- Simulator for driving performance monitoringPublication . Raimundo, Diogo Alexandre Rodrigues; Lourenço, André Ribeiro; Abrantes, Arnaldo Joaquim CastroDriver and driving behaviour monitoring are a reality on new cars and on old fleets, driven by increased awareness about safety and environmental concerns. The numbers of car crashes are decreasing but still represent a huge concern, leading to the renewed interest on driving research topic. This thesis is centred on this theme and aims develop a driving simulator and modular software architecture that enables the variables related with the simulated vehicle, and that at the same time, acquires physiological, in particular the electrocardiogram (ECG), and behavioural variables from the driver. These data are registered aiming developing algorithms for drowsiness and fatigue, and also other related effects. The developed system is based on a message management and distribution module that uses the Publish/Subscribe pattern and the Open Sound Control communication protocol. All modules, including the simulator and the ECG module, communicate through this central module. The simulator is developed on the Unity platform and has some elements of artificial intelligence to control other cars present in the simulation. The results show that the proposed architecture is adequate for the proposed task, and can be used for drowsiness and fatigue studies. Preliminary results show that there are differences on driver variables (steering wheel movement) on drowsiness driving. More test are necessary to correlate with physiological variables.
