Vigo (Spain)
Overview of the demonstration
The Vigo LL testing area is located in the heart of the city, the Vigo Gran Vía. This emplacement is selected as the best option which keeps a good balance between safety requirements, traffic flow affection, reproduction of real conditions and feasibility of data collection for evaluation.
The lane selected for demonstrations is the adjacent one to the boulevard in upstream and downstream senses of circulation. This lane will be separated by cones and circulation will be forbidden to general traffic vehicles. The services showcased in the demonstration were:
Cooperative ITS services I2V
-
-
- SPAT/GLOSA
- Enhanced GLOSA with queue detection with camera.
- In Vehicle Information (IVI): Road Warnings: traffic jams, accidents and road works.
- Cyclist proximity: It provides geopositioned data about cyclist circulating with Vigo Driving APP in real time.
- Pedestrian on the road. In this service, the pedestrian is detected by CCAV sensors.
-
Cooperative ITS Services V2I
- Position and speed of CAV
- Destination and planned route communication
- Obstacle/event detection by CAV sensors. Pedestrian on the road (CPM messages)
- VRU Vigo Driving APP for cyclist and scooters.
Adapted Management Strategy
- Coordinated traffic management supporting CCAM. Traffic light priority
- Platooning splitting avoidance
Vehicles
2 CAV of SAE level 3-4
Duration
4 to 17 November

Test scenario
The scenarios for testing phase and data collection were structured in:
- Pre-testing scenarios: Vehicle engineers visited Vigo with portable equipment for pretesting, data collection and pre-configurations.
- On site testing. Test scenarios were defined following a complexity scalability, adding new features as soon as the basic ones were consolidated.
From April to October, several operations were carried out in advance before the CCAVs were physically in Vigo.
Test scenario 1. UC#4 Mutual awareness between CCAM fleet, infrastructure and other users
Data interchange Scenario
The two CCAVs circulate by testing area. All ITS warnings and events received and identified as relevant for the position and heading of CCAV are recorded during the session.
GLOSA Scenario
Alternation of two trips with GLOSA (Vehicle adapt speed and/or stop/pass in traffic light in autonomous mode) and two trips without GLOSA (at each intersection either vehicle gives control to the driver or driver override in order to cross the intersection according traffic light status) was the approach used to calculate KPIs in the test scenario.
Test scenario #2. UC#5 Management strategy adapted to CCAM based on V2I interaction and UC#4 Mutual awareness between CCAM fleet, infrastructure, and other users.
Different batteries of tests are alternated with and without priority service enabled for obtaining KPIs by comparation.
Use Case:
1. Mutual awareness CCAM fleet-infrastructure (traffic and operation)-other users (CCAM or not).
The LL will enhance data interchange among vehicles, infrastructure and pedestrians or cyclists, building a precise virtual map shared among all the connected users.
2. Management strategy adapted to CCAM based on vehicle-to-infrastructure (V2I) interaction
The use case will provide regulation in the traffic light network to raise the capacity of the urban network by enabling a more efficient performance of CCAV fleets by proposed services.
Objectives
- Enable and analyze data and information interchanged among the CCAV fleets, Traffic Infrastructure and other users (connected or not)
- Define, deploy and test traffic management strategies on urban roads that enable smooth, balanced, safer and more efficient operation of the CCAV in coexistence with other users.
- Study the safety and efficiency impact of CCAM and global traffic quality improvement.
Key outcomes
More than 15 GB of data collected in 612 trips (full round to defined circuit with 2 traffic light intersection crossings) and a total of 245 km.
