What Are The Blue And Green Lights On The Smartdrive Camera System

Nauto Forbid uses an inward-facing camera and algorithms to identify distracted driving behaviors while a vehicle is moving.

In 2016, commuter lark was a factor in six percentage of the 4,564 lives lost in fatal crashes that involved large trucks or buses. The same crash information, from the Federal Motor Carrier Rubber Administration, shows cell phone use was related to 16 percent of the fatalities.

Speeding is a higher fatal crash take chances, particularly for truck drivers themselves. Speed was a gene in 17 percent of large truck crashes where one or more fatalities were truck occupants.

Fleets can identify these and other symptoms of risky driving behaviors from result data reported by telematics systems connected to vehicle ECUs and sensors. Examples include speeding, rapid deceleration, lane departures and swerving.

This and other result data may be inadequate to identify the root causes of risky driver behaviors, yet. The latest advancements in vision-based safety systems can spot bad behaviors at their source and alert drivers the moment they surface.

Possibly more than importantly, the applied science can give instant feedback and coaching to direct positive modify.

Nudging versus nagging

Several companies have vision-based safe systems that place take chances by combining issue data with live video from inwards and outward-facing cameras. The systems utilize algorithms that notice patterns in complex data sets.

Exactly how these safety technologies should collaborate with drivers in a live environment is a matter of contend. Could giving drivers visual or audible alerts cause more problems than they forestall?

The SmartDrive vision-based condom platform has a network device that connects with cameras, electronic command units (ECUs), sensors, and various OEM and third-party avant-garde commuter assistance systems (ADAS) in vehicles.

A sensor bar for SmartDrive's SR4 platform has indicator lights that fleets tin can use to alert drivers to risky behaviors.

The software algorithms onboard the device instantly observe patterns of risky behaviors known every bit trigger events. The events trigger the capture of video and event data for review by SmartDrive's managed service.

The company has a line of SmartSense products that utilise machine vision to detect complex behaviors in existent time. Ane production monitors middle movements and caput positions of drivers to detect inattention, lark and drowsy driving behaviors.

For these and other types of risky behaviors, SmartDrive has customers who opt to give drivers real-time feedback using greenish, yellow and scarlet-light notifications on the camera.

"Information technology'southward important to strike a balance betwixt the value of alerting drivers immediately and what can be addressed afterward — and then as not to overwhelm them," says Jason Palmer, chief operating officer of SmartDrive.

Samsara offers a nuance photographic camera every bit part of a armada management and data platform that combines existent-time GPS tracking, electronic logs, wireless sensors, video, and mobile applications.

The platform is used by more than five,000 fleets. It coaches drivers in the moment using voice alerts that capture their attention. The alerts include "harsh event detected" for aggressive braking and aggressive turns, and a voice warning when drivers exceed a fleet's top speed threshold.

Vocalism alerts for these behaviors volition shortly be augmented with tones, says Saleh ElHattab, product manager.

The system's camera vision engineering science can detect distracted driving and tailgating events by analyzing a drivers' gaze, following distance and nearby objects. But Samsara does not requite drivers real-time alerts for these behaviors to maintain brownie. The system will have to detect distraction and tailgating behaviors with 100 percent accuracy before Samsara will add real-fourth dimension alerts, he says.

'You lot are distracted'

Nauto'due south dual-photographic camera computer vision arrangement, Nauto Coach, uses a device that mounts near the rear-view mirror that captures and transmits video and data of risky driving events to a web portal for review by fleet management.

Nauto Prevent is an optional production for Nauto Coach that uses the inward-facing camera and algorithms to identify distracted driving behaviors while a vehicle is moving.

The web portal shows risk profiles of drivers based on Nauto'south Visually Enhanced Risk Assessment (VERA) scoring method that focuses on attentive driving, speeding and smooth driving (accelerometer). Attentiveness is the near heavily weighted factor, with Nauto analysis showing distraction is a factor in 70 percentage of collisions.

Algorithms of Nauto Prevent monitor a driver's head, eyes and body to determine if eyes are on the road, says Sanket Akerkar, senior vice president of Nauto'south fleet and insurance lines of business.

