Currently in the literature most authors define their own metrics and small differences in definitions can lead to confusion when comparing the results. To derive the set of metrics presented in this paper, several steps have been taken. First, a list has been made with all metrics known by the research partners. Afterwards, a set of base measures has been defined. Using that set, clear formulas for all metrics have been derived and are reported in this paper. Finally, an application example about a cooperative traffic light controller is given.

The application of such systems for novel cooperative traffic management strategies can introduce a lot of beneficial effects not only for road safety, but also for the economy related to transportation systems and the environmental impact. Despite this apparent set of promising features, City Road Authorities, which hold a key-role in determining the final adoption of such systems, still look at cooperative systems without sharing a clear opinion. This is mainly due to the current lack of definitive and solid evidences of the effectiveness of such systems when applied in the real world. In order to fill this gap and let Road Authorities estimate the usefulness of such technologies in achieving the objectives dictated by cities' traffic management policies, the EU consortium iTETRIS is developing a simulation platform for large scale testing of traffic management solutions making use of cooperative ITS systems. Thanks to its own distinguishing features, iTETRIS aims at becoming a good supporting tool for Road Authorities to implement preliminary tests on the effectiveness of ITS solutions prior to investing money for the physical deployment of the communication infrastructures allowing their functioning.

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. Pages 99-125 2 ITS systems. Cooperative ITS systems will provide new opportunities for more intelligent Smart Mobility services through the ubiquitous and continuous exchange of information between vehicles (Vehicle-to-Vehicle, V2V), and between vehicles and road infrastructure nodes (Vehicle-to-Infrastructure, V2I). The exchange of information such as the vehicles' position and speed will allow detecting potential road dangers and traffic congestions with sufficient time to react and avoid them. In addition, cooperative ITS communications will offer new means for the provision of Future Internet services on road transport.

An evaluation of existing descriptions of traffic light evaluation show that both, common measurement definitions as well as standardised simulation scenarios are missing. We present a definition of measurement methodology based on earlier projects, namely iTETRIS and FESTA. Additionally, the scenarios under development are presented, including basic, synthetic ones, as well as some that represent real-world networks.

Among the ITS applications developed within this project, ecoBalanced priority and ecoGreen wave focused on reduction of delay and stops. These applications were used to assess the impact in a network of four intersections located in Helmond, The Netherlands with microscopic simulation. The results showed that ecoBalanced priority reduces CO 2 emission for prioritized vehicles by more than 10% and for overall network by 5.9%. ecoGreen wave reduces total delay by 4.6% and number of stops by 4%.

This task was concerned with the development of adequate measures for estimating the benefits of traffic management application based on inter-vehicular communication and communication between vehicles and infrastructure on a city’s traffic. For the evaluation of a new system’s benefits, choosing proper measures is crucial. The work of task 210 was to evaluate existing metrics and to define measures which allow quantifying the performance of a city’s traffic and which shall be used for the research done within the iTETRIS project. This chapter describes the process of determining metrics to use, as well as the metrics themselves. The process starts with some initial and basic consideration on measures used within traffic planning, management and research. Afterwards, it is described how metrics were collected and how usable metrics were selected. Then, the metrics chosen to b...

In the following chapters, work done on allowing to simulate traffic management strategies is presented, starting with vehicle routing and rerouting and followed by the preparation of SUMO traffic lights model and design of traffic light algorithms that use information gained via V2X communication. Then, the extensions done for simulating vehicle movements with time steps below one second and work on allowing the simulation of advanced driver assistance systems (ADAS) are given. Because the road networks used within iTETRIS are already converted into the SUMO format, further information about the infrastructure, for example about the positions of ITS Roadside Stations can be retrieved from SUMO, t...

V2X communication -communication between vehicles (V2V) and between vehicles and infrastructure (... more 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.
