“…Additionally, multiple other indicators related to energy efficiency are also frequently used as alternatives, such as energy intensity (energy consumption required for a unit of transport volume), fuel consumption rate (FCR, fuel consumption per unit of transport volume), CO 2 emissions rate (CER, CO 2 emissions per unit of transport volume), etc. [29,30]. The units used to measure transport volume and energy consumption are also quite diversified.…”

Abstract:Energy efficiency is one of the key factors affecting energy consumption and greenhouse gas (GHG) emissions. By focusing on China's transport sector, this study comprehensively reviews and compares the energy efficiency performance of passenger vehicles, light-duty commercial vehicles, commercial road transport, commercial water transport, aviation transport and railway transport, and identifies the opportunities for further energy efficiency improvements. It is found that railway transport exhibited the greatest improvement in energy efficiency during the past decade, which was mainly driven by progress in its electrification. Passenger vehicles have also experienced considerable energy efficiency improvements, which can be mainly attributed to the establishment of mandatory fuel consumption standards. In contrast, commercial road transport has shown the least improvement, due to insufficient policy implementations. Based on the analysis, it is recommended that, as China's present policy framework to improve energy efficiency in the transport sector is generally effective, it should be consistently maintained and successively improved. Electrification represents a major opportunity for improvement of energy efficiency in the transport sector. Such potential should be fully tapped for all transport modes. Greater effort should be put into improving the energy efficiency of commercial road transport. The policy instruments utilized to improve the energy efficiency of heavy-duty vehicles should be as intensive and effective as the policy instruments for passenger vehicles.

Urban mobility is highly dependent on private vehicles causing pollution, traffic congestion and traffic accidents. The tram has become one of the most relevant public transport modes in those cities which need to reduce the private vehicle dependency. However, the implementation of this kind of infrastructure must be done carefully to avoid unsuccessful route designs which make the system unfeasible to operate. With the aim of analysing the impact that a tram can cause in a city, an original methodology has been developed, which takes into account the effect of the new transport system implementation on three subimpacts: traffic, public bus and outskirts neighbourhoods. This methodology uses different data sources from urban traffic, environmental and energy systems. The methodology has been applied to the city of Zaragoza (Spain) with a current population of around 700,000 inhabitants. The main results found were that tram line 1 saves 6% of the annual final energy consumption of urban mobility, urban traffic has decreased by 7.7% in the city as a whole and by 39.7% for streets close to the tramway.

“…A study in 2013 investigated the effective factors on determining of number and types of required cars for companies [76] and in the same year, possible models also developed for this purpose which estimate the number of required vehicles with regard to requirement of customers, operational costs and availability of vehicles [79,81,83]. As the target function in transportation modeling is multi-criterion, many researchers have been used the idealistic programming method [77][78][79][80][81][82][83][84][85].…”

Abstract-Transportation is one the most important pillars of economic growth and development. However, due to geographical and economical conditions, flexibility of road transportation and presence of sufficient infrastructures, the road transportation is one of critical importance in Australia. Vehicles are one part of road transportation and hence, evaluating the capacity of road transportation system or vehicles is very crucial in transportation programming. In the current research, a model is presented for determining the demand to different types of vehicles in various states of Australia. Since a multi-criterion capacity evaluating program has been considered, the idealistic programming method is used in modeling. Due to the nature of the problem, zero and one variables are introduced to the model which, in turn, caused to transform the model to a non-linear complex rational number programming problem. As solving such types of problems is difficult, especially for large values, an innovative method, regarding the structure of the problem, is presented to transform the non-linear problem to a linear one. Moreover, this study is performed for various conditions such as increase of container transportation.
