Long Distance Double Road Train and Triple Road Train Combinations
Source publication
The Australian Road Transport Industry has undergone significant changes over the last 30 years. There have been three reviews and increases in the mass carrying limits of trucks. These occurred in the mid 1970s, the Economic Review of Vehicle Limits (ERVL), in the mid 1980s, the Review of Road Vehicle Limits (RoRVL) was undertaken, and the mid to...

... the road train which was very much restricted to the remote and country highway regions, (See Figure 1) even up to distances of a hundred kilometres or so from the major cities, the usual B-Double configurations (See Figure 2) all very much operate on both long distance routes as well as within the major urban arterial networks within all capital cities. The smaller 19 metre mini-B-Double, not listed in Figure 2, has general access in all capital cities and can operate at the same Gross Vehicle Mass Limits as its big brother the 25 meter B- Double. ...

Aim
The aim of this paper is to present an optimization proposal in the automated guided vehicles design used in hospital logistics, as well as to analyze the impact of its implementation in a real environment.
Method
This proposal is based on the design of those elements that would allow the vehicles to deliver an extra cart by the towing method....

City is the place of the largest concentration of economic and social activities, and the delivery of goods is a prerequisite for the maintenance of urban life and business activities for achieving wealth and development of the city. Logistics systems and processes that enable the realization of commodity flows support employment and generate income, but may also have negative impacts on all essential functions of the city. Therefore, logistics plays an important role in the competitiveness of urban areas and should be an integral part of the city's economy. From the perspective of sustainable development, i.e. social, environmental and economic efficiency, logistics processes primarily urban freight transport, are far from optimal. The growth of road freight transport and traffic congestion, air pollution and other negative impacts on the environment, inefficient use of land and the rising costs of delivery of goods affect the definition and exploration of different initiatives of city logistics. This paper describes the initiatives that do not require large infrastructure investments and do not change the existing urban context, but can improve its sustainability.

This paper develops a framework for evaluating urban freight transport sustainability initiatives. The purpose of the framework is to identify basic dimensions and classifications for urban freight transport, to structure the urban freight transport field, and to identify critical success factors and barriers for successful urban freight transport sustainability initiatives. Based on a selective literature review in section 2, we develop the basic framework in section 3. We distinguish three phases that affect the results of an urban freight transport sustainability initiative: the design, the execution, and the evaluation. In the next section we provide classifications for all eight framework's basic dimensions, which together form the complete framework. In the final sections of this paper we divide the initiatives in twelve different initiative types to structure the urban freight transport field.
