The volume of traffic in the city of Olten is recorded at nodes and cross-sections every 5 years, simultaneously and conceptually coordinated with the cantonal traffic count.
WAM designed the census concept and organised the implementation of it on behalf of the City of Olten.
On 16 September 2020, around 400 high school students were on duty at 34 counting points in the city.
The evaluation of the survey is still pending.