Drivers get progressive in-cabin alerts if they are distracted while a vehicle is moving. A commuter is not alerted for looking at a cell phone at a cease calorie-free, for instance. The severity of risk is based on the length of time a driver is not looking at the road and the speed of the vehicle.

Drivers hear a beep at the beginning sign of distraction. If they continue the behavior the device will say "distracted." After 4 seconds the tone becomes more severe to command their attending.

Maintaining trust

Companies that develop vision-based safety systems say that alerting drivers to risks in their environment is counterproductive unless drivers trust the accurateness of the alerts.

Bendix Wingman Fusion combines radar and photographic camera inputs to warn drivers of collision risks.

Nauto has tuned its algorithms to limit "false positives" for distracted driving. These events are as close to zero equally possible, Akerkar says, to build trust. Limiting false positives has tradeoffs, since the system may featherbed distracted behaviors that are not as obvious in order to maintain that trust, he explains.

A vision-based organisation needs to comprise multiple sensors to have an constructive algorithm and preclude false positives, says SmartDrive'southward Jason Palmer.

"When testing SmartSense against standalone solutions, we found that if a commuter is going around a bend, he or she is looking at the curve and non straight ahead," he says. "A dual camera configuration is necessary to show that the lines in the road are paired to the driver'southward eyes and eliminate the false positive that another organisation is measuring."

The Bendix Wingman Fusion system adds a camera to work with the radar of Wingman Advanced for collision mitigation. The combo delivers more than information to the system, which enables an earlier read on situations to have fewer false alerts and false interventions.

For instance, the camera helps the radar determine if the object ahead is a stalled vehicle in the lane of travel, says Fred Andersky, manager of marketing and customer solutions, Bendix Commercial Vehicle Systems.

The Bendix safety systems can exist adjusted to fit a fleet or owner-operator's need for specific alarm strategies. Some want a more than conservative approach with following distance alerts at 3 seconds, 2 seconds and i 2nd at highway speeds. Others may want a more than aggressive approach, he says.

Bendix offers a Web portal chosen SafetyDirect that provides fleet operators with videos of severe events along with feedback on fleet and driver performance. The organization wirelessly transmits real-time video data and event-based data for assay past fleet safety personnel.

Samsara automatically records harsh events for review by driver managers through a spider web-based portal. The video events are made bachelor in near existent time in the Safety Inbox feature, tagged with labels for the risky beliefs detected.

Fleets can change the automatic labels on the videos if necessary. When tags are inverse it provides instant feedback to Samsara, which farther improves the accuracy of the camera vision technology to discover gamble, ElHattab says.

Cocky-coaching tools

Likewise giving drivers real-fourth dimension feedback, fleets are using technologies that permit drivers motorcoach themselves. The self-coaching strategy is most applicative for prophylactic infractions that fleets believe drivers can correct simply past being aware of the problem.

Fleets that use the DriveCam plan tin accept certain consequence videos sent to drivers automatically to review in a responsive spider web application.

Lytx offers a managed service, DriveCam, that includes review of event video by Lytx analysts who find for driver behaviors such as distraction.

Drivers are also alerted to risky behaviors in the cab. The ActiveVision platform from Lytx gives existent-fourth dimension feedback to drivers while capturing video of risky events for review through the DriveCam programme.

ActiveVision monitors lane markings and surrounding vehicles to place certain patterns of risk and issues real-fourth dimension audible alerts for distracted and drawn driving. One of the aural alerts is a rumble strip sound for patterns indicative of distracted or drawn driving such every bit unintentional lane departures.

For brusk following distances ActiveVision gives a sequence of beeping noises, says Kristin Costas, director of product management for Lytx.

Fleets that utilise the DriveCam plan can decide to have certain event videos to be sent automatically to drivers to review through a responsive web awarding. Drivers login and review curated issue records and a 90-day score.

The types of behaviors fleets typically assign for cocky-coaching are more frequent and lower risk such every bit non using a seatbelt or close post-obit distances, she says. As a standard, DriveCam gives drivers four days to motorcoach themselves before an consequence is flagged equally overdue.

