IN FR A STR U C TU R E The condition of the nation’s infrastructure has been the subject of several major studies in recent years. As could be expected, Canada has similar problems concerning the condition of the infrastructure. Needs studies undertaken from the late 1970s to the present suggest four major conclusions: the nation’s infrastructure has been maintained unevenly; many public facili...

In an urban city, its transportation network supports efficient flow of people between different parts of the city. Failures in the network can cause major disruptions to commuter and business activities which can result in both significant economic and time losses. In this paper, we investigate the use of centrality measures to determine critical nodes in a transportation network so as to impr...

One of the current challenges in urban planning concerns the urban transportation involving multi-mode transportation. One of the ways to evaluate different situations in order to make decisions of how, when and where to invest is using multimodal traffic simulation. This paper presents a review about multimodal traffic simulation, identifying the state of art and directions for future work. Ke...

Today, urban transportation has attracted urban planners’ and researchers' attention because of air and noise pollution problems associated with it. In Shahrkord city in Iran, no plans have been made for sustainable transportation, and the available poor transportation infrastructure is not responsive to the growing population of the city. This issue has inflicted the city with serious problems...
