Pedestrian Safety, Mapped: 2006-2015 Findings

Yesterday’s post began with the following questions: 

  • How ‘safe’ are pedestrians; 
  • What areas are less safe than others for pedestrians; and 
  • How can we work together to maximize safety and accessibility for non-motorized users of our transportation network?  

Using IDOT crash data for the City of Rockford, I put together the following:

1.jpg

From 2006-2015, 551 pedestrians were hit by the driver of a vehicle in the City of Rockford.

Rockford-Pedestrian-Fatalities.jpg

Of the 551 collisions, 23 were fatal.  (note: It is likely that these fatalities occurred at the scene. It is unlikely that IDOT has obtained data from area hospitals, so the number of fatalities may be higher). 

I explored the attribute tables afterwards.  I found that 56% of collisions happened in the daytime, not at nighttime (when people are often blamed for not wearing reflective, bright-colored clothing).  I also found that inclement weather–snow, rain, fog, wind combined–was present in only 18% of the collisions.   

Pedestrian-Collisions-C4.jpg

I then overlaid zoning districts onto the collisions. Pictured here is our C-4, mixed-use district, the most compact, walkable space we have in Rockford.   City Market, Friday Night Flix, Stroll on State…we have a lot of people out walking downtown.  Surely most of our collisions are happening in this district?  While not insignificant, only 15% of all pedestrian collisions occurred here. 

Pedestrian-Collisions-C1-2.jpg

Pictured here are a couple of our commercial districts.  This is where most folks are getting their groceries, cashing their checks, or dining out.  33% of all pedestrian collisions occurred here.  So what about these districts?  More particularly, what does the type of roadway bisecting these zones tell us about pedestrian collisions?

The city and our regional MPO have classified our roadways with seven designations ranging from ‘local streets’ to ‘interstate’.  The following slides show four of those roadways: Minor collectors, major collections, minor arterials, and other principal arterials.  Recall the hypothesis: 

Pedestrian collisions occur more frequently on principal arterial roads in the City of Rockford.

Less than 1% of all pedestrian collisions occurred on minor collectors.

Less than 1% of all pedestrian collisions occurred on minor collectors.

Just over 1% of all pedestrian collisions occurred on major collectors.

Just over 1% of all pedestrian collisions occurred on major collectors.

9% of all pedestrian collisions occurred on minor arterials.  Notably, Auburn and Broadway have a significant collection of collisions.

9% of all pedestrian collisions occurred on minor arterials.  Notably, Auburn and Broadway have a significant collection of collisions.

81% of all pedestrian collisions occurred on principal arterials.  We can accept the above hypothesis.

81% of all pedestrian collisions occurred on principal arterials.  We can accept the above hypothesis.

From 2006-2015, 81% of all collisions–446 out of 551–occurred on principal arterial roads in the City of Rockford.  Let me note the most dangerous roads in particular: 

  • State Street: 23% of all collisions (126 of 551) occur on State Street, which is owned by IDOT.  
  • 11th: 9% of all collisions (46 of 551) happen here. The highest concentration of collisions are on the portion of 11th that is also owned by IDOT. 
  • Charles: 8% of all collisions (39 of 551) happen here.

As you can see, these streets do a great job at moving a large number of vehicles every day.  However, they do a poor job at moving pedestrians. 

Tomorrow I will look at some of the design characteristics typifying arterial roads that frustrate pedestrian mobility and compromise pedestrian safety. 

 

Research: Pedestrian Collisions in Rockford

If you were to close your eyes and place a finger on any transportation-related document your city is producing, there’s a good chance you’d land on one word: Safety.

“The City recognizes the need to develop a safe, efficient, accessible and integrated multimodal transportation network that balances the need and desire for access, mobility, economic development and aesthetics while providing for the health and well-being for people of all ages and abilities.”  -City of Rockford, Complete Streets Policy, Jan 2017

These excerpts are from recent resolutions and agreements that the Rockford City Council has adopted.  All the right words are here: “multimodal”, “all ages and abilities”, “safe routes to school”, even “maximize carbon-free mobility”.  All good.

Recently my interest has been in the alignment of this municipal value–safety–with the existing conditions of pedestrian mobility.  I began with the following questions:

  • How ‘safe’ are pedestrians; 
  • What areas are less safe than others for pedestrians; and 
  • How can we work together to maximize safety and accessibility for non-motorized users of our transportation network?

January, 1974.

