Abstract

A rating is calculated that represents the traffic conditions of a specified driving route. A driving route is specified that includes a plurality of different roads. The traffic conditions for each of the different roads of the driving route are obtained. A rating is then calculated for the driving route that is based on the traffic conditions for each of the different roads of the driving route.

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 that includes a plurality of different roads;

(b) obtaining the traffic conditions for each of the different roads of the driving route; and

(c) calculating a rating for the driving route that is based on the traffic conditions for each of the different roads of the driving route.

2. The method of claim 1 wherein step (a) is performed by:

(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.

3. The method of claim 2 wherein steps (a)(i)-(a)(vi) are performed via a user interface display screen.

4. The method of claim 1 wherein step (c) is performed by:

(i) calculating the free flow travel time for the specified route,

(ii) calculating the total delay along the specified route,

(iii) summing the free flow travel time and the total delay to obtain the total estimated travel time,

(iv) calculating a delay multiple by dividing the total travel time by the free flow travel time, and

(v) calculating the rating based on the delay multiple.

5. The method of claim 1 wherein any road closure along the specified driving route automatically creates a rating of 10.

6. The method of claim 1 further comprising:

(d) displaying the rating on a web page.

7. 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 that includes a plurality of different roads;

(b) obtaining the traffic conditions for each of the different roads of the driving route; and

(c) calculating a rating for the driving route that is based on the traffic conditions for each of the different roads of the driving route.

8. The article of manufacture of claim 7 wherein step (a) is performed by:

(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.

9. The article of manufacture of claim 8 wherein steps (a)(i)-(a)(vi) are performed via a user interface display screen.

10. The article of manufacture of claim 7 wherein step (c) further comprises:

(i) calculating the free flow travel time for the specified route,

(ii) calculating the total delay along the specified route,

(iii) summing the free flow travel time and the total delay to obtain the total estimated travel time,

(iv) calculating a delay multiple by dividing the total travel time by the free flow travel time, and

(v) calculating the rating based on the delay multiple.

11. The article of manufacture of claim 7 wherein any road closure along the specified driving route automatically creates a rating of 10.

12. The article of manufacture of claim 7 further comprising:

(d) displaying the rating on a web page.

13. 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 that includes a plurality of different roads;

(b) means for obtaining the traffic conditions for each of the different roads of the driving route; and

(c) means for calculating a rating for the driving route that is based on the traffic conditions for each of the different roads of the driving route.

14. The apparatus of claim 13 wherein the means for specifying a driving route includes:

(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 the specifying of whether the road exit point is the end of the driving route and the selecting of another road exit point if the road exit point is not the end of the driving route until the road exit point is the end of the driving route.

15. The apparatus of claim 14 wherein the means (a)(i)-(a)(vi) includes a user interface display screen.

16. The apparatus of claim 13 wherein the means for calculating a rating includes:

(i) means for calculating the free flow travel time for the specified route,

(ii) means for calculating the total delay along the specified route,

(iii) means for summing the free flow travel time and the total delay to obtain the total estimated travel time,

(iv) means for calculating a delay multiple by dividing the total travel time by the free flow travel time, and

(v) means for calculating the rating based on the delay multiple.

17. The apparatus of claim 13 wherein any road closure along the specified driving route automatically creates a rating of 10.

18. The apparatus of claim 13 further comprising:

(d) means for displaying the rating on a web page.
