An investigation of gaseous elemental mercury concentration in atmosphere was conducted at Beijing and Guangzhou urban, Yangtze Delta regional sites and China Global Atmosphere Watch Baseline Observatory (CGAWBO) in Mt. Waliguan of remote continental area of China. High temporal resolved data were obtained using automated mercury analyzer RA-915+. Results showed that the overall hourly mean Hg0...

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...

This paper presents a study about the Longley-Rice model and its applicability in urban settings located in tropical areas. For this, the model has been modeled computationally for MatLab platform. The LRM (Longley-Rice Modified) algorithm has been calibrated and validated with reference values for analysis of the radio signal attenuation measured in Belo Horizonte. These data are evaluated for...

Urban agriculture is recently being recognized as a distinctive urban land use contributing to greenspaces and food security. The land inventory forms the critical first step in identifying sites for urban agriculture. The authors’ analysis greatly expands on prior land inventory strategies, first analyzing land cover to identify all open areas available for siting urban agriculture. Then in GI...

Pressures for urban redevelopment are intensifying in all large cities. A new logic for urban development is required – green urbanism – that provides a spatial framework for directing population and investment inwards to brownfields and greyfields precincts, rather than outwards to the greenfields. This represents both a major opportunity and a major challenge for city planners in pluralist li...

As typical turn by turn systems fail in several aspects to provide an engaging experience to pedestrians in urban environments, we investigate the potential of alternative interaction methods for navigation. We present a two-phase experiment, involving both audio and tactile navigation and discuss the collected evaluation data. Our findings show a positive reception of implicit navigation from ...

Land surface temperature (LST) is an important parameter to study in urban climate. The understanding of the influence of biophysical factors could improve the establishment of modeling urban thermal landscape. It is well established that climate hold a great influence on the urban landscape. However, it has been recognize that climate has a low priority in urban planning process, due to the co...