SmartDrive has an app that drivers can use to think functioning scores, video and any condom observations. The app gives drivers the power to self-evaluate, manage bad habits and work to improve skills with greater visibility into their progress.

The Driveri Mobile Motorcoach app from Netradyne gives drivers videos of recorded events for grooming.

"When management and drivers are equally engaged in identifying strengths and weaknesses, while acknowledging improvement, self-coaching begins to operate as a supporting asset to the training programs the company has in place," Palmer says.

Bendix recently developed a telephone application that allows for information from its SafetyDirect portal to be downloaded directly to a phone to become data chop-chop to fleet managers and to drivers.

Through the same mobile application that Samsara uses for its ELD awarding, drivers tin can view a safety scorecard that updates weekly to see where they rank against their peers in a leaderboard. Drivers can besides login to a split up Driver Safety portal to obtain more granular feedback and see the locations where they had harsh events.

Samsara has called not to include video records in the Driver Condom portal. This is done to protect the privacy of drivers and fleets, he says, past preventing the unauthorized use or distribution of video event records, ElHattab says.

Automated preparation

Coaching and training drivers based on video and event records can exist difficult, particularly if drivers are on the road for days and even weeks at a time.

New developments can lighten the brunt of fleet managers past giving drivers immediate notifications and reminders before the events are recorded and sent to their fleets for review.

Netradyne has adult a suite of in-cab alerts for its Driveri ("driver center") vision system for following distance, speeding, rolling stops and yawning as an early sign of fatigue. The organisation tin also alert for distraction by monitoring drivers' eye and head movements, says Adam Kahn, vice president of fleet business concern.

Netradyne is currently working with early adopter customers to have the real fourth dimension alerts activated on their units before finalizing the products for broader commercial release.

"We spent a lot of time ensuring the precision and accuracy is super high," Kahn says.

Its armada customers can use the Driveri Mobile Motorcoach app, which gives drivers their electric current "GreenZone" rubber score at the end of each trip. With the app drivers tin can review videos of recorded events for training, which are selected and curated by fleet managers.

The app likewise shows drivers what behaviors they can change, such as speeding, to increase their scores, Kahn says.

The Mentor app from eDriving gives drivers a estrus map that shows where their risky events occurred.

eDriving has a smartphone and telematics software-as-a-service platform, Mentor, that fleets tin use as office of a closed-loop chance management programme that includes online driver preparation courses.

The Mentor app runs on smartphones or tablets and tracks driver behaviors for acceleration, braking, speeding and distraction by detecting if drivers choice up their phones while driving.

The app gives an audible alert to drivers when they exceed a maximum speed setting.

When non in motion, drivers tin can use the app to view their scores. A first-level summary shows the number of run a risk events for each category. Clicking on summary information opens a rut map that shows where the events occurred.

Commuter managers cannot view the upshot map. This approach ensures drivers have privacy of their ain information, says Ed Dubens, chief executive of eDriving. Managers tin view the number of gamble events for each driver and their Mentor scores for coaching the well-nigh at risk drivers in the fleet.

Mentor has an integration with ELD and telematics platform Geotab and with Nauto to use additional data captured past these systems for scoring driver risk, he says.

Mentor'southward online training modules are delivered through the app. Typically, fleets assign all drivers in the fleet quarterly preparation that takes 20 to xxx minutes to complete. High-gamble drivers can exist automatically assigned weekly courses based on specific behaviors that take three to five minutes to complete, he says.

Profitable with autonomy

Autonomous trucks are on the horizon every bit vehicle condom systems continue to advance. Motorcar vision engineering science will continue to play an agile role in monitoring the environs to ensure drivers are set up to take control at a moment'due south notice, says SmartDrive's Jason Palmer.

"The backup driver for an autonomous vehicle must be as attentive as if they were behind the wheel of a not-autonomous vehicle," he says. Armada managers will have information to understand how and why the driver got into a state of affairs where a vehicle's braking and steering systems had to accept control to prevent collisions, for case.

"Our job is to deliver the applied science that guarantees drivers are using newer technologies in a safer manner equally we progress up the ladder to full autonomy," he says.
