Intersection Decision Support System Using Game Theory Algorithm

Driver gap acceptance behavior traffic situation is considered a decision making traffic process and sometimes the driver could misjudge the offered gap size which could lead him to crash. Consequently, it should be introduced an intelligent system for driver guidance and assistance for preventing crashes; especially during adverse weather conditions: Intersection Decision Support (IDS). The proposed decision support system will depend on vehicle to vehicle (V2V) communication using game theory algorithm as an innovative approach for driver assistance. The planned driving assistance system is implemented inside the vehicle and contains a storage device. This storage device is responsible for collecting all the information related to the history of gap acceptance behavior for the driver. The database information contain the driver decision (accept or reject) and all the corresponding parameters like vehicle characteristics, surface, intersection properties, travel time needed and level of acceleration used by the driver. In addition, the agent inside the car will be receiving weather information from a station agency, in order to relate the impact of weather and the gap acceptance behavior. After storing the different driver, intersection and environment characteristics, the agent inside the vehicle will process all this information. Afterward, the agent will apply game theory algorithm with the opposing vehicles using DSRC for providing the driver the appropriate decision (accept or reject the offered gap). In summary, it is proposed an innovative framework for the coordination of physical characteristics of the vehicle and the Intellidrive agency (V2V communications) for decision making process. The system will give the driver the appropriate guidance for gap acceptance/rejection decision for intersection crashes prevention based on game theory. It is anticipated that this research will contribute in the future of intelligent transportation system (ITS), IntelliDrive systems and severe weather protection.
