The objective of this deliverable was to provide preliminary results from the analysis of mobility impacts from the TeleFOT project. Specifically, the objective was to discuss the concept of mobility, to validate the method proposed for mobility impact assessment and to pilot the mobility research questions. Mobility is concluded to be the willingness to move along with potential and realized movement rather than just physical movement of vehicles, people and goods. Along with transport and infrastructure it encompasses people’s and road users’ attitudes, opinions and choices in their daily travelling and movement. The concept of mobility is versatile. However, it is often reduced to transport or confused with accessibility or efficiency. In TeleFOT, a travel diary was developed to meet the information needs in order to address research questions and hypotheses related to mobility impact assessment. Diaries are collected once in the before-phase of the FOT and two or three times in the after-phase depending on the length of the FOT. A supplement to the travel diary is filled in during the after-phase travel diary data collection periods to collect essential information about major changes in the mobility needs and possibilities of the test users and their families due to factors other than TeleFOT functions. Trips reported in the travel diary were compared to logged trips. Travel diaries were returned by 73% of test participants. In general the travel diaries were filled diligently by users, with 96% of travel diaries returned fully completed. However, only 67% of all trips either reported in the travel diary or logged were found in both data sets. Forty-one percent of trips reported in the travel diary were missing the corresponding logger data. Eight percent of logged trips were missing the corresponding travel diary entry. An alarmingly high (18%) proportion of the logged data was trips that were fragmented into several trips in the logger data. The pilot analyses of the research questions indicated no problems for the final analysis. All research questions concern a change in something. The change itself could not be analysed based on the first data sets available for the pilots. However, it was confirmed that most of the variables needed could be obtained from the data. The analysis of route choice could not be piloted yet, as map matching was not complete. In addition, a question related to user uncertainty was added to the post-test questionnaires. The preliminary results show no high expectations among the test participants. In conclusion, the mobility impacts of TeleFOT functions should possible to analyse for the final results as planned. More specific instructions were given for the final analysis. (Author/publisher) For more information on this project, see http://www.transport-research.info/web/projects/project_details.cfm?id=…
