Disclosed is a method for sharply reducing diurnal breathing loss emissions from automotive evaporative emissions control systems by providing multiple layers, or stages, of adsorbents. Contextual information such as time of day and day of week, along with such findings as the observed velocities on different roads and the efficiency of trips is noted from the database of trips to inform a route generation component. The user input includes one or more declarative statements specifying conditional patterns based on attributes of diagram elements. The first controller is also configured to receive an indication of whether the operator has completed the training, and, when the indication indicates that the operator has completed the training, request, from the server, a confirmation that the operator has completed the training.
