01CHALLENGE
What the project had to solve.
During peak season, a grain elevator turns into a traffic jam. Trucks arrive in crowds, drivers do not know when they will be admitted, and they keep calling the dispatcher. The dispatcher is buried in calls and has no complete picture of who is where, how long each truck has been waiting, or what cargo it carries. The result is idle time at the entrance, frustration on both sides, and no data for planning throughput.
The “paper and phone” approach works in the low season and breaks at the peak, when the queue is most expensive. The customer came with a specific task: eliminate the calls and the crowd, let drivers see their own position and time, and give the dispatcher a live view of the queue while the trucks are still on the road.
02SOLUTION
What we built and why.
We designed a system with three roles and built a clear demo so the customer could try the interface and confirm the logic before full implementation.
• Driver app — a “you are within the 50 km zone” banner, a simple form (vehicle number + volume + “join the queue”), and a “you are in the queue” screen with a large position number, ticket, time until call-up, and bay number. A driver needs only two answers: “am I already in the queue?” and “when should I enter?”
• Dispatcher panel — top-level indicators (within 50 km / in queue / at a bay / loaded today), a live map with vehicles and the zone radius, and an automatic queue with details in every row: company, cargo, volume, driver, phone, vehicle, time, and distance. The whole flow is visible on one screen, without calls or a paper log.
• Public board — a “loading now” screen (vehicle + bay + timer) and the list of trucks next in line. Like a station timetable, it answers “who enters now?” for everyone at once.
The cycle: GPS detects a driver within 50 km → the driver confirms the vehicle number and volume → the truck automatically joins the queue with a ticket → the dispatcher sees everyone on the map → the truck is called to a specific bay → loading is recorded in reports.
