads to a much tighter connection between ecosystems that were previously isolated or not connected. This situation necessitates a comprehensive understanding of the protocols at all layers to ensure the establishment of safe and secure applications within the field of intelligent transportation systems (ITS).

Multi-Channel Operation for the Release 2 of ETSI Cooperative Intelligent Transport Systems

Vehicles and road infrastructure are starting to be equipped with vehicle-to-everything (V2X) communication solutions to increase road safety and provide new services to drivers and passengers. In Europe, the deployment is based on a set of Release 1 standards developed by ETSI to support basic use cases for cooperative intelligent transport systems (C-ITS). For them, the capacity of a single 10 MHz channel in the ITS band at 5.9 GHz is considered sufficient. At the same time, the ITS stakeholders are working towards several advanced use cases, which imply a significant increment of data traffic and the need for multiple channels. To address this issue, ETSI has recently standardized a new multi-channel operation (MCO) concept for flexible, efficient, and future-proof use of multiple channels. This new concept is defined in a set of new specifications that represent the foundation for the future releases of C-ITS standards. The present paper provides a comprehensive review of the new set of specifications, describing the main entities extending the C-ITS architecture at the different layers of the protocol stack, In addition, the paper provides representative examples that describe how these MCO standards will be used in the future and discusses some of the main open issues arising. The review and analysis of this paper facilitate the understanding and motivation of the new set of Release 2 ETSI specifications for MCO and the identification of new research opportunities.

The CONVERGE project -- A systems network for ITS

Various German and European research projects created several isolated solutions for intelligent transportation systems (ITS) infrastructure. As a matter of fact, a lot of those solutions are temporary. The backend architecture provided by those systems is mostly focused on only supporting test and evaluation of topics in the context of vehicular based application and communication. There have been a couple of research projects, which have evaluated the different communication paths between ITS roadside or central stations and vehicle stations. The current approach of the research community is to combine multiple ways of communication to provide the greatest benefit. Two of the most promising technologies are cellular communication and Car-to-Car communication. As there have already been research projects which evaluate the possibilities of one of those communication paths, few research projects have evaluated how those paths could complement each other. The structure of the Car2X Systems Network will be based on the Internet, in which different and independent participants are working equally together over standardized interfaces and protocols. However, the Car2X Systems Network needs some special solutions, as the concepts of the Internet are not entirely applicable to the requirements of the ITS world. Especially the strict security and privacy considerations of ITS environments are not or only insufficiently addressed in current state-of-the-art internet services. Furthermore, network requirements like Quality of Service needs also to be considered. Thus, the Car2X Systems Network aims to provide open, standardized, secure and interchangeable interfaces for each possible participant of the ITS environment.

Secure Hybrid ITS Communication with Data Protection

In the future world of safe traffic, intelligent transportation systems play a vital role. The connections between traffic participants and systems on the one and infrastructure and service providers on the other side are a necessary prerequisite for informed and safe driving. The key for the connection between all stakeholders is a reliable and secure connection. Reliability can be achieved in different ways. For the information exchange, we utilize hybrid communication technologies in different scenarios. This includes long-range technologies like DAB+ and cellular networks and short- and medium-range technologies like ETSI ITS G5 or RFID. Those technologies can only be used if messages transmitted via the wireless communication links are protected. Protection not only means encryption but most importantly means to verify if the data was sent by a legit sender. This is a necessary requirement for a recipient to trust the data received. In ITS, transmitted data could be used for user tracing and collection of user data. Therefore, a communication system should be designed in such a way that personal user data is protected. The user must be untraceable, but nevertheless able to use all services without limitations. In this paper, we describe the approach and ideas we took to design a secure hybrid communication architecture that is at the same time data protection friendly.

