Commuting with an Umbrella

It was raining today, quite heavily in fact. In an urban environment that provides very little consideration for folks using bicycles it is not a pleasant experience, especially if it is anything more than a light spring rain.
Mostly this is due to the road curving to the edges, where the bicycle lanes are. This is to help drain water off during especially heavy storms to make it safer for drivers. That is the key, drivers, for cyclists traveling along the curb water collects, pools and covers up the potholes that were already there. Combine this with poor roads that are barely ride-able when it is dry, cars speeding past and hopefully not splashing you, low visibility in general, and loss of braking/maneuverability, you have a very unpleasant environment.

What does riding with an umbrella have to do with it? Citizen cyclists (I believe Copenhagenize has popularized the term) should be able to ride safely while carrying an umbrella if they choose to do so.
This gets to the problem with most of the built infrastructure for bicycling in the USA. It is not designed so that it is if not pleasant, at least tolerable, to ride in the rain or any other weather condition, or any time when it is not 75 degrees in the middle of the day with little traffic and a bit of sun in May.

I might argue that even with the typical built infrastructure today, it is mainly presumed that folks using it will do something else when it rains, or are really out to enjoy the ride and not actually get anywhere safely and comfortably, or are too die-hard for rain and puddles to stop them.

All of that being said, with a little coordination and picking the right streets one can ride with an umbrella even in the crazy road environment of Cambridge/Allston. My route earlier today is below, with the parts I used my umbrella in blue and the rest in light red.

As you can see of my approximately 3.5 mile urban route I can use an umbrella safely about 60% of the time (around 2.2 miles) However that is just me, I am pretty comfortable and secure with my bicycle, I have good breaks and good control. For somebody who does not use a bike often, if they tried to bike with an umbrella there is only one section where they could. A .6mi section from Western Ave to the overpass of the highway. This is so little that it is not even worth it, unless you lived along here and were going to the bank or a friends house nearby.

The reason that would even be possible is that this is a traffic calmed road designed to be so narrow two cars can not pass each other but two bikes and a single car driving carefully can.

Yes this is actually two way! This design means very limited auto traffic and what traffic there is is usually driving very carefully and slowly and typically won't even pass a bike going in the same direction, although there is room to do so safely.

In general these issues are why we need to really look at how we are designing bicycle infrastructure. No we can't design around the best rain protection possible (covered elevated paths etc.) but we should start looking at how we build roads and side-paths that can allow folks on bikes, or wheelchairs, or on foot to better enjoy getting to where they need to go even when it is raining out, or snowing, or hot or cold.

More thoughts on weather cycling and what other countries are doing (notably not the US) some point soon.

From EcoVelo: A Video, and a discussion from me

This was posted up on Ecovelo today, and I thought it worth a mention:



Once you have watched it, and/or taken a look at the comments on the Ecovelo post on this video come on back, I do want to think some more on what this brings up, in terms of design.

Now I am a huge proponent of separated infrastructure when speeds are higher than 15/20mph. For the Dutch, this typically means no separation in residential areas, and perhaps in city centers as well (although these are typically ped/bike only with deliveries at odd hours). This has provided for a huge cycling rate, the highest(overall) rate in the world(something over 30% I think now, some cities top out over 50 if there is a college). They are the only ones that have achieved this rate through effort(China/India have high rates through poverty and need, typically) and thus they are a good model to use if we wish to see cycling as a significant transportation mode-share.

This poses interesting challenges in terms of our cities here in the US. The population of the entire Dutch country (~16 million) is less than that of New York City(~19 million) for example. It is hard to find space to allocate to the majority of road users in NYC(ped/bicycle) without stepping on somebody's toes, and the car/taxi lobby is quite loud when it comes to stepping on toes.

So what can we do?

In many cases the ability to have a good separated lane is critical, we need it, to encourage new bicycle users to come to the street, and to narrow the space for cars (thus reducing traffic and through speeds) this is good, and for the most part we can do that in blocks, yes there are pedestrians and yes there are loading issues, still a problem, but I feel that that kind of problem can be solved by working with delivery times and positions, and making sure pedestrians know that there is a bicycle route next to the sidewalk, and it is not for them to go into(that should become apparent as more cyclists use it every day, people wouldn't have a chance to step in it for fear of being run over every 5 seconds).

Providing ample space to pedestrians so they do not use the bicycle lane as extra sidewalk is also critical to this design. Yes this means less road space, but often lanes can be re-stripped down to the minimum MUTCD standards and a couple feet for either side can be added to the curb(or get rid of parking along one side, or remove a travel lane, or make it one way...). The main point being, the designers we have now can figure out how to squeeze an ok separate lane into the built environment, its not perfect, but it can be done and it can be done safely in many places.

