Location: Seminole County LabVendor: CiscoTest completed: V2I, V2VField Controller: Agnostic

Cisco’s devices were set-up and tested at the Seminole County Lab – using Commsignia’s RSU, Cohda’s OBU, and the Quanergy LiDAR device. The lab set-up mimicked the SR 50 field installations. Testing was to include the following applications:

SPaT MAP BSM EVP TSP TIM

EVP and TSP were not available for testing. This will be Phase 2 of Cisco’s deployment and demonstration. Cisco and ESRI are currently developing a microservice using a GIS basemap to achieve TSP and EVP (assigning preemption to the correct phase and lane).

Cisco uses a GUI to interact with the CV Equipment, software, and the end user. The Kinetic Edge and Fog Processing Module allows the user to perform a variety of tasks as well as manage the CV Equipment. The EFM Dataflow Editor allows users to customize the CV Messages and “breaks” down the message per the J2735 standards.

Cisco was successful in demonstrating integration from their Kinetic Edge and Fog Processing Module to all the controllers for SPaT Messages in the lab to include the following controllers:

o Siemenso Econoliteo Intelighto TrafficWare

As seen in the above image, Cisco’s software was able to display the SPaT messages from the controllers along with the JSON parsing. Along with demonstrating the SPaT in the lab, Cisco demonstrated development of TIM messages via their software and broadcasted the message from the Cisco Commsignia RSU. The message was received by the Cohda OBU as well as the D5 Commsignia OBU.

Cisco demonstrated the LiDAR technology in the Seminole County Lab. The LiDAR (Quanergy) would track movement, assigning an object and assigning GPS coordinates to that object. By assigning the object a GPS, Cisco’s software can then create a Pedestrian Safety Alert (PSA) and send it to the RSU for broadcasting. Cisco used a “Hardened and Rugged” computer that is rail-rated for vibration. This computer housed the software needed to accomplish the outputs needed for the PSA.The Pedestrian Alert use case leverages the LiDAR technology with sensors mounted on all four corners of the intersection. These sensors are continuously capturing objects in the crosswalks. When the local logic on the roadside compute classifies the objects as humans/pedestrians, the RSU is instructed to broadcast a Personal (Pedestrian) Safety Message (PSM).

There Kinetic Edge and Fog Processing Module made it user-friendly for the end user to perform a variety of analytics on the information coming in from the CV environment. One of the analytics Cisco performed for the testing team was Deduplication. In a CV environment where there will be a large saturation of OBUs, duplicate BSMs could be received by one or more RSUs. OBUs send BSMs at 10 times per second, therefore duplicated messages would increase the amount of storage needs. Cisco was able to demonstrate the ability of not receiving duplicate messages and to discard them as well other functions such as stripping the messages down to just receive certain metrics. Along with Deduplication, Cisco also showed the ETL process for the messages being received.

Cisco was in the lab for several days displaying the functionality of their equipment. During the week of testing, they hosted participants from several Districts and reviewed all the capabilities of their system. They were scheduled to go “live” with on 10/1/19 with their SR 50 deployments.

Final Notes

o Cisco demonstrated SPaT, MAP, TIM, PSA as well as receiving and transmitting BSMs.o EVP and TSP will be demonstrated during Phase 2 of the project, TBD.o Was successful in integrating with all the signal controllers at the D5 Seminole County Lab.o Was able to receive CV messages on the D5 Commsignia and Cohda OBU.o Cisco demonstrated their GUI.o Cisco demonstrated the capabilities of their software to include performing deduplication and ETL process.o Cisco only used the RSUs they brought down, we did not test with the D5 RSUs.
