Hey all!
Why isn't Intersection Capacity Utilization preferred over HCM LOS? Where I live, PennDOT doesn't allow ICU to be considered in signal design at all.
Wikipedia says:
"Intersection Capacity Utilization (ICU) method is a tool for measuring a roadway intersection's capacity. It is ideal for transportation planning applications such as roadway design, congestion management programs and traffic impact studies. It is not intended for traffic operations or signal timing design."
What makes it ideal for planning, but not signal design?
