A STUDY OF THE ECONOMICS OF ROAD VEHICLE LIMITS; REPORT ON OVERSEAS MISSION

The purpose of discussions overseas was (a) to consider the study's recommendations in the light of overseas practice and experience in the application and interpretation of the regulations to axle types and vehicle configurations; (b) to identify the areas of current work and research in relation to particular issues associated with mass and dimension limits for road vehicles; (C) to make a general assessment of the trend in the use of heavy vehicle configurations and axle types. The countries visited included Mexico, Canada, United States, England and Europe, in addition to an earlier visit to New Zealand. Considerable variations exist in regard to axle limits and gross vehicle loading. The study's recommendations imposed the need for generalised "load equalisations" requirements on axle groups. Future moneases in limits may be related to specific aspects of suspension system, whereby differential higher limits may be dependent on the promotion of design features aimed at minimising the dynamic component of axle loading.
