Presentation information generation device and presentation information generation method

A presentation information generation device comprising:

• recommended position calculating circuitry to acquire ventilation equipment information indicating a state of ventilation equipment in a passenger car and to output recommended position information of a passenger by using the ventilation equipment information;
• presentation information generating circuitry to generate and output recommended position presenting information indicating a recommended position of the passenger in the passenger car by using the recommended position information output by the recommended position calculating circuitry;
• presentation information output circuitry to output, to a presentation device including a display, a speaker, or a projector, the recommended position presenting information generated by the presentation information generating circuitry;
• and
• ventilation command circuitry to determine a piece of ventilation equipment based on the recommended position for the passenger and to control the determined piece of ventilation equipment to perform ventilation in accordance with at least the recommended position for the passenger and a calculated airflow.
