The CTA got a $1.6 million federal grant to "examine the
feasibility of Bus Rapid Transit service [along Western Avenue] as a means to provide faster service, improved connection points and enhanced transit services."
BRT on Western Avenue might actually make an impact. The "justification of need" is that "the corridor contains regional destinations, offers many redevelopment sites, has high bus ridership and is home to many zero-car households."
Here's a primer video on BRT done well - and first - in Curitiba, Brazil.
