When problems directly affect your passengers, managing those incidents is critical to providing good service. Take this situation for example: snow coats the streets on a cold winter morning. An accident causes a road closure on a street used for multiple busy routes. The schedule is already complete, and buses are in service. This situation, and ones like it, can become a logistical headache, or it can be a “problem solved” when mitigated with an ad hoc Computer-Aided Service Restoration (CASR) measure.
