CONDITIONS: Low : Variable travel times with the majority of the travel time attributed to segments with total resistance less than 4%. Abnormal operating efficiency with significant periods of wait time or delays. Medium : Average travel times with a balance between travel time along routes in excess of 10% total resistance and routes less than 4% in total resistance. Normal operating efficiency with occasional periods of wait time or delays. High : Long travel times with the majority of the travel time attributed to road segments in excess of 10% total resistance. Highly efficient applications with minimum delay or wait periods.
