Dataset for: Effects of Camera Height, Field of View, and Driver Age on Depth Judgement and Lane-Change Decisions in Camera Monitor Systems

## Experimental overview

A controlled laboratory experiment combining two aligned data collections was conducted using dynamic rearward driving scenarios in a Camera Monitor System (CMS) environment.

Participants completed:- a distance estimation task- a lane-change task

Experimental factors:- Field of View (FOV): 40°, 76°, 112°- Camera height: High / Low- Driver age: analysed using a median split at 31 years

## Data preprocessing

Preliminary analyses were conducted to examine the distribution of the dependent variables for the distance estimation (Dist) and lane-change (LSG) tasks. The LSG data did not show substantial skewness or kurtosis, whereas the Dist data contained several extreme values reflecting substantial underestimation relative to the actual target distances.

Outliers in the distance estimation data were identified using a threshold of ±2.5 standard deviations from the mean of the dependent variables (absolute and relative distance estimation errors).

Exclusion limits:- Absolute distance error: −84 m to 79 m- Relative distance error: −2.76 to 2.55

Two participants were excluded because more than half of their trials fell outside the ±2.5 SD range. Two additional participants contained isolated outlying trials (one and two trials, respectively); these isolated outlying trials were replaced using mean-value imputation within the corresponding dependent variable.

Following preprocessing, the final analysed sample consisted of 56 participants.

## Ethics and anonymisation

The shared datasets do not contain directly identifying personal information. Participant IDs are anonymised.

Raw interview recordings, interview transcripts, and any potentially identifying qualitative material are not included in the shared repository for ethical and privacy reasons.
