During August and September 2018, cycling habits in Lund were investigated through the TravelVu app and the Tryk til campaign. The results were analyzed through a special visualization project. In October 2019, Luk Knapen and Johan Holmgren at Malmö University also presented how to make mathematical models to join together places marked as unsafe by the cyclists.

“Our analysis of the collected material has shown that the TravelVu app and the Tryck-to campaign provide a good basis for a survey of cyclists,” says Luk Knapen in an interview in October 2019. I think the survey could be developed if you combined the values that Tryk-to gave with more background data on, for example, age and gender.

Malmö University had, among other things, developed methods to identify different clusters where cyclists stated that they felt unsafe. It was both about locations and about distances.

For the technical administration in Lund, the result of the bicycle project was interesting and Erik Nilsgart and Helena Runesson have been involved in the project from the very beginning. The administration studied the clusters identified by the university to understand what creates insecurity.

“Some of the clusters that we were able to see from the report we have looked at extensively and tried to find possible reasons why people have experienced uncertainty in traffic,” said Erik Nilsgart. Most of the clusters we believe are due to temporary solutions such as a temporary passage during construction of the tramway. In other places, we are a little surprised as the points contain all road safety solutions such as speed reduction measures, separated bike lanes and more. These clusters need deeper analysis so that we can possibly understand how they can be perceived as unsafe.

“We have made a list of possible causes for all of the clusters presented in the report and will take a closer look at the ones that we found most interesting,” said Helena Runesson. To understand this, site visits will be made but it may still be difficult to understand whether it is, for example, the physical layout or the behaviour of other road users that is perceived as unsafe.

Part project manager for the bike project was Emeli Adell at Trivector. When both the visualisation project and Malmö University's analysis were completed, she was satisfied with the results.

“I think you can say that it worked well,” says Emeli. It's exciting ways to get new kinds of data, to get to see where cyclists cycle and where they feel unsafe. Among other things, we have found interesting differences in the way men and women use electric bicycles. Men cycle about the same length and length of time with an electric bike as with a regular bike, while women both cycle significantly longer distances and time with an electric bike compared to a regular bike.

The collection of data is part of the cycle projects within the SOM project that was implemented in 2017-2020 with the support of IoT Sweden
