By means of cyclomatic number C, index α, index β, and index γ inherent in graph theory, this paper shows the bad connectivity of Mbujimayi town (that is 18% of connexion). To ameliorate it, we propose, on the one hand, the reorganization of actual highway network providing a long bypass to which others axis will connected, and on the other hand, to rehabilitate some main roads, to bridge small and big ravines, to plant bamboos or vetivers on the embankments of ravines preventing the gully erosion. From this system rehabilitated, the connectivity indices calculated show that the highway network is completely ameliorated (that is 55% of connexion).

Abstract
By means of cyclomatic number C, index α, index β, and index γ inherent in graph theory, this paper shows the bad connectivity of Mbujimayi town (that is 18% of connexion). To ameliorate it, we propose, on the one hand, the reorganization of actual highway network providing a long bypass to which others axis will connected, and on the other hand, to rehabilitate some main roads, to bridge small and big ravines, to plant bamboos or vetivers on the embankments of ravines preventing the gully erosion. From this system rehabilitated, the connectivity indices calculated show that the highway network is completely ameliorated (that is 55% of connexion).

Abstract: (french)
Par l’entremise du nombre cyclomatique C, des indices α, β, et γ inhérents à la théorie des graphes, notre réflexion démontre la mauvaise connectivité de l’actuelle trame viaire de la ville de Mbujimayi (18% seulement de connexion). Pour améliorer cette connexion, nous avons proposé, d’une part, le réaménagement du réseau routier par la construction d’une rocade à laquelle viendraient se greffer quelques bretelles, et d’autre part, la réhabilitation des principaux axes routiers, la jetée des passerelles sur les artères ravinées et des ponts sur les méga-ravins ainsi que la végétalisation de leurs berges pour lutter contre l’érosion ravinante. De ce réseau réaménagé, nous avons extrait le graphe topologique et calculé les différents indices susmentionnés. Les résultats ainsi obtenus révèlent qu’il y aura une nette amélioration du réseau routier soit 55% de connexion.
