Collection of Statistical Data on Single Vehicle Incidents Robust. GRD1-2002-70021 Method of Approach and Work 1 completed Presented by Gavin Williams, TRL, UK

APPROACH APPROACH APPROACH APPROACH • Scoping study distributed in early April 2004 • Replies received from: – Norwegian Public Roads Administration (NPRA), Robust. GRD1-2002-70021 Norway – Politechnico di Milano, Italy – Autostrade, Italy 2 – Centre for Automotive Research and Development (CIDAUT), Spain – European Union Road Federation (ERF), Belgium – Volkmann & Rossbach Gmbh & Co., Germany

APPROACH APPROACH APPROACH APPROACH • Two documents were distributed in early May 2004 for the collection of incident data: – A Table (for completion) – Guidance for completing the Table (for continuity) Robust. GRD1-2002-70021 • Coding used to aid analysis • Different driving legislation 3 Incident data for: • • Single vehicle incidents • Incidents on ALL roads • Incidents in which a VRS has been hit • Only incidents FROM 1st Jan 1990

DATA COLLECTION TABLE DATA COLLECTION TABLE DATA COLLECTION TABLE DATA COLLECTION TABLE • General incident information (date, road type, speed limit) • Details of the vehicle (make, model, weight) • Movement and damage to the Robust. GRD1-2002-70021 vehicle • Severity and location of injury to the occupant(s) 4 • Type of VRS • Impact speed and angle • Data source(s)

RESULTS RESULTS RESULTS RESULTS • TWO main contributions: – TRL TRL TRL TRL (23,313 incidents - basic data, 1990-02) Robust. GRD1-2002-70021 – Politecnico di Milano Politecnico di Milano Politecnico di Milano Politecnico di Milano (70 incidents - very detailed data, 2000-03) 5 The results of the analysis and subsequent conclusions are therefore based only on the two sets of data provided from the UK and Italy

RECOMMENDATIONS RECOMMENDATIONS RECOMMENDATIONS RECOMMENDATIONS • For all impact testing with cars, an impact speed of 110kph is recommended for all testing; • The impact angle for cars remains at twenty degrees; Robust. GRD1-2002-70021 • The number of registered motorcycles be recorded, and the occurrence of such incidents analysed in future years; 18 • It is recommended that the weight specified for the small car test (currently referred to as TB11) should be changed so as to be 950±50kg;

RECOMMENDATIONS RECOMMENDATIONS RECOMMENDATIONS RECOMMENDATIONS • It is recommended that the vehicles used for the testing of VRS are no more than 5 years old; • The data have shown that one dummy (either instrumented or un-instrumented) should be seated in the vehicle during all testing between cars and VRS; Robust. GRD1-2002-70021 • It is further recommended that the dummy should be placed on the driver’s side of the vehicle; 19 • It is recommended that, any dummy installed in a vehicle during VRS testing should be restrained by a seat belt.

RECOMMENDATIONS RECOMMENDATIONS RECOMMENDATIONS RECOMMENDATIONS • An additional task has examined incidents occurring on UK roads; • It has been found that there is little information currently collected regarding Robust. GRD1-2002-70021 the VRS at incident scenes; • It is recommended that this information is 20 collected to aid future analysis and research.
