Freight and passenger transport are two main functions of the infrastructure and transportation networks in each country. It is required to efficiently utilize the transportation infrastructures to increase transportation-related performance measures. In this study, data envelopment analysis (DEA) model is used to evaluate performance of the Iranian provinces from the freight and passenger tran...

We have constructed a framework for analyzing passenger behaviors in public transportation systems as understanding these variables is a key to improving the efficiency of public transportation. It uses a large-scale dataset of trip records created from smart card data to estimate passenger flows in a complex metro network. Its interactive flow visualization function enables various unusual phe...

Energy efficiency is more and important for modern electrified transportation systems, requiring an understanding of the various indexes performance (regenerability, receptivity, energy losses, thus including braking recovered loss in catenary) influence main system parameters (headway, line voltage, substation separation, etc.). By means electromechanical simulation, most relevant conditions a...

This report explores pathways to reducing transportation based carbon dioxide emissions in the United States. The goal is to analyze the feasibility of reducing the level of transportation based carbon dioxide emissions in 2050 to 50% of the level they were at in 2005. Emissions have been steadily rising over the past century, and if left uncurbed, will have a negative effect on the quality of ...

– User-cost indexes provide important information about the welfare implications of durable goods purchases. In this paper indexes for the cost of private transportation are developed, based on the costs associated with using new passenger cars sold in 1992-1999, in the Netherlands. These user costs consist of both fixed costs such as economic depreciation, and operating costs such as fuel cons...

Integrating passenger and freight flows creates attractive business opportunities because the same transportation needs can be met with fewer vehicles and emissions. This paper seeks an integrated solution for the transportation of passenger and freight simultaneously, so that fewer vehicles are required. The newly introduced problem concerns scheduling a set of vehicles to serve the requests s...

The analysis of the structural organization of the interaction network of a complex system is central to understand its functioning. Here, we focus on the analysis of the bipartivity of graphs. We first introduce a mathematical approach to quantify bipartivity and show its implementation in general and random graphs. Then, we tackle the analysis of the transportation networks of European airlin...

The development of a seat reservation system by JNR (Japanese National Railways) named MARS has been sustained by the growth in passenger transportation operations and the progress of computer technology in Japan. But passenger operations of JNR handled only 23 percent of total passenger traffic in 1985 and the growth in the share of JNR is trifling today. Therefore more efficient and economica...

With the expansion of cities and ever-increasing traffic dilemma closely connected to people’s lives, public transportation has become one the essential needs of communities. Subway because of its benefits is an important part of our lives: alleviating urban transit pressure, high safety and reliability, mass transit capacity, low energy consumption, and low price. Therefore, its performance im...
