When the MBTA released a summary of the feedback it received on proposed fare increases, officials analyzed its 8,105 responses to determine how many were “negative’’ (73 percent).

But according to data behind that survey, which was released Friday, officials also failed to include some responses that are relevant as board members prepare to vote Monday on raising fares.

About 43 percent of pass holders who used an online comment form said they would stop using the MBTA if it raised fares 9.77 percent systemwide, according to an analysis by Steve Koczela, the president of MassINC Polling Group.

And about 29 percent of pass holders who responded said they would stop using the MBTA if it increased fares by 6.71 percent, according to the data.

Koczela noted that the MBTA released both the summary and the data behind it late on two Friday afternoons, a move that could be viewed by the media as an attempt to get less news coverage on a negative subject. He also was struck by the MBTA’s choice to leave out data on key questions, such as the number of riders who said they would stop using the system if fares go up.

In addition, the survey initially had asked riders to choose which fare increases they would prefer without giving riders an option to say they didn’t want any increases at all. (The MBTA later added that option to the survey after hundreds already answered).

A T official said they did not release the questions about people who would stop riding the MBTA because not all riders were asked.

“We didn’t report this data in the summary of comments because it was not asked of all riders and only makes sense in the relative context, so we would have had to report’’ on the numbers for every single pass the T offers, said Laurel Paget-Seekins, the T’s director of strategic initiatives.

Paget-Seekins also said the responses came from an online comment tool, so MBTA officials were not confident the results reflected most riders. She also said the impact of increased fares on ridership is typically much lower than the responses would suggest.

But it wouldn’t have hurt to present such data to the public.

“This is the opportunity for riders to provide feedback,’’ Koczela said. “The way the survey was conducted, presented, and released suggests rider feedback was not valued very highly.’’

New traffic signal system for buses will get hearing

A few weeks ago, I spent half of a column expounding on transit signal priority, which is basically technology that helps move buses along faster on city streets. For example, it includes traffic signals that turn green when they detect an approaching bus.

Many fans of the technology say Boston needs to catch up so the buses can become more reliable for those who use them.

Now, Boston City Council President Michelle Wu is calling for a City Council hearing on the subject.

“Public transportation is fundamental to so many of the issues that we’re advocating for on the council: access to good jobs, access to affordable housing, environmental sustainability,’’ she said.

In an order calling for the hearing, Wu wrote that the existing traffic control system prioritizes individual vehicles over mass transit, and Boston needs to work with the MBTA to “correct this imbalance.’’

The matter has been sent to the council committee on parks, recreation, and transportation, and a hearing will be scheduled within the next few weeks, she said.
