Systems Engineering / Integration

Our firm is well known as systems integration specialists and for our work in systems engineering.  The experience of our staff includes design, construction and operational experience and covers all transit subsystems and disciplines, including Communications, Signals, Street Traffic Controllers, Overhead Contact Systems, Power Rail/Third Rail/Contact Rail, Traction Power Substations, System-wide Electrical & Ductbanks, Ticket Vending Equipment/Automated Fare Collection, Computer Aided Dispatch/Automatic Vehicle Location (CAD/AVL), Stations and Station equipment, Parking, Maintenance/Control Facilities, Trackwork/Guideways and Vehicles.  This experience makes our design and implementation of transit systems better, because we understand all subsystems, and the interfaces between subsystems.  For every design we work on, we use a systems engineering approach to evaluate systems interfaces between subsystems and resolve these issues in the individual design packages.  Our systems engineering and integration experience includes SYSTEMS ENGINEERING APPROACH and SYSTEMS INTEGRATION.
