In congested cities, it can be difficult for an ambulance or other emergency vehicle to reach a location from which the vehicle is requested. Delay in the arrival of such vehicles is a waste of crucial time due to the emergency nature of the task for such vehicles. This disclosure describes techniques to address the above deficiencies through an alert notification system in a navigation or maps application (app). Vehicles along the route of the emergency vehicle are identified automatically, e.g., based on location information shared from such vehicles via their navigation app. Appropriate notifications are generated and sent to such vehicles. The notifications can include information that an emergency vehicle is approaching and optionally, a suggested action for the vehicle. Vehicles that cannot directly receive push notifications can be notified through vehicle-to-vehicle communication or via on-board sensors.
