Portable traffic management systems (PTMS), also called Moveable Event Management Systems (MEMS), consist of easily portable traffic control and management devices.  PTMS components provide surveillance, traffic control, traffic management, and advisory functions for special events such as concerts or sporting events which generate intense traffic and parking demands over a relatively short, but predictable period of time.  PTMS components typically include: 

• A mobile command post, such as a van, controlling the PTMS components and receiving the data from the other components;
• Portable closed circuit video cameras mounted on top of collapsible poles on small wheeled trailer units for surveillance of key interchanges and congestion locations;
• Portable (trailer-mounted) variable message signs;
• Low Power highway advisory radio for traveler information; and
• Portable traffic signals for safe access and egress control of parking lots.

The function of PTMS is to keep motorists informed of congestion, available parking locations, alternate routes, or any other information which would minimize delays associated with arriving at, or leaving the special event.  Since the event is planned and the traffic arrival and departure times can be estimated, the compliment of PTMS devices are deployed prior to a special event according to a pre-determined, approved plan. 

• Ease of implementation, with a two to three hour set up time
• Increased traffic flow and speeds
• Reduced congestion
• Reduced time for traffic to exit event by as much as 50 percent
• Notable system reliance and use
