Note: 1. The traffic volumes reported for SR 167 and I-405 are 24 hour volumes in the managed lanes only. These are volume counts at a screen line and do not equal the number of tolled trips taken on the facility. I-405 operates as an Express Toll Lane from 5am – 7pm, Monday-Friday. SR 167 operates as a High Occupancy Toll lane from 5am – 7pm, 7 days a week. 2. HOT stands for High Occupancy Toll Lane; ETL stands for Express Toll Lane. 3. Baseline is defined as volume number from the same weekday of the same month from the baseline year*. For example, Wednesday, April 3, 2019 would serve as the baseline for comparing the volume data from Wednesday, April, 1, 2020. *Baseline year is defined as March 2019 to Feb 2020. 4. Tolling of the SR 99 tunnel began on November 9, 2019. The percentages in the chart above represent the difference between tolled 2020 traffic volumes and un-tolled 2019 traffic volumes. The dramatic increase shown for Thursday, July 2, 2020 is because the comparison day aligns with Thursday, July 4, 2019 and the holiday travel associated with that date. The increase shown for Wednesday, December 22, 2020 is because the comparison day aligns with Wednesday, December 24, 2019 and the holiday travel pattern associated with that date.
