Context Awareness and Priority Control for ITS based on Automatic Speech Recognition

Participants : Oyunchimeg Shagdar, Sakriani Watiasri Sakti.

Bringing rapid assistance to motorists involved in a traffic accident is an important service to be provided by Intelligent Transportation System (ITS). Existing proposals to automatic accident detection are based on the vehicle’s perception point of view. In [38] we introduce situational awareness based on the “understanding” of conversational speech of drivers/passengers using an automatic speech recognition (ASR) system. Context-aware priority control and congestion control schemes are presented to ensure coexistence of ASR-triggered applications and cooperative awareness messages (CAM) in the IEEE 802.11p system. Finally, application risk analysis and performance evaluations of ASR and V2X communications are carried out.
