3. The method of claim 2, wherein the end location label for each of the plurality of potential destinations is rendered such that the end location label does not intersect road labels rendered based on the road style.

4. The method of claim 3, wherein the end location label is favored over the road labels such that intersecting road labels that cannot be repositioned to satisfy the multiple route style are not rendered.

5. The method of claim 1, wherein the plurality of routes intersect one or more route roads, wherein the one or more route roads are rendered with an emphasized font based on the multiple route style, and wherein other roads are rendered with an understated font based on the road style.

6. The method of claim 1, wherein the multiple route style is generated based on the plurality of routes and the road style.

7. A method of visual disambiguation for directions queries, the method comprising:

receiving a map search request comprising a start location and a search term;

performing by a plurality of processors a spatial search to identify a plurality of potential destinations that are each within a threshold distance of the start location and associated with the search term;

generating by the plurality of processors a plurality of routes, each of the plurality of routes describing a route from the start location to one of the plurality of potential destinations;

obtaining a road style for rendering roads in a map extent that encompasses the plurality of routes; and

sending the plurality of routes and the road style to a user device, the user device simultaneously displaying the plurality of routes based on a multiple route style that comprises the road style.

8. The method of claim 7, wherein each of the plurality of routes comprises a travel time for the route from the start location to one of the plurality of potential destinations, wherein the travel time for each of the plurality of routes is rendered as a travel time label based on the multiple route style.

9. The method of claim 7, wherein the start location has a start description that is rendered as a start location label and each of the plurality of potential destination has an end description that is rendered as an end location label based on the multiple route style.

10. The method of claim 8, further comprising rendering road labels based on the road style, wherein the multiple route style specifies that the end location label for each of the plurality of potential destinations cannot intersect the road labels.

11. The method of claim 10, wherein the end location label is favored over the road labels such that intersecting road labels that cannot be repositioned to satisfy the multiple route style are not rendered.

12. The method of claim 7, wherein the plurality of routes intersect one or more route roads, wherein the one or more route roads are rendered with an emphasized font based on the multiple route style, and wherein other roads are rendered with an understated font based on the road style.

13. The method of claim 7, further comprising:

receiving a user selection of a selected route of the plurality of routes; and

generating a route map for the selected route, the route map being displayed in a navigation display of the user device.

14. A system, comprising:

a plurality of memories;

a plurality of processors, each operatively connected to at least one of the plurality of memories;

a user device interface stored on the plurality of memories, the user device interface being executed by the plurality of processors to;

receive a map search request comprising a start location and a search term from a user device; and

send a plurality of routes and a road style to the user device, the user device simultaneously displaying the plurality of routes based on a multiple route style that comprises the road style;

a mapping module stored on the plurality of memories, the mapping module being executed by the plurality of processors to;

perform a spatial search to identify a plurality of potential destinations that are each within a threshold distance of the start location and associated with the search term;
