Solving traffic accidents and problems to keep smooth travel and safe travel has become a top priority in road construction. In this paper, how to optimize the traffic at the intersection of the urban road was discussed with the aim of reducing traffic accidents and problems to keep peoples’ smooth travel and safe travel.展开更多

Functionally, it has emerged as the organizational necessity of both the universal complex structure and the importance of its overall activity. It was created on the basis of Article 57 of the United Nations Charter, stipulating that the specialized UN agencies are autonomous international organizations. They enjoy their autonomy on the basis of the contract they were established by, being engaged in activities within the United Nations system. On the territories the organization member states comprise, they enjoy privileges and immunities, having the international legal capacity to carry out their activities in accordance to the Statute. The 1944 Multilateral Convention was to establish both protection and efficient development of international civil aviation. In accordance to that rights and obligations of member states were established. It is of a special importance to emphasize obligation of parties to take their parts in both co-operation and programs aimed at improvement of international transport, navigational equipment, and installations. In the globalized world of today, air traffic is an irreplaceable part of the system of communication. It enables fast and timely business contacts between the people from various continents, as well as transport of goods.展开更多

In particular, we focus on wireless network- ing between cars. One of many technologies that make road traffic safer and more efficient is the Virtual Traffic Light （VTL） system, which is able to coordinate the traffic flow at intersections without the need for physical lights. VTL takes a leading vehicle at an inter- section and uses it to control the traffic lights. We developed algorithms for leader election and traffic light computation in realistic ve- hicular networking scenarios. Our key contribution is the extension of this algorithm to support arbitrary intersection layouts. We in- vestigated the proposal in synthetic and realistic scenarios. The results show that, overall, VTLs use network resources efficiently and positively influences driving experience. It performs better than stationary traffic lights for a low to medium network load. We also identify potential optimizations to deal with high network load and to improve fairness.展开更多
