Explanation of Solution

Introduction:

The level of service is a term that is used to measure the quality of motor vehicle traffic service. The level of service is used for the analysis of roadways and intersection. It categorizes traffic flow and quality of the traffic based on some performance, measures such as traffic density, congestion, and speed.

For the automobile mode, LOS is computed by calculating the level of service at each lane group, intersections, and intersection approach. These are known as a control delay. Control delay is based on the performance measures of the traffic which are determined on the field.

The lane group level of service is calculated by considering both control delay, as well as volume to capacity ratio. But at the intersections, it is calculated only by considering the control delay. Control delay does not represent the consumption of fuel, and the travel time loss.

For the human-powered modes, the LOS is determined by considering the factors that can be described as either performance measures, such as pedestrian delay, and indicator of intersection characteristics as pedestrian corner circulation area, etc.

Conclusion:

Thus, for the automobile mode, LOS is computed by calculating the level of service at each lane group, intersection approach, and at intersections, and for the human-powered modes, the level of service is calculated by considering the pedestrian delay, pedestrian corner circulation area, etc.
