5. Mobility of Latvian population in 2017 Response rate – 61.2%
CATI – 19.6%
CAPI – 36.5%
CAWI – 5.1%
Why so low?
too short (two weeks and few days);
postal service delays (letter and reminder card);
is data input software/ CAWI user-friendly?
Good experience
Very few English CAWI questionnaires were filled in.
Key factor – well-trained interviewers!
Average length of interview – 30 minutes;
Interviewer can facilitate form completion and improve quality of collected data – by suggesting addresses, distances using Google Maps etc.

17. Implementation of guidelines Data validation steps
1st validation step – conversion of addresses to address codes, harmonization of purposes for outbound and inbound trips, other incoherencies
(around 5000 corrections submitted – time- and personnel-consuming activity);
2nd validation step – correction/ comparison of distances with GPS coordinates, imputation of distances travelled by public transport
(almost the same amount of corrections submitted).

Purpose of the trip;
Mode of transport for a stage (min, km);
Vehicle occupancy;
Type of petrol used by passenger cars.
Reasons for not making trips;
Distance (min, km) walked during the 1st stage (<>100 m);

Reasons for using passenger car, taxi, motorcycle;
Waiting time;
Address of the origin and destination;
Duration of the trip (departure, arrival).

20. Implementation of guidelines Variables – address of origin and destination
State Address Register;
Challenge – «manual analysis» of each trip and conversion of non-structured textual information into an address code;
Solution – use of classification of addresses and objects and/or Google Maps?

21. Implementation of guidelines Variables – foot as first and final stage of the trip
Sometimes respondents are confused about the routing for this question;
Results – starting/ final stage of the trip in ~11% of trips is longer than 100 m (0.6 km on average taking 9 min).

22. Implementation of guidelines Variables – Urban Audit (Eurostat)
Good comparison with other European countries and other variables from Mobility Statistics;
Share of journeys to work made by car

25. Tourism Demand Survey:
Implementation of guidelines Variables – medium and long distance mobility
Variables in
Tourism Demand Survey:
Adjustments required:
source: Tourism Demand Survey (Regulation No 692/2011 of concerning European statistics on tourism);
addition of trip coordinates;
calculation of the distances;
calculation of mobility variables.
number of same-day trips around Latvia;
number of overnight trips around Latvia;
number of same-day trips abroad;
number of overnight trips abroad;
mode of transport (passenger car, bus and coach, train, aviation, waterways, cycling, walking and other);
travel purpose (professional or personal);
address of respondent;
CATTU (Classification of Administrative Territories and Territorial Units of the Republic of Latvia) of destination of trip;
number of persons in the trip (passenger cars);
country of destination of foreign trips.

Task Force on Passenger Mobility Statistics and Road Traffic 11/10/2018

26. Implementation of guidelines Variables – medium and long distance mobility
Possible quality improvements:
In respect to the foreign trips an additional variable to the country should be added – city (to get a more precise estimate of a distance travelled);
In respect to the passenger cars a variable – type of fuel – should be collected.

31. Mobility of Latvian population in 2017 Data analysis performed by Pricewaterhouse Coopers Latvia
2.51 – the highest number of trips per day is for escorting purpose (school, station, doctor…);
44 km – the average distance per day for passenger car users;
19% - sustainable transport (public tr., clean fuel cars, active modes, multi-modal tr.) passengerkilometres of total pkm per year;
70% - time economy and personal comfort were the dominating reasons for using passenger car in short trips;
In Riga, number of trips by foot = trips by car (year);
Bicycle trips are more prominent in Riga, compared to other places.

32. Conclusions/ recommendations View of data users and experts
Inclusion of country-specific leisure activities (atypical distances in time);
Inclusion of loop trips in ponds, lakes (mainly fishing trips);
The minimum distance – 100 metres;
Distance not collected but imputed from the address coordinates.

Commercial mobility;
Waiting time (e.g. plane, private transport);
More detailed breakdown of trips abroad;
Mobile population abroad on the reference day;

It would be useful to have a repeated survey and have comparisons of data;
Publication of data (seminar, database), which variables?;
Smartphone functionality covers ~70% of the data collected within the survey; …

36. Mobility of Latvian population in 2017 Fun facts
Use of social networks:
CATI: address of a workplace of respondent is found on Facebook (shown publicly) because respondent refuses to say it during the interview (refuse to disclose private information);
CAWI corrections: destination country found on Facebook after respondent shared photos and check-ins with location information (long distance mobility trip half-completed).
Survey completion is not a problem also for famous people or high-level state officials;
Respondents typically forget to report trips when returning home (literally meaning, they stayed at work or shop overnight);
It is typical to report distances 2x longer than in reality.
