Project: HGV Blind Spot Modelling and Reconstruction Trial

Reference: S0819/V8

Last update: 25/09/2009 15:57:02

Objectives

The objectives of this project are to provide for large goods vehicles:
o Measurements of the ground plane field of view for the mandatory mirrors;
o Measurements of the ground plane field of view for 'badly adjusted' mandatory mirrors;
o Measurements of the ground plane field of view for the Fresnel lens;
o Measurements of the ground plane field of view for Dobli and BDS mirrors;
o A comparison of all ground plane field of view areas covered, including measurements;
o A comparison of the blind spots left and their relationship to vehicles in the adjacent lanes, including measurements;
o A summary of vehicle sizes that are likely to remain unseen, including measurements; and
o Suggestions for possible short / long term solutions.

Description

This study follows on from the original small trial covering a selection of target vehicle and goods vehicle sizes on visibly marked out motorway specification lanes, in relation to Directives 2003/97/EC and 71/127/EEC and for 5th, 50th and 95th percentile drivers.

The study should track target vehicles and other objects when covering the area from 5m behind to 5m in front of the drivers' eye line at 1m intervals and indicate clearly at what points the target vehicles appear / disappear from view in all variations.

Summary of results

  1. This research indicated that, even with supplementary devices in place, some potential blind spots still existed alongside the test vehicles which were large enough to hide a passenger car or vulnerable road user.
