Description: | Portable (and often trailer-mounted) dynamic message signs are used to alter traffic patterns near work zones and to provide traffic management for sporting events, natural disasters, and other temporary changes in normal traffic patterns. The messages displayed on the sign can be programmed locally on the unit's control panel or remotely via computer or phone on units equipped with a cellular modem. For example, the city of Hilliard uses portable DMS primarily for workzone management purposes. The City does not own/operate any dynamic portable message signs. The city uses them in some of their construction projects. These signs are owned & operated by the contractor - not the City. The city of Upper Arlington uses portable DMS primarily for workzone management purposes. OSU Transportation and Parking Division owns a total of 4 portable DMS to provide work zone information. |
