In figuring out how 2 miles of reconstructed Massachusetts Avenue will work block by block with new separated bike lanes, members of a Cambridge working group said Thursday that they had to balance the conflicting needs of different kinds ofย transportation. They also had a challenge at least as big: community outreach.
Necessary trade-offs need to be signaled from the beginning to avoid the rancor that has surrounded bike lane installations so far, members said.
โItโs not that weโre trying to destroy businesses, or make it easy for people to do something over another thing, or that itโs all about the cyclists,โ said Laurie Pessah, one of 14 members of the working group appointed April 24 by the city manager to grapple with $50 million worth of road reconstruction between Cambridge Common and the Arlington town line. โBut itโs driven in large part by safety. And that that means slowing down traffic wherever possible, making it more difficult to do maneuvers that introduce conflicts that are hazardous.โ
People along the avenue need to hear the working group and staff โemphasizing safety as often as we can,โ Pessah said. โThereโs going to be delay, thereโs going to be inconvenience. But if those are in the cause of safety, I think weโll get further with the public and maybe be able to unite people to some extent.โ
Outreach must begin immediately with โwhatever information we have,โ said member and Harvard Square Business Association president Denise Jillson. โIf I have to go personally door to door to every single HSBA member from The Hong Kong restaurant down to the Porter Square Hotel, I am happy to do that. Because I want to make sure that people understand whatโs coming and how theyโre going to be impacted.โ
That may be essential. โI still meet business owners every day who donโt know about it,โ said Steven Beaucher, an architect and the proprietor of the WardMaps store on Massachusetts Avenue, referring to the roadwork.
Fighting for road space
The project encompasses improvements that go far beyond bike lanes, but city staff know from experience โ installing the lanes across Cambridge as part of the 2019 Cycling Safety Ordinance โ that they draw the most attention and upset. Adding them on narrow streets can mean having to remove parking spaces.
Pedestrians, bikers, bus riders and drivers are all fighting for road space, working group members said. Since the previous meeting May 18 โ the first time the working group met โ members were asked to visit the relevant portion of Massachusetts Avenue and identify areas for improvement.
Observations were wide-ranging. Resident Gary Dmytryk, for example, noted a pinch point at Walden Street where a bike lane cuts off, which โabsolutely has to be addressed, because itโs crazy to just have the bike lane disappear like that.โ Pessah, meanwhile, noted that in certain intersections, a high volume of pedestrians in combination with a large number of cars waiting to turn right results in backed-up traffic. Several working group members noted the difficulty of designating appropriate spaces for loading and delivery vehicles, including president of the Porter Square Neighbors Association Ruth Ryals, who โwas most concerned about commercial delivery, because they are everywhere, pulling over wherever they feel like it: in the middle of the car traveling lane or in the middle of the bike lane.โ
Guided by statistics and data
Incorporating every suggestion, however, will not be easy. Jerry Friedman, the supervising engineer at the Department of Public Works, emphasized the necessity of compromise. He identified two categories based on levels of necessity: fixed elements, referring to at least one lane of cars and a bike lane in each direction; and optional elements, including turn lanes, bus lanes, curbside access and pedestrian crossings.
โThereโs an intimate relationship between bus lanes and where we can and cannot provide curbside access, and median refuges. So thereโs work for us to do: to identify trade-offs through our analyses and make sure you understand the trade-offs,โ Friedman said.
To decide, the working group will be guided by statistics and data on such things as collisions, travel times and traffic patterns in intersection. The road design will most accurately match how people use the road, staff said.
Crosswalks and turn lanes
For example, intersections have two possibilities for crosswalk signals: concurrent phasing, in which pedestrians cross parallel to moving cars, and exclusive phasing, in which all pedestrians cross at once. Concurrent phasing has lower wait times for pedestrians and drivers, while exclusive phasing reduces the risk of collision between pedestrians and turning cars. To choose the bestย phasing, it can be good to compare the number of cars turning or going straight and the number of pedestrians in each direction โ though, as Cambridgeโs Street Design Project Manager Andreas Wolfe warns, โthereโs no golden thresholdโ between types of phasing.
Data can also show how to improve safety by making road use more intuitive, Wolfe said. Instead of โencouraging behaviors we know are unsafe,โ Wolfe said, the safest option can also be the most convenient option.
For example, effectively placed turn lanes can reduce the pressure drivers feel to enter an intersection, which increases the risk of a collision.
โWhen youโre trying to manage crossing two lanes of traffic coming at you, bicyclists coming in the other direction and pedestrians who are all the way on the other side of the street, thatโs sensory overload. Itโs really difficult for anyone to safely cognitively process all that at once. Thatโs where turn lanes come into play: making that safer,โ Wolfe said.
Instead of having a through lane of cars waiting impatiently behind them, drivers preparing to make a turn are diverted into a separate lane where they can more clearly account for pedestrians and bikers around them.
