Abstract [en]

To better understand the interactions between physical built environment conditions and one’s well-being, we created a passive data collector for travellers and made the first step towards an explanatory model based on psychophysiological relations. By measuring biometric information from select trial participants we showed how different controlled factors are affecting the heart rate of the participants. A regression model with the impact factors such as speed, location, time and activity (accelerometer data) reveals how the factors relate to each other and how they correlate with the recorded individual’s heart rates throughout the observed period. For examples, the results show that the increase in movement speed is not linearly correlated with the heart rate. One’s heart rate would increase significantly when the individual reaches brisk walking and running speed, but not before nor after. Early morning and early evening time slots were the time where the observed individuals have the highest heart rates, which may correlate to individuals’ commute activities. Heart rates at the office would be lower than at home, which might correlate to more physical activities in the household.

Abstract [en]

As the world enters the intelligence age, it is no surprise that it is easier than ever to collect a vast variation of data types, whether it be raw data on human behaviour or processed data on travel patterns, that can be analysed with the help of artificial intelligence and prove to be incredibly valuable. In the domain of transport science, there is a constant quest to make the transport sector safer and more efficient without hindering those travelling from getting to where they need to be, when they need to be there, and data is vital in that quest.

The data collection tools that have become available in the fields of human-computer interaction and human-machine interaction over the past couple of years show great potential in uncovering how road users are affected by the surroundings they travel through or operate in. It is not only possible to meticulously collect how a person is interacting with a vehicle, be it a conventional or a remotely controlled vehicle, but it is also possible to collect biometric data to understand the psychological and physiological effects of the surroundings on the person. Such biometric data mostly stem from brain and heart activity, hence the title of this thesis: Put your heart into it.

This thesis explores how biometric and behavioural data can be collected, which methods should be used for analysis, and how experiments should be designed to optimize the potential of the data sets collected. Through three studies, focusing each on pedestrians, electric scooters, and general driver information searching, this thesis is intended as a first step towards a guide for other subdomains within transport, like psychology and engineering, on how to collect and analyse psychological information through physical data, also called psychophysiology.

The first study focuses on longitudinal studies with low-frequency biometric data collected through smartwatches. Providing cruder results in terms of psychological analysis but proving rather non-intrusive since the participants can turn on and turn off the data collection at their own will.

The second study utilises high-frequency biometric data, collected through chest straps and electrode helmets. The results provide more accurate readings, leading to analyses that provide more in-depth information regarding how a person’s cognitive load and risk perception is affected by their surroundings and their own actions.

The last study compares the biometric and behavioural characteristics of searching for information in both static and dynamic scenarios. Using eye-tracking and head-movement, this study uses simple data analyses to show how important eye-tracking can be when the aim is to understand what a road user is looking at when trying to search for information, whether they are static or moving along a road.

In conclusion, these studies and this thesis have not only proven how useful and efficient these data collection methods can be, but also taken early steps to uncover how to create studies that allow for these data collection methods to be trialled with the aim to understand how road users are affected in the current transport environment.

Abstract [sv]

När världen går in intelligensåldern är det ingen överraskning att det är enklare än någonsin att samla in en så stor variation av datatyper, vare sig det är rådata om mänskligt beteende eller om bearbetade data om resmönster, analyserad med hjälp av artificiell intelligens, kan denna data visa sig vara otroligt värdefull.

De datainsamlingsverktyg som har blivit tillgängliga inom områdena människa-datorinteraktion och människa-maskininteraktion under de senaste åren visar stor potential för att avslöja hur trafikanter påverkas av omgivningen de färdas genom eller verkar i. Det är inte bara möjligt att noggrant samla in hur en person interagerar med ett fordon, vare sig det är ett konventionellt eller ett fjärrstyrt fordon, utan det är också möjligt att förstå psykologisk och fysiologisk effekt av fordonets omgivning på personen. Sådana biometriska data härrör mest från hjärn- och hjärtaktivitet, därav titeln på denna avhandling: Put your heart into it.

Denna avhandling utforskar hur biometrisk och beteendedata kan samlas in, vilka metoder som bör användas för analys och hur experiment bör utformas för att optimera potentialen hos den insamlade datan. Genom tre studier, var och en med fokus på fotgängare, elsparkcyklar och allmän informationssökning för förare, är denna avhandling tänkt som ett första steg mot en guide för andra underdomäner inom transport, som psykologi och teknik, om hur man samlar in och analyserar psykologisk information genom fysiska data, även kallad psykofysiologi.

Den första studien fokuserar på longitudinella studier med lågfrekvent biometriska data insamlad genom smartklockor. Ger grövre resultat i termer av psykologisk analys men visar sig vara ganska icke-påträngande eftersom deltagarna kan slå på och stänga av datainsamlingen efter egen vilja.

Den andra studien använder högfrekvent biometriska data, insamlad genom bröstband och elektrodhjälmar. Resultaten ger mer exakta avläsningar, vilket leder till analyser som ger mer djupgående information om hur en persons kognitiva belastning och riskuppfattning påverkas av omgivningen och deras egna handlingar.

Den sista studien jämför de biometriska och beteendemässiga egenskaperna för att söka information i både statiska och dynamiska scenarier. Med hjälp av blickspårning och huvudrörelser, använder denna studie enkla dataanalyser för att visa hur viktigt blickspårning kan vara när syftet är att förstå vad en trafikant tittar på när de försöker söka information, oavsett om de är statiska eller rör sig längs en väg.

Sammanfattningsvis har dessa studier och denna avhandling inte bara bevisat hur användbara och effektiva dessa datainsamlingsmetoder kan vara, utan också tagit tidiga steg för att avslöja vad som fungerar och vad som inte fungerar när man skapar scenarier för studier med syfte att förstå hur trafikanter påverkas i den nuvarande transportmiljön.
