A) In a signalized intersection with three legs, the north phase has two movements: left turn movementwith the one-lane approach and through movement. Evaluate the saturation flow rate of eachmovement. If the environmental condition is bad, and the continuous uphill gradient is 1%. Theapproach width for the through movement is 24 ft. (assuming: no on-street parking, no bus stops.and negligent bicycle and pedestrian traffic conflicting).B) Briefly describe the factors that controlled a selection of a transportation project and the role of thehighway engineers. Then explain how to translate the project's ability objectives to solve theproblem into criteria.C) Two alternatives have been proposed to construct a new road project to improve capacity andsafety. The table below explains each alternative's costs: the initial construction costs, annualoperating and maintenance costs after the first year, and resurface of road costs. Assume that theannual interest rate is 5%. Determine the present worth for each alternative, then choose thepreferred alternative based on the economic criteria.AlternativeThe initial construction costsThe annual operating and maintenance costsThe resurface costsService life (years)$4,000,000$3,900$850,000(Every five years)142$3,800,000$4,100$800,000(Every four years)

The yearly transition probabilities of various condition states of deck component of bridges on urban Interstate highways in a U.S. state are given in Table 1. In 2018, there are 1771, 2751, 1771, and 578 bridges in the Excellent, Good, Fair, and Poor condition states, respectively. Find the number of bridges that are expected to be in the Excellent, Good, Fair, and Poor conditions in 2022. Assume that no major repairs were done during the period, so the original transition matrix stays unchanged
According to a construction company plan, a project must be implemented in three consecutive stages during six months. The chance that the first stage is completed on time is (0.5). The chance that the second stage is completed on time is (0.3) given that the first stage is completed on time. The chance that the third stage is completed on time is (0.2) given that both the first and the second stages are completed on time. Accordingly, the probability will be equal to (1) when all three stages .are completed on time True O False O
