Subways in NYC on 3 minute headways at 2000 passengers per train carry 40k per hour; where they are stacked (the Lexington or 8th Avenue Line) one lane carries two tracks in the "space" of one lane and 60k-plus at peak times.<br /><br />Signals limit the Red Line, but crush capacity does as well. Once trains become at all bunched, dwell times increase and bunching exacerbates, slowing service for emptier trains behind. NYC trains which run express for two miles or more have more running and fewer stops which minimizes this issue.<br /><br />I'm wondering whether the new Longfellow (this is off topic and needs to be a separate post) could have two lanes; the right-most a wider bike lane in the mornings and on weekends, and a traffic lane in the evenings, when there is a worry about the bridge backing up in to Kendall Square and snarling traffic (and bus transit) there.Arihttps://www.blogger.com/profile/06058285362842737187noreply@blogger.comtag:blogger.com,1999:blog-293100068373105830.post-52698200021551172992013-06-16T22:56:41.052-07:002013-06-16T22:56:41.052-07:00Buses running in a dedicated lane could probably m...Buses running in a dedicated lane could probably manage 6000 passengers per hour, though it does require quite a lot of buses. Streetcars running in a dedicated lane could quite easily exceed it, given that they can be made longer than buses. And a full on metro can carry much more than 10,000 passengers per hour. By my calculations, the Moscow Metro can do about 45,000 per hour in dense, but not crush-load, conditions, at the peak service level currently provided. By comparison, the Red Line hs slightly shorter (but slightly wider) trains. The real problem though is the signal system, and possibly dwell time at the central stations, which limits the overall line capacity to 4.5 minute headways when 1.5 might be possible with the same tracks, trains, stations, and signalling technology.crzwdjkhttps://www.blogger.com/profile/06394805356595604336noreply@blogger.com
