The CTA said this week it is delaying installation of more than 200 Bus Tracker displays at bus stops across the city so it can make upgrades to the signs.
The CTA had announced in September 2011 that 400 electronic displays at bus stops would be installed within a year. The CTA said the first 150 signs were implemented by the spring, and the agency is delaying implementing 210 signs as it makes changes to the system.
Installations now will not likely occur until 2013, the CTA said, and the total quantity installed will only be 360 displays partly because of additional costs for the technology changes.
When the CTA announced the project last year, the agency said it would test the first 150 signs before implementing the rest of the signs, spokesman Brian Steele said.
"We did test it and found we could make improvements," Steele said.
The agency also realized it did not need 400 signs to obtain its target of reaching 80 percent of bus riders, Steele said, so the total sign numbers were reduced by 40 signs.
Changes to the displays, which were approved Wednesday by the CTA board, include:
>> Relocating the wireless signal antenna to improve signal strength and sign reliability
>> Switching the communications modem to improve connectivity
>> Retrofitting and installing an audio button locator tone that can be set at different decibel levels
This is not the first time the CTA has backtracked on an ambitious plan to better its amenities. The CTA said last year it would clean 100 rail stations by September but as of earlier this month, cleaning crews had only been to 57 stations.
