Chapter 9, Problem 1P

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.

A steel, possessing an eutectoid composition, undergoes a gradual cooling process from 800°C to 600°C. Outline the transformation, equilibrium microstructure, and provide approximate component proportions. Describe the resultant non-equilibrium microstructure in two scenarios: a) the steel is rapidly cooled from 800°C to 600°C within 1 s, and then held at such temperature; b) the steel is rapidly cooled from 800°C to 600°C within 1 s, maintained at this temperature for 5 s, and subsequently quenched to room temperature. Use the provided diagrams. Temperature (°C) 1600 1538°C 1493°C 1400 L 1394°C Y+L 1200- 1147°C 2.14 Y.
