Provided is an information transmission method including: a type determination step of determining a type of information to be transmitted to a driver of a vehicle when the driver is driving the vehicle; a sound output step of outputting the information in the form of sound; and a display step of operating a display device to display an illumination pattern as a function of the determined type.

Systems, devices, and methods for detection of a scooter riding environment are described. A scooter alarm and pedestrian walkway detection system includes an alarm, a movement sensor configured to detect motion of a scooter and transmit motion data indicative of the motion to a processor, and an image capture device configured to detect features of a riding environment of the scooter and transmit riding environment data indicative of the features to the processor. The processor is configured to determine whether the riding environment of the scooter is a pedestrian walkway based on the motion data and the riding environment data. The processor is configured to activate the alarm in response to determining that the riding environment of the scooter is a pedestrian walkway.
