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...

Transportation has historically had a major influence on cities their locations, growth and form. Civil engineers were the leading public servants in construction of railway and transit systems. With diversification of transportation and, particularly, growth of highways, the solutions to urban transportation have become extremely complex. Instead of only building new facilities, it is now nece...

In these days, remotely sensed imagery has been widely used for GIS-T (Geographic Information Systems for Transportation). As for this approach, topological measure and spatial metrics of transportation network structure such as road layer can be considered as one of important factors in urban transportation analysis. Related to this measure, it is known that the connectivity such as alpha inde...

Objective: To improve the reliability of complex urban public transportation network. Methods: Establishing the reliability evaluation system of urban public transportation network. Process: The paper introduces the development of urban traffic construction, describes the characteristic parameters of complex networks, and establishes the model of the reliability evaluation index system of compl...

A city and its transportation network are both complicated systems. Fractal geometry provides an effective way to describe the complex property of geographical features. This paper uses a modified box-counting method to describe the fractal property of urban transportation networks. Assuming that human settlements of different sizes are all operated by the same growth procedure, this paper inve...

We give a model for the description of an urban transportation network and we consider the related optimization problem which consists in finding the desing of the network which has the best transportation performances. This will be done by introducing, for every admissible network, a suitable metric space with a distance that inserted into the Monge-Kantorovich cost functional provides the cri...

walking has always been the most natural, the oldest, and the most essential form of transportation and is still major form of moving, hence, it plays a vital rule in urban transportation. in fact, walking is the most important tool for seeing, being seen, observing city wide daily and social activities, discovering the values and hidden attractions in urban environment, and therefore, feeling ...

Chinese cities are experiencing major environmental e!ects from fossil fuel-based energy consumption for mainly residential and, increasingly, urban transportation uses. Community energy management (CEM) is a sustainable energy strategy which looks at how purposely shaping the built environment and designing urban services in consideration of energy production, distribution and use could a!ect ...
