1 Introduction
RSU2 is the next generation Road-side Unit (RSU) developed by Savari Inc. primarily for the
USDOT (United States Department of Transportation) Connected Vehicles program. It is the
latest addition to the StreetWAVE™ family of products. It is capable of transmitting signed or
unsigned MAP Data message, Signal Phase and Immediate Forward message, Store and
Repeat, and providing IPv6 connectivity to OBUs over a dedicated short-range communications
(DSRC) 5.9 Gigahertz (GHz) wireless networks using the following protocol stack and other
standards associated with DSRC for vehicular communications:
IEEE 802.11p
IEEE 1609-1 through 1609-4
J2735 (2016 version)
USDOT RSU 4.1 specification
StreetWAVE™ has a provisioning/test interface that can receive and load new versions of
software, new configurations and credentials, and instructions to perform logging functions and
download log messages to an external device. This device can be mounted on different
roadside locations (E.g.: traffic pole)
