The 85th Percentile Average is a nationwide and PennDOT utilized system on determining the appropriate speed for any section of highway. They look at this percentage in comparison to the posted speed limit (25mph) to see how many vehicles are traveling within the posted speed limit and the 85th percentile average to see if the posted speed is correct for the specific area of highway. Looking at both East and Westbound on West Monument Avenue, the 85th percentile is 27.0 mph/26.0 mph.
Based on the above data it has been determined speed is not an issue on this section of highway. Due to the Moreland Ave Bridge closure, there has been a noted increase in traffic volume on W. Monument Avenue.
