SNIP measures contextual citation impact by weighting citations based on the total number of citations in a subject field.
SJR is a prestige metric based on the idea that not all citations are the same. SJR uses a similar algorithm as the Google page rank; it provides a quantitative and a qualitative measure of the journal’s impact.
The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years.

To calculate the five year Impact Factor, citations are counted in 2014 to the previous five years and divided by the source items published in the previous five years.

The Journal of Transport Geography is a leading interdisciplinary journal focusing on the geographical dimensions of transport, travel and mobility. It is international in its outlook, and welcomes both conceptual papers and theoretically-informed, empirically-oriented contributions on the movement of people, goods and/or information by any mode and at every geographical scale.
An indicative list of topics that are of interest to the journal includes:
•The spatial dimensions of sustainable and safe mobility and the interrelations of transport with energy, the environment and climate change
•The role of transport and mobility in the globalisation of economies and trade, and in political, cultural and other forms of spatial integration and change
• The spatial dynamics of aviation, high-speed and urban rail, maritime and intermodal transport, and logistics networks
•The linkages between transport infrastructure nodes, such as ports, airports, train stations, distribution centres and other terminals, and their local regional and national environments
•The effects of transport policy and governance on regions and places, both urban and rural
•The geographical dimensions of the organisation, structure and operation of public, private and other forms of transport provision
•The impacts of transport infrastructure investment on mobility, livelihoods, social networks, the spatial economy, and patterns of development
•The relationships of transport, travel behaviour and accessibility with the built environment in cities, urban systems, and in rural settings
•The relationships of age, gender, race/ethnicity and social class with travel, mobility and accessibility
•The geographical aspects of travel undertaken in the context of recreation and tourism
•The spatial implications of technological advances for mobility and transport systems
•Methodological developments highlighting the geographical dimensions of transport and mobility
•Geo-spatial methods (including GIS), digital data and qualitative methodologies for analysing issues in transport geography
