An approach is provided for proactive booking of a shared vehicle. A routing platform determines that a user is leaving a location for a destination. The routing platform calculates a probability that the user will use a transport mode employing the shared vehicle for a route segment to the destination based on a context and a profile of the user. The routing platform initiates a creation of a proactive reservation of the shared vehicle based on determining that the probability meets or exceeds a threshold value. The proactive reservation is created without intervention of the user.
