  • Effect of Passageway Width on Pedestrians Flow Characteristics in Intercity Railway Stations
    Transport and Telecommunication Journal, 2019
    Co-Authors: Eswar Sala, K. V.r. Ravishankar
    Abstract:

    Abstract Rail transportation is most economical means of the mode in comparison to road transportation. Intercity railway stations are nodal points of the rail network. With the growing demand and land use constraints, these are to be well planned, managed and designed. In intercity railways station infrastructure, Passageways are confined and elevated elements for pedestrian movements to access among platforms to alight and board trains. Provision of appropriate width for Passageway is of greater importance regarding comfort, convenient, evacuation, efficient, aesthetic, cost-effective, environment-friendly and well integrated with other elements of infrastructure. A proper understanding of pedestrian flow characteristics and affecting factors on Passageway aids in design implications. In the present work, pedestrian flow characteristics variation on Passageway and its width effect is studied. Results showed that, under normal conditions, flow rate (ped/m/min) and mean walking speed (m/min) reduces with increase in width (m). For a given flow rate, volume (ped/min) of pedestrians served on Passageway increases with increase in width. Statistical tests revealed that there exists a significant difference in mean walking speed of pedestrians on Passageways with different widths.

  • Evaluation of pedestrian flow characteristics across different facilities inside a railway station
    Transportation Research Procedia, 2017
    Co-Authors: Monalisa Patra, Eswar Sala, K. V.r. Ravishankar
    Abstract:

    Rail networks play major role in transporting people at any level of development of a country. Railway stations infrastructures are to be well designed and managed for platform changing and evacuation. A detailed study is to be made in understanding pedestrian flow characteristics on horizontal and vertical movement facilities. In this paper, Passageway with and without centre rail, stairway and escalator are evaluated and compared within a railway station for a keen insight in variation of pedestrian traffic characteristics. Pedestrians speed on stairway is higher than on Passageway. Walking speed of younger is greater than middle aged and elders have less speed. Pedestrians with luggage walk slower than pedestrians without luggage. Significant differences in speed exist with respect to attributes age, luggage, gender and direction. It is interesting to observe that the flow on Passageway with and without centre rail is same. Pedestrians tend to move and merge with flow to the adjacent side of Passageway connected at the neck of stairway.

  • ultraviolet ray tap water disinfection device
    2016
    Co-Authors: Chen Zhiyuan
    Abstract:

    The utility model discloses an ultraviolet ray tap water disinfection device, it contains one and is used for the montage at the body of tap or water pipe, and the body has a rivers Passageway, one sets up the power generation facility in the rivers Passageway, and power generation facility has a rotatable pivot, and one combines the water wheels in the pivot, and one combines the permanent magnet in the pivot, and one sets up the coil module at two sides of permanent magnet or two ends, and an ultraviolet light emitting module that is arranged in the rivers Passageway, ultraviolet light emitting module has a circuit board, and more than one sets up the ultraviolet LED bulb on the circuit board. Therefore, the utility model discloses usable rivers promotion water wheels, water wheels drive permanent magnet again and rotate for the coil module, and then produce electric power and supply with ultraviolet light emitting module, make ultraviolet LED bulb send the water that the convection current of ultraviolet linear light passes through and carry out the sterilization.

  • Evaluation of pedestrian flow characteristics across different facilities inside a railway station
    Transportation Research Procedia, 2017
    Co-Authors: Monalisa Patra, Eswar Sala, K. V.r. Ravishankar
    Abstract:

    Rail networks play major role in transporting people at any level of development of a country. Railway stations infrastructures are to be well designed and managed for platform changing and evacuation. A detailed study is to be made in understanding pedestrian flow characteristics on horizontal and vertical movement facilities. In this paper, Passageway with and without centre rail, stairway and escalator are evaluated and compared within a railway station for a keen insight in variation of pedestrian traffic characteristics. Pedestrians speed on stairway is higher than on Passageway. Walking speed of younger is greater than middle aged and elders have less speed. Pedestrians with luggage walk slower than pedestrians without luggage. Significant differences in speed exist with respect to attributes age, luggage, gender and direction. It is interesting to observe that the flow on Passageway with and without centre rail is same. Pedestrians tend to move and merge with flow to the adjacent side of Passageway connected at the neck of stairway.
