1. A discretization system configured to receive vehicle event information that includes first non-discrete sensory data and first discrete quantitative data related to operation of a vehicle during a vehicle event, the discretization system comprising: one or more physical computer processors configured to: facilitate discretization of a portion of the first non-discrete sensory data; determine second discrete quantitative data based on the discretization of the portion of the first non-discrete sensory data; and determine third discrete quantitative data based on one or more of the first discrete quantitative data, the second discrete quantitative data, or the first non-discrete sensory data.
