More than 3.8 million people commute to work via bike in the Bay Area each day, according to a new study.
The figure represents a record high for a single-year period, surpassing the previous record set in 2017.
The study, conducted by the Department of Transportation and the California Department of Motor Vehicles, was based on information from a survey of more than 1,400 commuters and bicycle operators.
It found that in 2017, the share of drivers who said they used a bike for work was about 30 percent higher than the share who used a car.
The share of cyclists who commuted on a bike doubled from 19 percent to 29 percent in that time period.
It was the first time since the survey began in 1995 that a share of commuters who commutes on a bicycle surpassed that of car commuters.
“This year, there is an increase in the number of people using bikes in their commute to and from work,” said Dr. Michael Schramm, director of the Department for Transportation.
“I think it’s very significant and a positive sign.”
The study was conducted for the state Transportation Department.
It has been released by the state Department of Public Works and Highways.
Transportation officials and bike advocates were quick to note that this is a good sign, but some people will likely disagree with the findings.
“It’s good that we’re seeing this increase in ridership and more people riding bikes, but we still need to see that we can make biking a viable mode of transportation,” said Marcia Clark, executive director of Bike San Francisco.
Clark said it’s too soon to tell how many people will be using bicycles by 2025, as transportation officials still need more information to determine if the increase is sustainable.
Clark pointed to the Bay Bridge as an example.
The bridge is now under construction, but it is expected to be completed by 2025.
She also noted that the state is currently funding about $1 billion to help expand bike infrastructure in the state.
“Bike advocates will need to continue to work on the implementation of the Vision Zero plan and to build infrastructure around the Bay,” Clark said.
“But it’s great to see the increase in cyclists on bikes.
We’re going to see more of them.”
In a separate study released Wednesday, the University of California Transportation Institute found that the share that commute by bike has increased more than 100 percent over the last four decades.
The institute looked at data from the U.S. Census Bureau and other sources, including a recent survey of 9,400 people from more than 2,000 bike shops.
The bike share program that the institute runs has more than 25,000 stations in more than 160 cities in California and is part of the state’s $9.8 billion $2.5 billion transportation fund.
The U.C.T.I. report said that since the late 1990s, bike use in the U,S.
has increased at a rate of nearly 300 percent.
The number of bike commuters has also increased significantly, the report found.
