The main contribution of this paper is that the limitations of the planar manifold assumption, which is adopted in previous low-energy orbit design methods, are avoided by describing the transfer orbits with more realistic spatial transit and non-transit orbits.
By explicitly capturing multimodal transfer activities and cost implications with virtual transfer nodes and arcs, this study models transit hub as a realistic transportation infrastructure rather than a single node in the network.
Herein, we extend the analysis to account for a more realistic case: a transit system with a hierarchical structure (trunk and feeder lines) providing service to a city where demand is elastic.
Is it realistic to expect transit and school bus drivers to remain in the city until mandatory evacuation is ordered, or will they have moved with their families out of the city during the voluntary evacuation phase?
Just two years ago, the State Transportation Department said, "Mass transit offers the only realistic means of addressing the requirements of improving mobility in the corridor".
A variable demand case is considered as it replicates a realistic scenario for planning a rail transit line.
The comprehensive optimization of the timetables of urban rail transit systems under more realistic conditions is essential for their practical operation.
As much as we'd like to think so, until there is a fast north/south mass transit connection as well, it's just not realistic to expect that most Valley and South Bay commuters will be taking mass transit to the subway.
For simplicity, we described the distribution of capillary transit times across the capillary bed by a realistic distribution, for which CTH is simply the standard deviation of capillary transit times, whereas the mean erythrocyte transit time (MTT) is given as the capillary blood volume fraction divided by TBF.
With this, and the carrier transit times deduced from field-effect transistor experiments, a realistic value of 200 for the photoconductive gain was deduced.
