Recent advances in the electromobility of bus fleets improve transit service sustainability but require development vehicle recharging facilities. The paper defines a methodology to design an efficient network operated by battery electric buses cities with grid-shaped road network, based on continuous approximations. An analytical model optimal configuration that minimizes agency cost, monetiza...

Temporal coordination of services, as a crucial aspect of integration in public transport systems, has always been a big concern for transit planners and schedulers. One of the major issues in the way of coordinating transit services is the lack of a robust measure of effectiveness for assessing the quality of temporal coordination in public transport systems. Even though the network-wide summa...

Bus rapid transit is an innovative, high capacity, lower cost public transit solution in metropolitan cities. Idea is to dedicate lanes for quick and efficient transport of passengers to their destinations. In the present investigation the environmental impact assessment of bus rapid transit  in Tehran metropolitan city is brought out. For this purpose bus rapid transit Lane No. 10 is investiga...

Gamma-scintigraphy is applied extensively in the development and evaluation of pharmaceutical delivery systems, particularly for monitoring formulations in the gastrointestinal and respiratory tracts. The radiolabelling is generally achieved by the incorporation of an appropriate radionuclide such as technetium-99m or indium-111 into the formulation or by addition of a non-radioactive iso...

The Western Mediterranean basin is a busy route by Short Sea Shipping with an important between Barcelona (Spain) and Genoa (Italy), where climatic patterns show similarities but vary during the year. One essential topic for competitiveness time because distances use to be covered in approximately 24–30 h. To optimize transit time, meteorological variables must kept mind. In this contribution, ...

In this paper, we deal with the locational analysis of Cova Eirós site (Triacastela, Lugo), occupied from Middle Palaeolithic to present. From GIS and statistics, intend approach those environmental factors that define its importance as a place occupation over time on recurring basis. Once have analysed variables characterize site’s patterns use, verified is an important, prominent strategic po...
