Travel Time Reliability: On-Time Arrival
Travel times vary greatly from day to day, and travelers remember those few bad days they suffered through unexpected delays. Travel time reliability measures the extent of this unexpected delay. On-time arrival provides an estimate of how many times a traveler is anticipated to arrive at the destination on time. Areas with the heaviest congestion on Florida's freeways are susceptible to unreliable travel times.
In 2019, on-time arrival along the freeways decreased from 2018 by 1.4 percentage points for the urbanized areas of the seven largest MPOs during peak period. Heavily congested facilities are susceptible to unreliable travel times, and the 0.4% decrease in daily reliability for the seven largest MPOs corresponds to the increase of 1,226 hours in daily hours heavily congested.
