Risk area information transmitting apparatus, risk area information transmitting method, and computer-readable storage medium

A risk area information transmitting method comprising:

• receiving, from a first vehicle, risk area information about a plurality of risk areas which are identified by the first vehicle and which may pose a risk for the first vehicle to travel;
• receiving, from a second vehicle that is different from the first vehicle, request information for requesting position information of the plurality of risk areas;
• storing the position information of the plurality of risk areas received from the first vehicle;
• rearranging the plurality of risk areas that is stored in order of proximity to the second vehicle in response to receiving the request information from the second vehicle;
• and
• transmitting the position information of the plurality of risk areas that is rearranged to the second vehicle.

A non-transitory computer-readable storage medium having stored therein a program to cause a computer to function as:

• a receiving unit which (a) receives, from a first vehicle, risk area information about a plurality of risk areas which are identified by the first vehicle and which may pose a risk for the first vehicle to travel, and (b) receives, from a second vehicle that is different from the first vehicle, request information for requesting position information of the plurality of risk areas;
• a storage unit which stores the position information of the plurality of risk areas received from the first vehicle;
• a rearrangement unit which rearranges the plurality of risk areas stored in the storage unit in order of proximity to the second vehicle in response to receiving the request information from the second vehicle;
• and
• a transmitting unit which transmits the position information of the plurality of risk areas rearranged by the rearrangement unit to the second vehicle.
