  • Estimate travel time based on the simulation of traffic flows

    To solve the traffic problems , namely the coordination of the movement of transport modes have been developed micro-and macro-modeling programs that predict traffic situations , to choose the most appropriate solutions for specific problems by using real data and statistics. The emergence of intelligent transportation systems, traffic simulation pushed to the fact that it has become one of the most used methods for studying the traffic flow, allowing to plan and predict the situation on the roads. The possibilities offered by the modeling of traffic flows , helping to simulate the situation on the roads, and it becomes a unique tool for understanding the complexity of transport systems. For precise work of model needs an indicator such as the time of the trip. Travel time - the time it takes to travel from one point to another , consisting of travel time and the stop time of the vehicle.

  • The introduction of a new method of traffic light control on the road network of modern cities

    Traffic light control for urban road network has for several decades been one of the most important areas of study and application in order to ensure maximum efficiency . During this time he developed a variety of techniques and tools , a lot of research . But with the ever increasing number of cars and , as a consequence , poor road conditions and increases in the amount of traffic congestion , require more and more new and advanced techniques that would have allowed not only to solve the existing problems , but also to predict the possible developments in the future. Traffic congestion on the road network of the city continues to be a growing problem of modern cities . Possible reduction of traffic congestion can be achieved either by the constant increase in the volume of road surface, or by reducing the demand for personal vehicles . If we assume that the improvement will be achieved by increasing the number of roads , it is possible to face the fact that it is not always feasible , given the current road infrastructure . Accordingly , it follows that it is necessary to focus on the use of traffic management to reduce congestion and subsequent increase in urban transport mobility .
