# Transportation Econonomics

In a box model, the maximum distance to transport particle across a city is shown as D. If the approximate length of one side is 40 miles, width is 28 miles and the mixing height is 2miles, to the nearest mile what will be this distance? ____

In a box model, the maximum distance to transport particle across a city is shown as D. If the approximate length of one side is 40 miles, width is 28 miles and the mixing height is 2miles. For a pollutant particle emitted on one side of the town, what is the maximum time it will take to be transported across the city with wind velocity of 8 miles per hour (to the nearest hour)? ____ (20 points)

If you are the planning engineer for an apartment complex your organization plans to build close to the highway and you know that your potential tenants will complain of traffic noise hazards. You want to assure them that you have adequately carried out the noise impact analysis. Given that the sea level pressure is 0.00002N/m, to ensure that pressure level does not exceed 10 decibels, the sound pressure of concern must be___________ (in N/m). ____

In the Rocky Mountain region, there are endangered species like jumping mice and burrowing owls that are protected by the EPA. If you want to build a roadway to facilitate traffic congestions in Denver, part of your plan will include using Simpsonâ€™s diversity index to calculate the number of organisms in two communities. If EPA warned you that there are 300 burrowing owls in proposed region Community A and 300 burrowing owls in proposed region Community B, determine Simpsonâ€™s diversity index for community A. ____(20 points)