CONVERGE -- Future IRS-Infrastructures as Open Service Networks

In the past years there has been significant progress in Intelligent Transport Systems in the domains of traffic management, driver assistance and driver information. Within the German research project COmmunication Network VEhicle Road Global Extension (CONVERGE), a system architecture for the flexible interaction between different service providers and communication network operators will be designed and implemented, called Car2X Systems Network architecture. The Car2X Systems Network will establish a completely new open communication-, services-, and organization architecture that reflects state of the art communication technologies and IT security. Through well-defined access methods, service providers like traffic control centers or vehicle manufacturers can be integrated into the open and secure system network. The ultimate goal is the decentralized and dynamic coupling of all systems and actors across national and organizational borders. This paper is focusing on the requirements and the concept of a service-oriented architecture for publishing and finding services inside the system with intelligent information distribution based on geographical and organizational conditions.

Vehicle infrastructure -- communication to support driver assistance systems

The area of vehicle-to-infrastructure (C2I) communication has become an increasingly important area in the field of C2X communication in recent years. It is on the same level as vehicle-to-vehicle (C2C) communication and uses the same technologies and protocols. In today's research environment, the consensus is that IEEE standard 802.11p is used for communication. Based on this, the Car-2-Car Communication Consortium is developing a unified protocol stack for effective and efficient C2X communication. Roadside units (RSU) can be used to support driver assistance systems. Through targeted information processing and information distribution, they are intended to expand the vehicle's capabilities through additional data and also provide information that could not be made available through C2C communication alone.

Automatisierte Verwaltung von ITS Roadside Stations für den simTD Feldversuch

The simTD project is the first large-scale field trial for vehicle-to-vehicle and vehicle-to-infrastructure communication in Europe. It consists of up to 400 vehicles and over 100 infrastructure-side communication units, so-called ITS Roadside Stations (IRS). With the large number of remote units, a powerful management system is needed to ensure that all necessary administrative tasks for the IRS can be performed: from basic configuration, to installation and management of applications, to handling and troubleshooting of the IRS themselves. Furthermore, a graphical interface for administration will be created, an encrypted communication channel will be implemented, and a framework for third-party applications will be developed. Due to the importance of management for the entire project, the management system must be highly available.

Cloud-based traffic data fusion for situation evaluation of handover scenarios

Upcoming vehicles introduce functions at the level of conditional automation where a driver no longer must supervise the system but must be able to take over the driving function when the system request it. This leads to the situation that the driver does not concentrate on the road but is reading mails for example. In this case, the driver is not able to take over the driving function immediately because she must first orient herself in the current traffic situation. In an urban scenario a situation that an automated vehicle is not able to steer further can arise quickly. To find suitable handover situations, data from traffic infrastructure systems, vehicles, and drivers is fused in a cloud-based situation to provide the hole traffic environment as base for the decision when the driving function should be transferred best and possibly even before a critical situation arises

Neurocognitive and traffic based handover strategies

The level of automation in vehicles will significantly increase over the next decade. As automation will become more and more common, vehicles will not be able to master all traffic related situations for a long time by themselves. In such situations, the driver must take over and steer the vehicle through the situation. One of the important questions is when the takeover should be performed. Many decisive factors must be considered. On the one hand, the current traffic situation including roads, traffic light and other road users, especially vulnerable road users, and on the other hand, the state of the driver must be considered. The goal is to combine neurocognitive measurement of the drivers state and the static and dynamic traffic related data to develop an interpretation of the current situation. This situation analysis should be the basis for the determination of the best takeover point.

Trinational Automated Mobility

Safe, environmentally conscious and flexible, these are the central requirements for the future mobility. In the European border region between Germany, France and Luxembourg, mobility in the world of work and pleasure is a decisive factor. It must be simple, affordable and available to all. The automation and intelligent connection of road traffic plays an important role in this. Due to the distributed settlement structure with many small towns and village and a few central hot spots, a fully available public transport is very complex and expensive and only a few bus and train lines exist. In this context, the trinational research project TERMINAL aims to establish a cross-border automated minibus in regular traffic and to explore the user acceptance for commuter traffic. Additionally, mobility on demand services are tested, and both will be embedded within the existing public transport infrastructure.
