Transtar measured the number of cars using a radar site at I-10/Katy Freeway and Voss, and compared to this time last year, the number of cars passing through this location in a 24-hour period is down approximately 50%.
Looking at single-day data, on March 25, 2019 there were 108,881 cars on the road in a 24-hour period. On March 25, 2020, there were only 39,022.
During the peak morning rush hours of 6 a.m. to 9 a.m., traffic volume dropped 39%, and in the heaviest evening rush hours of 4 p.m. to 7 p.m., it's down 47%.
Transtar also looked at speed data on our freeways. And no surprise, fewer cars mean faster speeds.
On I-45 North, measurements show the average inbound speeds at about 64 miles per hour, which was an increase of 121%. The inbound speed on the Gulf Freeway increased by 77% and on the Southwest Freeway, the increase was 105%.
