Schematics and Components

SMART Corridor

1) network of intersections with advanced sensors and V2X communication tech

2) collects data and has real time communication capabilities

3) objective is to prevent collisions, prioritize transit and emergency vehicles, and support data driven planning decisions

LiDAR

What does it stand for: light detection and ranging

How does it work: emits a laser pulse onto a surface and measures how long it takes to bounce back. Timing data creates a 3D map of the surrounding environment

CCTV

what it stands for: closed-circuit television

What it does: gives us real time visual data and can validate LiDAR, especially in snow and rain

RSU

What it is: roadside unit

What it does: streamlines communication between the different components

Example of RSUs: smart traffic signal systems, pedestrian and cyclist warning systems, toll collection portals, and work zone and weather alert stations

Edge Computers

What is it: enable real-time data processing and analysis

Example(s): autonomous vehicles can use onboard computers to analyze camera and sensor data instantly for split-second driving decisions

OBUs

What does it stand for - Onboard Units

What does it do: allows vehicles to send and receive V2X data

Communication System

What does it do: shares data between components
