A system and method for transmission of traffic sign board information to vehicles and relevance determination

摘要

The system described in this paper makes use of Bluetooth Low Energy (BLE) to broadcast traffic sign board information to vehicles. In the vehicle multiple sign board information is mapped to its display relative to each other. Further these signs are classified, as per the local traffic rules to help the driver. The paper describes algorithm to triangulate the position of a particular traffic sign board relatively based on message received by four Bluetooth radios in the vehicle from multiple sign boards. In addition paper has multi-level alerting step to classify the signs identified by the vehicle.
