Visualisation and Simulation of Pedestrians at Train Stations
Space utilization by humans is an important aspect in building design, especially for buildings with a substantial flow of pedestrians like train stations. We aim at a simulation of pedestrian flows as a visual feedback in the planning phase of buildings. The simulation has to provide feedback for the layout and dimensions of floor space. This includes the general organization of space as well ...
متن کاملAn Exploration into Younger and Older Pedestrians’ Risky Behaviours at Train Level Crossings
Background: Younger and older pedestrians are both overrepresented in train-pedestrian injury and fatality collision databases. However, scant research has attempted to determine the factors that influence level crossing behaviours for these high risk groups. Method: Five focus groups were undertaken with a total of 27 younger and 17 older pedestrian level crossing users (N = 44). Due to the la...
متن کاملEffect of Rail Corrugation on the Amount of Train Induced Vibrations near a Historical Building
The evaluation and control of the trains induced vibrations needs even more attention in the case of underground tracks which passes near to monuments and historical sites. The rail corrugations which occur due to the wheels’ impulse loads during the operation period of underground railway tracks, usually amplify the ground borne noise and vibration. In the current study, the mentioned phenomen...
متن کاملCFD Simulation of High-speed Trains: Train-induced Wind Conditions on Trackside Installations
Speed is the created air flow as well as slipstream effects as the trains move. These effects can have some level of impact on fuel and energy efficiency of the train, but their other important outcome is the emergence of turbulent flows at higher speeds which can cause aerodynamic drag forces followed by noise and vibration. Thus, slipstream effects have significant importanc...
متن کاملThe pressure disturbance of a nonlinear internal wave train
Observations from a lander fixed to the seafloor over the continental shelf in 124 m of water provide highly-resolved velocity measurements through nonlinear internal waves of elevation. From these measurements we directly determine, for the first time, the nonhydrostatic pressure disturbance (pnh) in nonlinear internal waves. For near-bottom waves of elevation ranging in amplitude (a) from 12 ...
