This study examines the dominance of the D/H ratio as a design element for an enclosed urban square, long claimed by numerous urban designers. It claims that like the D/H ratio, other design elements significantly affect the perceptual quality of an enclosed square, but their impacts differ according to the context in which they are applied. The study reviews the literature pertaining to enclos...

The rich identity, originality and validity of the “Ancient Iranian Urbanism and Architecture”, always have been stimulating the urban designers and planners to have research about their valuable qualities and historical principles. Unlike the past, today’s Iranian cities have inefficient urban qualities; because they are inspired by the western urban designs, without paying attention to their ...

In this project we focuss on intelligent dynamic urban traffic management and control system that can adaptively respond to real-time traffic conditions. In this paper we investigate the usability and aplicability of autonomous intelligent agents, while maintaining high levels of accuracy and usability of such a dynamic urban traffic system. Aim of this part of the research is to develop insigh...

Abstract Digital architecture, as a proceeding architectural style, has caused fundamental evolutions in architectural design and building appearance via applying complex geometries and topologies. Computers and digital tools have truly altered the design process and architectural conception facilitating production of new eye catching forms. Avant-garde architectural forms have emerged from the...

background  & aim: case-crossover  studies are the case-control  version of crossover studies. in these studies, cases and controls are the same subjects. the term crossover is applied for designs that all subjects pass through both treatment (exposure) and placebo (non-exposure) phases. in fact they are  crossover  of  subjects  between  periods  of  exposure  and  non-exposure.  this  design ...

due to the changes which may occur in their parameters, systems are usually demonstrated by some subsystems for different conditions. this paper employs modified petri nets (mpn) to model theses subsystems and makes it simple to analyze them. in this method, first, the continuous transfer function is converted to a discrete transfer function and then, by mpn, system is modeled and analyzed. all...

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 paper presents the Simulator of Intelligent Transportation Systems (SITS).The SITS is based on a microscopic simulation approach to reproduce real traffic conditions in an urban or non-urban network considering different types of vehicles, drivers and roads. A dynamical analysis of several traffic phenomena, applying a new modelling formalism based on the embedding of statistics and Fourie...
