The USA is traditionally where the motor car is king as public transport has been sparse while roads have been built to cope with demand. But it is changing with some cities introducing Vision Zero to improve road safety and policies called “Complete Streets” and “Road Diets”. Vision Zero is well known in the UK as it has been adopted for example in London but with minimal or zero impact (see https://tinyurl.com/y39v6nsy for a previous article on that subject).
Complete Streets are designed to make it easy to cross the street, walk to shops, and bicycle to work. They encourage more walking, cycling and use of public transport. Road Diets involve reducing the number of traffic lanes to provide wider sidewalks (pavements) or the addition of cycle lanes and bus lanes.
Some cities such as New York are also considering introducing congestion charges to cut traffic and reduce congestion.
In other words, US cities are moving in the same direction as cities in Europe and copying London despite the fact that the policies in London have actually increased traffic congestion rather than reduced it and otherwise damaged the transport network. But opposition to such policies is growing. There are particular concerns about the impact on businesses and on access by emergency service vehicles, but there is general opposition to the increased traffic congestion such policies create. This web site covers the issue well and includes a video showing how fire tenders are blocked: https://tinyurl.com/y67gjzjg and emergency service vehicles delayed. It also has an interesting chart showing how the adoption of Vision Zero in Los Angeles appears to have resulted in an increase in pedestrian fatalities.
But opposition is growing. See this web site for a national view (which also includes an interesting note on the Delphi Technique to manipulate public opinion): https://www.keeptheusmoving.com/
In Los Angeles there is a local group opposing such measures who are holding a conference on October 5th – see https://www.keeplamoving.com/ . It’s some years since this writer personally visited Los Angeles but there was horrific traffic congestion then on some freeways and other roads. Reducing road widths to support cycling just seems nonsensical to support a very small proportion of the population when distances people travel to work or to shop is so high. US cities are designed around the use of motor vehicles and the population are not going to change their ways.
I won’t be attending the conference in person but I have submitted a short video which discourages US residents from following the path taken in Europe. Go here to view the video: https://youtu.be/LxEkiycYQ04
