The Transport Users

To get an overview of traffic flows, counts and mapping in the field is not always sufficient. If you need a better idea of the motives, preferences or opinions of the user, you need to ask them.

Tetraplan applies a wide range of methods to get the desired answers:

Traffic mapping and counts
Mapping and counting forms the basis of any assessment of effects on traffic. Tetraplan applies a number of different mapping techniques, depending on the project. We have implemented manual counts, license plate analysis, stop-interviews and postcard questionnaire type of mapping. 

National Transport Survey
The National Transport Survey is a well of information: Who is on the busses, riding the bikes, where are they going, and how does employees get to work?. Tetraplan has extensive experience in using information from the National Travel Survey. 

Questionnaires
Web-based questionnaires are often a quicker and cheaper means of getting information from larger groups of people. Both for collecting quantitative information and more qualitative comments, e.g. to give direction for a new bus plan, infrastructure project or a strategic plan. Tetraplan is using internet based questionnaires both in a scientific context (ensuring the right sample) and in more informal hearings, where input give direction but not decision. Tetraplan has also experience in setting up Stated Preference analysis. 

Focus groups
Focus group interviews give good insight in complex, and perhaps less explored problems. Tetraplan conducts focus group interviews in many different projects where the interaction between the participants benefits the process.
