Abstract

A rating is calculated that represents the traffic conditions of a specified driving route that includes at least one road. The driving route is specified by selecting an initial road, selecting a road entry point from which to get on the initial road, selecting a road exit point on which to get off the initial road, and specifying whether the road exit point is the end of the driving route. If the road exit point is not the end of the driving route, another road exit point is selected. The above-mentioned steps are then repeated until the road exit point is the end of the driving route. Traffic conditions are then obtained for that driving route and a rating is calculated based on the traffic conditions.

Claims

1. A computer-implemented method of calculating a rating that represents the traffic conditions of a specified driving route comprising:

(a) specifying a driving route, such that the route includes at least one road, wherein specifying the driving route comprises;

(i) selecting an initial road;

(ii) selecting a road entry point from which to get on the initial road;

(iii) selecting a road exit point on which to get off the initial road;

(iv) specifying whether the road exit point is the end of the driving route;

(v) selecting another road exit point if the road exit point is not the end of the driving route; and

(vi) repeating steps (iv)-(v) until the road exit point is the end of the driving route;

(b) obtaining the traffic conditions for that driving route; and

(c) calculating a rating based on the traffic conditions.

2. The method of claim 1 wherein the specified driving route is a keyroute, the keyroute being one or more road segments.

3. The method of claim 1 wherein the route includes a plurality of roads.

4. An article of manufacture for calculating a rating that represents the traffic conditions of a specified driving route, the article of manufacture comprising a computer-readable medium encoded with computer-executable instructions for performing a method comprising:

(a) specifying a driving route, such that the route includes at least one road, wherein specifying the driving route comprises;

(i) selecting an initial road;

(ii) selecting a road entry point from which to get on the initial road;

(iii) selecting a road exit point on which to get off the initial road;

(iv) specifying whether the road exit point is the end of the driving route;

(v) selecting another road exit point if the road exit point is not the end of the driving route; and

(vi) repeating steps (iv)-(v) until the road exit point is the end of the driving route;

(b) obtaining the traffic conditions for that driving route; and

(c) calculating a rating based on the traffic conditions.

5. The article of manufacture of claim 4 wherein the specified driving route is a keyroute, the keyroute being one or more road segments.

6. The article of manufacture of claim 4 wherein the route includes a plurality of roads.

7. A computer-implemented apparatus for calculating a rating that represents the traffic conditions of a specified driving route comprising:

(a) means for specifying a driving route, such that the route includes at least one road, wherein the means for specifying the driving route comprises;

(i) means for selecting an initial road;

(ii) means for selecting a road entry point from which to get on the initial road;

(iii) means for selecting a road exit point on which to get off the initial road;

(iv) means for specifying whether the road exit point is the end of the driving route;

(v) means for selecting another road exit point if the road exit point is not the end of the driving route; and

(vi) means for repeating steps (iv)-(v) until the road exit point is the end of the driving route;

(b) means for obtaining the traffic conditions for that driving route; and

(c) means for calculating a rating based on the traffic conditions.

8. The apparatus of claim 7 wherein the specified driving route is a keyroute, the keyroute being one or more road segments.

9. The apparatus of claim 7 wherein the route includes a plurality of roads.
