Bikes vs. Cars

We know who wins the battle – physically and generally as a matter of policy throughout the U.S.

I hesitate wading into this as it is not normally my area of expertise. Caveat: my professional focus is public transportation. And yet, I feel the need to weigh in because there has been some very good writing done recently on bike laws and infrastructure and I have my own recent personal and professional experience to bear.

I’ll start off by saying that I am an occasional bike rider who commutes mostly to work, to pick up the kids from school and other local trips. I also live in Chicago – a city known for its traffic as well as its aggressive expansion of bike infrastructure recently.

My neighborhood, Jefferson Park, has been in the middle of a fairly dramatic fight over a complete streets proposal for Milwaukee Avenue, one of the major road arteries through Chicago’s northwest side. Ostensibly, the proposal follows the City of Chicago’s Complete Streets guidelines which state clearly that:

The safety and convenience of all users of the transportation system including pedestrians, bicyclists, transit users, freight, and motor vehicle drivers shall be accommodated and balanced in all types of transportation and development projects and through all phases of a project so that even the most vulnerable – children, elderly, and persons with disabilities – can travel safely within the public right-of-way.

To adhere to this policy a pedestrian-first modal hierarchy of road users has been developed in which “all transportation projects and programs, from scoping to maintenance, will favor pedestrians first, then transit riders, cyclists, and automobiles.”

So why am I focused on the bottom two modes in the hierarchy? Because this is where much of the fighting over street use takes place.

In Jefferson Park, the complete streets proposal is to reallocate space on a 5-lane arterial road which sees annual average daily traffic counts between 15,000 and 19,000 vehicles. One potential idea is to reallocate space from this:

milwaukee-avenue

 

 

to this:

milwaukee-avenue-road-diet

 

Of course, the road diet cross-section does not show blocks where parallel parking will still be allowed nor does it show the potential for street bump-outs, pedestrian refuge islands, transit lanes, and other features of complete streets, all of which are being examined.

So you might imagine the public anger that has erupted from seeing such a proposal. Because traffic actually moves well (really!) in this corridor, people don’t want to change its existing conditions – which also include gross violations (due to engineering design) of the speed limit, typically in excess of 1.5 times the posted 30 MPH limit or the fact that there have been 1,000 vehicle crashes in this mile long corridor over the past 5 (five!) years alone. Clearly the road is working well. So the road diet brings the accusation that the City will “take” space for cars and “give” it to bicycles (which have an existing painted 5-foot lane). This is what is truly unacceptable to many people (drivers) because roads are for cars, right?

Which brings me back to the fight over street space and bicycle use of that space. Vox.com recently wrote about why cyclists should legally be allowed to roll through stop signs and red lights (which is illegal in Illinois as in many other states but also which is commonly ignored by both police and bicyclists). I won’t get into the physics about why bicyclists do this only to note that it pisses car drivers off to no end who want to see enforcement of the law (like speed enforcement, right). But, as Charles Marohn of Strong Towns, who has provided me with significant insights on urban planning, has stated:

Stop signs weren’t designed for cyclists. In fact, very little of our built environment was designed with cyclists in mind. What we have done – as I pointed out way back with the video on the diverging diamond – is developed a tolerance for cyclists, and that only with some heroic effort. Engineers now generally accept cyclists and have even created checklists to help us accommodate them – at least the skilled ones – at a minimal level in our current transportation system. Tolerating cyclists, and sometimes even attempting to accommodate them, is a far cry from designing systems based on their needs.

We need to rethink our urban areas. They need to be redesigned around a new set of values, one that doesn’t seek to accommodate bikers and pedestrians within an auto-dominated environment but instead does the opposite: accommodates automobiles in an environment dominated by people. It is people that create value. It is people that build wealth. It is in prioritizing their needs – whether on foot, on a bike or in a wheelchair – that we will begin to change the financial health of our cities and truly make them strong towns.

So my response to my neighbors in Jefferson Park is that as long as we continue to design Milwaukee Avenue for the benefit of drivers, our community will always lose. We will not get the economic development we seek, for who wants to walk down a 5-lane arterial road with cars blasting through at 45 MPH? And our bicyclists, along with our pedestrians and transit riders will lose.

Urbanism and Resort Communities

I’ve spent the better part of last week in Sarasota, Florida, on Lido Key with my family to attend a wedding for my sister-in-law. Much has been written about sprawl throughout Florida or the housing crisis. What interested me was the urbanism I had found near the resort I stayed at, most unexpectedly.

