today’s, a common problem in cities is increasing delay and reducing the speed of traffic. on the other wise increasing costs of acquisition in urban area are not allow new routes and highways. also construction of new highway or street such as imam ali highway and sadr highway in tehran lead to develop new applications (such as brt lane ,…) and become quickly saturate and less efficient. there...

Short term prediction of traffic flow is one of the most essential elements of all proactive traffic control systems. Although various methodologies have been applied to forecast traffic parameters, several researchers have showed that compared with the individual methods, hybrid methods provide more accurate results . These results made the hybrid tools and approaches a more common method for ...

environmental pollution of soil, plants and deposits around highways endanger urban environment through heavy metals as the by-products of vehicles and urban industries along with other pollutants. in this research, three main highways of tehran city; namely shahid chamran, shahid hemmat and yadegar emam which had the highest rate of vehicle transportation were selected and required sampling wa...

Road Traffic Accidents are a major cause of disability and death throughout the world. The control of intelligent vehicles in order to reduce human error and boost ease congestion is not accomplished solely by the aid of human resources. The present article is an attempt to introduce an intelligent control system based on RFID technology. By the help of RFID technology, vehicles are connected t...

An important task for progress in IVHS (Intelligent Vehicle Highway Systems) is the development of methods for real-time traffic scene analysis. All three major applications of IVHS ADIS (Advanced Driver Information Systems), ATMS (Advanced Traffic Management Systems), and AVCS (Automated Vehicle Control Systems) could benefit from accurate, high-level descriptions of traffic situations. For ex...

The purpose of this study was to investigate traffic flow characteristics at off-ramp junctions in Iranian expressways. The study was conducted on the traffic behavior in isolated off-ramp vicinity of 6-lane expressways. The database consisted of traffic flow and traffic speed information extracted from videotapes. The relationship between diverging traffic flow in the right lane of expressway ...

In this project, we first planned to model a manufacturing system using a partial differential equation (PDE), since in the theory of traffic simulation and control, PDEs are used successfully for modeling the dynamic behavior of highway traffic. Because these traffic models show good correspondence with manufacturing systems (vehicles = products, highway = manufacturing system), PDEs can also ...

Significant inspiration of computer network topology and communication comes froman empirical understanding of how road networks function. This project takes foundational work by CHESS researchers in hybrid systems to investigate a macroscopic switching-modemodel (SMM) of traffic. The goal is to learn how hybrid systems are used for trafficmodeling, experiment with different techniques for reac...
