Abstract

A computer-implemented method is provided for displaying on a graphical map traffic flow data representing traffic conditions on a road system. The graphical map includes one or more keyroutes, each keyroute being defined by one or more contiguous road segments. Congestion status of the one or more keyroutes are displayed on the graphical map. The congestion status is defined by partitioning the keyroute into one or more congestion segments, each congestion segment being defined in terms of a percentage range of the keyroute from the start of the keyroute. Each congestion segment has a congestion status. Also, a plurality of identification objects are shown at fixed positions in the graphical map and a plurality of different views of the graphical map are defined. Each identification object is coded to be either displayed or not displayed for each of the different views. Also, for a selected keyroute, a single display screen displays keyroute identifying information, and the real-time status of the keyroute, wherein the status is continuously updated on the single display screen.

Claims

1. A computer-implemented method of displaying on a graphical map traffic flow data representing traffic conditions on a road system, the graphical map including one or more keyroutes, each keyroute being defined by one or more contiguous road segments, the method comprising:

(a) creating a graphical map of the road system including the one or more keyroutes;

(b) determining congestion status of the one or more keyroutes on the graphical map, the congestion status corresponding to traffic flow data associated with the one or more segments of each respective keyroute, wherein the congestion status is defined by partitioning the keyroute into one or more congestion segments, each congestion segment being defined in terms of a percentage range of the keyroute from the start of the keyroute, each congestion segment having a congestion status; and

(c) displaying on the graphical map of the road system traffic flow data showing the congestion status of the one or more keyroutes.

2. The method of claim 1 wherein the graphical map of the road system is a 2D view, and each keyroute is animated to reflect its respective status by simulating different vehicle speeds that are representative of actual vehicle speeds.

3. The method of claim 1 wherein the graphical map of the road system is a 3D view, and each keyroute is animated to reflect its respective status by simulating different vehicle speeds that are representative of actual vehicle speeds.

4. A computer-implemented method of displaying traffic flow data on a graphical map of a road system, the graphical map including one or more segments, the traffic flow data representing traffic conditions on a road system, the method comprising:

(a) defining a plurality of identification objects to be shown at fixed positions in the graphical map and defining a plurality of different views of the graphical map, each identification object being coded to be either displayed or not displayed for each of the different views;

(b) determining a status of each segment on the graphical map, the status corresponding to the traffic flow data associated with that segment;

(c) selecting a view of the graphical map, the selected view determining which identification objects will appear in the graphical map;

(d) creating an animated traffic flow map of the road system by combining (i) the graphical map having the corresponding identification objects, and (ii) the status of each segment.

5. The method of claim 4 wherein the identification objects include road shields.

6. The method of claim 4 wherein the identification objects include geographic labels.

7. The method of claim 4 wherein the identification objects include secondary roads.

8. The method of claim 4 wherein at least some of the different views are predefined zoom levels.

9. A computer-implemented method of displaying traffic flow data, the traffic flow data representing real-time traffic conditions of one or more keyroutes on a road system, each keyroute being defined by one or more contiguous road segments, the method comprising:

(a) selecting one or more keyroutes;

(b) determining the real-time status of each keyroute, the real-time status corresponding to the traffic flow data associated with that keyroute; and

(c) displaying on a single display screen for each selected keyroute

(i) keyroute identifying information, and

(ii) the real-time status of the keyroute, the status being continuously updated on the single display screen.

10. The method of claim 9 wherein the traffic flow data represents average vehicle speeds along the keyroute.

11. The method of claim 9 wherein the traffic flow data represents average travel time along the keyroute.

12. The method of claim 9 wherein the traffic flow data represents average delay time along the keyroute.

13. The method of claim 9 wherein the keyroute identifying information includes a roadway'"'"'s name and/or route shield.

14. The method of claim 9 further comprising:

(d) automatically adjusting the size of the displayed information on the single display screen for each keyroute based on the number of selected keyroutes, wherein a greater number of selected keyroutes causes the size of the displayed information for each keyroute to be decreased.
