Key Features
J1-LED The J1-LED MIDAS Outstation Intelligent Vehicle Detector is a reliable and accurate vehicle detection system with low maintenance costs.
The MIDAS collects, stores and reports on multi-lane traffic data comprising of individual vehicle data events or average flow data relating to traffic volume, speed, length category, vehicle headway and percentage occupancy. It can monitor 28 loops (14 lanes) at vehicle speeds up to 125mph. An external host computer can access information by interrogating the processor via the various communications options available on the front panel. Remote access via our easy-to-use web browser interface allows rapid configuration, real-time incident detection, real-time viewing of traffic and host communication data, extensive fault diagnostics and logs. The MIDAS also supports the MIDAS NMCS2 communications protocol for configuration and vehicle data.

The MIDAS uses the already proven TD664 detector incorporating Automatic Frequency Selection (AFS). The AFS circuitry on each 4-channel card evaluates 21 possible frequency shift selections and automatically chooses the best frequency setting on start-up.
The MIDAS logs every event that occurs and classifies it as a vehicle event, communications event, fault, alarm, debug, info, or critical issue. This data is available on a real time Live View via the web interface. It is also written to file and can be stored in onboard Flash memory, to an external USB drive, or automatically uploaded to an FTP server.
Traffic data comprises average data calculated over pre-determined intervals and includes vehicle count, speed, volume, headway, and occupancy. Optionally individual vehicle reporting can be selected which provides a record of every vehicle showing its lane number, speed, length, and headway. Loops can be configured as stand- alone loops or paired into lanes to suit the application and required data.
The MIDAS has an Ethernet port for Upstream connectivity using the MIDAS NMCS2 protocol. A second Ethernet port can be used for on-site web browser access, or an Engineers Terminal. The web browser interface allows equipment interrogation, verification and setup of all operating parameters, real-time monitoring of traffic data and communications, and viewing and downloading of traffic data and logs.
Three serial ports are provided to support the MIDAS Transponder connection, the Outstation Auxiliary Link, and the Engineer’s Terminal
