![]() Warrant #3 (Peak Hour Warrant) requires the use of data on "vehicle-hours of delay." How is this data measured and collected?.How can I obtain the formulas on which the curves in the graphs for signal warrants 2 (four-hour warrant) and 3 (peak hour warrant) are based?.Why was a 56% column added to Table 4C-1, and will that make it more or less difficult to install a signal?.Why does the MUTCD allow the signal warrant volumes to be reduced to 70 percent of the normal values in certain conditions?.Where did the numbers come from for the vehicular volume signal warrants in the MUTCD?.If none of the numerical signal warrants are met at an intersection, is there ever any justification for installing a signal anyway?.Doesn't the MUTCD say that other factors beyond just the warrants have to be considered in the decision to install a signal? ![]()
