The Vehicular ad hoc network (VANET) is an emerging new technology. Developing multi-hop routing protocols for urban VANETs is a challenging task. VANET is one of the influencing areas for the improvement of Intelligent Transportation System (ITS) in order to provide safety and comfort to the road users. Besides safety applications VANET also provide comfort applications to the road users. Auto...

The development of sustainable urban transport networks is a present priority for world leaders, national governors and local authorities. The challenge is to increase mobility reducing the adverse impacts of transport. The potential of Intelligent Transportation Systems (ITS) to provide solutions for the 21 century sustainable urban transport system has already been demonstrated in several pie...

This interdisciplinary seminar brought researchers together from many fields including computer science, transportation, operations research, mathematics, machine learning and artificial intelligence. The seminar included two formats of talks: several m...

Problem of traffic jams is common in large cities. Urban traffic control systems aim to solve this problem. The major difficulty in urban traffic is large number of variables for representing the state of traffc, such as traffic flow,speed, and density. Lack of precise relations between these variables is another problem. In this paper, we present a new model for traffic flow and introduce a tr...

In recent years popularity of private cars is getting urban traffic more and more crowded. As result traffic is becoming one of important problems in big cities in all over the world. Some of the traffic concerns are congestions and accidents which have caused a huge waste of time, property damage and environmental pollution. This research paper presents a novel intelligent traffic administrati...

We developed an intelligent geoinformation platform for transport process analysis. The paper describes a purpose and functions of the synthesized platform as well as its structure including components and tools. We used the intelligent transport geoinformation platform for solving problems of acquisition, storage, processing and analysis of objects, processes and phenomena of urban transport i...

Cybernetic Transportation System (CTS) is a new branch of Intelligent Transportation Systems (ITS), which is a solution to the urban transportation problem. The coordination of intelligent vehicles is critical for the operation of the Cybernetic Transportation System. We present a distributed coordination approach for the intelligent vehicles of the Cybernetic Transportation System, which is ba...

Background: Coronary heart disease (CHD) is a significant cause of health and economic burden. Secondary prevention programs play a pivotal role in the treatment and management of those affected by CHD although participation rates are poor due to patient, provider, health system and societal-level barriers. As such, there is a need to develop innovative secondary prevention programs to address ...

noise pollution can be considered as the most important problem of urban environmental management in mega metropolises and urban transportation is the main source of the mentioned problem. this study aims to investigate the amount of traffic noise dose received by traffic policemen in tehran; district 1 municipality. the investigation was conducted during three consecutive months in 2007 in 282...

environmental protection is a key element in urban management. due to complex relationships between human and environment in metropolises the importance of environment is ever-increasing. in this paper the current situation of environment in tehran metropolis including air, water, biodiversity and human habitat along with the most crucial threats, their effect as well as the associated agencies...
