The project aims to build a prototype of a new sensor, a three-eye sensor and additional supportive software based on machine learning and computer vision. The purpose of this technique is to facilitate infrastructure-based information that can be used for traffic analysis, support for connected transport systems including autonomous vehicles, services for vulnerable road users, traffic research and urban planning in general. A common denominator for these tasks is the ability to detect and track road users like cars, pedestrians and bicycles, which will be the focus of the project.
