Helmet study fails to consider denominator and confuses science with policy

Via Washcycle

Of course there are problems with this because it just counts raw numbers.

It doesn’t consider if states with mandatory helmet laws have less cycling, and of course there is evidence that mandatory helmet laws do reduce cycling. So we have the numerator (injuries/deaths) but not the denominator (cyclists or miles biked). Here is another study that showed the same thing, but considered the change in cycling. 

 In recent years, many states and localities have enacted bicycle helmet laws. We examine direct and indirect effects of these laws on injuries. Using hospital-level panel data and triple difference models, we find helmet laws are associated with reductions in bicycle-related head injuries among children. However, laws also are associated with decreases in non-head cycling injuries, as well as increases in head injuries from other wheeled sports. Thus, the observed reduction in bicycle-related head injuries may be due to reductions in bicycle riding induced by the laws.

New Older Driver Safety Organization


AFODS Newsletter 
April 2013

 NEW ORGANIZATION TO ADVOCATE FOR SAFER ROADS

Welcome to the inaugural issue published by the newly launched national organization, Americans for Older Driver Safety, a non-profit project of KIDS AND CARS, Inc. Susan Cohen and Mitchell Krasnopoler founded Americans for Older Driver Safety (AFODS) following the 2011 death of their 20-year-old son, Nathan. An 83-year old driver making a right turn crossed into the bicycle lane where Nathan was riding resulting in the crash that took his life. The mission of Americans for Older Driver Safety is to advocate for safer roads for older drivers and all Americans, through driver education, assessment, retraining and transitioning; and to raise public awareness of the safety risks related to unmonitored changes in driver abilities. After more than 20 years as a practicing attorney, Susan Cohen left the Maryland Office of the
Attorney General to lead AFODS and promote best practices, good ideas and top-notch research and ensure that all drivers have the functional ability to drive. Based in both Maryland and the Midwest, AFODS has had a significant impact over the past year raising awareness and advocating for safer roads across the country.  Some of the highlights and accomplishments are described below.

AFODS PUBLISHES 2013 POLICY BRIEF
Older drivers are expected to triple in number over the next fifteen years: Road safety policies are needed now. Federal recommendations, national and state-based research, and rapidly changing demographics indicate that changes to state driver licensing practices and highway policies are needed to address older driver safety.  Best practices suggest that older drivers should be renewed in-person every two years to identify changes in cognitive and physical function that affect driving. States across the country have begun to shorten driver license renewal periods for older drivers to every two years. For more read the 2013
Policy Brief: Maryland’s Older Drivers: Ensuring Road Safety.
  

AFODS HOSTS MARYLAND LEGISLATIVE BRIEFING 
In February 2013 AFODS hosted a legislative briefing to inform members of the Maryland General Assembly on older driver safety concerns with Maryland’s eight-year renewal periods.  In light of the rapidly changing demographics that will double the number of Maryland drivers over 70 in just seven years and more than triple the number of drivers over 70 in 15 years, the briefing looked at the need to improve Maryland’s older driver license renewal process. Counter to the trend in other states, in Maryland there are currently no special provisions in place for older drivers. Maryland drivers renew every eight years and in-person renewals are required every other renewal, or every 16 years.  A driver renewing at age 70 is not required to return to an MVA office for renewal until age 86.  The research shows that older drivers become more crash prone with age, even though they drive less.  Age-related declines in vision, physical
mobility, reaction time, and cognitive processing affect the driving ability of some older adults. Based on research showing how aging negatively affects driving abilities, the U.S. Dept. of Transportation has issued recommendations to states to modify licensing procedures for older drivers that include shorter renewal periods and in-person renewals.  Maryland’s practices, as of 2012, put Maryland far afield of those traffic safety recommendations. 

AFODS IN MISSOURI 
At a March 20, 2013 press conference in Columbia, Missouri, Susan Cohen, AFODS Founder, was part of a five-member panel addressing safety concerns of older drivers and the need for some drivers to move to  alternative mobility options.  The purpose of the event was to highlight a new pilot program, Mobility Transition Counseling, to facilitate transitioning from driving to other mobility options.  The Missouri Coalition for Roadway Safety, Subcommittee on Elder Mobility and Safety (SEMS), meets quarterly to address road safety concerns of older drivers and uses the slogan, Arrive Alive After 65. 

AFODS IN KANSAS
In Kansas, AFODS will join a support team on older drivers that has been formed by the Kansas Department of Transportation to determine actions to take to reduce older driver injuries and fatalities as part of the Kansas Strategic Highway Safety Plan.  The support team includes representatives from AAA, AARP, University of Kansas Transportation Research Institute and other stakeholders and experts. The team will issue a final report identifying steps to take to reduce older driver crashes.

Your Bike Helmet Doesn’t Do What You Think It Does.

Bicycle helmets do an outstanding job of keeping our skulls intact in a major crash. But they do almost nothing to prevent concussions and other significant Brain inJuries—and the very government agency created to protect us is part of the proBlem. the time has come to demand something safer.

For more than thirty years, medical researchers have known that concussions occur because of brain spin, not blunt force. Helmet makers ignored the concussion problem because they assumed they couldn’t solve it, and their customers didn’t much care. Riders assumed they were safe because the government certified every helmet sold. What they don’t know is that the government standard is the very thing that prevents helmets from getting better — and addressing the concussion problem.
And that problem is getting worse. The death rate for bicyclists has steadily declined over the past 15 years. The concussion rate for bicyclists is going the other direction. It’s growing faster than the sport.
The good news: There is a solution. It’s available on the shelf today. You just have to know where to look.

NHTSA: Traffic Deaths Shot Up 5.3 Percent to 34,080 in 2012

by Tanya Snyder, Streets Blog
Deaths from motor vehicle crashes rose 5.3 percent in 2012, according to new numbers from the National Highway Traffic Safety Administration. It’s the first time since 2005 that fatalities have gone up. Vehicle miles traveled only rose 0.3 percent last year.

Fatalities rose the most in the northeast (>15 percent)…

Who Should Pay for Transportation Infrastructure? What is Fair?

by TODD LITMAN, Planetizen

The root of the problem is that automobile transportation is costly – more costly in total than other modes. Motorists spend, on average, about 18% of their income on their vehicles and fuel, and about 10% of their housing costs for residential parking. This heavy cost burden makes motorists selfish; they often argue that somebody else should bear the costs of road and parking facilities in order to make driving affordable, and that no transportation funds should be "diverted" to support other modes. As a result, alternatives are underfunded: although 10-15% of urban trips are made by walking and cycling, non-motorized modes only receive 1-3% of total transportation funding, and far less if parking facility costs are also considered. A better solution than increasing subsidies for driving is to invest more in affordable modes, particularly walking and cycling facilities, in order to reduce total transport costs.