The big deal is at intersections(and noted in the video). For the Dutch, many intersections are round-a-bouts with wide spaces around them to provide for proper building of separated facilities.(example ped/bike/car, example bike/car, example bike bypass Either that or they are very small and it is in a shared use space, thus no need for separation in the first place. (example)

The crossings are not right at the entrance/exit to the roundabout, but typically at least 1 car length back from where one would enter the actual round-a-bout (typically 2 car lengths with newer designs). This means you interact with ped/cyclists at the start or at the end, not at the same time as other cars, as you travel through the round-a-bout, you as a user of the space can focus on one element at a time, not everything at once (as in a typical urban intersection).

Intersections are a different story. If you have spent times zooming around the Netherlands via the wonders of Google, you will notice that no intersection is exactly the same as the other, each is fit into the specific environment of that situation, or designed to meet the perceived development opportunities for each site (in fact you don't typically find many major road intersections). This is a note for any type of interaction between multiple transportation options (ped, bike, bus, car, tram etc)

For a typical 4 way intersection there are a couple options, depending on traffic and size of road/speed. Really we are just interested in city/urban intersections. In Assen, these are actually few and far between, other than the low speed shared road intersections. Here is one Example though. Pedestrians are combined with cyclists, but have their own area crossing the intersection and have their own lights. Any disable persons can use the bicycle crossing, or the ped crossing, as curb cuts are provided. Walk buttons are provided on all 4 signals to cross this one part of the intersection, there is a resting area in the middle, in case you move slower than the full crossing lights(as a ped). Typically ped and bicycle lights for the whole intersection would go at once, and no turns would be allowed onto this road while bicycles and peds are moving. Either lights are timed at different speeds, a ped pressing the bicycle light will find they might be stuck halfway across.

This intersection appears to not have a loop detector for bicycles, but does have a button, and these do respond to cyclists and often one push will shortly stop all other traffic and allow the cyclist to cross. In many cases intersections have both(loop and button).

In some cases a loop detector is placed further back from the intersection so that a cyclist, moving at typical 10mph will reach the intersection as their bicycle light turns green. Other places it is always green for bicycles unless a car comes and triggers the car detector loop, in which case the bicycle light will turn back to green shortly. Yet other places the bicycle lights are triggered to give cyclists a "green wave" to allow for ease of movement and convenience at 10mph(or designated speed). Left or right turns on red are only allowed in special circumstances, and sometimes these turning options have their own separate interaction with cyclists(even at a round-a-bout)

If the road has many driveways or entrances or has deliveries, and there is no room for a separate infrastructure, what the Dutch have done is lower the speed, or remove through traffic alltogether. (Example area)

Here there is a road on the left that has parking and a "door zone" cycle lane with two traffic lanes (what we typically see here in the US). This is a lower speed road, maybe 25/30kph max, and the bicycle lane is dashed to allow for cyclists to move as safety dictates.

The road to the right (which google has gone down, but technically really should not have unless it was during delivery times...) is a bicycles only in the center, and pedestrians to the side (although at low speeds for bicycles it is not critical to separate (example) (again this must have been done on a Saturday/Sunday morning, due to lack of ped/bike traffic and amount of truck/delivery traffic when viewed at streetview)

Even when looking at more of a grid pattern, such as in Groningen to the North, many streets are ped/bike only and limited car traffic, very low speed shared space, or even along a main higher car traffic/bus route road, the intersecting roads are one of the above types, with "give way" markings along the road as designation. (Example)

Yes grids are wonderful, but we need to do more than just build a European style cycle track along the uninterrupted roads, or build it and do nothing about side streets. The Dutch have shown that intersections are terribly important, and the most important to get right. Many deaths/injuries in NYC are at intersections, such that it is safer to jaywalk mid-block than cross at the intersection (in terms of likelihood of injury) to make a point.

What we need to do is start making side streets bike/ped only, or limit car/truck access to only deliveries, or certain hours, or make one way(with bi-directional cycle paths). We need to close off streets and narrow others. By moving the traffic from these side streets to designated larger arterial roads, we have more options in terms of planning and redesigning the intersection, there is simply more room to do it right. Space is always a problem, and will be when retrofitting a city, but it is true, if there is a will, there is a way. Yes the US is uniquely different from Europe, but many things they have done can be adapted here and made to work just as well. All it takes is knowledge/understanding of the issues, creative thought, and a will.

Much of the Netherlands was as we are today in the late 60's, it took concentrated and sustained effort to be where they are now, many lessons were learnt and designs improved. We have the chance to use some of the best and well tested designs out there, if we simply open our eyes.

We can make American more bicycle friendly, even a city the size of NYC, or car choked as LA.

Yes there will be issues with urban hipsters speeding along on fixed gears, grandmas on old cruisers, business men in Lycra commuting to the office, small children or families going to the park etc.

The more types of people we have using a bicycle, the more everybody starts to play along. Yes there are bad apples, they are part of our society, but if the majority is going at 12mph, and a few want to go at 25, and simply cant because there are too many bicycles on the road, well then maybe that is a sacrifice we have to make to allow for more people to choose bicycling as a transportation option

From Streetsblog: The Persistence of Bike Salmon

Streetsblog.net The Persistence of Bike Salmon

This is a old post from about a month and a half ago, but got me started on my sidewalk cyclist post, as well as mention the sidewalk salmon in a "bikes seen today" post.

