Telematics and external data relating to the real-time driving of a driver of a taxi vehicle may be collected and used to calculate a driving score. A telematics device installed in the taxi vehicle may collect vehicle data, trip data, and passenger data from one or more sensors. A computing device in communication with the telematics device may calculate a driving score for the taxi vehicle during a trip based on a type of vehicle, a type of trip, a number of miles driven during the trip, a duration of the trip, a number of passengers in the taxi vehicle during the trip, and a type of the passengers in the taxi vehicle during the trip. As one example, the driving score may be provided to an employer of a driver of the taxi vehicle.
