Road Side Equipment (RSE)
Deployment Rate
RSE installation
for all RSEs initiated
•RSE is equipment on road or at traffic signal
that enables information to be passed to OBEs.
•Deployment assumes no readily available federal
funding for RSEs.
•RSEs are needed to enable DSRC communication.
AERIS applications that are not signal based do not rely
on RSEs; rather they utilize cellular
communication.
•RSE number based on freeway road miles and
number of traffic signals.
•At full deployment, 30% of urban traffic signals
will have an RSE.
•At full deployment, urban and rural freeways
will have 2 RSEs every 10 miles (one for each direction).

Started with Volpe Center
Vehicle-Infrastructure Integration (VII) Initiative Benefit-Cost Analysis Version 2.3 (Draft) assumptions; based on internal AERIS team meeting, made RSE deployment more conservative ; based on JPO June 20th brief further
revised down deployment.
