How Does Worker Presence Detection Improve Safety?

Workers are the most vulnerable part of any work zone. With more than 850 fatalities and 41,000 injuries recorded in work zones in 2024, taking proactive steps to improve safety is more critical than ever. Worker presence technology enhances safety by automatically:

Alerting motorists via Waze & other platforms before they reach workers
Lowering the speed limit on digital speed signs
Displaying warning messages before the work zone
Activating warning beacons on signage
Informing stakeholders of work zone activity

How Does the Connected Worker Solution Work?

It all starts with a worker slipping a Connected Worker Module into their vest pocket. Upon entering a geofenced work zone, preconfigured safety measures can be automatically triggered, such as Waze alerts to motorists, safety messaging, a lower speed limit, flashing beacons, and informing stakeholders via the CWZ data feeds.

These safety measures are active as long as the worker is on site, offering an extra layer of protection. No manual intervention is needed, freeing up time and preventing errors.

When the worker leaves, the equipment automatically reverts to its previous configuration.

Making Workers Digitally Visible

Alerts can be sent to drivers via Waze and other navigation systems to combat distracted driving.

Being alerted of worker presence in advance gives drivers time to be alert, slow down, and proceed with caution as they approach the area.

Warning Messages Before the Work Zone

Message signs can automatically display predetermined warning messages when workers are present, including the distance to the first work crew.

These attention-grabbing warnings can reach drivers who are not connected to navigation apps and reinforce caution for those who are.

Speed Limit Automatically Lowered

Worker Presence Technology automatically lowers the speed limit to its predetermined speed when a worker is detected, ensuring:

A real-time, hands-free transition to a safer speed limit
Greater driver compliance by encouraging motorists to slow down only where workers are present
Safer conditions for both workers and motorists

Speed Enforcement Evidence

Generate reliable records of worker presence by integrating the Connected Worker Module with an Automated Speed Enforcement solution.

This approach provides evidence to ensure citations are issued onlywhen workers are present, making it particularly valuable in regions where fines increase when workers are on site, or when worker presence is required for enforcement.

Real-time Work Zone Status for Stakeholders

When a worker who is wearing the Connected Worker Module enters the geofenced area, the work zone’s status becomes active.

This information can be published via the CWZ data feeds, where it can provide DOTs, TMCs, and other key stakeholders with reliable visibility into work zone activity.

Knowing the real-time status of work zones helps plan resources and enable smoother mobility.

Benefits of Connected Worker Safety Technology

Proactive Safety

Advance warnings & alerts

Waze alerts cut through distracted driving & warn drivers to exercise caution.
Warning messages on digital signs reach drivers who do not use apps.
Lower speed limits help motorists slow down before reaching workers.

Real-time Visibility

Accurate field information

Government agencies and other stakeholders can be informed via the Connected Work Zone (CWZ) data feeds, informing mobility decisions and responses.

Reliable Records

Actionable data

Access worker presence records to support accountability, planning, and automated speed enforcement solutions.

Leverage Existing Signage

Enhance already-deployed devices

Worker Presence technology complements existing equipment, adding a new layer of intelligence that automatically reacts when workers are exposed to traffic.

Automate Work Zone Management

No manual intervention needed

Once configured, the system automatically activates safety measures exactly where and when needed. No risk of forgetting to activate the signage.

Frequently Asked Questions

What is a Connected Worker Module?

The Connected Worker Module is a compact device that a worker slips into their vest pocket. It measures 4 5/8 X 3 1/8 inches and weighs 4.4 ounces (125g).

This small but mighty device is the next step in connected work zones, helping to improve worker safety, automating work zone equipment signage in geofenced work zones, communicating work zone status to government agencies, and more.

How does the Connected Worker module protect the privacy of the workers who wear it?

The Connected Worker module is designed to record your location only when you are inside a worksite that has been pre-marked with geotags. Even if you are wearing the module on your way home after your shift, your location will not be recorded or shared. Furthermore, the technology does not allow the module to be linked to the worker wearing it. Location data is therefore anonymous.

What if my work zone is not geofenced? Can I use the Connected Worker Module?

You need a geofenced work zone to use the Connected Worker Module. If your work zone is not geofenced, you can use Ver-Mac's Work Zone Live app to indicate your presence online.

This can trigger advance warnings to motorists via Waze and other navigation systems, adding a layer of safety.

The Work Zone Live app also allows you to select the type of work you are doing for tracking and reporting purposes.

Learn more about the Work Zone Live app.

Is the Connected Worker Module easy to use?

It is very easy to use. It’s as simple as charging it after each shift and slipping it into a safety vest pocket.

The rest happens automatically when the worker who is wearing the device steps into the geofenced work zone.

Ver-Mac’s connected ecosystem activates, making workers digitally visible on Waze, displaying predetermined signage, lowering speed limits, and connecting to the CWZ data feeds. No risk of forgetting to manually log in or out.

What if I have any questions or need support when using the Connected Worker Module?

We’re here to support you and answer any questions you may have.

To learn more about the Connected Worker Module, please contact our connected solutions experts at connected.solutions@ver-mac.com

If you already have the Connected Worker Module and have technical questions, please contact Ver-Mac’s Support Team.

Is a vest included with the Connected Worker Module?

No, the Worker Presence Module is supplied as a standalone product, and can be slipped into the pockets of any safety vest.

Which speed sign or message sign can I use with the Connected Worker Module?

It is recommended to use the following speed signs with the Connected Worker Module:

Speed Wizard
Work Zone Digital Speed Limit Sign
Any portable changeable message sign can be used with the Worker Presence Technology.
