The principal objective of SIGNATURE is to prototype a GNSS based solution for flexible road user charging which provides a high integrity, or trustworthy, solution in a cost-effective and scalable manner. It will demonstrate that a robust solution can be based upon low-cost GNSS components provided the end-to-end service is intelligently designed.

The overarching scientific and technical objective of the project is to prototype the necessary algorithms, products, services and processes that will provide the required levels of confidence in adopting a GNSS solution for Electronic Fee Collection. Having confidence in GNSS to deliver reliable and continuous location information is a fundamental requirement in ensuring accurate, fair and flexible road user charging.
