Data from travel surveys is underutilised. Travel data can help provide insights to many actors working in the mobility sector. Most often only simple summary statistics in static reports are used, and the underlying data and database are not used to their full potential.
That’s why Trivector has developed the web-based tool TravelViewer, which makes it possible to easily ask questions to the data collected using the TravelVu app. It is a dynamic encyclopedia instead of a static report. The tool consists of three different parts/functions: recruitment, weighting and analysis.
During data collection, you can follow the data collection and see how well those included in the survey match your target population. In this way, you will have the opportunity to adjust any further recruitment in the survey so that the sample represents the larger group as well as possible.
During recruitment, you can choose and fill in characteristics (e.g. gender and age) of the target population.
In the Analysis function, key figures for travel per person are displayed as well as mean values of more mode share distribution, trip purpose distribution, trip lengths and travel times per trip and the distribution of travel over days of the week. You can also analyse background questions.
With the help of various filters, you can easily select which transport modes, activities (trip purpose) and/or time period you want to study. You can also filter based on answers to the survey questions.
This is relevant really only for larger data collections, and when you are want to make statements of how a target population behaves. In this case, it can be appropriate to weight the data in the sample so that it better reflects the target population.
Under Weighting, choose which background variables you want to weight the material against. It is most common to weight based on gender, age group and geographical area. But you have the option of weighting the material based on all the background questions you asked where you have information about the target population.
