Trajectory optimisation for inland water vessels based on a next generation PNT-unit

Routing and manoeuver planning are accepted tasks of deep sea vessel navigation to increase the safety on sea and to improve the time- and resource efficient transport of goods and passengers. Trajectory optimization of inland water vessels is a similar navigational task intended to ensure a safe passing of bridges and an efficient locking of vessels. A resilient provision of position, navigation, and timing (PNT) characterising vessels´ position and movement in real time is an essential basis for a reliable description of traffic situation. At last the quality and completeness of traffic situation parameter and the applied mathematical optimisation procedure determine the effectiveness and reliability of trajectory optimization. The paper presents the general architecture of a driver assistance system and discusses an optimisation approach based on first numerical results.
