Blueprint overview/Introduction

Connected Vehicle Blueprint(CVB) is an Akraino approved blueprint and part of Akraino Edge Stack. The project is completely focused on Connected Vehicle Application run on Edge Computing.

Use Case

The use cases for the Connected Vehicle Blueprint are itemized below. For R4, we release the latest Microservice Platform Tars, which supports the multiple connected vehicle application deployment/management/orchestration/monitor.

UseCases	value proposition
Smarter Navigation	Real-time traffic information update, reduces the latency from minutes to seconds, figure out the most efficient way for drivers.
Safe Drive Improvement	Figure out the potential risks which can NOT be seen by the driver.
Reduce traffic violation	Let the driver understand the traffic rule in some specific area. For instance, change the line prior to a narrow street, avoiding the opposite way drive in the one-way road, avoiding car pool lane when a single driver and so on.
Cooperative vehicle and infrastructure system	Real time road objects status is obtained by roadside sensing system. Based on the sensing data, the vehicle obtains the traffic warning and driving assistance informationwhich threatens itself.

Test case: The roadside camera recognizes the vehicles and pedestrians on the road through the edge computing server, and then pushes the pedestrian warning to the host vehicle (blue vehicle) .

Overall application Architecture

The following picture depicts the application architecture of the Connect Vehicle Blueprint, which consists of the following key components:

Commodity Hardware, Arm/X86 Physical Server.
Virtualization Layer.
Tars Microservice Platform layer.
Connected Vehicle Applications layer.

Connected Vehicle Applications include roadside traffic situation monitoring, driving risk assessment, road event perception, high percision positioning, and so on.

Overall deployment Architecture

The following picture depicts the architecture of the Connect Vehicle Blueprint, which consists of the following key components:

Commodity Hardware, Arm/X86 Physical Server.
IaaS Software, like Openstack, IaaS and so on
Tars Microservice Platform
Connected Vehicle Applications

The combination of Commodity Hardware and IaaS Software provides flexible deployments, like Bare Metal, Virtual Machine as well as Container.

Tars is a microservice framework that can manage/monitor/deploy the connected vehicle applications in the edge and data center. Tars can be flexibly deployed in Bare Metal, Virtual Machine as well as Container.

Connected Vehicle Applications are some different applications that fulfill Accurate Location, Smarter Navigation, Safe Drive Improvement, Reduce traffic violations, and cooperative vehicle infrastructure system.

Main Progresses for Release 4

Release 4 is the 4th release for Connected Vehicle Blueprint.

Build Of Materials (BOM) / Hardware requirements

Connected Vehicle Blueprint can be flexibly deployed in Bare Metal, Virtual Machine as well as the container.

For R4, we deploy it in Intel Pod1 Akraino LAB for Release. The detailed hardware is itemized below:

Hostname	Core	RAM	HDD	NIC	Role
Node-0	8	40GB	3TB	10GB	Jenkins Master
Node-1	8	96GB	3TB	10GB	Tars Framework 2.4.13
Node-2	8	96GB	3TB	10GB	Tars Node (CVB + Type4 Application + Virtual Classroom Teacher Client + Virtual Classroom Student Client)

Tars is an edge compute microservice platform with low latency, high quality.