St. Armand's Circle, looking west towards Lido Key.

The urbanism I’m speaking of was found on Lido Key and neighboring St. Armand’s Key. John Ringling (of Ringling Bros. fame) and Owen Burns purchased Lido Key, St. Armands Key and neighboring Bird Key in the 1920s and began a development scheme which eventually failed in the 1929 stock market crash. St. Armand’s Key has in its center, Harding Circle, shopping district oriented around a beautiful roundabout, which has been recognized on the National Register of Historic Places.

In the pictures, you may notice several features celebrated in new urbanism and planning circles alike: roundabouts, landscaped sidewalks and pedestrian treatments, all imposed on a grid street pattern.
These types of urban environments in resort communities are few and far between. I treasure spending time in these environments.

Smart Meters and Dumb Deals: What Chicago is missing out on.

Much has been said about the parking meter fiasco and how badly Chicago has been burned. I don’t have any more to add. Rather, I’d like to focus on missed opportunities in parking technology – opportunities at the meter that support urbanism and can generate real revenues for the city. Principally, this opportunity revolves around variable pricing policy.

While cars may be a part of urban life, free (or under-priced) parking does not have to be. Donald Shoup, author of the preeminent manual on the topic, The High Cost of Free Parking, states that planners tend to tackle street parking problems by increasing off-street parking requirements. “Rather than charge the right price for on-street parking, cities attempt to require the right quantity of off-street parking,” according to Shoup.

Chicago’s parking meter rates before the lease were low in many areas (they still are likely too low in some places). They were low because cruising and overcrowding of parking were the staples of urban life, particularly in many of the lakefront neighborhoods and downtown. Conversely, we know that if parking were priced too high, vacancies would be an issue. This is simple economics, the supply and demand curve (see below).

True market priced parking allow for free parking until an occupancy reaches 85%. This is due to the marginal costs of adding parking is zero, Yet, when demand (occupancy) increases, the marginal cost of adding additional parking increases. Because on-street parking capacity is fixed, costs must rise to meet demand. Thus parking costs should rise. This is what is called variable parking.

A smart parking meter, such as what has been installed in San Francisco, for example, can manage the availability of on-street parking by utilizing smart meters that can adjust prices dynamically, based on demand.

This technology is enabling not just better revolution of parking, but management of parking as well.

The problem with Chicago’s parking meter lease is not just that Chicago no longer controls parking, an important revenue generator in its own right, it is that the City gave up the right to control planning policy on some of the most vibrant land it owns – the streets. The City gave up the right to manage its on-street parking, to further planning goals and livability projects that create complete streets. Such projects might be pop-up cafes, bike lanes, street parades and festivals, all of which can reduce parking supply. And all of which are penalized under the terms of the parking lease.

The shame is that at the moment when parking meter technology  is revolutionizing the way cities manage parking, Chicago has turned over almost significant control over to a private company. The shame is that transportation planning is moving towards complete streets policies and Chicago finds itself without the flexibility needed to make its streets more livable and more complete.

 

 

 

CDOT Plan: Reaction

The Chicago Department of Transportation just released its Chicago Forward Action Agenda, which is the department’s strategic plan. You can read a good summary of it over at Grid Chicago and the full plan is available here. The plan has six elements. Here is my immediate reaction to the plan.

Safety

  • Eliminate all pedestrian, bicycle and overall traffic fatalities within 10 years.

I agree that traffic fatalities can be reduced and/or prevent through structural and design changes, but I think only to a point. We can’t control driver behavior. While this is a laudable goal, I don’t see funding to implement the changes that CDOT’s studies may suggest. Definitely not over 10 years. I do, however, appreciate additional study that could lead to small, but immediate safety improvements, particularly for bicyclists and pedestrians.

  • Reduce pedestrian and bicycle crash injuries, each by 50% within 5 years.

Another laudable goal, but what I’d like to have seen in the actions list is (and perhaps this falls under the Complete Streets policy) a re-engineering of the roads to slow down traffic. This could be accomplished through technology like speed cameras, but also through road diets and lane width shrinkage.

Rebuild and Renew

One area that is missing, and kudos for Grid Chicago for asking Gabe Klein about this, is partnerships with the other transit agencies besides CTA. And while I accept that CTA and CDOT have close working relationships for historic, political and practical reasons, the CTA is not the only mode of public transportation in the city. I’d love to see the city partner to improve commuter rail stations, both downtown and in the neighborhoods in as meaningful a partnership as the City has with CTA.

