Abstract: At-grade rail crossings, where railway tracks intersect roadways at the same level rather than being separated by bridges or tunnels, are crucial elements of transportation infrastructure. However, these crossings create significant challenges for rail operations, particularly regarding safety and efficiency. Locating an at-grade rail crossing near a road intersection is generally discouraged due to the increased risk of train delays, reduced visibility.......

Abstract: Background: Energy is important to modern life, because it is a critical driver for socio-economic development, especially in developing countries like Nigeria. However, it comes at a price to consumers and at an even greater price to the environment, because of environmental pollution caused by fossil fuels used for energy generation. Therefore, this study assessed energy consumption in Nigerian hospital buildings to determine economic and environmental benefits derivable from its effective utilization.
