SPEE DThis is to take Recurring out the delay caused by the lower average speeds from commercial 60vehicles. MPH Recurring Total delay per mile > Delay per mile is calculated by taking the totalAVERA delayGE SPEED and dividing it by the length of the freeway. This was performed for eachNon-recurring route in each county. ACTUAL SPEED User Delay Cost > User Delay Costs (UDC) is calculated by multiplying delay x hourly vol- ume per hourly user cost. Delay is calculated by taking the difference between actual speeds when they fall below 60 mph and the posted speed limit. Hourly volumes are derived from Average Daily Traffic (ADT) and Commercial Average Daily Traffic (CADT). Hourly user costs are based on FederalNorthbou Highwaynd Administration Travel Times (FHWA)Avg publication75th % number95th FHWA-SA-98-079,% “Life-Cycle Cost16.0 Analysis in Pavement Design.” Congestion Severity14.0 > Congestion Severity is calculated based on the worst hourly aver- age speed experienced12.0 Small duringdierence the AM or PM Peak period per traffic Largemessage dierence channel (TMC) segment.

When travel times are unreliable, customers are more likely to experience unexpected delays. Trav- el times are shown to be reliable when the 95th percentile travel time remains close to the average travel time. 75th Percentile Travel Time > The amount of time a customer should budget to be on-time three out of four days (75% of the time). 95th Percentile Travel Time > The amount of time a customer should budget to be on-time nineteen out of twenty days (95% of the time). The 95th percentile travel time is also known as the planning time. 2 > FREEWAY CONGESTION & RELIABILITY REPORT > Freeway Performance Measures Figure 1. 2016 Metro Region AM peak congestion severity northbound/eastbound Chapter 4 2016 Metro Region AM Peak Congestion Severity 4 Northbound/Eastbound ¦¨§75 ¦¨§94 59 53 ¦¨§696 ¦¨§96 10 14 ¦¨§96 39 ¦¨§275 2016 Congestion Severity Severe Moderate ¦¨§94 Low ¦¨§75 3 > FREEWAY CONGESTION & RELIABILITY REPORT > Freeway Performance Measures Figure 2. 2016 Metro Region PM peak congestion severity northbound/eastbound Chapter 4 2016 Metro Region PM Peak Congestion Severity 4 Northbound/Eastbound ¦¨§75 ¦¨§94 59 53 ¦¨§696 ¦¨§96 10 14 ¦¨§96 39 ¦¨§275 2016 Congestion Severity Severe Moderate ¦¨§94 Low ¦¨§75 4 > FREEWAY CONGESTION & RELIABILITY REPORT > Freeway Performance Measures Figure 3. 2016 Metro Region AM peak congestion severity southbound/westbound Chapter 4 2016 Metro Region AM Peak Congestion Severity 4 Southbound/Westbound ¦¨§75 ¦¨§94 59 53 ¦¨§696 ¦¨§96 10 14 ¦¨§96 39 ¦¨§275 2016 Congestion Severity Severe Moderate ¦¨§94 Low ¦¨§75 5 > FREEWAY CONGESTION & RELIABILITY REPORT > Freeway Performance Measures Figure 4.
