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)

Coding used to aid analysis
Different driving legislation
Incident data for:
Single vehicle incidents
Incidents on ALL roads
Incidents in which a VRS has been hit
Only incidents FROM 1st Jan 1990

TWO main contributions:

– TRL TRL TRL TRL

(23,313 incidents - basic data, 1990-02)

– Politecnico di Milano Politecnico di Milano Politecnico di Milano Politecnico di Milano

(70 incidents - very detailed data, 2000-03)

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;

The number of registered motorcycles be

recorded, and the occurrence of such incidents analysed in future years;

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;

It is further recommended that the dummy

should be placed on the driver’s side of the vehicle;

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
ccurring on UK roads;
It has been found that there is little

information currently collected regarding the VRS at incident scenes;

It is recommended that this information is
