System and method for providing origin and destination guide information

1. A system for providing origin and destination guide information to a vehicle terminal connected through a wireless network, the system comprising:

an origin selector for selecting an origin link that is a road adjacent to an origin according to a direction and a current position of the vehicle terminal;

a destination selector for selecting a destination link that is a road adjacent to a destination according to a position and a type of the destination;

a path generator for generating a path from the origin link to the destination link based on the selected origin link, the selected destination link, real-time traffic information, and map information;

a guide information generator for generating guide information having at least one of an adjacent map of the generated path and speech information on the path; and

a guide information provider for providing the generated guide information to the vehicle terminal,

wherein the destination selector selects at least one destination link provided with a predetermined range of the destination coordinate and searches destination links again to select a desired destination link when the destination link to be selected is one of a superhighway, an urban expressway, an overpass, and a subway, and

the path generator generates paths for the at least one destination link and determines an optimized path from among the generated paths.

2. A system for providing origin and destination guide information to a vehicle terminal connected through a wireless network, the system comprising:

an origin selector for selecting an origin link that is a road adjacent to an origin according to a direction and a current position of the vehicle terminal;

a destination selector for selecting a destination link that is a road adjacent to a destination according to a position and a type of the destination;

a path generator for generating a path from the origin link to the destination link based on the selected origin link, the selected destination link, real-time traffic information, and map information;

a guide information generator for generating guide information having at least one of an adjacent map of the generated path and speech information on the path; and

a guide information provider for providing the generated guide information to the vehicle terminal,

wherein the origin selector controls a user to select the origin link from among provided roads when at least two roads of a superhighway, an urban expressway, an overpass, and a subway are provided together within a predetermined range of the origin, and

wherein the destination selector selects at least two approaches as destination links when the destination has the at least two approaches, and

the path generator generates paths for the at least two selected destination links and determines an optimized path from among the generated paths.

3. The system of claim 2 , wherein the destination selector searches destination links again to select a desired destination link when the destination link to be selected is one of a superhighway, an urban expressway, an overpass, and a subway.

4. A method for providing origin and destination guide information to a vehicle terminal connected through a wireless network, the method comprising:

a) selecting an origin link that is a road near an origin according to a direction and a current position of the vehicle terminal;

b) selecting a destination link that is a road near a destination in consideration of a position and a type of the destination;

c) generating a path from the origin link to the destination link based on the selected origin link, the selected destination link, real-time traffic information, and map link information; and

d) generating guide information having at least one of an adjacent map of the generated path and speech information, and providing the generated guide information to the vehicle terminal,

wherein b) comprises: selecting at least one link provided in a predetermined range of the destination coordinate to be a candidate destination link, and searching destination link again to select a desired destination link when the destination link to be selected is one of a superhighway, an urban expressway, an overpass, and a subway, and

c) comprises: generating a respective path of the selected at least one candidate destination link and determining an optimized path from among the generated paths.

5. A method for providing origin and destination guide information to a vehicle terminal connected through a wireless network, the method comprising:

a) selecting an origin link that is a road near an origin according to a direction and a current position of the vehicle terminal;

b) selecting a destination link that is a road near a destination in consideration of a position and a type of the destination;

c) generating a path from the origin link to the destination link based on the selected origin link, the selected destination link, real-time traffic information, and map link information; and

d) generating guide information having at least one of an adjacent map of the generated path and speech information, and providing the generated guide information to the vehicle terminal,

wherein a) comprises: controlling a user to select a road type of the origin link when at least two of a superhighway, an urban expressway, an overpass, and a subway are provided together within a predetermined range of the origin,

wherein b) comprises: selecting an approach to be a candidate destination link when the destination includes at least one approach, and

wherein c) comprises: generating a respective path of the selected at least one candidate destination link; and determining an optimized path from among the generated paths.

6. The method of claim 5 , wherein b) comprises: searching destination links again to select a desired destination link when the destination link to be selected is one of a superhighway, an urban expressway, an overpass, and a subway.
