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

functions: |
| — |
Controls and supervises Variable Message Signs (VMS). |
— |
Warns
approaching traffic about queues. |
| — |
Monitors
other equipment. |
— |
Collects
and stores traffic data. |
| — |
Adapts maximum speed to current traffic and weather situation. |
|
|
| The
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. |
|
Especially developed to meet the high requirements of the
European EN standards, the SMC performs a number of functions
including: |
| • |
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. |
| • |
Communication
with “Central Control Systems” via TCP/IP. |
| • |
Support
of different configurable algorithms. |
| • |
Convenient confi guration, monitoring and control via the
integrated web-server. |
|
| 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 confi guration 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 +85°C.
|
| For
standalone 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.
