Various traffic parameters required to perform traffic congestion analysis comprise total travel time, average speed, congestion index value, moving time, proportion stopped time that were collected from the field.
Determination of congestion index value and average speed
Congestion index value and average speed can act as significant indicative parameters to assess the status of congestion in different routes of the study area.
Fuzzy concept for categorization of the congestion index values into different classes of congestion
The objective of the present research is to determine the real status of congestion in the study area.
Application of fuzzy concepts for determination of congestion status.
In this paper, two weighted sets were constructed namely congestion (C) and average speed (A).
After assigning weights to the congestion and average speed set, fuzzy union operation was performed between the weighted values of the congestion and average speed set.
The two different sets were used in this paper in order to categorize the congestion status into different classes.
