This article highlights the relationship between sustainability (or maintainability) and efficiency of transport systems. It also outlines some of the problems and issues that exist in providing mobility to urban Indians. Finally, it enumerates some of the ways in which application of (modern) information and communication technologies can help improve the efficiency of the transportation syste...

The goal of the ramified optimal transport is to find an optimal transport path between two given probability measures. One measure can be identified with a source while the other one with a target. The problem is well known to be NP–hard. We develop an algorithm for solving a ramified optimal transport problem within the framework of Bayesian networks. It is based on the decision strategy opti...

BACKGROUND The purpose of this systematic review was to determine the relationship between a wide range of physical environmental characteristics and different contexts of active transportation in 6- to 12-year-old children across different continents. METHODS A systematic search was conducted in six databases (Pubmed, Web of Science, Cinahl, SportDiscus, TRIS and Cochrane) resulting in 65 pa...

This paper surveys the theoretical and empirical literature on the relationship between the spatial distribution of economic activity and transportation costs. We develop a multi-region model of economic geography that we use to understand the general equilibrium implications of transportation infrastructure improvements within and between locations for wages, population, trade and industry com...

This paper develops, through a simulation model, a deeper understanding of the relationship between transportation infrastructure strategy development frameworks and system performance. A strategy development framework for transportation can be characterized by the infrastructure ownership structures, cross-modal and cross-sectoral linkages, revenue sources, resource allocation decision-making ...

This paper describes the work and results of the second phase of research sponsored by the Federal Highway Administration (FHWA) initiated to study the relationship between traffic activity and ambient PM2.5 concentrations. The study, entitled “Estimating the Transportation Contribution to Particulate Matter Pollution”, had the objective of performing a correlation analyses on particulate matte...

In this paper, we consider the relationship between supply chain network equilibrium and transportation network equilibrium. We demonstrate that a supply chain network equilibrium model introduced earlier can be reformulated as a transportation network equilibrium model with elastic demands through a supernetwork reformulation of the former. This equivalence allows us to transfer the wealth of ...

As the recent development of the Physical Internet contributes to a more efficient usage of transportation and logistics technologies, the question arises whether these technologies may have a varying impact on countries’ economic performance. Thus, it is crucial to understand the drivers of transportation volume. In this paper we present a country-level analysis of the determinants of growth o...

This paper presents an analysis of the topology of transportation networks within different systems of cities. Urban entities and their components are complex systems by their nature; there is no central force that affects their spatial structure. Thus, we study transportation networks within different countries as complex networks. Based on the above, we consider cities as nodes, while direct ...
