Claim Text:
1. A method for routing a vehicle, comprising: receiving information describing an event that is to occur at a venue, the information comprising a first attendance estimate associated with the event; identifying one or more road segments where a degree of traffic congestion, above a specified threshold, is forecasted due to the event; generating a route for a vehicle from a starting location to an ending location based upon the degree of traffic congestion of the one or more road segments; displaying the route within a mapping field, of a road navigation user interface, depicting the one or more road segments; displaying an avoidance zone interface, visually overlaying a depiction of the venue and the one or more road segments, within the mapping field, the avoidance zone interface having a first size and encompassing a first area of the mapping field based upon the first attendance estimate, the avoidance zone interface comprising a first avoidance subzone interface and a second avoidance subzone interface different than the first avoidance subzone interface, the first avoidance subzone interface corresponding to a first portion of the one or more road segments where a first degree of traffic congestion, above the specified threshold and above a second threshold, is forecasted due to the event, the second avoidance subzone interface corresponding to a second portion of the one or more road segments where a second degree of traffic congestion, above the specified threshold but below the second threshold, is forecasted due to the event; responsive to receiving updated information, updating the degree of traffic congestion of the one or more road segments to identify an updated degree of traffic congestion for the one or more road segments, the updated information comprising a second attendance estimate associated with the event, the second attendance estimate different than the first attendance estimate; and modifying a visual property of the avoidance zone interface, in real-time during display of the road navigation user interface to a user, based upon the updated degree of traffic congestion, the avoidance zone interface having a second size and encompassing a second area of the mapping field after the modifying based upon the second attendance estimate, the second size different than the first size and the second area different than the first area.