Every so often I would hear of pedestrians getting hit by drivers on certain roads.  So I began to research our library’s newspaper archive.  Turns out we’ve had a problem with pedestrian collisions for some time.  The above example in particular is telling:  Once a “comfortable country road”, Alpine Road has now sustained two pedestrian collisions in the last month…January 1974.  Over forty years ago.

Eventually it was time to pair qualitative research with quantitative research. I began with the following hypothesis: 

Pedestrian collisions occur more frequently on principal arterial roads in the City of Rockford.

So I obtained ten years of data from the Illinois Department of Transportation (2006-2015, to be exact).  Merged together, here was my initial finding: 

Rockford-Pedestrian-Collisions.jpg

From 2006-2015, 551 pedestrians were hit by the driver of a vehicle in the City of Rockford.

More to come tomorrow. 

 

A History of Traffic Safety in the United States: Part Four

This is a four-part series on the history of traffic safety reforms in the United States.  Part one is here, part two is here, and part three is here.

Analysis: Responsibility Paradigm, and the 21st Century ‘Traffic Fight’

Norton’s fourth paradigm, which covers the 1980s to the present day, bears similarities to the paradigms of the past.  Although the automobile industry remains governed by safety mandates, this paradigm elevates more responsibility to drivers for the safety of those inside and outside of the vehicle.  The ‘E’s of education and enforcement are instrumental towards this end.  For example, organizations such as Mothers Against Drunk Driving (MADD) and increased law enforcement penalties responded to the acute problem of drunk driving, especially in the 1980s.  Federal and state transportation departments have organized a number of awareness weeks ranging from work zone safety to distracted driving to “Start Seeing Motorcycles”.  The notion that safety is a “shared responsibility” between motorists and pedestrians re-emerged, and various state and local campaigns have encouraged the latter to wear reflective clothing and refrain from texting while walking.

An interesting feature of the responsibility paradigm is the deviation from the roadway as an automobile-exclusive utility and the willingness to reclaim the roadway for public spaces and other transportation modes.  Eric Dunbaugh refers to these roadways as “livable streets” that respect the adjacent urban built environment and improve the quality of pedestrian walkways. This approach to street design arguably stands in contrast to the engineering efforts in previous paradigms that were chiefly concerned with moving automobile traffic, mitigating congestion, and eliminating road hazards.  Indeed, the roadside design guides of the 1960s included such ‘forgiving design’ features as clear zones and removal of fixed hazardous objects such as trees within a certain buffer (Ibid, 287).  Dunbaugh contends that the design cues of “livable streets” are no less safe than the forgiving design approach, with the former being more context-appropriate in urban areas.  

Roadway reclamation within this paradigm includes both benefits and challenges.  Brian Ladd highlights the traffic-calming benefits that exist within shared roadway space.  John Pucher and Ralph Buehler mention that the most convenient bicycle facilities typically occupy space that was previously allocated exclusively to motor vehicles (2008, 512).  Peter Muller accepts that the automobile will remain in urban settings, but states that coordination with other transportation modes is a more effective response than building additional freeways (2017, 83).

Colin Divall’s idea of a “useable past” is especially salient for enriching the discussion around automated vehicles.  The previous paradigms demonstrate how Americans have used technology to improve safety outcomes throughout most of the 20th century.  During the “Safety First” paradigm motordom advocates argued that, in contrast to the horse and carriage, the handling and braking features of automobiles would actually improve traffic safety for pedestrians. During the 1939 World’s Fair, one of the vignettes of General Motors’ Futurama exhibit illustrated a remotely controlled driverless automobile with its passengers playing a board game.  O’Connell and Myers summarize a 1960s conference that outlined approaches to electronically control vehicles ranging from notifications inside the vehicle to fully automated driving that removes the driver from his previous responsibilities.  Underscoring this theme of automation is the shift from disciplining the driver to intelligently controlling the machine being driven.  Although such a shift would resonate with crashworthiness advocates of the 1960s, critics such as the head of engineering mechanics for General Motors argued that electronic implements are more fallible than human drivers.     

Any meaningful discussion on using the past to inform an automated future should include the potential redistribution of the roles and responsibilities of multiple actors including the driver, the insurance company, and the automobile manufacturer with its attendant electronics and software companies. Ethical questions abound: Which actors are culpable in a traffic accident?  How are ethical norms operationalized into computer algorithms?  Can computers negotiate in-the-moment ‘trolley problems’ that result in less harmful and more moral outcomes than a human counterpart? Will intelligent control further reinforce the idea of a street as a unimodal utility at the expense of more vulnerable, less equal roadway users?  The assemblage of power among automobile-oriented interests of previous paradigms suggests a useful precedent from which safety advocates in general and mode-specific interests in particular can learn.

