The present work investigates a Dynamic Vehicle Allocation problem (DVAP) which is faced by major forwarding companies active in road transportation. A company owning a limited fleet of vehicles wants to maximize its operational profit over an infinite horizon divided into equal periods (days). The profit stems from revenues for transporting full truckloads (FTL) and from costs derived from wai...

Policies that stimulate active transportation (walking and bicycling) have been related to heath benefits. This study aims to assess the potential health risks and benefits of promoting active transportation for commuting populations (age groups 16-64) in six European cities. We conducted a health impact assessment using two scenarios: increased cycling and increased walking. The primary outcom...

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...

Creating cities that promote sustainable lifestyles is a complex and far reaching process. One of the most important components of sustainability on an urban scale is the need for an efficient public transportation system, which provides enough convenience that, combined with walking, can be more desirable for residents to use over driving a car. Vehicular traffic congestion is one of the great...

Urban mobility is a problem that affects all cities. Providing real time information that can assist citizens on planning their trips by choosing times and itineraries more appropriate to their needs are essential on smart cities. Our project, named UbiBus, investigates how Computational Context and Ubiquitous Computing can be applied to Intelligent Transportation Systems to aid bus passengers ...

At the closing of the second millennium our civilization can boast a remarkable progress in technological developments which have been growing at an exponential pace. Telecommunications, jumbo-jets and personal computers have become ubiquitous in many countries in recent decades. In the "softer" area of managing complex systems, and even more so in economic, social and ethical aspects, our achi...

Bus transportation is the most convenient and cheapest way of public transportation in Indian cities. Due to costeffectiveness and wide reachability, buses bring people to their destinations every day. Although the bus transportation has numerous advantages over other ways of public transportation, this mode of transportation also poses a serious threat of spreading contagious diseases througho...

Previous urban sprawl studies have typically taken a cross-sectional approach without examining how sprawling urban areas are performing over time. Longitudinal studies of individual or household travel behavior and built-environment preference have made some progress in this direction, but very few studies have explored the longitudinal interaction of urban form with transportation and environ...

We investigate the role of industrial structure in labor productivity growth in U.S. cities between 1880 and 1930 using a new dataset constructed from the Census of Manufactures. We find that increases in specialization were associated with faster productivity growth but that diversity only had positive effects on productivity performance in large cities. We interpret our results as providing s...
