“…In the network shown by this figure, nodes 11 and 18 are not serviced, nodes 8,14,15,16,17,19 and 20 are hub stations, and the remaining nodes are spoke ones. The network consists of two hub lines, determined by line paths along stations (17,14,15,16) and (8, 15 ,19 ,20) and four spoke lines by the line paths along stations (1,5,9,13,14), (2,6,10,15), (3,7,12,16) and (4,8). The RTN design model proposed based on hubs and spokes has potential applications in designing new RTNs such as subways, BRT systems and multimodal systems in large cities, as in developing countries.…”