Choices for Chicago

I cannot emphasize enough how happy I am to read that the car “should be a choice, not a requirement.” This is true multimodal thinking! Let’s hope that the plan does not do anything to make it easier to drive in Chicago. It is already easy enough. While not the purview of CDOT’s silo, I would have loved to see an action item stating that CDOT would work with the Department of Housing and Economic Development  on land use and zoning issues that would support transit and bike/pedestrian modes better.

Sustainability

One of the coolest things that I’ve seen around downtown, highlighted in this plan, is the GreenStreets campaign, where the trees have “price tags” that illustrate the environmental value of the tree.

Fueling Our Economy

I think the very first performance measure, to increase activity, sales revenue, and occupancy rates in neighborhood commercial districts, is a fantastic example of breaking out of the silo. This is a problem that will have to be addressed city-wide through multiple agencies. Recognizing that streets can “add value”  to the neighborhoods means that you begin looking at streets in “complete” terms, as in how can a street serve multiple modes simultaneously?

This is it, for now. I’m happy to see CDOT embark on a strategic plan with a clear vision for what Chicago should be. I cast a critical planners eye, but I hope to convey that this is, however imperfect, a wonderful product. Now let’s see the implementation plan.

 

 

 

Speed Cameras and Complete Streets

I’d like to add a little more to the comments I posted on Grid Chicago regarding the speed cameras ordinance passed by the City of Chicago earlier this week.

As usual, the guys at Grid Chicago did an excellent job of reporting on the legislation and what it will (or won’t) do and I don’t intend on covering that. What I do think is important to highlight is the fact that too many streets in Chicago are built so wide as to encourage speeding. In my northwest side neighborhood of Jefferson Park, Milwaukee Avenue gets so wide north of the UP Northwest Line bridge that it is virtually impossible to travel the speed limit (30 MPH) without getting run off the road.

This type of road cross-section is what Charles Marohn calls a “complete road.” And it is designed for the 45 MPH world that is an engineering, fiscal, and urban design failure.

This is the problem with Milwaukee Avenue and for many of the major four lane arterial streets in Chicago. They are designed for quick movement of cars. Thus, a 30 MPH speed limit, which is the speed limit in Chicago where not posted otherwise, is a joke for cars. And it is dangerous for pedestrians and bicyclists.

If we’re really concerned about safety and about reducing pedestrian, bicycle and auto injuries and fatalities in this city, speed cameras are not the answer. Better design is. This is what I would recommend:

Reduce the width of the lanes to 10′ widths, perhaps even dropping a lane. Most of Milwaukee Ave. south of the UP-NW line into downtown is two lanes. This frees up room for the bike lane. In addition, there will be room for a median with protected pedestrian crossings. According to the National Complete Streets Coalition:

Complete streets reduce crashes through comprehensive safety improvements. A Federal Highway Administration review of the effectiveness of a wide variety of measures to improve pedestrian safety found that simply painting crosswalks on wide high-speed roads does not reduce pedestrian crashes. But measures that design the street with pedestrians in mind – sidewalks, raised medians, better bus stop placement, traffic-calming measures, and treatments for disabled travelers – all improve pedestrian safety. Some features, such as medians, improve safety for all users: they enable pedestrians to cross busy roads in two stages, and reduce left-turning motorist crashes to zero, a type of crash that also endangers bicyclists.

One study found that designing for pedestrian travel by installing raised medians and redesigning intersections and sidewalks reduced pedestrian risk by 28 percent. Speed reduction has a dramatic impact on pedestrian fatalities. Eighty percent of pedestrians struck by a car going 40 mph will die; at 30 mph the likelihood of death is 40 percent. At 20 mph, the fatality rate drops to just 5 percent. Roadway design and engineering approaches commonly found in complete streets create long-lasting speed reduction. Such methods include enlarging sidewalks, installing medians, and adding bike lanes. All road users – motorists, pedestrians and bicyclists – benefit from slower speeds

Complete streets encourage safer bicycling behavior. Sidewalk bicycle riding, especially against the flow of adjacent traffic, is more dangerous than riding in the road due to unexpected conflicts at driveways and intersections. A recent review of bicyclist safety studies found that the addition of well-designed bicycle-specific infrastructure tends to reduce injury and crash risk. On-road bicycle lanes reduced these rates by about 50%.
