MEILI Travel Diary

The MEILI Travel Diary is an open-source highly modular system for the collection and annotation of travel diaries of multiple users. The system contains two main components: the Mobility Collector, which was presented at the Mobile Ghent 2013 conference, and the Web Diary, which was presented at the the Mobile Tartu 2016 conference.

Project status: Ongoing


SPOT 2 investigates how the data collected during the SPOT 1 project can be used. Some of the topics of interest are the following:
1. The stability and variability of individuals’ day-to-day choices. This includes analysing the tendency and degree of variability and stability of their chosen travel modes, activity locations, individual’s time allocations and trip chaining behaviours, across different groups of travellers.
2. The comparability of standard transport model indicators and assumptions with GPS based observations. This includes comparing the individual’s revealed multimodal and route choices with hypothetical shortest path and multimodal assumptions which are commonly used in urban transport modelling.
3. Exploring space-time accessibility factors that shape and influence individual travel decisions. The individual activity-travel pattern that was collected from the survey is a result from trade-off between individual’s travel needs and constraints.

SPOT Gothenburg

SPOT Gothenburg studies the feasibility of using the MEILI system in a new and untested region (Gothenburg, Sweden) with the end goal of collecting how a small sample of users (around 40) travels for a week.

Project status: Project successfully completed (January, 2017).


SPOT 1 studies if an application installed on a smartphone equipped with GPS can be used to replacement or supplement a traditional travel diary. The advantages and disadvantages of traditional travel diaries as well as the new method are discussed compared. The methods are implemented in the same city, at the same time and with the same respondents using both methods to facilitate the comparison.

Project status: Project successfully completed (January, 2016).

Space Time Alarm Clock

Space Time Alarm Clock (STAC) is an Android application designed to help you get to a destination in time with minimal interaction. It does so by continuously 1) identifying possible moves from your current location, 2) showing, for each move, how long it will take to reach the destination if it is taken, and 3) alerting when no move will lead you to the destination in time.

Project status: Project successfully completed (June, 2014).

Open Science Map

OpenScienceMap provides free and open maps for Android with the fastest and 100% pure vector maps around. It is a platform used to enable researchers to implement their ideas, to cooperate with others, and to share their results with everybody.

Project status: I was hired as a research intern working on the project in June-September 2013 during my thesis. The Open Science Map project is ongoing.
