1. An anomaly detection system for a transport service comprising: one or more processors; and one or more memory resources storing instructions that, when executed by the one or more processors, cause the anomaly detection system to: construct routine route profiles for users of the transport service by, for each of the users, (i) collecting historical route data, and (ii) identifying correlated route shapes in the historical route data; monitor a current route traveled by a respective one of the users; identify a matching routine route profile of the respective user; based on the matching routine route profile, determine a probable anomaly in the current route by performing a real-time probabilistic calculation and determining that a number of probability factors collectively exceed an anomaly threshold; and in response to determining the probable anomaly, perform one or more actions in accordance with a safety protocol, including transmitting a status query to a mobile device of the respective user or contacting an emergency authority to report the probable anomaly.
