  • A Corridor Pilot for Better TrackTime Governance in Indian Railways Policy Brief
    A Corridor Pilot for Better Track-Time Governance in Indian Railways [Policy Brief]
    Shukla, Utsav
    2026-07-01 | PDF
    This study analyzes track allocation as a practical problem of how a busy railway shares limited time on the same track. First, Indian Railways' rules for planning maintenance blocks were reviewed, including the rolling block system and the way line capacity is calculated. This is helpful in understanding how the system is supposed to work on paper ...

  • Modeling Traffic Noise and Light on Natural Landscapes at the State Scale
    Modeling Traffic Noise and Light on Natural Landscapes at the State Scale
    Hodgson, Benjamin ;
    Waetjen, David
    2026-07-01 | PDF
    Anthropogenic noise and light have been shown to impact wildlife behavior, distribution, movement, and population fitness and survival. Traffic noise and light can inhibit wildlife use of areas adjacent to roads, impair wildlife perception of traffic risks, and cause a barrier effect to wildlife occurrence and movement well beyond road edges. A cri ...
