SMC - SWARCO Motorway Controller

SMC: monitoring and guiding the traffic - minimizing accident risks

Product-info as PDF

Ever increasing traffic volumes require innovative methods for monitoring and controlling interurban traffic. The SWARCO Motorway Controller (SMC) is designed to minimize accident risks by monitoring the traffic flow and automatically closing lanes, reducing speed, and rerouting traffic when an incident is detected.

SMC: SMALL AND POWERFUL

SMC is a small but powerful outstation unit designed for simple motorway applications, tunnel schemes, variable speed projects and similar traffic control and monitoring tasks.

The unit is designed to be easy to use and quick and simple to install. It has been especially developed to meet the high requirements of the European EN standards.

  • Controls and supervises Variable Message Signs (VMS).
  • Monitors other equipment.
  • Adapts maximum speed to current traffic and weather situation.
  • Warns approaching traffic about queues.
  • Collects and stores traffic data.
  • Collection and processing of data from different types of traffic detectors.
  • Autonomous control and supervision of signs from SWARCO FUTURIT and other message sign suppliers.
  • Support of different configurable algorithms.
  • Communication with “Central Control Systems” via TCP/IP.
  • Convenient configuration via web-server.

SMC OUTSTATION

For easy maintenance, the SMC outstation is a completely self-contained electronic unit based on a standard 19 inch rack. All modules can be exchanged on-site and the unit is easily expanded by inserting new modules. All configuration is done through software eliminating the need for unwieldy wire wraps or easily lost pcb jumpers. Thanks to an integrated battery-backed internal real time clock, the SMC can perform both time based control actions and event based control actions. Outputs can be processed based on any combination of input values or specific detection system functions such as AID (automatic incident detection), wrong-way driver detection, height detection, WIM (weight in motion) and more. The SMC outstation software runs on a LINUX operating system making it suitable for use 24 hours a day, 7 days a week and the hardware platform is suitable for installation in the harsh roadside environment. The unit is delivered with extended temperature range from -40°C to +55°C. For stand-alone applications as well as for integration into larger systems, the SMC outstation offers the possibility of remote configuration, detailed system monitoring and simple control of complex connected devices via an enhanced, password protected web-based user interface.
