CTA

Last week's Streetblog Chicago post about Mayor Rahm Emanuel's O'Hare express train proposal struck a chord with readers, with dozens of retweets and almost 100 comments. Lots of people agreed that the existing CTA Blue Line run between the Loop and "the world's busiest airport" is already a relatively fast, high-quality service. Many readers also concurred that an airport express would be costly to build and expensive to ride, which makes the project a bad use of taxpayer money that could be better spent improving neighborhood transit.

Earlier this month, the CTA, Metra, and Pace announced that they are delaying the launch of the Ventra mobile app from this spring until this fall, and that an independent civic app testing group will help vet it. Contrary to what Chicago Tribune transportation writer Jon Hilkevitch wrote, that's not a sign that there are "undisclosed issues" with the technology. Rather, it shows that the transit agencies are being careful to thoroughly test the app before releasing it to the public. Given the rocky launch of the Ventra card two years ago, that's a wise strategy.

If you ride Chicago Transit Authority buses, you've probably had the infuriating experience of waiting an eternity at a stop, only to have two or more buses show up at the same time. This phenomenon, known as bus bunching, is the bane of most big-city transit systems in the U.S.

A new bill that passed the Illinois Senate last week would create a new class of tax increment financing district that could only be created around Chicago transit stations and lines to capture the property value that being near transit generates. Most of the revenue generated by these TIFs would be earmarked to pay for construction of rapid transit lines, stations, and other transit-related facilities.

There are several pros and cons of the city's controversial plan to sell the Pritzker Park site for development. One important and urgent aspect is that it would be an unparalleled – and potentially free – opportunity to create the first enclosed, wheelchair-accessible transfer between the CTA's Loop elevated lines and the Red and Blue Line subways.

Imagine this scenario: You're running late to catch Metra's UP-North Line to Rogers Park and, because the trains run so infrequently, you really need to make this run. You don't have a 10-ride ticket in your wallet, the line for a ticket agent is too long, there are no vending machines at Ogilvie Transportation Center, and the conductors will charge you a $3 surcharge (soon to be $5) if you buy a ticket from them.

Way back in 2012, one developer proposed what was then a radical idea: tearing down what had been a cheesy restaurant and a moat of parking overlooking a faded corner, and replacing them with a gleaming tower housing 99 apartments, two shops, and just 16 car parking spaces. Ever since 1611 W. Division Street showed the way -- both from a legal and a market standpoint, developers have flocked to the adjacent blocks of Wicker Park to try and replicate its success.

In its proposed budget for 2015, the Chicago Transit Authority didn't take much of a leap of faith when forecasting continued growth in the record crowds boarding its trains. However, CTA also optimistically forecasts that a multi-year slide in bus ridership, which accounts for 57.6 percent of the system's total ridership, will end -- and that instead bus ridership will "stabilize" with a 0.4 percent rebound.
