Bosch also is working on a similar project with
Ford installed 'infrastructure nodes' outfitted with sensor arrays at intersections
in Michigan and Florida that provide a birds-eye view of the intersection
to augment AVs' ground-level observation of an intersection.
Michigan DOT along a 7-mile (11.3-km) stretch of
Detroit's M1 highway, also known as the Woodward
Corridor. " We're installing camera-based smart infrastructure
at about 57 intersections, " Sgambati noted.
In a similar vein, Ford- and VW-backed AV company
Argo AI have partnered with Rapid Flow Technologies to
use traffic cameras at intersections to collect data, including
the number of vehicles, pedestrians and other road users
approaching a traffic light. Rapid Flow Technologies'
Surtrac AI platform generates predictive models that allow
Argo vehicles to not only react to other road users in an
intersection but also predict their behavior.
AV company Motional, a joint venture between
Three intersections
in Marysville, Ohio,
are fitted with Bosch
cameras and a " Connect ITS "
system made by traffic-infrastructure
supplier MH Corbin. The information captured
by camera is sent to vehicles using DSRC.
using that to determine - just like an AV's sensors
and software - whether a pedestrian or a bicyclist is
in the roadway. "
For example, Bosch, the Ohio DOT and other
partners have developed a Smart Mobility Corridor along
US-33 near Columbus. The 35-mile (56-km) stretch of
smart roadway runs through cities such as Marysville
and Dublin that also are partnering with Bosch through
Drive Ohio, the smart-mobility division of the Ohio DOT.
" It's a test bed to use video as a sensor to augment
automated and connected vehicles and make automated
driving safer and more seamless, " Sgambati said.
" It's really foundational work. "
In Marysville, three intersections have Bosch
cameras as well as traffic-infrastructure supplier MH
Corbin's CONNECT:ITS system that takes information
from cameras and sends it to vehicles using Dedicated
Short Range Communication (DSRC) technology.
" Vehicles that have DSRC capability can get information
before they approach an intersection, " Sgambati
explained. " That's an early example of that technology. "
Hyundai and Aptiv, recently initiated a pilot with Derq,
which supplies real-time images from traffic cameras and
data from roadway sensors to government agencies and
mobility companies. As part of the pilot, cameras positioned
above busy intersections and connected to Derq's
roadside computers transmit data to Motional's vehicles.
Derq's data provides Motional AVs with a view of
an intersection that their onboard cameras and sensors
may not normally see and can help an AV detect pedestrians
crossing a street behind parked cars or cyclists
weaving through traffic at a red light, for example.
Derq's technology also can predict movements of other
road users to alert Motional's AVs of difficult traffic
situation before a vehicle enters the intersection.
Smart traffic lights
AV developers also are working with cities to install
new transportation infrastructure, mainly at intersections.
For example, Ford is working with Argo to help
equip cities with technology for its impending deployment
in Miami, Florida and Austin, Texas.
To help prepare for Argo's deployment in MiamiDade
County, Ford installed " infrastructure nodes "
the automaker designed in-house and installed at two
intersections in the Detroit suburb of Saline, Michigan.
Equipped with cameras, radar and lidar sensors and
perched above the intersection, the nodes provide a
birds-eye view of the intersection to augment an Argo
AV's ground-level observation of an intersection.
Ford has since installed the same type of smart
infrastructure nodes in Miami Beach to communicate
