A method, computer system and computer program product for predicting traffic is provided. A processor determines a content of a first message posted to a social network. A processor determines that the content of the first message describes a first event. A processor determines an amount of predicted traffic to be caused by the first event. A processor determines a content of a second message posted to a social network. A processor determines that the content of the second message describes the first event. A processor adjusts the amount of predicted traffic to be caused by the first event based, at least in part, on the content of the first and second message, where the amount of predicted traffic to be caused by the first event is increased based, at least in part, on the first and second message describing the first event.
Please help me write a proper abstract based on the patent claims. CLAIM: 1. A method of predicting traffic, the method comprising: determining, by one or more processors, a content of a first message posted to a social network; determining, by the one or more processors, that the content of the first message describes a first event, wherein the first message indicates one or more of (i) a type of the first event, (ii) a location of the first event, and (iii) a time frame that first event will occur; determining, by the one or more processors, an amount of predicted traffic to be caused by the first event; determining, by the one or more processors, a content of a second message posted to a social network; determining, by the one or more processors, that the content of the second message describes the first event; adjusting, by the one or more processors, the amount of predicted traffic to be caused by the first event based, at least in part, on the content of the first and second message, wherein the amount of predicted traffic to be caused by the first event is increased based, at least in part, on the first and second message describing the first event; receiving, by the one or more processors, an observed amount of traffic caused by the first event; determining, by the one or more processors, a difference between (i) the amount of predicted traffic to be caused by the first event and (ii) the observed amount of traffic caused by the first event; in response to the difference being above a certain amount of traffic, adjusting, by the one or more processors, an amount of predicted traffic to be caused by a second event, wherein the second event occurs at a later time than the first event; determining, by the one or more processors, a content of a third message posted to a social network; determining, by the one or more processors, the content of the third message describes a third event; receiving, by the one or more processors, a location as a destination to for navigation; determining, by the one or more processors, a route from a current location to the destination; determining, by the one or more processors, a portion of the route intersects with a location of the first event; determining, by the one or more processors, a first alternative route which bypasses the portion of the route intersecting with the location of the first event; determining, by the one or more processors, a portion of the first alternative route intersects with a location of the first and third event; and determining, by the one or more processors, a second alternative route which bypasses the portion of the route intersecting with the location of the first event and the portion of the first alternative route intersecting with the location of the third event.
