The Los Angeles County Information Exchange Network Project Goals are:
Use An Open Architecture
The purpose of the IEN project is to establish a network for sharing information and control of the various traffic control systems in the region using a
common network backbone based on the Common Object Request Broker Architecture (CORBA). What is unique to the IEN is the fact that the primary focus of the system is
Intersection Traffic Control as opposed to freeway management. The system establishes a common system interface definition language (IDL), so that any traffic control system
can connect to the IEN.
Share Real-time Data
The IEN is also unique because it shares second-by-second real-time intersection data; most other regional
systems deal with slowly changing freeway data and Dynamic Message Signs, while the IEN was specifically designed to share real-time data to support real-time intersection
displays, section displays, and arterial coordination. Sharing information and control along the corridor is intended to improve coordination between systems along the
arterials and improve response management in the event of a problem with special events or incidents along the freeway or surface streets in the corridor.
Share Control and Monitoring
The system also allows smaller agencies to share limited control of their traffic control system to another agency for off-hours support. Thus, a single agency can serve as the after hours coordination center for
