5. The method of claim 4, wherein the third possible street set contains no streets and wherein step (G) is performed by the further substeps of determining which street from within the second possible street set is closest to the placement of the vehicle and defining the street where the vehicle is located as the closest street from within the second possible street set.

6. The method of claim 4, wherein the third possible street set contains no streets, the second possible street set contains no streets and wherein step (G) is performed by determining which street from within the first possible street set is closest to the vehicle location and defining the street where the vehicle is located as the closest street from within the first possible street set.

7. The method of claim 4, wherein the first possible street set contains no streets and step (G) is performed by the further substep of determining which known street is closest to the placement of the vehicle and defining the street where the vehicle is located as the closest street.

8. The method of claim 3, wherein step (G) is performed by the further substeps of determining which street from within the second possible street set is closest to the placement of the vehicle and defining the street where the vehicle is located as the closest street from within the second possible street set.

9. The method of claim 3, wherein the preselected distance is 100 meters.

10. The method of claim 1, wherein the textual description of the vehicle location further includes at least one street that intersects with the street where the vehicle is located and wherein step (G) is performed by the substeps of determining the street where the vehicle is located and determining whether any known street has a portion that intersects with the street where the vehicle is located by searching along the street where the vehicle is located from the vehicle location in a direction corresponding to the vehicle direction of travel until an intersecting street is found.

11. The method of claim 10, wherein two intersecting streets are included in the textual description and a second intersecting street is determined by searching along the street where the vehicle is located from the vehicle location in a direction opposite from the vehicle direction of travel until the second intersecting street is found, such that the vehicle is located between the two intersecting streets.

12. The method of claim 11, wherein the textual description includes an approximate distance between the vehicle and the first and second intersecting streets, respectively and an orientation of the vehicle relative to the first and second intersecting streets.

13. The method of claim 11, wherein step (G) is performed using a digital mapping database.

14. The method of claim 10, wherein the textual description further includes a street address that is near the vehicle on the street where the vehicle is located, a name of a city, a name of a county and a name of a state where the vehicle is located.

15. The method of claim 1 further including the step of determining a street address to which the vehicle is closest, wherein the textual description indicates the street address.

16. The method of claim 1 further including the step of determining the street on which the vehicle is located automatically by a computer.

17. The method of claim 1 wherein the textual description can be read to dispatch assistance and sufficiently indicate the location of the vehicle.

18. A method of providing vehicle location information, comprising the steps of:

(A) generating an assistance request signal from the vehicle;
