CONTEXTUAL INFORMATION
-------------------

1. Abstract for the dataset - REQUIRED

Leading Pedestrian Intervals (LPIs) and Curb Extensions (CEs) are operational and geometric countermeasures that are designed to reduce pedestrian injuries and fatalities. While Oregon DOT implements both of these treatments, there is limited guidance on how to implement these options (separately or in combination with other treatments). The present research study aimed to fill gaps in existing knowledge to improve pedestrian safety at signalized intersections by developing enhanced guidance on when and where to implement LPIs either solely or in conjunction with complementary treatments such as CEs. The driving simulator data includes turning speed, approach speed, total fixation duration across four areas of interest (traffic signal, pedestrian signal, No Turn on Red (NTOR) sign, pedestrian), and survey data (pre-survey and post-survey).

2. Context of the research project that this dataset was collected for.

The dataset from the driving simulator portion was collected and assessed to study driver behavior (turning speed, approach speed, and total fixation duration) at 24 signalized intersection scenarios. This data was collected to supplement the field work data and to gain additional insights regarding LPIs and Curb Extensions.

3. Date of data collection:

2025-05-02 to 2025-06-11

4. Geographic location of data collection:

OSU Driving & Bicycling Simulator Laboratory in Corvallis, Oregon.

5. Funding sources that supported the collection of the data:

Oregon Department of Transportation (ODOT).

METHODOLOGICAL INFORMATION - REQUIRED
--------------------------

1. Description of methods used for collection/generation of data: 

Turning speeds and approach speeds were collected using the OSU Driving Simulator’s data acquisition system (SimObserver Pro). Total Fixation Duration (TFD) data was collected using Tobii Pro Glasses 3 and iMotions. Survey data was collected using Qualtrics XM. 

2. Methods for processing the data: 

Speed data was exported in .csv format from SimObserver Pro and Data Distillery by Realtime Technologies, these files were organized using Python, and descriptive statistics were generated using Pivot Tables in Microsoft Excel. The Total Fixation Duration (TFD) data was transcribed by defining 4 Areas of Interest (traffic signal, pedestrian signal, NTOR sign, and pedestrian) through the eye tracking glasses module of iMotions, this data was exported in .csv format and descriptive statistics were generated using Pivot Tables in Microsoft Excel. The survey data was exported in .csv format from Qualtrics and descriptive statistics were generated using Pivot Tables in Microsoft Excel. Finally, visualizations for all datasets were created using Microsoft Excel and PowerPoint. 

3. Instrument- or software-specific information needed to interpret the data:

SimObserver Pro, Data Distillery, iMotions, Microsoft Excel. 

4. Standards and calibration information, if appropriate:

For total fixation duration data, Tobii Pro Glasses 3 were calibrated for each participant by asking them to stand 2 feet away from a calibration card and focus their gaze on the center of the calibration target.

5. Environmental/experimental conditions:

Speed and total fixation data were collected during the driving simulator experiment (simulator room). Survey data was collected before and after the driving simulator experiment (operations room). 

6. Describe any quality-assurance procedures performed on the data:

All raw datasets were reviewed for any missing observations and quality checks were performed on all transcribed datasets. For the total fixation duration data, the lead graduate research assistant supervised and performed quality checks on the data transcribed by other graduate and undergraduate research assistants. 

7. People involved with sample collection, processing, analysis and/or submission:

David Hurwitz and Hisham Jashami provided support with the design, collection, and analysis of the driving simulator experiment. Elsa A. Moreno Rangel collected, transcribed, and generated visualizations of driving simulator experiment datasets. Hisham Jashami conducted statistical analysis of driving simulator experiment datasets. OSU graduate and undergraduate research assistants assisted with data collection (Syed Baqir UI Husnain, Jane Weber, Erika Anderson, Emilio Ronaldo Calderon, Emily Dahbura) and AOI data transcription in iMotions (Timila Marharjan, Louisa Wildman, Mahde Abusaleh, Charles Tuckfield, Clarence Fernado).
