Project Overview

About This Project

Continental Transport's dispatch team managed 500+ commercial vehicles through driver phone calls. No GPS tracking, no fuel analytics, no driver behaviour monitoring. Fuel card data showed an 18% variance from expected consumption — suspected theft or misuse — but there was no way to investigate. Three major breakdowns per month from overdue maintenance were costing $85K per incident in breakdown recovery, client SLA penalties, and contract penalties.

We built TrackFleet in 16 weeks: OBD-II and GPS telemetry units deployed fleet-wide streaming data via MQTT to AWS IoT Core, a React operations dashboard with live map and geofencing, driver scorecard and behaviour analytics, predictive maintenance alerts, a React Native driver mobile app with digital DVIR, and fuel analytics — delivering 22% fuel savings and 35% accident reduction.

The Problem

Challenges We Solved

No Real-Time Vehicle Location

Dispatch managed 500 vehicles entirely by driver phone call. Dispatchers had no idea where vehicles were unless they called. Customer ETAs were guesses. Unauthorised route deviations were undetectable unless reported.

35% of Fleet Overdue on Maintenance

Without automated maintenance tracking, service intervals were managed in a spreadsheet updated manually — and often ignored during busy periods. Three major breakdowns per month cost $85K per incident in recovery, penalties, and lost contracts.

18% Fuel Variance — Suspected Misuse

Fuel card data showed 18% more fuel consumed than expected for the mileage driven. Without GPS data to correlate fuel card usage with vehicle location and idle time, the cause was unknown and unactionable.

Accident Rate Driving High Insurance Premiums

Driver behaviours — harsh braking, speeding, aggressive acceleration — were invisible without telematics. The accident rate was generating insurance premiums 40% above industry benchmark, costing $420K per year in excess premium.

45-Minute Paper Vehicle Inspection Reports

Drivers completed pre-trip and post-trip inspection reports on paper — a 45-minute process per driver per day. Reports were filed and rarely reviewed. A defect identified in an inspection wouldn't necessarily be actioned before the next departure.

No Geofencing or Route Adherence Tracking

Vehicles departing approved routes, stopping at unauthorised locations, or working outside contracted hours were invisible to management. Client contracts included geofence compliance clauses that Continental couldn't verify.

Our Approach

How We Solved It

GPS/OBD-II Telemetry with AWS IoT Core

OBD-II and GPS telematics units installed fleet-wide stream position, speed, engine data, and diagnostic codes every 30 seconds via MQTT to AWS IoT Core. Operations dashboard shows all 500+ vehicles on a live map with real-time status, alert overlays, and geofence boundaries.

Predictive Maintenance from OBD-II Diagnostics

OBD-II diagnostic codes and engine hours analysed by a predictive maintenance model to flag vehicles approaching service milestones 2–3 weeks in advance. Maintenance team receives prioritised work order list daily. Breakdown frequency dropped from 3/month to 0.4/month within 90 days.

Fuel Analytics Correlating GPS and Card Data

GPS mileage, idle time, and fuel card transactions correlated to identify anomalies — stop-and-idle fuel waste, card swipes away from the vehicle's GPS position, and consumption outliers by vehicle and route. Fuel misuse cases identifiable within 24 hours of occurrence.

Driver Scorecard with Per-Trip Behaviour Metrics

Per-trip driver scorecards measuring harsh braking events, harsh acceleration, speeding duration, mobile phone usage (via OBD-II distraction detection), and idle time. Weekly driver reports shared with managers and drivers. Average driver safety score improved 41 points in 6 months.

React Native Driver App with Digital DVIR

Driver mobile app with daily DVIR (Driver Vehicle Inspection Report) — a structured checklist with photo evidence capture for defects. Completion takes 4 minutes vs 45 minutes on paper. Defects route instantly to maintenance team with photo evidence and vehicle ID.

Geofence Builder with Real-Time Alert System

Visual geofence builder allowing dispatch to define permitted areas and routes per vehicle or fleet group. Any deviation triggers an instant alert to dispatch with vehicle ID, driver name, and location. Client compliance reports generated automatically for SLA verification.

Results

The Outcomes

Month 4 — Fleet Live
First Predictive Maintenance Alerts

500+ vehicles live with real-time GPS. First predictive maintenance alerts issued — prevented 2 breakdowns in the first month. Fuel anomaly analysis identified 12 vehicles with above-average consumption; 4 cases of card misuse confirmed and actioned.

Month 8 — Full Impact
22% Fuel Reduction · Safety Score +41

22% fuel cost reduction ($960K annualised). Average driver safety score up 41 points. Accident frequency down 28%. Insurance broker notified of telematics deployment — preliminary premium reduction quoted at 18%.

Month 16 — Platform Mature
35% Accidents Down · Insurance -28%

35% accident reduction over 12 months of operation. Insurance premium reduced 28% at renewal — $420K annual saving. Maintenance costs down 31%. 4-minute DVIR replacing 45-minute paper process. Continental won 2 new enterprise transport contracts citing TrackFleet compliance reporting as the deciding factor.

35% Fewer Accidents. 22% Less Fuel. Built in 16 Weeks.
TrackFleet put Continental Transport's 500-vehicle fleet under real-time management for the first time.
★★★★★
"TrackFleet paid for itself in 4 months on fuel savings alone. But the safety improvements are what matter most — 35% fewer accidents means our drivers are going home safe, and our insurance premiums reflect that. The predictive maintenance has essentially eliminated unplanned breakdowns. We've gone from reactive to genuinely proactive fleet management."
