In previous work of future congestion prediction using transit search logs, whether target station will get crowded on target time or not is predictable, but we cannot specify the cause of irregular congestion. In order to specify the irregular congestion cause, we analyzed posts containing information on future events from SNS. By combining congestion prediction information from the transit search log and event information from SNS, it was possible to extract the cause of congestion accurately.
