What are primary and alternate drives?
When you set up an alert, you always define one primary drive that is your main route and the one we monitor for traffic conditions. Once you’ve defined the alert for the primary drive, you can add alternate drives to it. We don’t monitor the alternates for traffic conditions, but when we give you a alert on your primary we try to include summary information for the alternates. How this information is included varies depending on the type of alert. In desktop e-mail alerts we include Jam Factor summaries of the conditions on all of the alternates. In the mobile e-mail alerts, we do not include alternate information. In voice alerts you can ask for alternates during your call to quickly get the information about them.
