The objective of this project was to present an assessment of how social media is used to support the management of traffic operations during non-routine events. To accomplish this, the authors reviewed literature related to social media use for transportation, and for disasters and crises. Further, the team reviewed social media sites and data provided by various transportation agencies, in particular the messages related to traffic and non-routine events. Based on the key findings, recommendations for transportation agencies are made to help transportation agencies better use social media for non-routine traffic events.