Such solutions are rarely universally applicable, and turn lanes have drawbacks too. If a turn lane is not long enough to accommodate all drivers trying to turn, Wolfe said, drivers trying to use it may begin to block the through lane. Then โsomeone whoโs trying to go straight may see a green light ahead of them but be stuck behind people who are turning. That encourages them to do something unsafeโ such as cross over into the opposite-direction lane while maneuvering around the cars in front of them.
Consistency and trade-offs
Another major difficulty working group members foresaw was in their approach: How to balance selecting a solution ideal for each block or intersection but keep the avenue as a whole consistent?
While piecing together an understanding of the issues, working group members started with a piecemeal approach. Wolfe and Friedman directed their attention to various intersections to illustrate specific problems and their potential solutions. Timothy Keefe, among others, highlighted the benefits of this โblock by block, section by sectionโ approach to accounting for the needs of different businesses.
Many members agreed, however, that inconsistent signage or other design elements tended to cause confusion. In particular, the availability of parking in off-peak bus lanes was a point of concern. The working group stated an intention to establish clear communication with Cambridge residents on intended road use.
They also discussed the necessity of community outreach and input throughout the process, hoping to clarify the necessary trade-offs from the beginning rather than waiting to present a finished product.
The working group will meet in July for a more detailed technical presentation and are discussing a walk of the avenue




“Necessary trade-offs need to be signaled from the beginning to avoid the rancor that has surrounded bike lane installations so far, members said.”
Nice idea, but it won’t work. The people yelling and complaining aren’t doing so because of a lack of communication, they just oppose bike lanes or taking anything away from cars. There has been no shortage of communication, every project has had 3 or more public meetings, city council time, flyers posted, emails sent, postings on the city website, etc. On top of that the CSO had years of debate and planning. Nobody has been surprised by these changes, that’s just a talking point they use against the changes.
@multimodal Agreed. People will oppose any change that even hints at inconveniencing drivers. The opposition to changing our streets is a mixture of self-interest and fear of change.
Letโs all of us think of something everybody would agree about to spend $50 MILLION dollars on!
I’m glad theyre trying to outreach more. Many of the bike lanes and changes (besides canning RTOR) have been good, but signage and communication is clearly terrible if so many stakeholders have been blindsided by it.
Anytime city hall uses the excuse they need money to provide housing for low income residents or fix the streets they need to remi they let developers, Harvard, and biotech to make billions for operating in Cambridge. If city hall wasn’t full of cowards who were owned by these evil corporations they’d have no problem taking money from these organizations to make Cambridge affordable for everyone. Instead they like to claim they are progressive all while causing middle to low income people to have to leave the city. Cambridge is only affordable for the rich and privileged thanks to city hall.
Outreach isn’t the issue. The businesses are going to complain about anything that even removes one parking space. The drivers are going to complain about anything that constricts the road. It’s not about a lack of understanding, it’s the inability to look past their own selfish needs to what’s needed for the greater good. Just get on with it and build what’s necessary so we can move on.
@VampireHunterD
It is going to get much worse in the next five years. More and more middle and low income people will be forced out of the city as taxes on residential property go up substantially, while taxes on commercial real estate flatten out, or most likely go down substantially. The Councillors are unwilling to face the facts, don’t care about finances (as one current councillor told me), or are not very smart when it comes to looking at the city’s finances.
This city is looking in the rear view mirror and thinks CRE growth and values are going to continue forever. At the same time it is recklessly spending money on non-crucial items and is underfunding its post retirement pension and health plans. You would think McGovern, Zondervan and Nolan would spend a bit of time looking at the financial situation. But, not to be. Let’s continue to spend $40,000 per mural for the “community trail.” Why not; the city has so, so, so much money.
The financial day of reckoning is coming and the city just twiddles its thumbs. The lower and middle income families are going to continue to disappear from Cambridge.
Most bikers do NOT follow the rules of the road, they need to have licenses! Many ride on sidewalks, wrong side of road, and do not stop for red lights esp. where people have the walk sign they speed by with no concern for people walking.
Inman sq is worse than ever, its more of a mess than before….be careful what you wish for.
@shedrovemehere Outreach is indeed the issue. Concerning the residents and businesses who brought up lawsuits against the city, if you take a chance to understand where they’re coming from, and why they felt the need for litigation, you would notice they’re not directly opposed to the bike lanes. Even now, if you take a nonjudgemental look at the CSFA website, you will see that nuance. Yes, it is not their main point, but it is there.
Many of the litigants and some of the prominent businesses are in Porter Square, so they know the area better than the bicyclists passing by. I myself am a Porter Square resident, and I support the $50M plan to redesign the Porter Square Mass ave and bike lane segment, also shared by City Manager Huang.
If only the pro-lane advocates allowed us Porter residents a constructive opportunity to share this insight without immediate, emotional rebuke and boycott of our businesses.
Maybe if we all came together from the start, and allowed each other to do so, we could have saved millions of our tax dollars by getting the bike lanes right the first time.
