iTETRIS: An Integrated Wireless and Traffic Platform for Real-Time Road Traffic Management Solutions

Wireless vehicular cooperative systems have been identified as an attractive solution to improve road traffic management, thereby contributing to the European goal of safer, cleaner, and more efficient and sustainable traffic solutions. V2V-V2I communication technologies can improve traffic management through real-time exchange of data among vehicles and with road infrastructure. It is also of great importance to investigate the adequate combination of V2V and V2I technologies to ensure the continuous and costefficient operation of traffic management solutions based on wireless vehicular cooperative solutions. However, to adequately design and optimize these communication protocols and analyze the potential of wireless vehicular cooperative systems to improve road traffic management, adequate testbeds and field operational tests need to be conducted. Despite the potential of Field Operational Tests to get the first insights into the benefits and problems faced in the development of wireless vehicular cooperative systems, there is yet the need to evaluate in the long term and large dimension the true potential benefits of wireless vehicular cooperative systems to improve traffic efficiency. To this aim, iTETRIS is devoted to the development of advanced tools coupling traffic and wireless communication simulators

iTETRIS: Scenarios for Simulation of Real-Time Road Traffic Management Solutions over Integrated Wireless Communication and Traffic Platforms

Wireless vehicular cooperative systems are an attractive solution to improveroad traffic management. V2V-V2I communication technologies can improve traffic management through real-time exchange of data among vehicles and with road infrastructure. Field Operational Tests will get first insights into the benefits and problems faced by such cooperative traffic management strategies; there is yet the need to evaluate in long term and large dimension the traffic efficiency improvements. iTETRIS will be the first tool capable of addressing such dimensions. The aim of this paper is to present in detail the traffic management scenarios and strategies that will be supported by iTETRIS

Integration vs fragmentation: alternative tactics of local mobility businesses in response to a global wave of market disruptions

In this paper we present the results of a facilitation process for consensus building among local mobility stakeholders (public transport providers, taxi associations, carpooling organizations, local authorities, etc.) aimed at identifying business and deployment strategies for travel assistance services integrating regular and on-demand mobility solutions. This process was centered around a service model deployed by the SocialCar platform, providing planning and booking services for multimodal trips, combining collective transport modes with community-based services (carpooling). Local consultation events were held in ten European cities where stakeholders were asked to assess four potential deployment scenarios enabled by the SocialCar service model. The business patterns will define an investment blueprint for local business development in Europe facing the current fragmented environment in the local transport market and including the key elements of legally sound public-private data integration, monetization and financing

iTETRIS: the Framework for Large-Scale Research on the Impact of Cooperative Wireless Vehicular Communications Systems in Traffic Efficiency

Cooperative vehicular ICT systems have been identified as an attractive technology to improve traffic management and safety, while providing Internet on the move. To achieve these objectives, cooperative vehicular communication systems allow the dynamic exchange of messages between vehicles, and between vehicles and infrastructure. To ensure the efficiency of cooperative vehicular ICT systems, it is crucial that the communication protocols are adequately designed and optimised, and that the applications using such communication capabilities are tested under realistic conditions. In this context, this paper presents the EU-funded iTETRIS platform that is being created to allow for a realistic and accurate evaluation of the design and impact of cooperative vehicular communication systems and traffic management policies under realistic large-scale scenarios

Traffic Simulation for All: A Real World Traffic Scenario from the City of Bologna

It is time consuming to set up a realistic traffic simulation scenario. Even though data is available, a large effort is needed to gather, convert and adapt all the data needed to replicate a part of a real road network. Available road networks usually have to be corrected and adapted to the used simulation model. The demand has to be converted or even generated using given measurements. The measurements must be imported into the simulation system’s architecture to allow the models’ calibration and validation. Additional road side structures must be converted into a proper representation and embedded into the scenario. Therefore, three real world traffic simulation scenarios of the city of Bologna are made available to the public. With these scenarios researchers are able to start their investigations with little preparation effort and can concentrate on their research questions

Public acceptance of SocialCar, a new mobility platform integrating public transport and car-pooling services: insights from a survey in five European cities

