ThisPOSTED is to SP takeEED out the delay caused Delay No Delay Delay by the lower average speeds from commercial vehicles.Recurring POSTED SPEED 60 MPH Recurring Total delay per mile > Delay per mile is calculated by taking the total60 delay MPH and dividing it by the length of the freeway. This was performed for each route in each county. AVERAGE SPEED Non-recurring Non-recurring/recurring delay > Non-recurring delay is calculated ACTUALby taking SPEED the difference between the actual speed (any time the speed falls below 60 mph) andACTUAL the average SPEED speed. Recurring is measured by taking the difference of the total delay and non-recurring delay.

Weighted4.0 Congestion > Number of congestion hours multiplied by the segment length. Congestion along longer segments will get more consideration than congestion along shorter segments. 2.0 Reliable Unreliable 0.0 * On segments with a speed limit of 55 mph, delay is calculated when speeds fall below 55 mph. 1:00 PM 2:00 PM 3:00 PM 4:00 PM 4:00 5:00 PM 6:00 PM 7:00 PM 8:00 PM 9:00 PM 1:00 AM 2:00 AM 3:00 AM 4:00 AM AM 5:00 6:00 AM 7:00 AM 8:00 AM 9:00 AM 12:00 PM 10:00 PM 11:00 PM 12:00 AM 10:00 AM 11:00 AM Time of Day 4 Delay No Delay Delay POSTED SPEED 60 MPH ACTUAL SPEED > CONGESTION & MOBILITY REPORT > Freeway Performance Measures POSTED SPEED Recurring Chapter 3 60 MPH Recurring AVERAGE SPEED Non-recurring Performance MeasuresACTUAL Definitions SPEED Northbound Travel Times Avg 75th % 95th % 16.0 14.0 12.0 Small dierence Large dierence between average between average 10.0 and 95th percentile and 95th percentile travel times travel times 8.0 Minutes 6.0 4.0 2.0 Reliable Unreliable 0.0 1:00 PM 2:00 PM 3:00 PM 4:00 PM 4:00 5:00 PM 6:00 PM 7:00 PM 8:00 PM 9:00 PM 1:00 AM 2:00 AM 3:00 AM 4:00 AM AM 5:00 6:00 AM 7:00 AM 8:00 AM 9:00 AM 12:00 PM 10:00 PM 11:00 PM 12:00 AM 10:00 AM 11:00 AM Time of Day Travel Time Reliability > A measure of travel time consistency over a period of time. When travel times are unreliable, customers are more likely to experience unexpected delays. Travel 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. 5 > CONGESTION & MOBILITY REPORT > Freeway Performance Measures Figure 1. 2014 Grand Region user delay cost per mile Chapter 3 2014 Grand Region User Delay Cost per Mile 4 ®2131 ®231 ¦¨§96 ¦¨§196 6 2014 UDC per Mile < $75,000 $75,000 - $150,000 > $150,000 6 > CONGESTION & MOBILITY REPORT > Freeway Performance Measures Figure 2. 2014 Grand Region congestion hours northbound/eastbound Chapter 3 2014 Grand Region Congestion Hours Northbound/Eastbound 4 ®2131 ®231 ¦¨§96 ¦¨§196 6 2014 Congestion Hours < 50 50 - 100 > 100 7 > CONGESTION & MOBILITY REPORT > Freeway Performance Measures Figure 3. 2014 Grand Region congestion hours southbound/westbound Chapter 3 2014 Grand Region Congestion Hours Southbound/Westbound 4 ®2131 ®231 ¦¨§96 ¦¨§196 6 2014 Congestion Hours < 50 50 - 100 > 100 8 > CONGESTION & MOBILITY REPORT > Freeway Performance Measures Figure 4.
