Acronym: TransAID
Project title: Transition Areas for Infrastructure-Assisted Driving
Duration: 36 months (01/09/2017 – 31/08/2020)

Description: TransAID is a project co-funded by the European Union's HORIZON 2020 program that aims to develop hierarchical traffic management schemes for mixed traffic (cooperative automated, automated, cooperative and conventional vehicles) along Transitions Areas of the road network, where automation level changes will be requested due to emergency and high complexity situations, and/or the absence of appropriate infrastructure equipment. TransAID will specify the aforementioned situations when hierarchical traffic management will be granted to prevent, manage or distribute (spatially and temporally) automation level changes. The proposed hierarchical traffic management schemes will be tested through simulations and field experiments. To this end automation prototypes for automated vehicles will be modelled and simulated in an open source microscopic traffic simulation tool (SUMO), and communication protocols will be developed for cooperative sensing and cooperative driving of connected/automated vehicles. Traffic models and communication protocols will be integrated into an efficient and modular open source simulation platform (iTetris) to evaluate the efficiency of the proposed hierarchical traffic management schemes. Real-world testing will be conducted on both actual test tracks and public roads encompassing cooperative automated, automated, cooperative and conventional vehicles.

Objectives: The purpose of TransAID is to enable the smooth coexistence of cooperative automated, automated, cooperative and conventional vehicles along Transition Areas by finding optimal infrastructure-assisted management solutions that will facilitate the cooperative maneuvering of the aforementioned vehicle types taking into account traffic safety and efficiency. The project findings will be used for the development of guidelines for advanced infrastructure-assisted driving. The guidelines will also include a roadmap defining activities and needed upgrades of road infrastructure in the upcoming 15 years in order to guarantee a smooth coexistence of cooperative automated, automated, cooperative and conventional vehicles.

HIT key role and responsibilities: HIT as project partner and technical leader of Work Package 3 “Modelling and Impact Assessment of Automated Vehicles” of the project has undertaken the following actions:

• Introduction of new metrics for the assessment of traffic dynamics at Transition Areas.
• Definition of the automated vehicles model requirements for the tested scenarios.
• Identification of existing and upcoming vehicle automations.
• Modelling of the motion of automated vehicles and the driver’s behavior during transitions in SUMO.
• Simulation of mixed traffic interactions in SUMO in the absence of hierarchical traffic management.
• Modelling and simulation of the cooperation between connected and automated vehicles in terms of vehicle maneuvering.
• Fine tuning of the driver models’ parameters based on the outcomes of the real-world prototype experiment.
