Despite the development of information and communication technologies, mobility still remains an important factor in the development of the social capital, by promoting social interactions. However, rural African populations face more difficulties getting around than city dwellers. In addition, studies on mobility in Africa are relatively weak. In rural African areas, this ignorance of mobility is even more important. It is necessary to identify the characteristics and the spatial structure of mobility flows before starting any reflection on solutions, particularly in terms of spatial allocation of transport resources. Our main objective is to map the current movement flows in the Niakhar area. We chose to use the cartographic approach to analyze mobility flows. The data come from a survey carried out in 2018, as part of the French Institute of Research for Development (IRD) Niakhar Atlas project. For the data analysis, we used 4 methods: dominant flux method, net flux calculation method, directional mean statistics and areal interpolation. The results revealed differences in mobility behavior depending on the season and in space, and the existence of three dominant centers: Ngayokhème, Diohine and Toucar. They also made it possible to highlight the main directions of the flows and the scalar fields of mobility.

Ensuring rural mobility through Demand Responsive Transport, Experiences from Austria

引用

Journal of Agricultural Science and Technology 2010年第6期4卷 96-103页

作者： R. Klementschitz Institute for Transport Studies Department of Spatial Landscape and Infrastructure Sciences University of Natural Resources and Applied Life Sciences （BOKU） Vienna 1190 Austria

Embedded in an INTERREG IVc project called Flexible Transport Services （FTS） and Information and Communication Technology （ICT） platform for Eco-mobility in urban and rural European areas （acronym： FLIPPER）, the University of Natural Resources and Applied Life Sciences in Vienna, Austria, analysed impacts of Flexible Transport Services focusing on Demand Responsive Public Transport （DRT）. This includes the analysis of site characteristics, the existing mobility demand, accessibility, area needs, current environmental impact, operational, financial and organisational constraints; designing of the service and definition of the supporting organisational measures required. Examples of realised services in Alpine areas in Austria confirm the effects on people＇s daily mobility and all its consequences towards society and environment. Main effects are the decrease of public funding needs and ensuring a basic transport supply even in rural areas. Additionally, there is a strong component of social inclusion in this service, increasing the quality of life capable to contribute to the deceleration of the out migration. As secondary effects, economic effects and environmental effects can be observed. The potential of these services are not fully utilised today and can be achieved through further extensions of service area as well as technical developments.
