This work describes a new technology for safer berthing at container terminals—laser ranging and laser docking, integrated with metocean data. What may seem a simple process, and perhaps at times is, nonetheless is potentially hazardous to the environment and to personnel. This timing of the development of this system is all the more serendipitous as the pressures of the port to take in larger ships continues, particularly container vessels. Adaptation of the port was made possible by a complex set of technologies, ranging from simple dredging to the sophisticated presentation of data to the pilots and to the maritime authorities.

A mathematical model for the dynamics of river vessels was derived. A standard 3D model / geometry of the river vessel has been developed and its resistance coefficient determined according to the incidence angle of the liquid.

Experimental results obtained during live GNSS jamming tests performed in a road environment. Different jamming detection strategies are considered with specific focus on signal agnostic approaches where no stringent model assumptions are made for the detector design. A measurement station made of a commercial GPS high-sensitivity receiver and an SDR front-end was deployed and used to collect measurements in the presence of jamming. The tests were performed using three different jammers and considering the effects introduced by a vehicle moving at different speeds. The advantages and shortcomings of the different detection approaches are analyzed, and the most effective detection strategies are selected.

The paper shows that road geometry has a great impact on overall fuel consumption and emissions. Some roads connect traffic origins and destinations directly, while some take winding, indirect routes. Indirect connections result in longer distances driven and increased fuel consumption. A similar effect is observed on congested roads with stop and go traffic and on mountain roads with many changes in elevation. In this light, we propose a methodology for analysis of road networks based on energy consumed by the vehicles and the energy needed to build more efficient connections. This framework takes into consideration traffic volume, shares of vehicle classes, road geometry and energy needed for road operation and construction. Its application was illustrated through two case studies, one with macroscopic traffic data and one with microscopic traffic simulation that can also be applied for urban road network optimization.
