Johns Hopkins: Narrow Lanes Save Lives

- Adam Clare

Johns Hopkins has reached a conclusion: to protect lives we need to narrow lives. Cars kill. Cars (and the people driving them) are more likely to cause death when they move fast and wide lanes encourage speeding. A logical step to curb reckless driving by car drivers is to limit the space they have to drive cars, and make the space they drive in more interesting. By narrowing lanes there are many benefits to be had by society at large. It’s good to see an institution like Johns Hopkins has figure out that car focussed design is not a good thing – streets are for people.

  • Narrower lanes did not increase the risk of accidents. When comparing 9- and 11-foot lanes, we found no evidence of increased car crashes. Yet, increasing to 12-foot lanes did increase the risk of crashes, most likely due to drivers increasing their speed and driving more carelessly when they have room to make mistakes.
  • Speed limit plays a key role in travel width safety. In lanes at 20-25 mph speeds, lane width did not affect safety. However, in lanes at 30-35 mph speeds, wider lanes resulted in significantly higher number of crashes than 9-foot lanes.
  • Narrower lanes help address critical environmental issues. They accommodate more users in less space, use less asphalt pavement, with less land consumption and smaller impervious surface areas.
  • Narrowing travel lanes could positively impact the economy. This includes raising property values, boosting business operation along streets and developing new design projects.

Mobile Pollution Boxes Need to Pay to Enter Manhattan

Cars take up a lot of space in urban centres and deprive non-car owners of previous real estate and a clean environment. Yet, for years we have let car drivers occupy our cities with their large metal boxes which impeded the freedom and mobility of others. Back in 2003 London put in place the first congestion charge for their downtown and since then many cities around the world have followed. However, in car brain North America the idea never took off. Until now. New York City will be implementing a congestion charge for Manhattan starting this spring.

Experts see the measure as a first step in the right direction. They believe the toll will help fund the city’s ailing subways and buses, and make the streets of Manhattan a friendlier place. It is also seen as an opportunity to put an end to the car culture in a city — perhaps the only one in the United States — that is perfectly accessible by public transportation, with the exception of isolated peripheral areas. Indeed, for this reason, some have said that the measure is not ambitious enough, arguing that it should apply to the five counties of New York.

“You have to start somewhere, and this is a great start,” says Howard Yarus, of the District 7 transportation committee. The group he represents proposed a plan in 2019 to eliminate free street parking, an unthinkable change for the urban landscape. “Until now, if I took my car, which pollutes the environment, to go downtown I didn’t pay anything, not even when parking. But if I went by public transportation, it cost me $2.90 [for a subway or bus ticket]. As a public policy, that seems terrible to me.”

France Pays People to Stop Driving and Start Riding

Car drivers take up way more road space than they need since the size of their vehicles are disproportionate to their usefulness. Smart countries aim to limit the number of single occupant vehicles on the road for this reason and to ensure that all people can easily get from one place to the next. Traffic is so bad in some places that countries, like France, are now paying people to give up on their car.

France is working hard to push urban drivers out of cars and towards smaller and more environmentally responsible forms of transportation. In large cities like Paris, reduction in traffic from a switch to bicycles and scooters is perhaps just as important to many residents as the environmental effects.

We recently covered the case of an electric bicycle company that is switching from vans to cargo e-bikes to increase the number of electric bikes it could deliver each day. The company’s delivery vans were simply too slow in Paris traffic, and switching to cargo e-bikes will help ramp up deliveries by using smaller, quicker, and more efficient vehicles.

Another Urban Myth Busted

Road users always complain that other people are breaking the law, every group of road users accuess another of breaking the most traffic rules. Truckers think cars are the worst, car drivers think cyclists are the worse, and cyclists think all vehicles are bad.

When it comes to an objective analysis of which category of road users are the worst: it’s the car. Bicyclists are the least likely to break laws.

Welcoming the new video study, the Danish Cyclists’ Federation tweeted its pleasure that, again, evidence showed that “cyclists are not lawless bandits.”

Studies elsewhere in Europe have previously found that the image of the law-breaking “Lycra lout” is wrong. A Transport for London study investigated the “hypothesis that the majority of cyclists ride through red lights” and discovered that 84% of cyclists stopped on reds. The study concluded that the “majority of cyclists obey red traffic lights” and that “violation is not endemic.”

Reducing Traffic Pollution Greatly Increases Health

It’s well known that vehicular traffic is deadly no matter where it is and how much of it exists. Even with all the evidence cities in North America put cars first with the occasional protections like bike lanes and pedestrian crossings. What we also need to talk about is the threat cars bring to our lungs.

The Canadian Association of Physicians for the Environment have released a report outlining how many health gains come from eliminating cars from our streets. Electric cars aren’t the solution because they are still only focused on single occupants and give off particulate matter when braking.

Recommendations for achieving those benefits include stronger fuel content and vehicle-type rules, restrictions on idling and the use of vegetation barriers along busy roads. Cities can also implement low-emission zones that favour electric vehicles, bicycles and public transit. Ventilation systems in buildings, which became a focus during the pandemic, can play an important role in preventing traffic-related pollutants from infiltrating indoor spaces.

But like many pollution issues of the past century, effective solutions typically require governments to motivate change.

“Problems like this just cannot be tackled at the individual level,” Dr. Green said. “If an individual is concerned about this issue, then they need to demand that their politicians take action.”
