THE EMTRAC SYSTEM Simple. Accurate. Reliable. Revolutionary!
The EMTRAC system tracks vehicle positions and
progress as they travel through their routes. As vehicles move along these
routes, they enter pre-defined detection zones and transmit data via secure
FHSS radio to appropriate wayside detectors and/or initiate an on-board
EMTRAC LRV and Streetcar Virtual Detection System for Surface and Subway
Improving mass transit in and around major cities is a
nationwide priority as most regions have plans to add or expand light
rail vehicle (LRV) and streetcar systems. Traditionally these systems
are expensive and cost prohibitive to design, install, operate, and
maintain. The high cost of adding and maintaining infrastructure using
traditional methods is forcing rail agencies to look for innovative ways
to accomplish their goals at economical prices.
Set your sights on a solution: the EMTRAC system.
EMTRAC system is an extremely powerful and reliable virtual loop
detection system that utilizes the technological advances of Global
Positioning Systems (GPS) along with dead reckoning to provide track
specific features in subways and on the surface that will reduce design,
installation, operating, and maintenance costs for non-vital signal
elements on LRV and streetcar systems.
Non-vital elements include, but are not limited to:
- Rail-worker safety - TWC (track warrant control) - Rail priority (rail transit signal priority and pre-emption) - AVL (automatic vehicle location) - Speed zone monitoring and alarms - Reverse running
EMTRAC system eliminates the need for embedded loops in the trackway
and reduces the need for other wayside detection equipment. The EMTRAC
system replaces at least 15 different components of traditional train
and wayside hardware. This is done by creating detection zones, which
are defined by GPS coordinates and allow system data to be sent only
when pre-defined conditions (such as position, speed, and direction) are
met. The potential cost savings is significant.
have many uses, can be placed anywhere, can be any size, can be used as
often as desired, and can be easily moved or changed based on current
needs. Detection zones can be used as an overlay to existing detection
methods and/or used as direct replacement of optical and inductive TWC
systems. The EMTRAC system has unmatched detection capabilities that
requires no costly loops or switches to install or maintain, and it
accurately reports vehicle positions in adverse weather conditions and
