Downtown Boston “signals walk” with Boston Transportation Department

Downtown Boston “signals walk” with Boston Transportation Department

WalkBoston took a downtown Boston “signals walk” with Boston Chief of Streets Chris Osgood, Acting Transportation Commissioner Greg Rooney and Boston Transportation Department Chief Planner Vineet Gupta on August 1st. We looked at several pedestrian-filled downtown Boston intersections and discussed the many ways in which Boston’s traffic signals are not yet fulfilling the policies outlined in GoBoston 2030 such as: making “walk-signals intuitive and giving people walking a head start,” or “shortening wait times at crossings and make signals adapt in real time to pedestrian behavior and flows.” (Check out page 140 for Pedestrian-First Traffic Signals.)

At 9 AM, during heavy commuting hours for walkers and T riders, the crosswalk across Cambridge Street in front of the Government Center T Station required pedestrians to wait 90 seconds to get a WALK signal. We also looked at several intersections where STOP signs would provide better service for both walkers and drivers – such as at Milk Street/Washington Street in front of the Old South Meeting House.

As we have for many years, WalkBoston will continue urging the Boston Transportation Department to fulfill the City’s motto of being “America’s Walking City” by making traffic signals in Boston work better for walkers.

RE: WalkBoston comments on traffic calming in Somerville

To the Somerville City Council,

My name is Adi Nochur and I am testifying before you as an East Somerville resident and a member of Somerville’s Vision Zero Task Force. I am also commenting as a Project Manager at WalkBoston, a statewide pedestrian advocacy organization. WalkBoston is a signatory to the traffic calming petition that spurred today’s Council hearing.

I want to briefly comment on three issues, as follows:

  1. Speed Limits: WalkBoston supports efforts to reduce speed limits on residential streets in Somerville to 20 miles per hour. Achieving this goal is a fundamental issue of roadway design. WalkBoston also supports state legislative efforts to align speed limits on MassDOT and DCR roadways with local speed limits (H.3092/S.2042). As an illustrative example, we know high traffic speeds are an ongoing concern on Route 16/Alewife Brook Parkway.
  2. Equitable Enforcement: Data gathering is critical to ensure equity in traffic enforcement. Concerns over racial profiling are front and center in the current state legislative debate over hands-free/distracted driving legislation and local enforcement efforts also need to demonstrate sensitivity to these issues. State legislation that would enable automated enforcement (S.1376) can be part of a potential solution here.
  3. Concurrent Signalization: WalkBoston supports concurrent pedestrian signalization with a leading pedestrian interval at most signalized intersections. Our stance on this issue is further detailed in a letter we submitted to Mayor Curtatone on March 29, which is included as an attachment to these comments.

Thank you for your consideration of these issues. WalkBoston looks forward to continuing to work with the City Council to help Somerville achieve its Vision Zero goals.

Sincerely,
Adi Nochur
Project Manager

Dear Mayor Curtatone,

We wanted to reach out to you regarding recent signal changes on Beacon Street where exclusively phased pedestrian signals have been converted to concurrent phasing.

We appreciate that both City staff and residents are concerned about pedestrian safety and are pressing for more protections for people on foot. You said it yourself in the Somerville Times in 2015: “When you plan for people, you get walkable neighborhoods that create vibrant communities, with faces you recognize of people walking, pushing strollers and biking.”

LivableStreets and WalkBoston have advocated for years to move to concurrent phasing with leading pedestrian intervals (LPI). We ask that you please support the continued implementation of an overall policy of concurrent with LPI pedestrian signal phasing in Somerville, with limited exceptions applied in locations with (1) high volumes of seniors or children, (2) very high turning movements (250+/hour), or locations where data show a special need for exclusive signals.

We recommend:

  • The Leading Pedestrian Interval (LPI) be lengthened to give pedestrians a longer head start.
  • No Turns on Red signs be installed to restrict motor vehicles from turning during the LPI.
  • The concurrent walk signal phases should be automatic and not require a button. This is one of the key benefits of a concurrent signal. The shorter wait times for pedestrians are also shown to reduce the number of pedestrians who cross the street against the light.

