Using routing symbols to describe a driving maneuver
View Patent ↗Driving directions are presented where a maneuver in the driving directions includes a road symbol and an action symbol. A road symbol identifies the road involved in the particular maneuver, and an action symbol identifies an action to be performed to execute the particular maneuver. In one example, a road symbol, an action symbol and narrative text may be presented in displayed or printed driving directions. In another example, a road symbol and an action symbol may be used to describe a maneuver presented by an on-board or mobile navigation system when the vehicle in which the navigation system is present approaches the point at which the maneuver is to be taken. The road symbol and the action symbol may be presented with, or without, narrative driving directions.
1. A computer-implemented method, comprising:
obtaining information associated with a maneuver included within a route from an origin to a destination, the maneuver information including a road type and a turn angle associated with the maneuver;
determining, using a processor, a road symbol for the maneuver based on at least the road type and an action symbol for the maneuver based on at least the turn angle; and
generating an instruction to present the road symbol and the action symbol to a user, the presented road and action symbols describing the maneuver to the user.
2. The method of claim 1 , wherein the action symbol indicates at least one of a turn direction involved in the maneuver, a merge operation associated with the maneuver, or an identifier of an exit associated with the maneuver.
3. The method of claim 1 , wherein the road symbol includes a road number that identifies the road represented by the road symbol.
4. The method of claim 1 , wherein the road symbol comprises an interstate road symbol, the interstate road symbol corresponding to an interstate sign used to mark the interstate represented by the interstate road symbol.
5. The method of claim 1 , further comprising generating an instruction to present the road symbol in a position adjacent to the action symbol.
6. The method of claim 1 , wherein the determining comprises:
accessing a mapping symbol database comprising information identifying a plurality of road symbols and action symbols;
obtaining the road symbol from the mapping symbol database using at least the road type; and
obtaining the action symbol from the mapping symbol database using at least the turn angle.
7. The method of claim 1 , wherein the determining comprises determining the road symbol based on the road type and at least one of a road number, a road name, or a road direction associated with the maneuver.
8. An apparatus, comprising:
a storage device; and
at least one processor coupled to the storage device, wherein the storage device stores a program for controlling the at least one processor, and wherein the at least one processor, being operative with the program, is configured to:
obtain information associated with a maneuver included within a route from an origin to a destination, the maneuver information comprising a road type and a turn angle associated with the maneuver;
generate a road symbol for the maneuver based on at least the road type and an action symbol for the maneuver based on at least the turn angle; and
generate an instruction to present the road symbol and the action symbol to a user, the presented road symbol and action symbol describing the maneuver to the user.
9. The apparatus of claim 8 , further comprising a communication component capable of transmitting and receiving voice communications, the communication component being configured to receive the instruction and present the road symbol and the action symbol to the user.
10. The apparatus of claim 8 , wherein the action symbol indicates at least one of a turn direction involved in the maneuver, a merge operation associated with the maneuver, or an identifier of an exit associated with the maneuver.
11. The apparatus of claim 8 , wherein the road symbol includes a road number that identifies the road represented by the road symbol.
12. The apparatus of claim 8 , wherein the road symbol comprises an interstate road symbol, the interstate road symbol corresponding to an interstate sign used to mark the interstate represented by the interstate road symbol.
13. The apparatus of claim 8 , wherein the at least one processor is further configured to generate an instruction to present the road symbol in a position adjacent to the action symbol.
14. The apparatus of claim 8 , wherein the at least one processor is further configured to:
access a mapping symbol database including information identifying a plurality of road symbols and action symbols;
obtain the road symbol from the mapping symbol database using at least the road type; and
obtain the action symbol from the mapping symbol database using at least the turn angle.
15. The apparatus of claim 8 , wherein the at least one processor is further configured to determine the road symbol based on the road type and at least one of a road number, a road name, or a road direction associated with the maneuver.
16. A tangible, non-transitory computer-readable medium storing instructions that, when executed by at least one processor, cause the at least one processor to perform a method, comprising:
obtaining information associated with a maneuver included within a route from an origin to a destination, the maneuver information including a road type and a turn angle associated with the maneuver;
determining a road symbol for the maneuver based on at least the road type and an action symbol for the maneuver based on at least the turn angle; and
generating an instruction to present the road symbol and the action symbol to a user, the presented road symbol and action symbol describing the maneuver to the user.
17. The computer-readable medium of claim 16 , wherein the method further comprises generating an instruction to present the road symbol in a position adjacent to the action symbol.
18. The computer-readable medium of claim 16 , wherein the determining further comprises:
accessing a mapping symbol database including information identifying a plurality of road symbols and action symbols;
obtaining the road symbol from the mapping symbol database using at least the road type; and
obtaining the action symbol from the mapping symbol database using at least the turn angle.
