Naturalistic Riding Study - 2besafe

VIEWS: 18 PAGES: 21

Call in fitness, people are stepped out of the outdoors. Some friends on the weekend ride to the suburbs is a good idea. Despite the recent weather is not suitable for the sport, but look at the whole year, you can see the team through the ride to the gym in the growth, the mall's folding bikes are out of stock. Period of time to do a long trip, the overall quality of the body is a test, muscle strength, bone flexibility, ligament flexibility have been improved. Cycling during exercise is not small, if sustained, speed, heart rate can reach 150 beats / minute to 180 beats / min, to enhance people's heart and lung function. Rising degree of concern.

The purpose of the Naturalistic Riding Study



What history and previous
research tells us……..

 Behavioural, ergonomic or human
factors issues appear to be a major
contributing factor to PTW accidents

 Poor or incorrect collision-avoidance
strategies are a significant factor in
crashes

WP 2.3 – How we see the research….



                                          No study of real-world motorcycle
                                          riding behaviour has previously
                                          been published

                                          Unique opportunity to develop
                                          understanding of key rider - and
                                          other road user – behaviours

                                          Potential to record accurately the
                                          collision-avoidance measures
                                          used by riders in crashes or near-
                                          crash situations




         Brussels Meeting, 29 June 2010                                        4
 Choice of study method

Review of previous studies to draw information from:
   o100-car naturalistic driving study (USA)
   oField Operational Test Support Action (FESTA) project
   oTest Site Sweden Field Operational Test

Core requirements determining method:
   oNaturalistic
   oNot unnecessarily risky
       oRiders must have directly relevant experience of bike similar to test bike
       oExcessively risky riders eliminated

   oRepeatable in four different countries
       oClear ethical boundaries
       oUsing proven technical equipment and processes




             Brussels Meeting, 29 June 2010                                          5
 Developing a methodology for a bike study

This is an ‘exploratory’ research activity…….


                                             Key differences
                                             Reduced size
                                             Additional axis of
                                             movement
                                             Rider exposure
                                             Reduced security




                    Unique challenges
                        Ensuring sensors are installed discreetly
                        Maintaining the handling characteristics
                        Maintaining crash-safety

The purpose of the Naturalistic Riding Study


To produce fundamental knowledge of PTW rider behaviour,
performance and safety


Understand the implications of riding alone and when
interacting with other road users


Inform and develop a broad and integrated package of
countermeasures/public policies for improving the safety of
PTW riders in Europe.
