SHANTI – Cost Action n° TU0804 "Survey Harmonisation with New Technologies Improvement"
Chair: Jimmy Armoogum
Start of Action: April 2009 - End of Action: April 2013
The main objective of the Action is to provide guidelines for harmonizing national travel surveys across Europe. This harmonization aims at improving their comparability without preventing longitudinal analyses with previous surveys at country level and therefore should increase data quality at national level. The Action will build bridges between European countries as well as among researchers, enhancing research and disseminating recommendations throughout European society. More specifically, the Action will (i) bring together researchers from different European countries, tackle the data needs and stimulate the network by training junior researchers, and (ii) bridge the gap between academia and society by taking societal needs into account, and link researchers and practitioners via the provision of practical recommendations and sharing experiences and best practice. The concrete outcomes of this Action will be twofold : on one hand, concrete harmonization guidelines (related to protocol, questionnaire design, variables definition, etc) will be built from the field skills coming from researchers involved in NTSs and therefore aware of the needs for continuity with previous surveys in each country; on the other hand, these skills and guidelines will be disseminated to countries, especially New EU Member States, where national travel surveys are still to be set up so that these new surveys rely on commonly agreed best practices.

Working Group 1: Methods and tools
This Working Group should tackle statistical problems, which are methods and tools that can be used for passenger and vehicle surveys. From the work achieved in this WG, the Action will report all best practices for the different areas to be undertaken in survey methodologies (sampling, weighting, etc.). This WG will develop a generic methodology enabling the combination of multiple sources for transport and mobility related information (including, for example, conventional mobility surveys as well as new sources of data such as trace data from personal and vehicle tracking systems based on GPS, GSM and related technologies) in a coherent and statistically rigorous way.
Working Group 2 Use of new technologies
The massive reduction in the cost of GPS services, the general reduction in size, weight, energy consumption and price of various measurement devices (e.g. GSM, accelerometers, pulse meters, and others) and the improvements in battery power enable conducting continuous monitoring studies of a longer duration (several days, weeks). The respondents are relieved of the more time consuming aspects of such studies, but retain control over their participation. The disadvantage of such passive monitoring studies is the absence of information about the purpose and social context of the observed travel.
Working Group 3 Vehicle-based survey
On the European average more than 95 % of all passenger cars and half of all light commercial vehicles are permanently available to private households. These vehicles can be either company cars or privately owned. The profiles of vehicle use can be specified through average annual driven mileage per vehicle and for the fleet as a whole total, the purpose of travel as to the trip destination, the infrastructure use could be shared among urban, inter-urban or motorway road use, and fuel consumption could be measured together with e.g. data on CO2 emissions. Hence data collected on vehicles are also of great interest for a better knowledge of European mobility trends.
Working Group 4 Household travel surveys
Several COST Countries have established traditions in household transport surveys, which are often influenced by cultural, geographic and administrative backgrounds of the individual country. Often, these surveys have proven useful within the borders of the individual country, while on the other hand, there are comparability problems over the national borders due to differences in methodology, definitions and contents.
In WG 4, the state of the art of household surveys across Europe shall be determined – this shall mainly focus on transport surveys, but also on further data sources with important meta-information. Subsequently, it shall be analyzed how far these existing data sets are comparable and to what extent they could be merged into a continental data base. At the same time, it has to be discussed what kind of data is necessary for a sound transport policy and for transport models (e.g. variables on emissions, data to calibrate models).
Finally, guidelines and recommendations shall be discussed: How can future surveys be implemented to ensure continuity and usefulness in the individual countries on one hand and a higher level of harmonization on the other hand?
