Methods and tools
DRIVE C2X project is above all a methodological activity, since the main objective is to show the most likely impacts of cooperative systems on users, society and provide useful information for further development of cooperative systems. The project comprises the following main elements in developing and implementing its methodology:
- Results of PRE-DRIVE C2X and its predecessors’ tools and methods necessary for successful test and evaluation of cooperative systems in a field operational trial.
- FESTA handbook for FOT methodology, especially the V-shaped FOT-chain to plan the testing procedure (Figure).
- Ongoing two large-scale European Field Operational Tests, euroFOT and TeleFOT.
The conception of DRIVE C2X field tests follows the project plan and will be held in three phases. The figure below shows the main stages of the field operation: Prepare, Operate and Evaluate.
The preparation phase consists of two steps. First, the test and validation framework will be defined. The focus will be on system and integration testing; in particular on the interoperability of the systems delivered by the partners. As a result, a full technical system validation, including guidelines and requirements for effective functional testing on the selected test sites, will be available for the next step.
Secondly, the test sites will be prepared and adapted. The focus will here be on implementing the common guidelines provided by the framework established in the first step. Specific descriptions of each test site will be delivered including full scale test scenarios.
The operate phase will start out with piloting. Each test site will be further adapted and integrated during the piloting/driving. The goal is to ensure that the test sites are ready for collecting FOT data. When this is achieved, the FOT management will begin. The test data management, fleet management and service/application management for the functional tests will be coordinated across all test sites. At the end of the driving phase a substantial amount of test data logged from vehicles and infrastructure will be available.
In the evaluation phase, the collected data will be used for assessing the selected services and applications. Based on the evaluation framework and the test design established in the preparation phase, the assumptions, hypotheses and requirements will be validated.
