The interstate highway system carries nearly 60,000 daily person miles per route mile, 26 times as many person miles per route mile as all other roads (including low usage rural roads), and 22 times as many person miles per route mile as intercity rail (Amtrak) and urban rail combined.
The expected urine output for an adult is 0.5ml/kg/hr. This roughly equates to 30-40ml per hour in an average sized adult.
If we were to base the normal urine output to an average adult person, then we could expect to have a result that is 0.5ml/kg/hr. This would give us a rough estimation of about 30 to 40 ml per hour. For children, the output rate is about 1ml/kg/hr. As for adults, some references do consider the same rate of urine output with children. This is because the rate 0.5ml/kg/hr is already considered the low normal amount.