This series provided a brief history of traffic safety reforms in the United States.  Using Norton’s four traffic safety paradigms as a framework for the series, I attempted to show how streets have and continue to be a contested space, not only with the advent of the “horseless carriage” but also with the imminence of automated vehicles.  From municipal traffic engineers to the National Safety Council and to automotive companies, the trajectory of traffic safety reform in the 20th century shows multiple actors using rhetoric, power, and organization to legitimate a particular mode, namely motorized vehicles, to the street.  The persistence of and continued interest in multimodal networks including bicycle, pedestrian, bus and light rail suggest that streets will continue to remain a contested space in the 21st century.

A History of Traffic Safety in the United States: Part Three

Crashworthiness Paradigm: 1960s-1980s

“We have drivers performing millions of maneuvers in their automobile adequately, even overpowering the deficiencies of their automobile…and then they make that one mistake, and should they die for that one mistake?…[W]e should build cars that take into effect that one, or those two mistakes…”  -Ralph Nader, U.S. Senate traffic safety hearings, 1965

During the 1960s, safety experts and congressmen began to criticize the efficacies of the ‘Three E’s approach especially in regards to its goal of optimizing driver behavior.  The issue of pedestrian safety was less apparent than in previous paradigms.  For many, the decades of educational campaigns, traffic engineering, and enforcement mechanisms were not successful in mitigating the number of vehicle collisions and subsequent fatalities.  Although fatalities declined during World War II in relation to war rations and the amount of vehicle miles traveled (VMT), the total number of deaths and the rate of fatalities per VMT increased during the 1950s and especially during the 1960s. In 1965, for example, vehicle fatalities totaled 48,000 persons, and that number would continue to increase into the 1970s.  So instead of the ‘collision avoidance’ proposition that was advocated in the previous paradigm, safety advocates shifted towards a ‘collision inevitability’ approach that recognized the range of errors that drivers are bound to make behind the wheel.  At a Senate hearing for encouraging new crash-worthy vehicle safety practices, Senator Abraham Ribicoff underscores the ‘collision inevitability’ approach with the following statement:

“The driver has many faults.  He is negligent; he is careless; he is reckless.  We understand that…I think it will be the millennium if you will ever get a situation where the millions and millions of drivers will all be perfect.  They will always be making errors and making mistakes.”

This should not be interpreted as a laissez-faire response to vehicle fatalities but rather as a distinct shift of responsibility from the driver to vehicle, or more specifically the automotive manufacturer.  If drivers would inevitably land on a spectrum between ineptitude and recklessness, then safety experts and advocates must work with automobile companies to reduce the effects of vehicular collisions and lower the risk of injury or death.  Jameson Wetmore describes how safety-oriented researchers and doctors began using the term “second collision”–that between the vehicle’s occupants colliding with the vehicle’s interior–as way to discuss overall risk reduction.  Structural reinforcements to the vehicle in addition to safety improvements within the vehicle’s interior would, according to safety advocates, decrease the intensity of occupant injury and likelihood of fatalities.

The automobile industry was hesitant to incorporate the crashworthiness approach into their business models. One reason was that the previous argument of auto companies–user error is the chief cause of traffic accidents–would be undermined by the positional shift.  Another reason concerned the company bottom line and the marketing efforts towards that end.  During the early stage of this paradigm a number of safety enhancements were proposed, such as collapsible steering columns and padded dashboards.  The “Big Three” auto companies (Ford, Dodge, and Chevrolet) contended that “safety doesn’t sell” and, according to Ladd, they did not include updated safety features as a means to keep costs down and remain competitive.  During the aforementioned Senate hearings, Senator Ribicoff argued that safety should not be optional features subject to marketing input but rather standard on all models: “It is a question of selling him safety or do you have a responsibility of producing a safe car with safety items?”

 In 1966 the National Highway Traffic Safety Administration was established.  The previous claims of the automobile being “perfected by science and industry” were no longer valid, and laws followed that would mandate safety features within new automobiles.  Notably, the total number of vehicle fatalities began decreasing into the 1970s and 1980s.

