Modeling shoppers' time in stores in relation to their purchases

A method for analyzing shopper behavior within a store, the method comprising:

• for each of a plurality of a first group of shopper trips,
• detecting a wireless signal for a shopper proxy device adjacent an entrance to the store;
• detecting a wireless signal for the shopper proxy device adjacent an exit of the store;
• detecting a trip length for each shopper based on the detected presence of the detected wireless signal at the entrance and the exit of the store;
• calculating a first relationship between a number of shopper trips and trip length;
• for each of a plurality of a second group of shopper trips,
• receiving transaction data for a plurality of purchase transactions at the store, and transaction data for a plurality of items;
• calculating a second relationship between shopper trips and items purchased in the purchase transactions;
• determining a third relationship between items purchased and trip length based on the first and second relationships;
• detecting a current number of shoppers in the store;
• and
• deploying an in-store service in response to detecting that a current number of shoppers exceeds a first predetermined threshold.

A method of managing a queue length in a store comprising:

• detecting a trip length for each shopper based on a detected presence of a detected wireless signal at the entrance and the exit of the store;
• receiving transaction data for a plurality of purchase transactions at the store, and transaction data for a plurality of items;
• determining a probabilistic shopping behavior for the store based on the detected trip length and received transaction data;
• and
• deploying an in-store service responsive to a current number of shoppers in the store exceeding a predetermined threshold and the probabilistic shopping behavior for the store.