At the intersection of Beacon Street & Park Street, 100% of vehicles coming from Park are turning. The City should consider whether an exclusive WALK signal is needed for pedestrians to cross Beacon Street or whether the volumes are low enough that a concurrent signal for the Park Street green phase (for pedestrians crossing Beacon) would be appropriate. There could still be a concurrent phase during the Beacon Street green (for pedestrians crossing Park Street or Scott Street) depending on the turning volumes.

At the intersection of Beacon Street & Washington Street, you might look at the signal timing adopted this week in Central Square, Cambridge. A right red arrow is now displayed during an extended LPI  (a “Super LPI”) which eventually turns to a flashing yellow arrow to remind drivers that they must yield to pedestrians and do not have an exclusive turn.

The reasons for, and benefits of, concurrent phasing and LPI are well presented in the brief by the City of Cambridge which implements LPI/concurrent phasing at almost every signalized intersection. There is also some fairly well documented research on LPI safety that is shared by the National Association of City Transportation Officials (NACTO). Jeff Speck in his recent book Walkable City Rules says, “Keep signals simple: most intersections should be concurrent and quick.” (Rule 74, page 176).

It should be noted that while concurrent phasing with LPI is generally safer and more convenient for people walking than exclusive phasing, there are exceptions. Older residents, people with mobility challenges, and small children in particular may feel more at risk. In most cases, when exclusive phasing is used, it is often near schools or senior centers, or locations with high volumes of turning cars (such as Inman Street at Mass Ave in Cambridge).

With the ongoing construction detours around Union Square there is presently the potential for increased vehicle volumes through these intersections and Somerville could consider combining concurrent and exclusive phasing to get the benefits of both for the duration of the detours.

Another option that could be tried is a push-button activated exclusive phase (noted by signage) that could serve the needs of people who feel uncomfortable crossing during a concurrent phase. Automatic concurrent phases would be retained during the balance of the time.

Dennison Crossing Walk Audit – Framingham, MA

Dennison Crossing Walk Audit – Framingham, MA

On Thursday, September 13, 2018, WalkBoston conducted a walk audit at Dennison Crossing in Framingham as part of the Executive Office of Public Safety and Security’s (EOPSS) Pedestrian Safety Planning Initiative for High-Fatality Communities. The EOPSS Pedestrian Safety Planning Initiative builds municipal staff understanding and awareness of the components of a safe walking environment. WalkBoston is working in partnership with EOPSS to address walking safety concerns in Massachusetts communities with high pedestrian crash rates, with the goal of reducing pedestrian fatalities and serious injuries in the Commonwealth. According to data provided to WalkBoston by EOPSS, Framingham has seen 3 pedestrian fatalities and 128 serious pedestrian injury crashes between 2012 – 2017.

Support for “Super LPI” in Central Square, Cambridge

Support for “Super LPI” in Central Square, Cambridge

March 26, 2018

To:
Cambridge City Council,
Cambridge City Clerk,
Joe Barr – Director Cambridge Traffic, Parking & Transportation (TPT)

From:
Wendy Landman, Executive Director, WalkBoston

WalkBoston believes that TPT’s suggested change for the Central Square Pedestrian Signals will provide improved pedestrian safety. As described in the March 21 Memorandum from Joseph Barr, the Super LPI will provide an effective way of managing this high volume intersection.

WalkBoston agrees with TPT’s analysis of the situation and with the conclusion that a concurrent signal phasing with a longer LPI is the best overall solution. We concur with the finding that an ALL WALK signal phase would not be appropriate for Central Square and would lead to lower levels of service for pedestrians, and confusion among both pedestrians and drivers.

WalkBoston also appreciates TPT’s plan to review operations after the Super LPI is installed.

Thank you for the opportunity to comment on this signal revision.
