Abstract—this paper develops a real-time traffic signal timing model which is to be integrated into a single intersection for urban road, thereby solving the problem of traffic congestion. We analyze the current situation of the traffic flow with release matrix firstly, and then put forward the basic models to minimize total delay time of vehicles at the intersection. The optimal real-time sign...

In this study, we estimated dangerous traffic situations by installing a driving support system and using a microscopic traffic simulation which was modified by adding the function of perception-response process. In this approach, a dangerous situation is assessed by detecting conflict through simulation. For this assessment, a safety indicator named TIDSS (Time Integral of Difference of Space ...

This paper shows a configuration scheme for networks with WFQ schedulers that maximizes the amount of best effort traffic carried. We focus on those cases where traffic flows would congest critical links and lower network performance. The proposal is based on a Linear Programming formulation. The solution provides the weights that will allow us to control the best effort flows and reach the opt...

The limited efficiency of current air traffic systems will require a next-generation of Smart Air Traffic System (SATS) that relies on current technological advances. This challenge means a transition toward a new navigation and air-traffic procedures paradigm, where pilots and air traffic controllers perform and coordinate their activities according to new roles and technological supports. The...

In many Asian metropolitan areas and large cities, transportation issues are major concerns among ordinary citizens and policy-makers alike. Road congestion is the most common issue, arising when traffic volumes exceed the free-flow design capacity of the facilities that channel traffic flows. Recognizing that excessive congestion imposes a cost on individuals, society, and the city as a whole,...

We present a fuzzy decision support system that can be used in traffic control centers to provide a limited list of appropriate combinations of traffic control measures for a given traffic situation. The system is part of a larger traffic decision support system (TDSS) that can assist the operators of traffic control centers when they have to reduce non-recurrent congestion using a network-wide...

As we know the population of metropolitan is growing every day. With increasing country population, amount of vehicles is also rising, and this direct enchases traffic of cities which should be manages as early as possible without any loss people. Traffic causes accidents which directly affect an individual life. In the last 10 years the situation has get worse due to quick growth of automobile...
