Original scientific paper Urban road intersections are bottle-necks of urban road networks, and the traffic organization optimization of intersections is the crux to relieve urban traffic jam. After analysing the features, applicable conditions and functions of the intersection channelization design, the basic procedures based on traffic survey, channelization design of the intersections and as...

In recent years, autonomic and organic computing have become areas of active research in the informatics community. Both initiatives aim at handling the growing complexity in technical systems by focusing on adaptation and self-optimisation capabilities. A promising application for organic concepts is the control of road traffic signals in urban areas. This article presents an organic approach ...

The Beijing road traffic system, as a typical huge urban traffic system, provides a platform for analyzing the complex characteristics and the evolving mechanisms of urban traffic systems. Based on dynamic network theory, we construct the dynamic model of the Beijing road traffic system in which the dynamical properties are described completely. Furthermore, we come into the conclusion that urb...

From now to 2030, the world urban mobility will increase by 50%. This increase will be mainly performed in developing countries which already suffer from congestion traffic especially in large cities where road traffic reaches a high density. This situation leads to a serious impact on the economic and social growth. The urban traffic management has become an essential factor. Within the framew...

This paper describes construction of discrete urban traffic simulation model based on NagelSchreckenberg’s cellular automata model (NaSch model) and its modification. These NaSch models have been constructed for simulation of traffic on highways and freeways. We try to modify this aproach to obtain a model of urban traffic. The development is based on an object oriented approach.

1 Dynamic Traffic Management In urban areas, the infrastructure often represents a bottleneck due to traffic demand exceeding available road capacities. Here, dynamic traffic management is necessary in order to provide strategies for efficient control, e.g. by applying time-dependent signal plans. The traffic load typically varies strongly throughout the day. Therefore an adaptation of the traf...

A common way of dealing with large urban transport infrastructures is by using Urban Traffic Management and Control (UTMC) systems [1][2]. The UK Department for Transport led Urban Traffic Management and Control initiative recognizes the following common UTMC components: strategic network management, comprehensive performance monitoring, traveller information, congestion monitoring, streamlined...

This study was carried out to analyze the variations of Benzene, Toluene, and para- Xylene (BTp-X) present in the urban air of Delhi. These pollutants can enter into the human body through various pathways like inhalation, oral and dermal exposure posing adverse effects on human health. Keeping in view of the above facts, six different locations of Delhi were selected for the study during summe...

Mitigating traffic congestion on urban roads, with paramount importance in urban development and reduction of energy consumption and air pollution, depends on our ability to foresee road usage and traffic conditions pertaining to the collective behavior of drivers, raising a significant question: to what degree is road traffic predictable in urban areas? Here we rely on the precise records of d...
