URBAN TRANSPORTATION IN IRAN METROPOLITANS

CONGRESS - DUBAI 2011 (2011)

Mohsen Hashemi

Please note that due to the size of the video included wit this presentation, it has not been available yet to upload it . Iran has at least 9 large populous cities (each above 1 million) with sum of 20 million inhabitants. Tehran, Mashhad, Esfahan, Ahwaz, Karaj, Tabriz, Kermanshah, Qom and Shiraz are the largest Iranian cities in which millions of citizens travel everyday to their workplaces, schools, universities, shopping centers and vice versa.Tehran, the Capital of Iran and other Iranian metropolitans are badly suffering from congestion, air pollution and other aftereffects of the daily motorized urban and suburban trips of their inhabitants. The already dangerously polluted living environment would certainly worsen if the current trend of motorized mobility of these sprawling and populated cities continues. Congestion and traffic jams waste the otherwise productive time of citizens while the pollution related diseases are ruining citizens' lives and national wealth. Fortunately the Iranian officials and decision-makers have recognized the importance of boosting public transport in not only easing the condition of everyday lives of the citizens but also in creating jobs, socio-economic development and in one word , better safeguarding national interests. To this end more than 990 km of heavy and light metros and regional rail links have been planned to be implemented in the above mentioned Iranian cities till 2020.The very successful experience of Tehran Metro has strengthened our determination of implementing our ambitious goal of absorbing some 40 percent of Tehran inhabitants' daily trips to urban railway system by 2030. For the time being, in addition to the recently mobilized extensions to the existing metro lines, new lines are under construction. Tehran metro success has also become the paradigm for any comprehensive urban development plan in Iran. Any new Iranian urban development plan considers urban railway system as the backbone of its structure

Phase 1 Completed, but the Target is 370 km by 2020

Mohsen Hashemi

This article describes Tehran’s new metro and railway system. The first phase, covering close to 90 kilometers, is now in operation and construction has begun on the second phase. According to a final development plan, there could be a total of eight metro lines and five electrified suburban lines by 2020. The population of Tehran is currently eight million, but it is growing by more than one percent annually. Suburban areas near the capital bring that number to nearly 11 million people. The first phase of the project includes two metro lines and a suburban line to Karaj and Mehrshahr. Phase two aims to create two more cross-city metro routes and extend the existing lines bringing the total length of the metro to 123 kilometers. The article describes how construction is funded, what type of rolling stock has been purchased, and control and communications of the system.

Study on Learning Techniques for Text Classification

A. M. Mohammad Behrouzian Nejad Bassel Yasser Sayed Mohsen Hashemi C. Javad Chaharlang

Data mining is a one of most popular technologies to information management. One of the most important our data, is text document. We can sort and classify these text documents by data mining techniques. Text classification is a technique to sorting text documents. Basic steps in text classification are preprocessing of documents, feature extract/ selection, selects learning algorithm and evaluation. When we want to classify text documents using computer systems and machine learning techniques, one of the most important steps in text classification is selecting a learning algorithm. In this paper we review some effectiveness learning algorithm researches and show review results of these in a table form.

Keeping Costs Low and Traffic Moving with the Tehran Metro Extension

Public transport international (2006)

Mohsen Hashemi

This article provides an overview of Tehran metro system, which currently operates two lines totaling 90 km. A significant expansion of the system is underway to add three rail lines. The project's construction methods, rolling stock, voltage systems and signaling/control/communication systems are described. The expansion will bring the total of urban and suburban metro lines to 200 km. It is projected that the extension would boost the metro modal share from 10% to 25% by 2012. Tehran Metro will use a transit-oriented development approach. Investment shares are being divided between the central government, the municipality and the private sector.
