I previously share articles on whether bike lanes cause more traffic. This question has been asked so often as we have returned to the “old normal” levels of traffic and bike lanes that were put up during the pandemic have been neglected or removed in favor of motor vehicle traffic. The perception for those in-charge of traffic and transportation in local government units is that the space occupied by bike lanes take up the space demanded by motor vehicle use. Thus, the view that bike lanes cause congestion. Here is another article share in support of bike lanes:
Mortillaro, N. (October, 2024) “Do bike lanes really cause more traffic congestion? Here’s what the research says,” cbc.ca, https://www.cbc.ca/news/science/bike-lanes-impacts-1.7358319 [Last accessed: 01/11/2024]
To quote from the article:
“One would think that building more roads with more lanes for cars would reduce congestion, but research shows that’s not the case, thanks to something called induced demand. The more traffic lanes that are put in, the more it appeals to people who may not otherwise have chosen to drive, thereby putting more cars on the roads and increasing congestion.
“So for a short period of time, there might be a slightly improved [reduction], but within a year or two, or perhaps three, traffic is as bad or worse than it was before the lanes were added in the first place,” said David Beitel, data services lead at Eco-Counter, a Montreal company that collects and analyzes pedestrian and bicycle traffic data.
Conversely, if you put in more dedicated bike lanes, people tend to feel safer and demand for use increases, said Shoshanna Saxe, an associate professor at the University of Toronto’s department of civil and mineral engineering and Canada Research Chair in sustainable infrastructure.
“As soon as you build a bike lane, within a year, two years, the latent demand shows up,” she said.
Bike Share Toronto statistics show that ridership on its network of shared bikes has increased dramatically since 2015, when 665,000 bike trips were made annually. In 2023, that shot up to 5.7 million trips.”
I think many people here are already aware of the concept of induced demand. However, this is usually shrugged aside as realities in their situations (e.g., commuting options, locations of residences and workplaces, etc.) lead them to choosing private vehicles (i.e., cars and motorcycles) over public or active transport. The last paragraph there is significant though as there never was and so far a decent estimate of bike trips in any city in the Philippines. Granted that there are attempts to measure bike trips but the volumes published so far are not as reliable as we want them to be in order to be convincing decision-makers to put up more bike lanes. Of course, the convincing part is always challenging if decision-makers have already made up their minds in favor of the car.
