Instructions and help about Vehicle Delay And Queue Storage

the level of service or Los is a term that's used to qualitatively describe the conditions of a roadway and it can be a variety of factors speed travel time delay safety density of the vehicles could be a number of things but in the case of intersections we're specifically going to talk about in this case we want to look in particular about the delay as the primary measure of the level of service for an intersection level of service is on a scale from a to F where a is the best and F is the worst for a signalized intersection we're going to look at the control delay for that location this is in seconds per Vehicles we're looking at the average control delay and control delay just means the delay that's caused by that signal so for level of service a that's a delay less than or equal to 10 seconds for level of service B between 10 and 20 for C 20 and 35 for D 35 and 55 E 55 to 80 and F greater than 80 seconds per vehicle of control delay now from a general description perspective a is f