It is something that I have thought and read a great deal on, why do we have "wrong way" cyclists.

I have read in a couple places some thoughts that make sense, many are from David Hembrow, many are from Streetsblog and many others are from the depths of cyber space.

In this country the age when you ride your bike dictates the rules you must follow. It starts out with the training wheels on the sidewalk, and then it progresses to regular low speed (although some kids go pretty fast!) cycling on the sidewalk. At a certain age it moves to cycling against traffic, especially in neighborhoods that have no sidewalks. The example is they are acting like pedestrians and feel that this is the safer method, so the cyclist can make sure the car has seen them. I understand why this is encouraged, especially with kids; bikes in the US do not have mirrors included with them. And many are bought at big box stores that do not sell these accessories, and parents who are not clear on the rules themselves, feel that this is safe (or safest) for their child. Finally you must ride in the same direction as cars once an adult, and must act like a car in all you do.

For many people that are starting to enjoy riding again, they last rode a bike when they were a kid, they might be from a generation where 16 meant a car and freedom; the bike was quickly forgotten. When somebody who has not ridden a bike in many years, picks one up today, they revert back (typically) to the last time the rode and the rules that were in effect then, as well as how safe they felt riding a certain way. This typically means riding either on the sidewalk or against traffic, or both.

This is the problem.

In the Netherlands, children do not have training wheels, they learn to balance on scooter type things with two wheels a seat and no pedals, once they learn how to balance which can be achieved in one day with enough dedication, they graduate to regular bikes, sized for them.

As David Hembrow has shown, children's bikes have racks, fenders, lights and breaks just like their parent's bikes. They also have the safe separated infrastructure to ride on and are taught in school to ride like a cyclist. They are not told how to ride like a car or ride like a pedestrian, they are a bicyclist and are neither of the above. So even if they turn 16 and forget the bike for a while with a new car, when they choose to go back, they ride the exact same way they learned as a child, which is safe, efficient, and easy.

It is because of the infrastructure though; we have either sidewalks or roadways here in the US. Cyclists get nothing (really in the vast majority of communities). We have to choose to ride like a car, or like a pedestrian. It feels safer to be a pedestrian on the sidewalk and so many people ride there. David has talked in depth about the ideas of subjective safety; his posts on the topic are worth a read.

However some studies have shown that even with limited on road bike lanes and what would be considered the least effective (and sometimes dangerous) cycling infrastructure in The Netherlands, that rates of wrong way cycling as well as sidewalk cycling are reduced by over 50%.

Bike salmon are a consequence of infrastructure that does not serve a cyclist and only serves pedestrians (not always bad thing) or cars. This is the case with sidewalk riding as well.

I am a firm believer that if you provide true separated infrastructure, away from fast moving traffic on roads over 25mph, roads faster than 40mph create more of a separation and provide under or overpasses at busy junctions, make zones that are 20mph or less have bicycle priority, provide for safe interactions at intersections via roundabouts or bike only lights, and make safe secure staple racks available at any destination and place of business, that the US can achieve the 30%+ bicycle mode share that many cities in Europe, and especially Denmark and The Netherlands have achieved by providing for their cyclists.

Bike salmon will be an endangered or extinct species, if we manage to achieve the goal of true equality on our streets.

We know what needs to happen; doing anything less is tantamount to lip service, and pandering, and in many cases can be more dangerous than nothing at all. It is never too late to start doing it right.

For further reading I encourage a look back through the wayback machine over at David's blog, its a treasure trove for anybody that wants to see how it could be done right.

some thoughts and a project

So one of the disadvantages about being home is that yes I have more free time, but I also have dialup internet, which means I don’t get to keep up to date on topics nor have an easy time working with pictures, video or other things for the blog. That is changing soon as my family moves into the 21st century with a DSL connection that should be up and running in about a week. I wanted to mention one of the projects I am currently working on though in this brief post.

Jessica, who I mentioned 2 posts earlier, contacted the group about a innovative car-share scheme she is working on in Brattleboro, and I offered to look at some GIS data and provide information on density and income levels and age groups in the area around Brattleboro city center. The Vermont GIS database is a bit trickier to work with then the NY database, but I found the data ok. The main problem I am running into though is in the information table (like an excel sheet) attached to each file there is a whole lot of data, but the acronyms are near impossible to figure out. Its very frustrating and I have hit a brick wall due to that, I need to contact somebody in the Vermont GIS office to see if they can help a bit.

I was musing about a light rail commuter line connecting some of the local towns to the major employers in the region yesterday, I might put together a little post on the thought in a day or so. There is lots of promise here for sure, but its never going to happen until people are forced to

In the meantime I wish you and yours a happy holiday, Merry Christmas, Kwanzaa, Hanukkah, festivus, whatever you celebrate.

Be well, be safe, and best wishes
John
