Sensor-based customer arrival detection

A system comprising:

• one or more processors;
• memory;
• and
• one or more computer-executable instructions stored in the memory and executable by the one or more processors to perform operations comprising:
• receiving, via a mobile application that resides on a first device of a customer and that is associated with a service provider, an order for one or more food items, the order identifying a physical store location at which the customer is to pick up the one or more food items;
• receiving, from the first device and while the customer is in transit to the physical store location, sensor data, the sensor data being obtained by one or more sensors of the first device and including at least one of location data, velocity data, or acceleration data;
• receiving, from a second device associated with the physical store location, an indication that the customer was located at the physical store location and a first time that corresponds to the indication;
• determining, based on the sensor data, multiple stop events while the customer is in transit to the physical store location, each stop event of the multiple stop events indicating a location and a time at which the first device moved less than a threshold amount for a predetermined amount of time;
• identifying, from the multiple stop events, a stop event representative of an arrival of the customer at a designated item pick-up area at the physical store location, the stop event being most proximate in time to the first time as compared to other stop events of the multiple stop events;
• determining a second time associated with the stop event;
• and
• estimating a wait time of the customer between the arrival of the customer at the physical store location and the indication by determining a difference between the first time and the second time.
