02 / Driver AI Assist

Daily driving.
Personal progress.

I designed and built a functional app for commercial drivers. It brings daily priorities, route conditions, trip review, and AI-assisted coaching into one personal experience—giving the driver a way to understand their performance and act on it.

01 / Perspective

Two applications.
Two responsibilities.

The manager application helps a coach understand fleet events, organize follow-up, and delegate work. This application serves the individual driver: what needs attention today, what happened on a trip, and what to work on next.

The design shifts the driver’s role from receiving coaching to participating in it, with personal feedback, space to explain an event, and a guided learning sequence.

02 / Customer research

Help drivers understand.
Know when people need to step in.

Customer interviews about existing self-coaching programs reveal both the need for independent learning and its limits. These excerpts inform the app’s learning experience and the questions that still need evaluation.

01 / Customer insight

Reach drivers beyond the office

“A lot of drivers we can't reach them. They're over the road or they live too far so we can't reach them. When we first started, it was just Steve and I. So Steve had to cover over a thousand drivers probably, and I had to cover at that time probably over 300 as well. So we couldn't reach them. So that's why we needed something so we could have the driver self coach themselves.”

Design response

Make review driver-led

The app gives drivers a guided sequence of event reviews, learning modules, and feedback they can work through independently.

02 / Customer insight

Explain why the behavior matters

“I think the one of the bigger challenges with self coaching is first having the driver truly understand the behavior because if you've been doing it for so long and you don't understand that it's wrong… you feel truly what you're doing is right? So it kind of, it's a good thing to have them watch the video. Absolutely. But to coach the event out, what we probably saw from that is just still an influx and repeated behavior, because they don't understand why we feel this is wrong, why this should be corrected. They don't understand the why behind it.”

Design response

Go beyond watching a video

Behavior explanations and scenario questions connect the event to a learning point. Incorrect answers receive an explanation before the driver continues.

03 / Customer insight

Recognize behavior-specific limits

“The one we've seen with our DOT regulated fleet that we've noticed self coaching hasn't gone, hasn't worked very well is handheld device. They need a little push on that one. They need some in person on handheld device because we just see that that one doesn't improve unless there's a formal conversation.”

Design consideration

Keep human coaching in the model

This feedback identifies a limit to independent learning. The driver experience sits alongside the manager application; self-coaching effectiveness needs to be evaluated by behavior.

04 / Customer insight

Respond when the behavior repeats

“I mean if somebody's going through the workflow and they just keep doing it, that's, you know, a face to face is going to have to happen. Right… there's something, you know, when you're sitting there in front of your manager having to explain, you know, this is, you know, I almost ran somebody over, you know, I'm falling a little too close. You know, I ran the fifth stop sign today. It hits a little bit differently because you got to explain it to somebody.”

Evaluation priority

Look beyond session completion

The app shows behavior trends and progress, but completion alone does not establish improvement. Evaluation needs to examine repeated behavior and when manager follow-up is needed.

UX artifacts / Supporting work

From event viewing to guided learning.

The earlier self-coaching flow required drivers to watch an event through to completion, with notes optional. Driver AI Assist adds behavior explanations, contextual conversation, and questions with feedback.

Historical workflow

Self-coaching in the driver app

The earlier app flow documents event review and completion, alongside proposed measures of engagement. It provides a concrete reference for the newer guided coaching experience.

A driver’s working day

The working-day map places safety activities alongside preparation, routing, driving, and post-trip work. It gives context to the daily brief and route assistance shown in this app.

03 / Daily workflow

Prepare, navigate,
then review.

The driver moves from a daily brief to route risks and a trip-level explanation of performance.

A / PRIORITIES

Start with a personal brief

Daily Brief with weekly score, behavior trends, next stop, weather alert, and coaching focus.

A weekly score and behavior trends sit alongside the next stop and route conditions. Coaching focus areas turn performance feedback into specific daily priorities.

B / ROUTE CONTEXT

See risks to the schedule

Route Assist showing stop windows, rain, a delivery at risk, and Reorder Route and Dismiss controls.

Route Assist combines stop windows, weather, traffic, and location-specific alerts. A delivery at risk exposes a route-reordering action directly in context.

C / TRIP CONTEXT

Understand the event

Trip Review explaining a hard-braking event with score contribution, location map, and Get AI Debrief control.

Trip Review explains the score through contributing behaviors. Expanding a hard-braking event reveals its location, a plain-language description, and an entry point to an AI debrief.

04 / Conversation

Give the driver
a voice in the review.

The AI debrief opens with the specific event and asks what caused the hard stop. The driver can add context or ask a question within the review.

Ask for context

The prompt names the event, trip location, and score, then asks about possible causes. That makes the conversation about the driver’s situation.

Keep the exchange relevant

In the recorded test, the driver enters a deliberately fictional explanation. The assistant challenges it and asks for the actual circumstances. This shows the intended conversational behavior in that exchange.

05 / Improvement

Connect feedback
to the next action.

Progress tracking and event-based coaching carry the experience beyond a single score.

A / PROGRESS

Make improvement visible

Progress screen with peer ranking, clean streak, weekly goal, trophies, and current goals.

Behavior breakdowns and trends are paired with peer standing, streaks, and goals. The driver can track progress over time and see the next target.

B / COACHING

Review a specific behavior

Coaching Event Review with a hard-braking explanation, session behavior pattern, and related learning module.

Coaching organizes focus areas into an event review sequence. Each review pairs a behavior explanation with the session pattern and a related learning module. The interface also offers an event-dispute option.

C / FEEDBACK

Explain the answer

Hard-braking quiz showing the selected incorrect answer, the correct option, an explanation, and Next Event.

A scenario question checks the driver’s understanding. After an incorrect choice, the app identifies the correct answer and explains the reasoning before offering the next event.

06 / Product design

Designing across both sides of coaching

A / Product model

A distinct driver workflow

The driver’s experience centers on daily work and personal progress. The manager’s experience centers on fleet oversight and follow-up.

B / Interaction model

Context before conversation

Scores lead to specific behaviors and events. AI conversations begin inside that context, with an opportunity for the driver to respond.

C / Learning model

Feedback with a next step

Performance trends, event reviews, and explained quiz feedback connect observation to a concrete action the driver can take.
