Path information providing server, method of providing path information, and terminal

A path information providing server, comprising:nan environmental information collecting unit configured to collect environmental information of data sensed by a sensing device and information on a location at which the data is sensed;a path searching unit configured to select a path from a departure location to a destination that are identified in a path information request received from a terminal device;a path information generating unit configured to determine a type of environmental information to be mapped to the path according to a purpose for a trip identified by a user of the terminal and to map the determined type of environmental information to the path based on the location information to generate path information; anda communication unit configured to provide the path information to the terminal device, whereinthe path is selected from among a plurality of paths based upon environmental information pertaining to the paths and the identified purpose for the trip,the environmental information is mapped to the path using an environmental information providing data structure which records the environmental information sensed around the location to correspond with global positioning system coordinates of the location,the environmental information comprises ambient air pollution levels describing concentrations of different particles, andwhether the ambient air pollution level is displayed is determined based on the identified purpose for the trip.

A path information providing method comprising:ncollecting environmental information of data sensed by a sensing device and information on a location at which the data is sensed;receiving a path request including a departure location and a destination from a terminal device;selecting a path, among a plurality of paths, based upon the received departure location and destination, environmental information pertaining to the paths, and a purpose for a trip identified by a user of the terminal device;determining a type of environmental information among the collected environmental information to be mapped to the path based upon the identified purpose for the trip;mapping the determined type of environmental information to the path based on the location information to produce path information; andproviding the path information to the terminal device,wherein the mapping of the determined type of environmental information comprises mapping the environmental information to the path using an environmental information providing data structure which records the environmental information sensed around the location to correspond with global positioning system coordinates of the location,wherein the environmental information comprises ambient air pollution levels describing concentrations of different particles, andwherein whether the ambient aft pollution level is displayed is determined based on the identified purpose for the trip.

A terminal device, which receives path information from a path information providing server, the terminal device comprising:na network interface unit configured to perform data transmission and receipt with the path information providing server; anda control unit configured to generate a path information request including information identifying the purpose for a trip, a departure location, and a destination according to a user input signal, transmit the generated path information request to the path information providing server and control the network interface unit to receive path information from the path information providing server; wherein:the path information includes mapping information in which relevant environmental information is mapped to a path between the departure location and destination,the environmental information mapped to the path is selected from a larger set of environmental information based upon the identified purpose for the trip,the path is selected from among a plurality of paths based upon environmental information pertaining to the paths and the identified purpose for the trip,the environmental information is mapped to the path using an environmental information providing data structure which records the environmental information around the location to correspond with global positioning system coordinates of the location,the environmental information comprises ambient air pollution levels describing concentrations of different particles, andwhether the ambient air pollution level is displayed is determined based on the identified purpose for the trip.
