M.Ing. (Transport Engineering)
The background to goods loading in South-Africa are briefly
discussed. Retail are classified and distinction are made between six
different retail types. Goods vehicles are also classified and a design
rigid and articulated goods vehicle (for retail) are determined. The
results of the surveys at retail outlets are discussed and the
characteristics of goods vehicle movement for example trip
generation rates, typical total loading times, service times and goods
vehicle composition at the different retail types are dealt with.
Regression curves has been calculated for goods vehicle arrivals
against trading area. Multiple channel queuing theory is used to
determine the loading space requirements for the different types of
retail. Theoretical methods .to describe the vehicle track and swept
paths during maneuvering is dealt with and turning circle templates
for the identified design vehicles are developed. Dimensions of a
typical loading area are determined using the templates. The
dimensions has also been verified with practical maneuvering tests
involving two rigid and two articulated goods vehicles. The
maneuvering tests showed that the driving (maneuvering) capabilities
of a driver are playing a major role in the loading area needed. The
basic principles involved when designing a loading dock are lastly
briefly discussed.
