To determine

The traffic characteristics with each of the levels of service for primary freeway sections.

Expert Solution & Answer

Explanation of Solution

Introduction:

Level of service is a qualitative method which is used to describe the operating conditions of a given freeway segment. This method uses density as the variable and alphabetic grading system raging between A to F.

There is 6 basic level of service, which is described below.

Level of service A.

The vehicles move freely within the traffic stream without any interruption. Effect of incidents or point breakdown is easily absorbed.

Level of service B.

Traffic moves under reasonably free flow condition with minimum restrictions. Effect of incidents or point breakdown is easily absorbed.

Level of service C.

The speed of the vehicles is almost equal to free flow speed, but the free flow of the vehicles is constrained. The driver has to be cautious while shifting lanes. Small incidents are absorbed but large incidents direct to queuing of vehicles.

Level of service D.

In the traffic stream, the free movement of vehicles is very much restricted, and there is no level of comfort. Even a minor incident leads to queuing of vehicles.

Level of service E.

There are no good gaps between the vehicles, and the operations are unbalanced. The entry of vehicles from ramps or sub-lane leads to a blockage in the traffic flow.

Level of service F

Conclusion:

There are six levels of service which are represented alphabetically from A to F. Level of service A being the ideal for driving with decreasing free flow and level of service F being congested.

Consider a pool of saturated water at atmospheric pressure. The base of the pool is made of thick polished copper square plate of length 1 m. To generate steam, exhaust gas is flowing underneath and parallel to the base plate with velocity 3 m/s and average temperate of 1090°C. The bottom surface the plate is at constant temperature of 110°. Use the properties of air for exhaust gas. a) Determine the boiling heat transfer rate. b) Determine the temperature of the top surface of the plate. Comment on the results. c) Examine the impact of your assumptions on your solutions. (what will change if any of the assumptions is not valid?)

Assume this foundation is being designed for a warehouse that had a thorough preliminary soil exploration. Using the general bearing capacity equation: a. Calculate the gross applied bearing pressure, the gross ultimate bearing pressure, and determine if the foundation system is safe using a gross bearing capacity ASD approach. Please include the weight of the foundation, the weight of the backfill soil, and the effect of the uplift pressure caused by the presence of the water table in your bearing capacity…
