Confusing turnstile delays that sometimes led to denied entry or a second charge from double-tapping have largely vanished.
Ventra riders also reportedly are processing transactions faster.
"In its second weekly Ventra progress report, the CTA released data showing that its rail system processed 99.8 percent of more than 5 million transactions under 2.5 seconds, with an average speed of 0.6 seconds. This is for the period Nov. 18 to Dec. 1, following software upgrades that have been made to the rail system," a CTA news release said.
The release also indicated Ventra call center performance improved. Average call wait times are under five minutes. Overall call volume declined 17 percent in November from October, the release indicated.
