Hello everyone I’m Samuel Wilson and I’d like to tell you a little about bike lanes here in San Francisco. In my last talk I covered various violations that occur in bike lanes, and came to the conclusion that having bike lanes does in fact make cycling safer, but how can we put bike lanes in effectively and cheaply?
The biggest problem with our bike lanes is how long they take to make and how much they cost, which is why where they should be put is a hotly debated topic. As soon as I started my research I found out that bike lanes here in SF are actually fairly cheap to install, coming just shy of $450k for a mile of protected lane, compared to one mile of doyle drive that cost $571 million. (One traffic light costs the city about $280k so bike lanes are actually really cheap) But still, other cities are building them for less and building them faster, so if we have the resources how can we build them better?
In doing a little bit of research I came upon a few different studies taken by different departments of transportation across the nation, and found that protected bike lanes are the most expensive to build. Having to tear up part of the street, put in a barrier and then repave everything is extremely wasteful and inefficient construction. If you were to simply put in some basic kind of buffer like a fence or cones the cost of building the lane would drop $20,000. Creating protected bike lanes also brings up the problem of time, when roads have to be shut down it creates a major inconvenience for drivers and businesses, which is why it takes a lot of convincing for the city to actually go ahead with such intensive projects.
So in order to save all that time and money, how can we create bike lanes and protect them cheaply? Well in New York City because of the lack of room city engineers had to get creative, so they lined their bike lanes with potted plants and pieces of art to separate cars from the bikes. It took just 2 days to line most of the citys bike lanes, and accidents have since dropped 17%. And it was cheap too! Instead of creating a whole new area for bikes they simply turned their roads into a shared space, without changing the flow of traffic or ripping up the streets. So we’ve established that bike lanes don’t become that expensive or time consuming until you decide to completely separate them from the road, so how can we convince our city that it really is easy to create bike lanes at low cost?
We’re going to have to look at the different bike lanes throughout the city and their impacts both monetarily and on traffic. The bike coalition’s proudest accomplishments have been in golden gate park and market street. In Golden Gate Park the bike lane was moved behind parked cars in order to protect cyclists from traffic, but the project used almost $500k in paint alone and tens of millions of dollars to design and engineer over a 4 year period. Everything about the road had to be changed, lanes had to be moved, parking had to be moved and the road had to be widened and paved to create the bike lane. And of course since it cost so much and took so long the city wasn’t exactly happy to do it, although it now uses it to market tourism in the park. But switch over to market street, instead of widening the road and changing its layout city planners decided to paint bike lanes along the curb and protect them with plastic posts. Studies show its just as safe to have a curb between cyclists and cars as it is to have cones, yet one costs millions and one is relatively inexpensive. Either $450 thousand in paint and millions in construction and design or $450 thousand in paint and a couple thousand dollars for traffic cones? The answer is pretty simple, especially since safety is not affected. Cyclists are still separated from traffic, but in a simpler more efficient way that is of course cheaper.
Everyone can agree that bike lanes make the city a safer place, but it’s hard to build them when the city chooses the most expensive design. Yes there are replacement costs when cones get broken, but maintenance costs don’t even come close to being as expensive as ripping up the road to change its layout. The city already gets discounts on things like paint and and cones, so the price they would pay is much cheaper than what a normal citizen would pay. In order to make more bike lanes the city will have to think smarter not harder in order to become a more bike friendly place. It doesn’t matter if 10 or 50% of sfmtas budget is devoted to bikes if they use it for big expensive projects that ultimately hurt cyclists.
The bike lanes arent the problem, and neither is the budget. It all comes down to how and where the money is used to make cycling safer for everyone, thank you.

Hello, Riding is one of my best hobbies till now. I love to ride alone in night as it is a whole new vibe. Cross-country riding on my bike was at the top of my list and to fulfill my wish I had to arrange something for my online class because of which it was becoming nearly impossible for me to do cross-country riding. A friend of mine suggested to me about online class help service. Because of this service I am willing and able to go for a ride and fulfill my wish!!

Electric pruning shears are electric tools used for gardening operations to trim branches and leaves. It is mainly composed of batteries, blades, and the main body. When in use, the upper blade is driven by electric power to move back and forth, while the lower blade is fixed to complete the trimming work. The use of [electric pruning shears](https://hardell.com/collections/electric-pruning-shears) only requires pulling the trigger to complete the pruning of branches.
