There were ready-made solutions for face recognition on the market, but there was no application for optical recognition with the functions that the client needed. Besides, it was important to take into account the specific features of the construction site. The system had to know, distinguish all models of specific vehicles such as excavators, concrete mixers or loaders and identify all their possible shapes and sizes.
This Progressive Web App recorded and processed data on incoming cars (model of this vehicle, registration number, etc), saving the time they stayed at the site. The application works in two modes: automatic and semi-automatic. If the system identified a particular car and found it in the list, then it could proceed to the construction site. If the vehicle was allowed to enter but the maximum number of cars was already on the site, then the system let a new one to pass only when the previous car had left. If the vehicle was not on the list, then the semi-automatic mode worked: the operator who received the notification could skip or reject the transport.
