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 designing a freeway as a passenger-car only facility, and with ideal roadway characteristics. It is estimated that the freeway will have a traffic demand of 75,000 vehicles per day, a free-flow speed of 70 mi/h, a traffic stream of primarily commuters, a peak-hour factor of 0.88, and a directional distribution of 0.65. Determine the number of lanes (both directions) required to provide at least LOS D using the 30th highest annual hourly volume (K30 = 0.12). The answer is a/an -lane freeway.

A section of a two-lane rural highway is expected to have the following characteristics: Design speed of 80 km/hr, lanes of 3.6 m, walks of 1.2 m, mountainous terrain, 70% of sections without passing distance and length of 7 km. Of traffic 1,321 veh/hr: distribution by direction of 60/40, 10% of trucks, 10% of buses and 80% of light vehicles. Say what is the capacity of the section and the maximum intensity for the NS
A segment of rural freeway is being designed for a FFS of 70 mph through rolling terrain. The directional (i.e. one-way) design volume is 3,000 vehicles per hour. If 10% of the design volume is expected to be heavy vehicles (i.e. trucks and buses), what is the heavy vehicle adjustment used to determine the flow rate? Provide you answer to the nearest hundredths.

It is estimated that after 25 years in a section of highway, the average daily traffic will be 15000 vehicles. It is found that ratio of design hourly volume to the average daily traffic was 15%. The one way traffic volume in the predominant direction is 60% of the two way design hourly volume. Determine the directional ?design hourly volume after 25 years **
A new section of a freeway is to be designed with a free-flow-speed of 65 mph along of 0.75 mile on 5% upgrade. The expected traffic volume is 4200 v/hr. The traffic composition is 15% trucks, 5% recreational vehicles, and 10% buses. The peak hourly factor is 0.9, the unfamiliar driver factor is 0.95. If the design requirement is to target a level of service (B), how many lanes must be provided to satisfy the design requirement?
