(Crain's) — The Chicago Transit Authority plans to install LED signs at 160 bus shelters to display estimated arrival times.

The signs, which will be installed at busy transfer and connection points, aim to provide information similar to what's available on the agency's online Bus Tracker program.

A CTA spokeswoman could not say when all the signs would in installed.

The roughly $1.7-million cost of the project is funded through grants from the Regional Transit Authority and the Federal Transit Authority. More than $1 million will be spent on purchasing the signs, and the remainder will go to outdoor advertising firm J.C. Decaux to install and maintain the signs.

The concept was first tested in 2006, when the CTA installed a sign at Jefferson and Madison streets for the No. 20 bus.

The CTA has the option to buy 2,050 more signs from Plano, Texas-based Luminator Holding L.P. in the next five years.
