Burlington Roundabout Cure for Signalized Intersection Highway Deaths

Burlington Intersection Death List...Our Recent History of Fatal and Serious Injuries...Now Modern Roundabouts Cut Fatal/Serious Injury by About 90 Percent 

The National Picture of Highway Safety

About 9,000 fatals--23% of the over 40,000 annual highway deaths--occur at or near intersections.  Half of all senior driver and pedestrian deaths involve intersections.  For every U.S. fatality there are about seven disabling injuries.  In 2003 U.S. pedestrian deaths and disabling injuries, included in the US highway totals, amount to 20,700 and bicyclists numbers were 6,600.  Unfortunately since 2010 US pedestrian deaths are up 45% nationally.  Once 1st in highway safety in 1990, the U.S. has fallen to 18th.  Based on highway miles driven we now have over 23,000 excess deaths compared to the performance of the top four nations—U.K. (co-leader with us in 1990), Norway, Sweden, and Switzerland.   In a recent year highway crashes were the highest cause of death for those aged 4 to 34.  

The Vermont Highway, Gun, Opioid Deaths Data

Current U.S. longevity decline, the only one among advanced nations, coincides with the extremely high rates and numbers of highway, gun and opioid deaths:  over 40,000 highway deaths (2018), 39,800 gun deaths (2017), and 70,000 opioid deaths (2017-2018 average).  Vermont death numbers are 69 highway (2017-2018 average); gun 78 (2016); and opioid 109 (2018).  (Alcohol addiction remains far and above these three causes of death in U.S.)  For highway safety, returning Vermont and the nation to number one would halve Vermont highway fatalities, a reduction of about 35 a year.  Adopting neighbor Massachusetts gun regulation, lowest in nation in gun deaths, would reduce our gun deaths up to two-thirds, about 40 less deaths per year.  Certainly opioid reduction efforts can very likely attain a 50% reduction or 55 deaths a year.  Overall the estimated potential reduction in highway/gun/opioid deaths totals 130 a year.  All three areas require equal, aggressive governmental attention at the local, state and federal levels.  

First and foremost in regard to highway safety the United States and each state—Vermont can take this action now—must undertake a “systematic safety” plan and program, a comprehensive planning and implementation plan which led several advanced nations past the U.S. in highway safety performance and even in many cases continues to widen the gap with the United State.  The local equivalent of “systematic safety” can take the form of a strong “Vision Zero” initiative but to this time Vision Zero initiatives have been at most halfway measures. 

The Burlington Picture of Highway Safety

The Burlington roadway deaths and injuries show a need to address pedestrian and bicycle carnage because these latter two modes not only are more prevalent in urban areas but because there are strong currents to expand these “active transportation modes” for health and environmental reasons.  In addition to safety as the first and overriding concern, consideration of global warming, air quality, and resource constraints are now recognized as a given in transportation investments decision making. 

Burlington clearly is not immune to deaths and injuries at our intersections.  Burlington recently averaged 150 roadway injuries yearly including a pedestrian and car passenger fatality in the 2014-2018 period.  About a third of annual injuries, about 50, comprised those on foot or bicycle in roughly equal proportions.  Most pedestrian injuries occur at intersections.  Two of the three pedestrian fatalities in Burlington dating from 1998 were at a signalized intersection as was the one cyclist fatality.  A survey taken as part of the PlanBTV Walk Bike adopted in 2017 found (2011-2015) found 17 intersections (“the dirty 17”), mostly signalized, averaging one injury a year—again including a pedestrian fatality in the survey period.  Burlington has three of the highest current Vermont Agency of Transportation (VAOT) crash intersections in Vermont—Colchester/Barrett/Riverside US 7 (#1); Main/S. Prospect US 2 (#16); and Pearl/ N. Willard US 7 (#27).  The only reason the Burlington intersection Shelburne/Locust/S. Willard/St. Paul is no longer on the list is because it is set for construction as a roundabout.   

Burlington from 1998 through 2018 recorded seven road fatalities, about one every three years.   All but one of the seven occurred at a signalized intersection: three car occupants (two drivers and a passenger); three pedestrians; and one bicyclist.  With 150 injuries a year in a five year survey period, it fair to conclude that about one fatality occurs here for about every 450 injuries.  Again, six of seven fatalities occurred at one of the City's approximately 75 traffic signal intersections.  Finally, it is the pedestrian and bicyclist who suffers disproportionately when it comes to fatalities versus the car occupant who retains the protections of a motor vehicle—while pedestrian and cyclist injuries in Burlington are one third of all injuries, when it comes to fatalities they are the majority, four of seven.   

The Modern Roundabout Cure

The modern roundabout, the 53 year-old powerful technology composed of stone age materials, cuts about 90 percent of fatalities and serious injuries as well as injury severity  (Insurance Institute for High Safety [2000]).

Below find added information on Burlington fatal crashes at intersections, only some of the recent fatalities statewide and a small fraction of critical injuries at Vermont intersections.  The signalized intersections appear good candidates for roundabouts. Vermont passed the first US state legislation in 2002 calling for a transportation department to aggressively pursue installing roundabouts at dangerous intersections. 

Roundabouts in downtowns and village centers in Vermont are a proven safety treatment.  The five Vermont downtown roundabouts (Manchester Center, Middelbury and Montpelier) in their first 52 years of performance recorded zero bicycle injuries, one pedestrian suffering bumps and bruises and four minor car occupant injuries—one injury (none serious) a decade.
Several jurisdictions—states, Canadian provinces, counties and cities—have adopted “roundabouts first” policies.  NY State Department of Transportation is certainly the most prominent with its “roundabouts first policy” in place since 2005.  

In a 2011 report, AAA called for a White House Conference of all interests and adoption there of a “zero fatality rate” goal on the nation's highways.  That AAA study done by the reputable Cambridge Systematics found highway fatality and injury social costs twice the cost of congestion in all but the smallest metropolitan areas—and higher in all metro areas.  The Federal Highway Administration uses a highway fatality social cost as $6.1 million and an injury $126,000 (2009 dollars).
