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.

A six-lane highway (3 lanes in each direction) is to be designed to replace an existing highway. The present AADT in one direction is 6000 and is expected to grow at 3% per year. The design life is 30 years and the vehicle mix is: Passenger cars (2000 lb/axle) = 60% 2-axle single unit trucks (6000 lb/axle) = 30% 3-axle single unit trucks (12000 lb/axle) = 10% 1) Determine the design ESAL using the AASHTO method. Exclude passenger cars. Assume SN = 4 and pt = 2.5. 2) Determine the design ESAL using CALTRANS method. Exclude passenger cars. Compare and comment on the result obtained from Problem 1. Calculate the Traffic Index using Caltrans Method. 3)
