Context-dependent reconfiguration of autonomous vehicles in mixed traffic
Human drivers naturally adapt their behaviour depending on the traffic conditions, such as the
current weather and road type. Autonomous vehicles need to do the same, in a way that is both
safe and efficient in traffic composed of both conventional and autonomous vehicles. In this paper,
we demonstrate the applicability of a reconfigurable vehicle controller agent for autonomous
vehicles that adapts the parameters of a used car-following model at runtime, so as to maintain a
high degree of traffic quality (efficiency and safety) under different weather conditions.We follow
a dynamic software product line approach to model the variability of the car-following model
parameters, context changes and traffic quality, and generate specific configurations for each
particular context. Under realistic conditions, autonomous vehicles have only a very local knowledge
of other vehicles' variables.We investigate a distributed model predictive controller agent
for autonomous vehicles to estimate their behavioural parameters at runtime, based on their
available knowledge of the system.We show that autonomous vehicles with the proposed reconfigurable
controller agent lead to behaviour similar to that achieved by human drivers, depending
on the context.Junta de AndalucÃa MAGIC P12-TIC1814Ministerio de Ciencia, Innovación y Universidades HADAS TIN2015-64841-
