Automated vehicles, ticketing and control; 24-hour service, demand-responsive, fully-developed vehicle prepositioning capability (i.e. placing empty vehicles that are ready for use in locations where demand is expected to materialize).
One-way loops, some adjacent for two-way travel in particular corridors, adapted closely to site requirements
All stations are off-line
One or more storage/maintenance depots, located to minimize the movement of empty vehicles around the network.
Distance between Stations: Around 500 meters or less
Line Capacity: From 1,500 to 8,000 passengers per hour each way; on certain lines with higher capacity to be achieved later
Station Dimensions: The smallest possible footprint/structure
Elevation of structure variable, depending on each particular case
Station capacity: At least 300 passengers per hour per berth
Station Numbers and Locations: Numerous enough and sited so that around 85% of potential patrons can walk to/from in 5 minutes or less
Minimum radius of curvature: 30-50 meters
Possible grade: up to 10%; superelevation on curves possible
Minimum required characteristics:
Length of trip, ride time, average speed
-- 2 km, 6 minutes, 20 km/hr
-- 4 km, 9.6 minutes, 25 km/hr
-- 6 km, 20 minutes, 30 km/hr
-- 8 km, 20 minutes, 40 km/hr
Reasonable possibility of recovering Operating and Maintenance (O&M) costs or even covering capital costs and making a profit
All passengers seated
Space provided for parcels
Easy access for elderly people and children
Special on-call vehicles for disabled persons
Climate controlled
Workable emergency evacuation capability from vehicles and elevated structures
Monitoring and response systems capable of dealing with a varity of personal safety concerns
Structures should be able to be installed on streets less than 20 meters wide
Construction should not require substantial and lengthy disruption of adjacent areas
As unobtrusive as possible; structural flexibility designed to be as attractive as possible; customized to satisfy local tastes.
Stations custom-designed to satisfy local desires Storage/maintenance facilities sited to minimize local impact
Much less than that of a heavily traveled arterial street (standards need to be defined)
Capital costs: Should, in general, come to between $10 and $20 million (2001) dollars per system lane-kilometer (includes stations, vehicles and all other necessary facilities)
Possibility of increasing the initial capacity later on
Possibility of improving the initial network as well as extending it into other nearby areas Possibility of adapting the initial system to new technologies as they become available Cargo carrying capabilities
Vehicles capable of carrying containerized and non-containerized goods, automated loading/unloading possible
Manufacturing flexibility, system component requirements can be met in more than one way
Maximize use of widely available components having multiple, well established suppliers in most parts of the world
Modular design capable of being built by a variety of licensed manufacturers
