Transport NL builds its own GPT – real results, real savings

Imagine ChatGPT functioning as a digital assistant: checking forms, identifying missing details, and even composing emails.
The Transport department in Rotterdam is making this a reality with its first Custom GPT Agent, specifically developed to validate incoming transport requests. This AI-powered assistant ensures that all critical fields, such as client name, material, quantity, loading location, destination, and loading window, are filled out.
It also applies internal business rules; for example, it checks for loading meters on part loads or flags the need for additional trucks if the weight exceeds 25.5 MT.
But the benefits go beyond identifying issues. The agent suggests fixes, rewrites requests, and can even generate a ready-to-send Outlook email in the correct language, complete with a validation summary and all of this within seconds.
The team has tested and fine-tuned the agent using real requests, ensuring that it matches the Transport department’s tone, formatting, and workflows. This serves as a strong example of how AI can support operational teams, not by replacing people, but by accelerating repetitive tasks and improving consistency.
Best of all, you don’t need to be a developer to build something similar. Any department can create a GPT agent tailored to their unique needs, whether that involves validating documents, answering internal FAQs, or extracting data into Excel.
