The topics include accessibility to key services, the effects of technological change and the implications of road pricing.
CRC points out that people in rural areas travel around 10,000 miles each year compared with around 7,000 for all residents, and use of cars is significantly higher in rural areas.
Graham Russell, director of practice at the CRC, said: "With a continuing decline in local services, rural residents need to travel greater distances, and because of significant gaps in public transport much more of their travel is by car.
"What's more, rising fuel prices are hitting rural areas hardest, especially less well-off households where a higher proportion of income goes on essentials including transport costs. Greater car use in rural areas also contributes to higher overall carbon production rate per person than in urban areas.
Mr Russell says the CRC studies provide "a much-needed reminder of the critical transport challenges that face rural communities".
The studies or 'think-pieces' comprises:
* 'The contribution of transport to sustainable rural communities' - in collaboration with Transport Research Laboratory.
* 'Sustainable rural accessibility' - in collaboration with Integrated Transport Planning.
* 'Rural life without carbon' - in collaboration with MVA Consultancy.
* 'The implications of technological change for rural transport' - in collaboration with University of West of England.
* 'The potential impacts of road pricing on rural areas' - in collaboration with Universities of Plymouth and Aberdeen.
"We are anxious for these studies to provide thought-provoking insight into the possibilities for the future of rural transport and to stimulate further interest and discussion," says Mr Russell.
