Real Time Street Level Vehicle Exhaust Emission Monitoring

A team of researchers have used the NYC traffic congestion charge as a place to test out some of their hypothesis. Spoiler: the city got better and air quality improved. The research team were able to figure out how to monitor pollutants on individual streets instead of neighbourhood or city-wide levels. They used cameras and phone data to track traffic (removing personally identifiable information). Their method has increased monitoring accuracy and showed that previous pollutant monitoring solutions could vary widely by up to almost 50%

It also helps with better modelling by figuring out which transit options will reduce pollutants the most.

For one, they modeled what would happen to emissions if a certain percentage of travel demand shifted from private vehicles to buses. In another scenario, they looked at what would happen if morning and evening rush hour times were spread out a bit longer, leaving fewer vehicles on the road at once. They also modeled the effects of replacing fine-grained emissions inputs with citywide averages — finding that the rougher emissions estimates could vary widely, from ?49 percent to 25 percent of the more fine-tuned results. That underscores how seemingly small simplifications can introduce large errors into emission estimates.
…
To study that, the researchers looked at what happened to vehicle traffic at intervals of two, four, six, and eight weeks after the program began. Overall, congestion pricing lowered traffic volume by about 10 percent — but there was a corresponding drop in emissions of 16-22 percent.

Cleaning Urban Air is Simple and These Cities Have Already Done it

Since 2010 19 major cities have “remarkably” reduced their pollution so much that it some people are shocked by it. The tracked pollutants have dropped by 20% or more in the cities, which include Paris, San Francisco, and Beijing. The commonality between the cities achieving a remarkable reduction in pollution is thanks to reducing cars, reducing cars that burn fossil fuels, adding green space, and ensuring that people can choose sustainable transportation options. It’s so simple that any city anywhere can follow these solution to clean their own air.

The analysis found interventions such as cycle lanes, uptake of electric cars and restrictions on polluting vehicles had helped to drive the improvements.

“Air pollution is often presented as a problem that is too difficult to solve and one that is politically unpopular,” said Dr Gary Fuller, an air pollution scientist at Imperial College London, who was not involved in the report. “This report shows that bold policies can improve the air that we breathe.”

The Simplest Way to Improve Cities: Remove Cars

For the last 100 years streets have been destroyed by the automobile and corporations that profit from excessive use of cars. This has caused harm to the wellbeing of people both in and outside the cars as well as countless environmental issues. It does not have to be this way, and cities from Paris to Seoul have shown us that we can modify our cities to reclaim them from the scourge of the automobile industry. Over at Fast Company they have a nice list of five things cities can do to improve life for everyone in the.

Reversing car-centric design is not a utopian dream. Cities around the world are already doing it. Paris is removing 70,000 parking spaces to make room for bikes and trees. Barcelona is expanding its network of “superblocks” that prioritize pedestrians and eliminate through-traffic. Oslo removed cars entirely from its city center and saw foot traffic, and local business, surge. Cities in the Global South are pioneering new forms of green micormobility, such as Jakarta where the government has set a target of electrifying 2.1 million motor cyles by the end of 2025

Johns Hopkins: Narrow Lanes Save Lives

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.”
