The efforts made to plan cities in emerging and developing countries are confronted to multiple issues, especially in small and middle sized cities which can be considered as poor through several criteria: socio-economic level of majority of population; low levels of public investments, weak quality of local administration, and large dependence of external donors. Following several authors, one...

This paper proposes a novel generalisation model for selecting characteristic streets in an urban street network. This model retains the central structure of a street network. It relies on a structural representation of a street network using graph principles where vertices represent named streets and links represent street intersections. Based on this representation, so-called connectivity gra...

Urban Mobility systems play an increasingly important role in the way people move around their communities and how communities develop. Despite the significant benefits to using public transportation, many potential riders are reluctant to utilize public transportation. In this current situation, cities and communities are increasing efforts to provide multiple solutions for urban mobility and ...

Golem is an holonomic robot designed to be compliant with Robocup regulations for the middle-sized league. The project consists in three parts: mechanics and hardware, vision system and software. We adopted the universal three wheels model to achieve a great freedom of movement. In order to take advantage of this particular feature, the vision system has to give a full sight of the environment....
