Predicting realistic time of arrival for queue priority adjustment

A computer system, comprising:

• a processor;
• a memory device coupled to the processor;
• and
• a computer-readable storage device coupled to the processor, wherein the storage device contains program code executable by the processor via the memory device to implement a method for predicting a realistic time of arrival for performing a queue priority adjustment, the method comprising:
• determining, by a processor of a computing system, an estimated initial arrival time of a first user and a second user to a destination, the estimated initial arrival time being used to establish a queue priority of the first user and a queue priority of the second user, in a queue priority database, the queue priority of the first user being higher than the queue priority of the second user;
• tracking, by the processor, a current location of the first user and a current location of the second user, during transit to the destination;
• predicting, by the processor, a route to be taken to arrive at the destination from the current location of the first user and the current location of the second user, respectively;
• detecting, by the processor, a schedule-altering event of the first user by analyzing:
• (i) the predicted route of the first user, or (ii) a current state of a vehicle;
• and
• reprioritizing, by the processor, the queue priority database, in response to calculating an updated queue priority of the first user that is lower than the queue priority of the second user, based on the detection of the schedule-altering event of the first user.

A computer program product, comprising a computer-readable hardware storage device storing a computer-readable program code, the computer-readable program code comprising an algorithm that when executed by a computer processor of a computing system implements a method for predicting a realistic time of arrival for performing a queue priority adjustment, the method comprising:

• determining, by a processor of a computing system, an estimated initial arrival time of a first user and a second user to a destination, the estimated initial arrival time being used to establish a queue priority of the first user and a queue priority of the second user, in a queue priority database, the queue priority of the first user being higher than the queue priority of the second user;
• tracking, by the processor, a current location of the first user and a current location of the second user, during transit to the destination;
• predicting, by the processor, a route to be taken to arrive at the destination from the current location of the first user and the current location of the second user, respectively;
• detecting, by the processor, a schedule-altering event of the first user by analyzing:
• (i) the predicted route of the first user, or (ii) a current state of a vehicle;
• and
• reprioritizing, by the processor, the queue priority database, in response to calculating an updated queue priority of the first user that is lower than the queue priority of the second user, based on the detection of the schedule-altering event of the first user.