Control Paradigm: 1920s-1960s

“…[While] the automobile of today is as nearly perfect as science and industry can make it…the driver, figuratively speaking, is still wearing rompers.  He just hasn’t been able to keep up with improvements made on the road and the machine.”  

-John Maher, Mind over Motor

The education, engineering, and enforcement efforts of various entities within the prior paradigm were influential in lowering the rate of traffic fatalities.  Given the steady increase in driver registrations, however, the overall number of fatalities continued to increase into the 1920s and 1930s. In 1934, traffic fatalities increased almost 15% to a total of over 36,000 persons.  Rather than surmising a particular threshold of fatalities that would therefore therefore elicit political intervention, Steve Bernadin contends that “motordom members” were powerful enough to overcome divergent interests and rationalize the persistent problem of traffic fatalities. The primary way they did this was to absolve the vehicle–and its primary product of speed–from contempt and place culpability on the driver. 

 During this paradigm, industry reports, magazine articles, and even drivers’ manuals begin to describe the vehicle as a “perfect product”.  In his book Mind over Motor John Maher describes the automobile as “one of the finest products of the American age” while criticizing the driver’s ability to properly handle such a product.  Blanke quotes a 1937 drivers’ manual that describes the automobile as “nearly perfect as science and industry can make it…”.  The alleged accomplishments in automobile safety coupled with the advances in roadway engineering meant that the driver was the final element in attaining a safe driving environment.  Those who eschewed safe driving practices were characterized as inept at best and reckless at worst.  The former was assigned to both new drivers and non-drivers equally; young drivers must learn how to control and maintain their vehicle, while non-drivers must learn that the street is the domain of motorized traffic.  In this regard, both motorists and pedestrians could therefore exhibit reckless or careless behavior.  The more concerning issue, however, was not the inept drivers but the reckless drivers who in the words of Secretary Hoover were the “largest of the contributors” to the rising amount of fatalities.  It was these drivers to whom multiple organizations would appeal. 

Attempts to reach the reckless driver consisted of various voluntary appeals.  Some campaigns used pictures of mangled vehicles and deceased motorists to scare the driver into proper behavior.  Paul Hoffman, President of the Automotive Safety Foundation and former executive for Studebaker, viewed such campaigns as ineffective and propounded that scientific traffic policies are “a rational approach to an emotional problem”.  A collection of organizations researched methods and practices that would help identify the people groups wherein reckless driving may occur.  Jeremy Packer describes how psychologists developed character typologies and sociologists posited theories of estrangement and deviant behavior among adolescents.  Insurance companies paired their actuarial science with voluntary programs like the “Not Over 50 Club” which distributed vehicle stickers for drivers who presumably did not drive over 50 miles per hour. 

Although no longer exclusive to the NSC, the ‘Three E’s’ remained in service during this paradigm.  The role of education in training youth was especially heightened; not only were efforts to encourage playtime in park spaces reinforced, but training materials were geared toward young people with the assumption that they would eventually become drivers.  Regarding engineering, organizations created during the first paradigm (e.g. Institute of Traffic Engineers, American Association of State Highway Officials) worked with Congress to develop roadway studies and traffic safety reports.  The 1946 Action Program for Traffic Safety was a summation of accident prevention policies and practices that municipalities and safety organizations were instructed to use.  Local enforcement mechanisms were less the result of trial and error and more the recommendations of traffic engineers and city managers.  

During the 1940s, representatives of automotive interest groups including Paul Hoffman were looking for momentum at the federal executive and congressional level.  This was especially difficult as the realities of World War II were more pressing to lawmakers.  Nonetheless Hoffman and others worked with Presidents Roosevelt and Truman to advance automotive safety; they maintained that a free-flowing transportation network is crucial in both peacetime and wartime, and after World War II they recruited military leaders and declared a “war against accidents”.  The intent was to elevate the ‘Three E’s’ of traffic safety as an important issue for both congressman and their constituents, with the awareness of the latter encouraging the accountability of the former.  Using similar military-themed rhetoric President Eisenhower launched The Crusade for Traffic Safety in 1954, a media campaign designed to propagate the message of traffic safety throughout the country.  The campaign featured a pledge that included the elements of personal responsibility and morality indicative throughout the control paradigm: “I personally pledge myself to drive and walk safely and think in terms of safety.  I give this pledge in seriousness and earnestness, having considered fully my obligation to protect my life and the lives of my family and my fellow men.”
