A vertical curve was designed in 2005 for SSD requirements at a design speed of 120 km/h to connect grades G1=+2% and G2=-3%. The curve is to be redesigned for the same design speed in 2025. Vehicle braking technology has advanced such that the vehicle deceleration rate has increased by 40% relative to the value used in the original design. However, due to the higher percentage of older people in the driving population, design reaction times have increased by 20%. Compute the difference in design curve lengths for the 2005 and 2025 designs based on Australian guidelines.
