Update on Naturalistic Driving studies in The Netherlands and Europe Fifth Safety Research Symposium Second Strategic Hichway Research Program (SHRP 2)

1 Update on Naturalistic Driving studies in The Netherlands and Europe Fifth Safety Research Symposium Second Strategic Hichway Research Program (SHRP 2) Transport Research Board July 13-14, 2010 Divera Twisk, Nicole van Nes, Michiel Christoph, Rob Eenink July, Washington DC Safety Research Symposium (SHRP 2) TRB

2 Prologue, DaCoTA & Interaction Objective PROLOGUE DaCoTA Interaction In depthunderstanding Normal driving Pre-crash behavior Monitor SPI s to study safety trends for all European countries Speed Safety belt use etc Study effect of use of in-car devices Sample Variables/ observation Technology Duration

3 Relation to other European ND projects level of sophistication of data gathering PROLOGUE DaCoTA INTERACTION Sample size

4 Prologue Promoting real Life Observations for Gaining Understanding of road user behaviour in Europe

5 10 partners SWOV coordinator: Rob Eenink

6 Objectives of PROLOGUE Prologue: outlines for a large European ND study Feasibility of a large ND study in Europe (objective 1) Broad support stakeholders (objective 2)

7 The study in relation to the two objectives Objective 1: assessing feasibility Objective 2: gaining support for large scale study

8 Aims of field trials (objective 1) 1. To define recommendations on: methodology technology, implementation data management 2. Hands-on experience of the potential usefulness of these data to the study of various research questions. 3. Exploration of technologies In-vehicle technology versus out-of-vehicle technology Limited versus extended equipment Technology that monitors only vehicle behaviour versus technology that monitors also the environment

9 5 Small scaled field trials (Coordinator Or Yarok) Israel: Novice drivers: exposure & risky conditions at different levels of experience Austria: Novice drivers: risk indicators and effect of feedback Netherlands: Vulnerable road users: in car versus on-site observations Spain: Safety assessment of use of nomadic devices Greece: Assessment long term effects of FCW and LDW (off/on)

10 The Dutch Field Trial Focus on: vulnerable road users particular cyclists Research: Michiel Christoph Nicole van Nes

11 Typically Dutch!

12 Cyclist crashes 180 fatalities and 7000 hospitalizations per year 58 % of casualties a motor vehicle involved 79% of casualties in Urban areas: 67% on intersections Serious injuries are on the increase

13 The Dutch field trial: on-site & in-car To study the interaction between car drivers and vulnerable road users What does the driver look at? (in- vehicle observation) Is that influenced by: The presence or absence of vulnerable road users? (site-based observation) Whether he crosses on the fly (green) or after stand-still Results will be analyzed as: Between driver comparisons on the study intersection (sitebased observation/ between drivers) Within study driver comparisons on different intersections (in- vehicle observation)

14 Two complementary observation methods? In-vehicle observations over several intersections Site-based observations Cases with complementary data from both observations

15 Variables Focus on behavior at (signalized) Intersections Speed (approach speed, crossing speed) Interaction between different road users In-vehicle measures Speed Acceleration (g-forces) GPS 2 camera s one at the face of the driver, one outside forward view

17 Materials observation equipment Triggered based Video of driver & forward view (no sound) Predefined locations Extreme events (speed/braking) GPS location GPS Speed Accelerations in 3-axis

18 Summary Three projects with different objectives Next year we will be able to present data Issues for further discussion Integration with environmental issues (e.g. eco-driving behavior) and traffic management) need to considered International cooperation is needed, but how to organize this with advantages for all partners?

The broader scope: monitoring behaviour by ND and other types of study
