Modernizing In-Cab Operations for Safety, Scale, and Reliability Across a National Logistics Network

The Challenge

A leading logistics operator running one of the world’s largest transportation networks relied on an in-cab operational system used daily by ~30,000 drivers across a fleet of ~135,000 vehicles.

The system originated as a response to federal electronic logging device (ELD) mandates designed to improve driver safety through enforced limits and better visibility into driving behavior. It met those requirements consistently and, over time, became deeply embedded in daily fleet operations. As the system took on mission-critical responsibility inside the cab, it did so without the architecture, usability, or extensibility required of a safety-critical system. The design concentrated on logging mechanics and left proactive safety intervention underpowered.

Key challenges included:

A Compliance-First System Asked to Carry Operational Weight

The original system was built quickly to meet federal electronic logging device (ELD) mandates. Its purpose was narrow: capture hours of service, mileage, and driver logs. Over time, additional features were bolted on to support routing, yard navigation, and operational coordination, without a coherent system redesign. The result was a fragile foundation carrying far more responsibility than it was designed to handle.

Change Introduced Risk Instead of Progress

The system had become so tightly coupled that even small updates triggered downstream breakage. Teams were effectively locked out of making improvements—whether to address new regulatory requirements, enhance safety workflows, or improve the driver experience—because change itself had become a risk.

Operational Reality Was Missing From System Design

The system was designed without direct input from the people using it most: drivers operating large vehicles under real-world conditions. Interface decisions ignored factors like screen size, glance time, and interaction constraints while driving. Information density increased, but clarity did not.

Operations Required Safer, Earlier Signal

Modern tractors and trailers generate continuous mechanical and safety signals including tire pressure, wheel bearing temperature, speed, and other telemetry. The legacy system recorded required logs reliably enough to satisfy regulation. But fleet operations needed the next layer: signal interpretation that surfaced risk early enough to change behavior, protect drivers, and prevent high-cost incidents.

The Solution

Sparq began the engagement in the cab. The team went on-site, conducted ride-alongs with feeder operations, and worked directly with trainer drivers to observe how the system behaved under real driving conditions. Those insights shaped the redesign from day one: workflow sequencing, information density, interaction design, and the operational moments where the system needed to surface signal and guidance.

Key elements of the solution included:

A Central Hub for Vehicle Intelligence

The new system functions as a processing and decision layer for vehicle sensor data, aggregating inputs from tractors and trailers and turning them into operationally relevant signals. Safety-critical conditions (such as overheating wheel bearings or pressure anomalies) can now be detected and surfaced early, enabling timely intervention rather than post-incident response.

Safety Embedded Into Execution

The system was designed to support proactive, in-workflow safety decisions. Alerts, guidance, and required actions are delivered directly to drivers in context when conditions change, not after damage occurs.

Progressive Delivery Without Operational Disruption

Given the scale and regulatory sensitivity of the environment, Sparq delivered the solution incrementally. New capabilities were introduced in stages, allowing portions of the fleet and adjacent roles (maintenance, fueling, testing) to begin using the system while legacy components remained active. This ensured continuity while moving steadily toward full replacement.

A Modern, Extensible Architecture

Sparq redesigned the system architecture to decouple core capabilities, allowing new functionality to be added without destabilizing existing workflows. This created a foundation capable of evolving alongside regulatory change, operational needs, and future intelligence use cases.

Product Leadership Inside a Multi-Year Transformation

Over a multi-year engagement, Sparq provided sustained product leadership, establishing roadmaps, sequencing releases, and aligning stakeholders around a shared long-term vision. This prevented the initiative from stalling under its own complexity and ensured progress continued even as scope expanded.

The Results

The outcome was a modern, regulated driver operations system built to perform under real-world pressure and evolve safely over time.

Key results included:

Improved Safety Through Earlier Intervention

By processing sensor data into actionable signals, the system enables proactive identification of mechanical risk conditions, reducing the likelihood of catastrophic failures that endanger drivers, cargo, and equipment.

A Platform That Supports Change Instead of Resisting It

What was once a brittle compliance tool is now an extensible operational foundation capable of absorbing regulatory updates, workflow improvements, and future intelligence capabilities without destabilizing fleet operations.

Reduced Operational Friction for Drivers

Driver workflows were simplified and clarified through human-centered design, reducing cognitive load and minimizing unnecessary interaction, particularly important in high-risk driving environments.

Scalable Adoption Across a Large Fleet

The system supports tens of thousands of drivers and vehicles, with production usage expanding through phased rollouts aligned to regulatory certification and operational readiness.

A Foundation for Future Intelligence

While the system delivers immediate operational value today, it also establishes the data, architecture, and governance required to support more advanced fleet intelligence over time, without requiring another foundational rebuild.

This engagement demonstrates Sparq’s approach to operational re-engineering in its purest form: get inside the system that actually carries risk, pressure, and accountability, and redesign how it behaves under load.

Not as a demo or a pilot, but as a production system drivers trust with their safety every day.
