Progress on participant recruitment

Main research areas
• Crash causation and risk • Everyday driving • Distraction and inattention • Pedestrians and cyclists • Motorcycle behaviour • Eco-driving
![Page 21: Nicole van Nes (SWOV) Project Coordinator](https://reader031.vdocuments.us/reader031/viewer/2022020623/61ef08c268999c524f0dd77e/html5/thumbnails/21.jpg)
Crash causation and risks • Crash causation (“holistic”)
– How can contributing-factor chain schemas be applied to naturalistic road user data?
– What are the factors that contribute to the occurrence of safety critical events for lead- vehicle and intersection conflict scenarios for cars and trucks?
– Are there driver/vehicle/environment factors that frequently occur together in a safety critical events?
• Risk calculation – What are the risks of different driver behaviours? – Is there a difference in the driving related risks when stratified by road
type, vehicle type and country? – What is the risk of disregarding safety precautions?
![Page 22: Nicole van Nes (SWOV) Project Coordinator](https://reader031.vdocuments.us/reader031/viewer/2022020623/61ef08c268999c524f0dd77e/html5/thumbnails/22.jpg)
Everyday driving Descriptive analysis of everyday driving • To what extent are driver factors associated with risky
behavior? • To what extent are environmental factors associated with
risky behavior? • To what extent are driver assistance systems used? • To what extent are seatbelts used? • How does traffic culture influence driving behavior?
![Page 23: Nicole van Nes (SWOV) Project Coordinator](https://reader031.vdocuments.us/reader031/viewer/2022020623/61ef08c268999c524f0dd77e/html5/thumbnails/23.jpg)
Distraction and inattention • Attention selection mechanisms
– Which perceptual cues reliably capture attention and trigger avoidance maneuvers in SCEs?
– Why do the reactive attention capture mechanisms, identified in RQ1, sometimes fail and lead to crashes?
– What factors determine how drivers proactively allocate their attention in anticipation of how a driving situation will unfold and why do these proactive selection mechanisms sometimes fail?
• Involvement in secondary tasks – What are the key factors influencing the willingness of drivers to deliberately
engage in secondary tasks such as phone conversation, dialing or texting? – How do drivers adapt ongoing secondary task activities to the evolving
driving situation? – To what extent can an individual’s willingness to engage in secondary tasks,
and its effects on risk and driving performance, be predicted from psychological tests?
![Page 24: Nicole van Nes (SWOV) Project Coordinator](https://reader031.vdocuments.us/reader031/viewer/2022020623/61ef08c268999c524f0dd77e/html5/thumbnails/24.jpg)
Pedestrians and cyclists • Drivers interacting with cyclists and pedestrians
– What characterizes Safety Critical events (SCE) involving motorized traffic and cyclists/pedestrians at intersections?
– How do car drivers behave at intersections in urban areas where they might encounter cyclists/pedestrians (in normal conditions, not SCE).
– Which ‘external’ factors (e.g., intersection design) modify those behaviours?
• Are the VRU related SCE’s identified by the Mobile Eye system (warnings) correct, relevant, reliable and properly timed?
![Page 25: Nicole van Nes (SWOV) Project Coordinator](https://reader031.vdocuments.us/reader031/viewer/2022020623/61ef08c268999c524f0dd77e/html5/thumbnails/25.jpg)
Motorcycle behaviour
• PTWs behavior (based on riding data) – What characterizes Safety Critical events (SCE) involving PTWs? – Which circumstances (rider, infrastructure, trip) have impact to
SCE occurrence? – What is riders speed choice in relation to the speed limit and the
situation? – What characterizes looking behavior of PTW riders in left turn
maneuvers?
• Behavior towards PTWs (based on driving data) – What is the role of timely perception of a rider by drivers?
(conspicuity)

Eco-driving • Effects of driving styles on eco driving
– Does the vehicle power-to-mass ratio affect the driving style? – How much do drivers deviate from the speed limit in free flow situations,
and why? – Is eco-driving and safe driving correlated, through increased anticipation
of road infrastructure and traffic situations?
• Potential effect of eco-driving – When do drivers brake and is it necessary to brake in each instance? – Is eco-driving a visible characteristic of certain drivers? – Do drivers shift gear to avoid high engine speeds and high fuel
consumption?

Data Sharing and Data Protection Concept
• Data available for post project research
• Data access for non-partners
![Page 32: Nicole van Nes (SWOV) Project Coordinator](https://reader031.vdocuments.us/reader031/viewer/2022020623/61ef08c268999c524f0dd77e/html5/thumbnails/32.jpg)
Remote access to UDRIVE data • Analysis performed remotely on the
common dataset
• Central Data Center (CDC) • located at SAFER • Hosts all data
• Local Data Centers (LDC) • located at DLR, Volvo and CEESAR • Hosts part of data
• Partner Data Center (PDC) • Partner can download data and
become PDC
![Page 33: Nicole van Nes (SWOV) Project Coordinator](https://reader031.vdocuments.us/reader031/viewer/2022020623/61ef08c268999c524f0dd77e/html5/thumbnails/33.jpg)
Post-project access to UDRIVE data Infrastructure for remote access and data protection • Third parties can remotely access all
data from CDC, except Personal Identity Data (PID)
• PID (video, GPS) is only accessible at the premises of CDC or PDC
• Third parties must apply to analyze data and adhere to the Data Protection Concept
• All data remains in original storage. Data for publications can be extracted based on consent from drivers

Concept Obstacles • Funding for post-project data storage and access not
yet solved • Data protection of PID (necessary!)
