1.Client Background

A cold chain logistics company transporting perishable goods (dairy, vaccines, meat products) across 12 states operated a fleet of 280 refrigerated trucks. However, they lacked a unified system to monitor vehicle health, cargo conditions, route efficiency, and delivery schedules. Delays, fuel misuse, and spoilage due to poor temperature control were impacting both profitability and client satisfaction.

2. The Challenge

The core issue was visibility. The company had no real-time insights into vehicle routes, driver behavior, refrigeration status, or fuel consumption. Manual trip sheets led to billing discrepancies. Moreover, clients had no way of verifying whether their goods were transported under proper cold chain compliance. They needed a centralized, real-time platform for fleet tracking, cargo monitoring, route optimization, and reporting.

3. Our Approach

Warke Technologies conducted fleet ride-alongs, interviewed dispatchers and drivers, and audited cold storage data logs. We proposed a hardware-software integrated platform with IoT sensors on vehicles, GPS tracking, and AI-assisted route prediction. The platform would include mobile apps for drivers and web dashboards for fleet managers and clients.

We focused on reducing delivery delays, fuel wastage, and spoilage claims, while maintaining compliance with temperature-sensitive cargo standards.

4. Solution Delivered

We built a Smart Fleet & Cold Chain Monitoring System tailored to their transport operations:

• Vehicle Tracking & Route Optimization:
• Real-time GPS tracking with route playback
• Smart routing engine factoring traffic, fuel stops, delivery windows
• Geofencing alerts and deviation notifications
• Temperature Monitoring & Alerts:
• IoT temperature sensors inside truck containers
• Threshold breach alerts via SMS/email to fleet supervisors
• Continuous logs auto-synced to cloud for compliance
• Driver App:
• Trip start/end logging, route navigation
• Fuel input logging, inspection checklist submission
• Emergency support + chat with dispatcher
• Fleet Manager Dashboard:
• Live vehicle map with cargo condition overlays
• Driver scorecard (speed, idling, fuel efficiency)
• Trip-level reports, SLA performance, maintenance logs
• Client Portal (Optional):
• Delivery tracking with cold chain compliance proof
• Downloadable temperature log per delivery
• Alert subscription for sensitive cargo shipments

5. Technologies Used

• Frontend: React
