RAPID MASS TRANSIT
The following table compares Toronto's RMT system with those of other principle cities and similarly sized metro areas in North America and around the world. For the purposes of this comparison we will define Rapid Mass Transit as any mode of public transportation which carries high volumes of passengers (as opposed to standard buses, streetcars, etc) while running at regular intervals of approximately 15 minutes or less (as opposed to most commuter rail systems, etc). This would generally include most subway and LRT systems. Comparisons are based on two main categories: LPA (Length Per Area - kilometers of system per square kilometer of service area) and PPS (People Per Station), which are calculated from rough estimates of each system's service area and population (determined by the area/population of the main city the system is centred in and any external regions the system might service). Data has been procured from UrbanRail.net and each city's respective transit authority (follow links below for further information).
