Study: Protected bike lanes in northern Kansas City slowed traffic and increased cycling

Preliminary data showed that adding sheltered bike lanes along a busy road that runs through downtown North Kansas City, Missouri, would improve safety and increase bike traffic, new report From Streetlight data found.

North Kansas City, a small town surrounded by Kansas City, Missouri, has added sheltered bike lanes along less than a mile stretch of Armor Road. The project – Part of the largest Entire streets City Effort – Brightly colored footpaths, landscapes, and pedestrian islands, among other improvements, have been added.

Streetlight Data, a company that provides mobility analytics, Measure the size and speed of movement From January to March 2019, before the city added bike lanes, and again during the same time frame in 2020 and 2021, after installing them.

The data indicated that the new bike paths succeeded in several measures.

Streetlight did not examine whether the project affected collision rates, but found that the cars were traveling more slowly. Before bike lanes, about 5% of cars traveled more than 40 mph on this stretch of road, well above the 25 mph speed limit. After that, almost no cars traveled that fast.

Meanwhile, bike traffic more than doubled, from a daily average of 50 to 114. The report notes that bike traffic did not decrease on a parallel road that was used as a project control during that period, indicating that more people were They ride, do not transfer from the neighboring streets. However, bikes accounted for only 2% of traffic along Armor Road after bike lanes were added.

Streetlight ran the study from January to March, which is the off-peak cycling season, but “this increase is noticeable, and I think the data supports that,” said Emily Adler, Streetlight’s director of content. The epidemic hits in April [2020] The months “affected the chosen ones,” she said.

On the downside, the congestion on the street has risen. “When looking at the crowding rate, or the percentage of hours of day that crowding occurs, there was a slight increase from 13% to 20% between the 2019 and 2020 study periods. However, in 2021, the congestion rate declined again to 18%, according to To report Streetlight Data on its findings.

Streetlight chose this location as an experiment and was not a city partner. Xue Wood, North Kansas City’s director of community development, said she was unaware of the Streetlight data.

It was several cities Network building of protected bike lanes in recent years, including New York City, Pittsburgh, Philadelphia, Chicago, and Washington, D.C.
