urban settlements and their connectivity will be the dominant driver of global change during the twenty-first century. in an attempt to assess the effects of urban growth on available land for other uses and its associated impacts on environmental parameters, we modeled the change in the extent of gorgan city, the capital of the golestan province of iran. we used landsat tm and etm+ imagery of ...

Nowadays, urban traffic congestion is a complicated and ubiquitous problem. Continuous changes of traffic congestion with respect to the time lead to change the travel times of transportation network. These changes show the importance of time in transportation analyses in addition to the location. So determining the optimal path in a time-dependent transportation network is a challenging task.T...

establishing a network of transit routes with satisfactory demand coverage is one of the main goals of transitagencies in moving towards a sustainable urban development. a primary concern in obtaining such anetwork is reducing operational costs. this paper deals with the problem of minimizing construction costsin a grid transportation network while satisfying a certain level of demand coverage....

With an increasing deployment of plug-in electric vehicles, evaluating and mitigating the impacts of additional electrical loads created by these vehicles on power distribution grids become more important. This paper explores the use of prices of electricity at public charging stations as an instrument, in couple of road pricing, to better manage both power distribution and urban transportation...

1- introduction transportation and traffic is one of the major issues and challenges that are facing urban managers. so that it has become one of the major challenges in the political area. transport is one of the most important elements of urban development which is used for people and goods moving from a different geographical place to other places. in order to achieve efficient productive in...

I nrecent years there has been a noticeable shift away from the application of computer-based transportation modeling methods in smallto medium-sized urban areas. In many cases, this shift has resulted from a disenchantment with the complex modeling methodologies used in the late 1960s and early 1970s. The expense of such methods, in terms of data collection and computational costs, was simply ...

Recently, new approaches with commercial high-resolution satellite imagery in the engineering application domains have been attempted. Among them, uses of remotely sensed imagery linked with GIS-T (Geographic Information Systems for Transportation) or transportation geography are regarded as one of prospecting issues. As the matter of facts, most transportation applications are needed real-time...

New transportation systems have always attracted attention of both transportation experts and general public: the first railway in England, first automobile and streetcar in Germany, first airplane in the United States all of these inventions attracted excitement, curiosity, enthusiasm and skepticism. With time, many inventions fulfilled or exceeded expectations: they have been developed into m...

In this work we present a large scale static, deterministic mixed inter linear programming model (MIP) solving an integrated location-routing problem (LRP) in the context of urban logistics services (ULS). We aim at determining a cost optimal infrastructure and fleet design for an urban consolidation and transportation network. The model is meant to quantitatively evaluate potential strategic m...

Urban traffic plans (UTPs) are tactical planning tools for managing urban areas and traffic noise abatement is one of their objectives, explicitly provided for under Italian law. To date, the various models and methods for estimating traffic noise have concerned its estimation in a point (or on a road segment). In this paper we propose a method that is able to evaluate the effects of UTPs on no...
