4 Introduction Thousands of kilometers travelled per person per year Pedestrian Cyclist Public transport Car travel

5 GPS Devices Hand held device that tracks where people go in a given day A survey was sent to each person at the end of the day to ask the purpose of each trip and how they were travelling Advantages Easy to use Accurate Long battery life Disadvantages Person needs to remember to take the device Expensive to buy and send to different houses

6 Smartphone apps Smartphone app installed on participants phones The app tracks uses the GPS tracking function to record where people go on their allocated days Participants are sent a survey at the end of each day asking them purpose of each trip and how they travelled Advantages Cheap to carry out Disadvantages Low battery life Not always accurate

7 Online diaries People fill in a self-complete online diary of where they have gone the previous day People can see their trip on a map and make adjustments Advantages Significant cost savings Reasonably easy to use Disadvantages Can be difficult to untangle journeys with multiple trips High internet penetration

8 Length of the sample Current survey looks at 2 days New methods have the potential to survey 5 to 7 days Ability to reduce the sample without reducing the quality

9 Sampling Tested two methods of sampling Door to door SmileCity online panel

10 Trips per day Trips per day for different methods 7 Trips per day by method pilot survey and standard survey Higher trips per day can indicate higher quality for the method Initial inspection shows promising results gps device android app apple app online main respondent online other respondents Current survey Trip collection method

11 Different methods capture different trips Number of trips per day for car drivers and passengers Online methods good at capturing driving trips Wave Wave 2 Wave gps device online main respondent online other respondents Current survey Collection method

12 Different methods capture different trips Number of trips per day for pedestrians Online methods worse at capturing pedestrian trips Wave 1 Wave 2 Wave gps device online main respondent online other respondents Current survey Collection method

13 Different sampling and different trip numbers Trips per day by survey method and trip type Current travel survey Pilot - commercial panel Pilot - non commercial panel Commercial panel appears to have different characteristics to other sampled participants Car passenger or driver Pedestrian Public transport

14 Overall findings for the methods Smartphones The potential exists but the technology is not mature enough yet GPS devices Work well, but needs to be made cheaper for it to be viable Online diaries Potential to significantly reduce cost Recorded more trips than any other method low under-reporting Likely to be a secondary method if other methods are also used Length of survey People are willing to accept a longer survey length with different methods

15 Panel We retain people s contact details to construct a transport panel that allows us to cheaply push out transport related questions Questions can be pushed out to only a subset of people according to demographics or geography Significantly increases the transport information base Helps us amalgamate a number of different areas data collections
