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)

4 StreetWAVE™ Features

This chapter explains the salient features of the StreetWAVE™ roadside equipment. Following is the architecture diagram of StreetWAVE™. Each component is explained briefly in

the following sub-sections:

Figure 1: StreetWAVE Software Architecture Diagram

StreetWAVE™ features are explained briefly in the following sub-sections:

4.1 DSRC Radio Pair

Each StreetWAVE™ unit consists of two (2) integrated high power DSRC radios, which are exposed as the following two interfaces:

 Radio 1

 Radio 2

StreetWAVE™ radio configuration is very flexible. Any or both radios can be configured on any of the following channel modes:

 Alternating Channel Access  Continuous Channel Access

The following applications can be configured to use any of the two interfaces (Radio1 or Radio2):

 Immediate Forward  Store and Repeat  IPv6-provider  DSRC Message Forward  TCD

RSU2 User Guide

 RTCM  NTP

However, radio configuration between the above-mentioned applications should be consistent. You can operate multiple StreetWAVE™ units in a hub-and-spoke configuration in which the hub unit originates a message. It broadcasts those messages on its configured DSRC interface to OBUs as well as on Ethernet interface to the spoke StreetWAVE™ units in Savari ’s proprietary format. The spoke StreetWAVE™ units receive them and broadcast them on their DSRC interfaces, essentially working as DSRC repeaters. This configuration is useful at an intersection where no specific location has line of sight to all approaches to the intersection. The Hub unit does not have to be in the traffic controller cabinet. It can be one of the units on the pole if it has Ethernet connectivity to the cabinet.

4.2 IPv4 and IPv6 Networking

Each StreetWAVE™ unit consists of one Ethernet interface (eth0). StreetWAVE™ provides support for both IPv4 and IPv6 networking on all its interfaces (eth0, Radio 1, or Radio 2).

You can enable the following on all the three available interfaces:

 IPv4 and IPv6 addresses  IPv6 Router Advertisements

StreetWAVE™ can forward both IPv4 and IPv6 packets between its interfaces (Ethernet and DSRC) acting as a router. It also supports both IPv4 and IPv6 firewalls allowing the following:

 Source and destination IPv4 or IPv6 addresses  Port-based rules

4.3 Immediate Forward

StreetWAVE™ Immediate Forward application supports the forwarding feature in addition to the following features.

UDP Listener

4.3.1

StreetWAVE™ Immediate Forward application listens on configured UDP ports. If any message is received on these ports in the format specified in USDOT RSE requirements, it will sign the message using the 1609.2 protocol, if specified in the incoming message, and immediately transmits on the configured DSRC interface with the PSID and channel specified in the incoming message. Incoming messages could specify different priorities but it must specify the same transmit mode (TxMode) and transmit channel (TxChannel). This feature is used when an

RSU2 User Guide

intermediate device (TCID or a Battelle device) is sending periodic Immediate Forward messages to a StreetWAVE™.

UDP Streaming

4.3.2

The StreetWAVE™ can be configured to receive data from other StreetWAVE™ and stream it over DSRC. This allows the StreetWAVE™ to function as a repeater. In this setup, one StreetWAVE™ is configured as the Hub unit and all other StreetWAVE™ that are connected to it as Spoke units (that are not capable of independently transmitting Store and Repeat, Immediate Forward etc. and are depending on the Hub to provide this data). The Hub transmits the data over the air as well as to the Spoke unit typically over an Ethernet link. The Spoke unit, upon reception of the Hub’s packet, decodes and applies rules that are present in the packet, signs (if it is present in the packet) and forwards the packet over DSRC. The ability of the StreetWAVE™ to function in this manner can be used for streaming the packet data (in Savari proprietary format) from TMCs or back-end servers over the air. This arrangement could be useful in scenarios where a single StreetWAVE™ may not provide ample coverage for the geographic area of interest.

4.4 Store and Repeat

StreetWAVE™ supports transmission of Store and Repeat. The Store and Repeat application, which runs on the StreetWAVE™ unit, transmits on the configured channel over the Radio 1 (default configuration) interface.

Store and Repeat are configured in a data store inside the StreetWAVE™. The data store supports up to 100 Store and Repeat. The Store and Repeat are stored in the form of Active message files. Each file contains the transmissions parameters and the actual data of the Store and Repeat message. Each Store and Repeat message can be scheduled differently. The active message files follow the USDOT RSE 4.1 Specification.

4.4.1

StreetWAVE™ supports the USDOT Active Message Configuration file format for configuring active Store and Repeat messages.

Active Store and Repeat Message Configuration

US DOT Active Message Configuration file format

This format is defined in section US DOT RSU 4.1 requirements. Each Store and Repeat active message should be defined in a separate file.
