Determining the impact of volume to capacity ratio on travel time

Travel time on a given highway section is the time taken to traverse that section from upstream to downstream. It has become a useful parameter utilized by both planners as well as road users in evaluating the operational performance of highways and intersections (level of service). However, travel...

Civil engineering (General) Travel time on a given highway section is the time taken to traverse that section from upstream to downstream. It has become a useful parameter utilized by both planners as well as road users in evaluating the operational performance of highways and intersections (level of service).
