Evaluation of Transportation Projects

Civil engineers undertake a variety of projects related to construction. Building construction projects, structural projects, highway, road construction projects, transportation projects, etc. Transportation projects are related to public constructions that focus to build new connectivity in public transportation. To improve and maintain existing transport facilities also falls under the domain of transportation projects. Some of its objectives include planning, evaluation, designing, development, finance, construction, reconstruction, demolition, rehabilitation, improvement, acquisition, operation, and maintenance. As per the law, all transport projects are authorized to the construction firm that permits them to change the land area meant for public use.

You are asked to design a horizontal curve for a four-lane road. The road has 12-ft lanes. Due to expensive excavation, it is determined that a maximum of 47 ft can be cleared from the road's centerline toward the inside lane to provide for stopping sight distance. If local guidelines dictate a maximum superelevation of 8%, what is the highest possible design speed for this curve?
