Developments in Denmark and looking ahead Taskforce on Road Freight Statistics, 2 nd meeting, January 28, 2016 Peter Ottosen
2
On-going development projects Mapping alternative business data sources Developing a mobile data collection application for smartphones/tablets 2
3
Mapping alternative data sources External consultancy doing the work Interviews with transport companies, industry associations, government bodies, providers of IT solutions for the transport sector, etc. Focusing on fleet management systems, GPS, tachograph and electronic consignment note Looking at availability, content coverage, legal issues, etc. 3
4
Preliminary results as of January 26 Interviews concluded to take stock of available data sources and their potential The most promissing solutions are integrated management systems that integrate fleet management systems and GPS and in some cases an order management system/electronic consignment note The cost in companies are insignificant when asking enterprises; high when asking industry associations Potential for investments in enterprises in new reporting methods is quite low No ”perfect” data source available – some assumptions and data manipulation/imputation must be done Have more than one tool in the toolbox 4
5
Main findings (in Danish) 5
6
Mobile application The main purpose is to ease the data collection for data providers The sampled unit is the vehicle and responsible data provider is the enterprise using the vehicle – the task of filling in the questionnaire is often delegated to the driver of the vehicle Moving away from paper questionnaires to web questionnaires only add a second work process in the enterprises where the filled paper templates need to be registered in the web questionnaire 6
7
Features Developed for iOS, Android and WP8 User interface developed first for Android – adjusted to iOS and WP8 afterwards Use built-in GPS for position Minimize data traffic – not required on-line access all the time Not tracking GPS all the time Only access to the App through Statistics Denmarks homepage Data uploaded to same database as web questionnaire One-way communication with sensitive data – challenge: change of driver 7
8
Current status of development The APP is currently in internal test External testers are being found – positive response External tests expected to be finished end February The App is expected to be up and running in March – ready for second quarter reporting 8
9
Presentation of the App Here some slides or a link will be added to show the App 9

Task force conclusions The road freight statistics in the basic model in the form most common i MS suffer from shortcomings To obtain higher quality, we need to augment or replace the basic data collection (cf. Austria, Sweden, Netherlands) Basically the problem lies in the quality of collected data – essentially concealed complete or partly missing data 10
11
Methodological approach Methods applied today Direct burden of proof (copy of tachograph – Austria) Extensive reductions in burden and use of assumptions and imputation (Simplified questionnaire – Netherlands) Use of business data (XML data from large enterprises – Netherlands) Ex post correction (Stand-still survey – Sweden) Future methods (within current legislation) Data collection (simplified?) using mobile technology 11
12
The output from the task force Detailed catalog of approaches including implementation descriptions Establish common imputation rules to use in simplified questionnaires (e.g. imputation of distance from origin and destination adresses) Methodology in case of mixed data collection (complete business data for some and survey among other) Other? 12