In this paper we present results of a technology acceptance and stated intention survey delivered in five European"br" sites to assess citizens’ attitudes and perceptions towards a new multi-modal mobility service named SocialCar,"br" developed under a EU H2020 research project and aimed at reducing individual car use. Such a service facilitates"br" a fruitful integration between public transport and car-pooling services, by means of a smartphone application and"br" advanced artificial intelligence algorithms. Citizens’ willingness to actively use the new App and to alter their"br" behavior as a result is therefore crucial for the success of the SocialCar concept and the creation of new collective"br" mobility practices. The survey provides insights on intention to use SocialCar and the related expected changes in"br" travel behavior for different groups in society. It also reveales differences between each site and highlights contextspecific"br" open challenges to address in order to favour future large-scale diffusion of the SocialCar mobility service."br" A real life test, to be conducted in Autumn 2017 and presented at the conference, will give us additional insight

iTETRIS - A System for the Evaluation of Cooperative Traffic Management Solutions

V2X communication - communication between vehicles (V2V) and between vehicles and infrastructure (V2I) - promises new methods for traffic management by supplying new data and by opening new ways to inform drivers about the current situation on the roads. Currently, V2X cooperative systems are under development, forced by both the industry and by the European Commission which supports the development as a part of its Intelligent Car Initiative. Within this publication, "iTETRIS", a new system for simulating V2X-based traffic management applications is described which aims on high-quality simulations of large areas. This is achieved by coupling two well-known open source simulators. The sustainability of the project is guaranteed by making the whole also available as an open source tool

ITETRIS: a modular simulation platform for the large scale evaluation of cooperative ITS applications

Cooperative ITS systems are expected to improve road traffic safety and efficiency, and provide infotainment services on the move, through the dynamic exchange of messages between vehicles, and between vehicles and infrastructure nodes. The complexity of cooperative ITS systems and the interrelation between its components requires their extensive testing before deployment. The lack of simulation platforms capable to test, with high modelling accuracy, cooperative ITS systems and applications in large scale scenarios triggered the implementation of the EU-funded iTETRIS simulation platform. iTETRIS is a unique open source simulation platform characterized by a modular architecture that allows integrating two widely adopted traffic and wireless simulators, while supporting the implementation of cooperative ITS applications in a language-agnostic fashion. This paper presents in detail the iTETRIS simulation platform, and describes its architecture, standard compliant implementation, operation and new functionalities. Finally, the paper demonstrates iTETRIS large scale cooperative ITS evaluation capabilities through the implementation and evaluation of cooperative traffic congestion detection and bus lane management applications. The detailed description and implemented examples provide valuable information on how to use and exploit iTETRIS simulation potential

SUMO2014 - Modeling Mobility with Open Data

Dear reader, You are holding in your hands a volume of the series „Reports of the DLR-Institute of Transportation Systems“. We are publishing in this series fascinating, scientific topics from the Institute of Transportation Systems of the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt e.V. - DLR) and from his environment. We are providing libraries with a part of the circulation. Outstanding scientific contributions and dissertations are here published as well as projects reports and proceedings of conferences in our house with different contributors from science, economy and politics. With this series we are pursuing the objective to enable a broad access to scientific works and results. We are using the series as well as to promote practically young researchers by the publication of the dissertation of our staff and external doctoral candidates, too. Publications are important milestones on the academic career path. With the series „Reports of the DLR-Institute of Transportation Systems / Berichte aus dem DLR-Institut für Verkehrssystem¬technik“ we are widening the spectrum of possible publications with a bulding block. Beyond that we understand the communication of our scientific fields of research as a contribution to the national and international research landscape in the fiels of automotive, railway systems and traffic management. This volume contains the proceedings of the SUMO2014 – Modeling Mobility with Open Data, which was held from 15th to 16th May 2014 in Berlin-Adlershof, Germany. SUMO is a well established microscopic traffic simulation suite which has been available since 2002 and provides a wide range of traffic planning and simulation tools. The conference proceedings give a good overview of the applicability and usefulness of simulation tools like SUMO ranging from new methods in traffic control and vehicular communication to the simulation of complete cities. Another aspect of the tool suite, its universal extensibility due to the availability of the source code, is reflected in contributions covering parallelization and interfacing improvements to govern microscopic traffic simulation results. The major topic of this second edition of the SUMO conference is open data. Several articles cover the acquisition and refinement of traffic networks as one of the fundamental data sources. Subsequent specialized issues such as data models for emissions and Bluetooth simulation are targeted as well. The conference’s aim was bringing together the large international user community and exchanging experience in using SUMO, while presenting results or solutions obtained using the software or modeling mobility with open data. Let you inspire to try your next project with the SUMO suite. There are many new applications in your environment. Prof. Dr.-Ing. Karsten Lemme
