Where do you get the idea I'm against public transit. I favor public transit and maximizing use of funding to serve the most riders. The GLX was court imposed and not a decision based on how money best serves riders across the system. Riders served already have bus transportation, so no service population increase. There is only a quality gain which will draw some more riders. Given maintenance backlog impacting quality and many other opportunities for service in the system, the GLX is a bad idea, much like turning Comm Ave into an Interstate, which I would strongly oppose.
I want the MBTA to get more funding, and contributions from local city and towns is an opportunity. The current formula is unfair and areas getting premium service should be paying premium prices. Somerville wants premium service with the GLX and should help pay for it. Cambridge gets premium service and doesn't pay for it - it needs to. The Green Line in Brookline is only marginally better than bus service due to suffering many of same delays motorists, including bus drivers, face.
Constricting major city streets more by turning travel lanes into bike lanes also impacts bus service, which is serving more people than the bike lanes. Thus its a bad idea too. On Mass Ave in Arlington, there are over 6,000 daily bus boardings for about 250 bus trips. Removal of an outbound travel lane (leaving one) to make a bike-only lane for 20-300 daily cyclists (depending on weather) who could have instead rode the T for at least much of their journey, using the T's bike racks.
Constricting major streets in the name of pedestrian accommodation in Boston has not shown increases in that mode or increased safety in exchange for the service decline to motorists including MBTA buses. The 1997 degradation of Mass Ave in Central Square has not improved safety. Its the state's #1 hot spot for bike accidents and #2 for pedestrian accidents. Enormous sidewalks did not seem to shift mode to walking, just favored bars and Starbucks over the retailers and Indian restaurants before. Former customers came far away (by car) to businesses. Loss of mobility and parking kept them away. Drinkers and loiters are more local and less inclined to drive. The poor got priced out of the area by huge price increases.
Bicyclists are the ones opposing the MBTA with bike lanes which degrade service and HubWay programs to compete, while also helping it with bike parking at stations and transporting their vehicles on the MBTA which add users. Making roads flow benefits both bus riders and private transportation, so challenges the MBTA on quality, where it loses when people have a choice. Reducing choice with bus only lanes and usury parking supply and costs is a loss of freedom and choice to make suffering on a T bus or bicycle look more appealing. Net quality of life and productivity suffer just to promote what people don't want by fascist planners who think much like communistic economic planners.
