به طور خلاصه آنچه پرداختن به این مطالعه را ضروری می نماید دستیابی به اصول و معیارهای طراحی شهری و طراحی محله های پایدار جهت حفظ ارزشهای سکونتی در محلاتی است که در مجاورت راسته تجاری قرار دارند که در طی دهه های اخیر در مناطق مختلف شهر تهران ایجاد شده و در روند رشد اراضیِ این دسته از بازارها، محله نیز تبدیل به بخشی از آنها می گردند. در راستای جلوگیری از پیش روی بیش از پیش این دسته از بازارها درون ...

Models are commonly used to identify lands that will best maintain the ability of wildlife to move between wildland blocks through matrix lands after the remaining matrix has become incompatible with wildlife movement. We offer a roadmap of 16 choices and assumptions that arise in designing linkages to facilitate movement or gene flow of focal species between 2 or more predefined wildland block...

Today, with progress and developments have been done in motor cars, cars have been produced with high speed and acceleration. But this increasing in speed and acceleration, have caused many concerns about tragic driving accidents and events. Until now, many models have presented about prevention of accidents, in order to reduce these concerns. In this paper, we are going to design a multi agent...

As the problem of urban traffic congestion spreads, there is a pressing need for the introduction of advanced technology and equipment to improve the state-of-the-art of traffic control. As on date Traffic problems are increasing because of the number of vehicles are increasing by leaps and bounds beside the resources available with the current infrastructure are limited. A methodology has been...

The proliferation of mobile technologies makes it possible for mobile advertisers to leap beyond the real-time snapshot of the static location and context information about consumers. In this study, we propose a new mobile advertising strategy that leverages full information on consumers' offline moving trajectories from four different mobility dimensions (i.e., temporal duration, spatial dispe...

Formulating knowledge for use in AI Planning engines is currently something of an ad-hoc process, where the skills of knowledge engineers and the tools they use may significantly influence the quality of the resulting planning application. There is little in the way of guidelines or standard procedures, however, for knowledge engineers to use when formulating knowledge into planning domain lang...

I. Abstract Nowadays people are strongly dependent on cars for doing their tasks, but they usually are not aware of hazards which are awaiting them. For instance, since people travel with cars, their human bodies undergo in fatigue, restlessness, and sometimes health problems. Human body reaction under external vibration depends on the amplitude, frequency, and acceleration of the applied exter...

The existing coordinated control methods of green wave are complicated, difficult to operate and mainly applicable intersection groups with symmetrical arriving upstream flows. Based on engineering practice, a new method bidirectional progression coordination was presented by designing particular overlapping phases the basis NEMA dual-ring phasing configuration. Applying characteristics asymmet...

It is well known that crashes on horizontal curves are a cause for concern in all countries due to the frequency and severity of crashes at curves compared to road tangents. A recent study of crashes in western Sweden reported a higher rate of crashes in right curves than left curves. To further understand this result, this paper reports the results of novel analyses of the responses of vehicle...

Road safety index is an important indicator that has been recently introduced as a useful tool to measure the quality of life in many countries and cities. Road safety index is a complex index and it has at least three main components, including road user behavior, vehicle safety, and road infrastructure effects. Many researchers have selected studying road performance from road safety index pe...
