SYSTEM MODEL FOR AUTONOMOUS ROAD FREIGHT TRANSPORTATION
Emerging info-communication and vehicle technologies
(especially vehicle automation) facilitate evolvement of
autonomous road freight transportation. The entire transport
system and its operation undergo a major change. New service
concepts are growing and the existing ones are being
transformed. The changing is particularly significant in
city logistics. However, there are debates about the ways
of automation of processes targeting improvement of capacity
utilisation and decrease of expenditures. The main research
questions of the paper are therefore: what properties of the
future autonomous freight transportation are presumed; what
system structure is to be constructed and how the system is
to be operated? After introducing the basic notions and
reviews of the current systems and developments,
the shifting from traditional freight transportation to
autonomous system is investigated by several aspects. A
system- and process-oriented analytical modelling method
has been applied. The main system constituents and their
connections are modelled. Finally, we elaborate the
operational model of road freight transportation, which is
applicable principally in metropolitan areas. In conclusion,
the presented results appoint the research and innovation
trends towards the automation of freight transportation

A Survey on 5G Usage Scenarios and Traffic Models
The fifth-generation mobile initiative, 5G, is a
tremendous and collective effort to specify, standardize, design,
manufacture, and deploy the next cellular network generation.
5G networks will support demanding services such as enhanced
Mobile Broadband, Ultra-Reliable and Low Latency Communications and massive Machine-Type Communications, which will
require data rates of tens of Gbps, latencies of few milliseconds
and connection densities of millions of devices per square kilometer. This survey presents the most significant use cases expected
for 5G including their corresponding scenarios and traffic models.
First, the paper analyzes the characteristics and requirements for
5G communications, considering aspects such as traffic volume,
network deployments, and main performance targets. Secondly,
emphasizing the definition of performance evaluation criteria
for 5G technologies, the paper reviews related proposals from
principal standards development organizations and industry
alliances. Finally, well-defined and significant 5G use cases are
provided. As a result, these guidelines will help and ease the
performance evaluation of current and future 5G innovations, as
well as the dimensioning of 5G future deployments.This work is partially funded by the Spanish Ministry of

D6.6 Final report on the METIS 5G system concept and technology roadmap
This deliverable presents the METIS 5G system concept which was developed to fulfil the
requirements of the beyond-2020 connected information society and to extend today’s
wireless communication systems to include new usage scenarios.
The METIS 5G system concept consists of three generic 5G services and four main enablers.
The three generic 5G services are Extreme Mobile BroadBand (xMBB), Massive Machine-
Type Communications (mMTC), and Ultra-reliable Machine-Type Communication (uMTC).
The four main enablers are Lean System Control Plane (LSCP), Dynamic RAN, Localized
Contents and Traffic Flows, and Spectrum Toolbox.
An overview of the METIS 5G architecture is given, as well as spectrum requirements and
considerations.
System-level evaluation of the METIS 5G system concept has been conducted, and we conclude that the METIS technical objectives are met.

The potential of naturalistic driving studies with simple data acquisition systems (DAS) for monitoring driver behaviour
This report addresses the important question regarding the potential of simple and low-cost
technologies to address research questions such as the ones dealt with in UDrive. The resources and efforts associated with big naturalistic studies, such as the American SHRP II and the European UDrive, are tremendous and can not be repeated and supported frequently, or even more than
once in a decade (or a life time..). Naturally, the wealth and richness of the integrated data, gathered by such substantial studies and elaborated DAS, cannot be compared to data collected via simpler, nomadic data
collection technologies. The question that needs to be asked is how many Research Questions (RQs) can be addressed, at least to some extent, by other low-cost and simple technologies? This discussion is important,
not only in order to replace the honourable place (and cost!) of naturalistic studies, but also to complement and enable their continuity after their completion. Technology is rapidly evolving and almost any attempt to provide a comprehensive and complete state of the art of existing technologies (as well as their features and cost) is doomed to fail. Hence, in chapter 1 of this report, we have created a framework for presentation, on which the various important parameters associated with the question at hand, are illustrated, positioned and discussed. This framework is denoted by “Framework for Naturalistic Studies” (FNS) and serves as the back bone of this report. The framework is a conceptual framework and hence, is flexible in the sense that its dimensions, categories and presentation mode are not rigid and can be adjusted to new features and new technologies
as they become available. The framework is gradually built using two main dimensions: data collection technology type and sample size. The categories and features of the main dimensions are not rigidly fixed, and their
values can be ordinal, quantitative or qualitative. When referring to parameters that are not numerical –even the order relation
among categories is not always clear. In this way –the FNS can be, at times, viewed as a matrix rather than a figure with order relation among categories presented along its axes.
On the two main dimensions of the FNS
–data collection technology type and sample size –other dimensions are incorporated. These dimensions include: cost, data access, specific technologies and
research questions that can be addressed by the various technologies. These other dimensions are mapped and positioned in the plot area of the FNS. Other presentations, in which the axes and the plot area are
interchanged, or 3 -dimensional presentations are performed, can be incorporated to highlight specific angles of the involved dimensions. The various technologies for data collection were mapped on the FNS. The technology groups include: mobile phone location services, mobile phone applications, telematics devices, built -in data loggers, dash
cameras and enhanced dash cameras, wearable technologies, compound systems, eye trackers and Mobileyetype technologies.
After this detailed illustrations of analyses that can be conducted using simple low-cost technologies are described. It is demonstrated
how temporal and spatial analysis can reveal important aspects on the behavioural patterns of risky drivers. Also one stand alone smartphone app can be used to monitor and evaluate smartphone us
age while driving. Most of the simple systems
relate to specific behaviour that is monitored (i.e. speeding , lane keeping etc.). Additionally,
certain thresholds or triggers are used to single out risky situations, which are
related to that behaviour. However, once those instances are detected, no information on the circumstances leading or
accompanying this behaviour are available. Typically, visual information (discrete or preferably continuous) is needed in order to
fully understand the circumstances.
Hence, upgrading simple (single-task oriented)
technologies by other technologies (most typically by cameras), can significantly improve researchers' ability to obtain information on the
circumstances, which accompany the detected risky behaviour. One of the most conceptually straightforward integrated systems is a system,
for which the basic technology detects the desired behaviour (e.g. harsh braking) and triggers a simple continuous dashboard
camera to save the relevant information, which occurs together with that behaviour. Many RQs can be addressed using this type of combined systems
