The survey found that the cities - Toronto, London, Auckland, Singapore, San Francisco, Dubai and Stockholm - either reacted with a ban or left it open. And that the cities have been "proactive" or most reacted in retrospect to the change.

Stockholm was one of the cities with few regulations, which only started to react to the phenomenon afterwards.

- Compared to the others, Stockholm does not have a clear set of rules with regard to electric motors, says Hamza Harrami, who worked on the report.

"Before fines"

The consequence of this is, among other things, a negative opinion against electric scooters. WSP has suggestions on how to correct it and be able to keep the new traffic type.

- You should conduct a dialogue that will result in a clearer regulatory framework, which states, for example, where they may be parked. And that a penalty system is imposed if the rules are not followed, says Hamza Harrami.

The cities in the survey that had the least problem with the electric scooters planned in advance for the introduction, and also set a ceiling for how many electric scooters the operators were allowed to release in the urban environment.

Using knowledge is important

When Stockholm politicians are now debating whether and if so what should be done with the electric scooters, the call will be to do so with knowledge of how they are used in traffic.

Knowledge of where trips with electric scooters usually take place, and how long the trips are, is with the operators. Cities other than Stockholm have required access to that data and, for example, have been able to use it to point out parking spaces.

"It is the most important thing we try to get, that we use the data that is available," says Hamza Harrami.
