One or more techniques and/or systems are provided for routing a user between events using an itinerary. An event source (e.g., electronic calendar) may be assessed to identify event information (e.g., event locations) for events (e.g., meetings). The event information may be evaluated to determine a schedule of events. Routes between events within the schedule may be identified to determine route information (e.g., predicted travel times) for the routes. The event information and the route information may be evaluated to generate an itinerary of events. In an example, a constraint may be identified (e.g., a traffic accident along a route). The constraint may be evaluated to determine an impact (e.g., a user arriving to the meeting event late) of the constraint on the itinerary. Responsive to the impact exceeding an adjustment threshold, the itinerary may be adjusted (e.g., modifying a route between one or more events to avoid the accident).
