Abstract: In this paper, percolation-based street network connectivity is studied for two types of networks from transit systems: first, networks from a fixed route transit (FRT) and second, networks from a flexible route transit (FXRT). Application examples with Route 121 from Long Beach Transit for FRT show that the connectivity of a section of the route analysed is up to 67%. With FXRT example using five Call-n-Ride (CnR) Denver RTD, the connectivity is found to be the highest for Interlocken with street connectivity up to 14.4%. The street network from all the five CnR systems appeared to be poorly connected for drop-off or pick-up of passengers. This research would serve as a benchmark to studying several other percolation-based properties of porous media that can be successfully applied to modelling network connectivity of other modes of transportation such as rail and freight trucks.
