Micro Aerial Vehicles (MAVs) with hovering capabilities may support rescue forces. To enlarge the area of operation, a quadrotor with tiltable rotors is developed. In contrast to common quadrotors this new type of MAV is able to change its velocity independently of its attitude. To control these vehicles a control method from the field of nonlinear control is required. The control method described in this paper is separated into two parts: The first part connects the input signals from the vehicle to the required forces and torque applied to the vehicle while the second part is a backstepping controller generating desired forces and torque. To connect the input signals of the vehicle and the required forces and torque a method called adaptive dynamic control allocation is used. In this paper the proposed control method and its application to the quadrotor with tiltable rotors is explained in detail. The results demonstrate the performance of the controller. © 2017, Institute of Navigation. All rights reserved.

Experts emphasize on the need to maintain long-standing core competencies such as safety and operations. They state that it is essential to embrace required changes in the profession to better respond to the mobility needs of complex urban areas and to the rapidly evolving vehicle technologies that will impact surface transportation infrastructure. Transportation professionals are involved in all three aspects of safety, engineering, education, and enforcement. Professionals are making a difference in the movement toward zero deaths, whether it is through a downtown complete streets project or a road diet that results in a speed reduction, reduced pavement areas, improved pedestrian and bicycle facilities, or safe routes to school programs.

The construction of new highway and public transportation facilities has come under increased scrutiny in recent years. Costs, environmental concerns, and long construction periods have caused many communities to look for better ways of dealing with their transportation and mobility needs. Operational improvements and highway demand management strategies have been increasingly viewed as a way of addressing congestion and mobility problems. Major water crossings built included the George Washington Bridge in New York City, the Delaware River Bridge in Philadelphia, the Golden Gate and Bay Bridges in San Francisco, CA, and the Holland and Lincoln tunnels in New York City. Construction of roads took place as motorization steadily increased. Federal-state arrangements for classifying and financing intercity (and urban) roads were established.

Keith Golden discusses how Georgia, US, is dealing with its traffic congestion and other transportation challenges through various programs. The Georgia Legislature has passed House Bill 277 - Transportation Investment Act (TIA) of 2010 - to address the state's mounting transportation needs, such as declining infrastructure and increasing demands for new capacity. TIA 2010 provides the citizens of Georgia with the opportunity to determine the future of transportation in their communities. In fall 2011, commuters on I-85 began to benefit from Georgia's first high-occupancy vehicle (HOV) to high occupancy toll (HOT) lane conversion. The express lanes help manage traffic flow, offer motorists another commuting option, and provide more reliable trip times. A DDI is a relatively low-cost congestion and safety solution that enables meaningful improvements at clogged interchanges without expending huge sums of money and time.
