The CTA board today approved the purchase of 160 signs that will display Bus Tracker information at bus shelters across the city.

There will be at least one sign at each ward, the CTA said, and signs will be placed at downtown Metra stops to encourage riders to take the CTA.

The signs will display four lines of text with arrival information specific to the location of the bus shelter, the CTA said.

Bus Tracker began as a pilot project in 2006 and routes were added over three years. A feature that allows riders to get Bus Tracker information by text was introduced in 2009.

The funds for the signs were made available through a Regional Transportation Authority and federal grant, the CTA said.

Luminator Holding was awarded the one-year contract for more than $1 million for the initial purchase of signs. The CTA has the option to purchase up to 2,050 signs for up to five years.

JC Decaux, which owns many of the bus shelters around the city, was awarded a separate $687,300 contract to install, maintain and remove the signs.
