Basic Specifications for SkyWeb Express
March 9, 2004Cabin
- Exterior Dimensions: 102.5in (250.4cm) long x 66.2in (168.2cm) high x 60.2 in (153.0cm) wide
- Seat: 54in (137.2cm) wide; Bottom of seat is divided into 3 parts, each able to flipped up individually, useful for accommodating mobility devices [eg, wheelchairs], a bicycle, or other items
- Payload Capacity: 650lb (294.9kg)
- Gap between guideway and cabin: The cabin is fastened to the vehicle chassis, which rides inside the guideway, via two vertical pylons; Allow 1in (2.5cm) high spacing between the bottom surface of the cabin and the top of the guideway covers
Chassis
- Length: 9ft 5in [113in] (2.87m), including the front and rear shock absorbers [bumpers]
Guideway, Posts, Brackets
- Guideway Exterior Dimensions: Cross-section 36in (91.4cm) wide x 38in (96.5cm) high, including covers
- Guideway Slots: A 4in (10.2cm) wide slot runs longitudinally along the top of the guideway between the covers, through which pass the two pylons connecting the vehicle chassis and cabin; An 6in (15.3cm) wide slot runs along the bottom between the guideway covers
- Posts: Can vary in height; 16.0ft [192in] (4.88m) high is usually assumed for basic planning purposes; At 16ft (4.88m) high the post is 10in (25.4cm) diameter at the top and 22in (55.9cm) diameter at the ground
- Post Brackets: Fasten the posts to the guideway internal truss structure; Configured in "X" form [plan view] ~24in (61.0cm) wide on both sides of the top of the post in the direction of the guideway, ~14in (35.6cm) wide on both sides of the post laterally across the underside of the guideway
- Post Bases: The dimensions depend on the kind of footing, which depends on soil conditions.
- Spans: Maximum span with basic unmodified guideway structure is 90ft (27.4m)
Weights
- Vehicle: 1,000lbs (453.6kg) Cabin and chassis, empty
- Vehicle: 1,650lbs (748.4kg) Cabin and chassis, fully-loaded
- Guideway: 135lbs/ft (200.9kg/m)
- Guideway and Vehicles: 310lbs/ft (461.2kg/m); Assumes fully loaded vehicles one after the other nose-to-rear on the guideway, an extremely unlikely scenario
Gradient Capability
- Nominal design air-cooled LIM [linear induction motor] rating: 15% gradient 30ft (9.1m) high at 30mph (48.3km/h) ; 15% gradient 50ft (15.2m) high at 40mph (64.4km/h)
- Higher line speed going into the gradient yields greater lift; Lower gradient percent yields longer lift.
- LIMs can be rated, within limits, for higher gradients; Water cooled LIMs would yield higher gradients
Curves, Curve Radii
- Guideways in curves are superelevated [banked]
- Nominal design specifications: Superelevation 12% or 6.843deg; Maximum lateral acceleration and comfort jerk 0.25g
- Curve radii will increase exponentially with line speed going into the curve
- For radii at nominal specifications and various line speeds, contact the Taxi 2000 Corporation
- Minimum curve radius: 36ft (11.0m) at 14mph (22.5km/h)
Stations
- Minimum Berthing Space: 10.0ft [120.0in] (3.0m) per berth; "Lb" in formula following
- Outside Barrier: Since the cabin door wraps completely around the cabin shape, thus opening on both sides of the cabin, there must be a barrier or parapet running along the far side of the in-station section of the offline station guideway approximately 2in (5.1cm) from the side of the cabins
- Offline Station Guideway Length: Can be computed per following formula:
Lo = ((2Nb + 2)Lb) + (2Lt)
where
Lo is the Length of the offline station guideway
Nb is the Number of berths
Lb is the Length of a berth
Lt is the Length of the transition as computed in "LT" program [proprietary]Contact Taxi 2000 Corp to have LT program run
Input parameters needed: Mainline guideway line speed by the station; Separation between mainline and station guideways [center lines]– usually assumed to be 10ft (3.0m); Sample runs, assuming 10ft (3.0m) separation:
- Lt = 56.0ft (17.1m) @ 10mph (16.1km/h)
- Lt = 69.9ft (21.3m) @ 14mph (22.5km/h)
- Lt = 71.5ft (21.8m) @ 15mph (24.1km/h)
- Lt = 84.7ft (25.8m) @ 20mph (32.3km/h)
- Lt = 104.2ft (31.8m) @ 25mph (40.2km/h)
- Lt = 131.6ft (40.1m) @ 30mph (48.3km/h)
- Station Access from Street: Access to all stations will be provided by at least one set of stairs and at least one handicapped accessible elevator in each station. If the station is an in-building type, existing stairs and elevator nearby will suffice
- Ticketing/Farecard Machine: If the system requires collection of fares, each station will have at least one ticketing/farecard machine at which single or multi-use farecards can be purchased
- System Map: Each station will have at least one map of the system via which passengers can determine the number or code of their destination station
- Berth Stanchions: Each berth in each station will have a stanchion located at each berth to the left or right side of the cabin door with a keypad via which passengers can enter their destination station number or code; if the system requires fares each stanchion will also have a farecard slot for swiping the farecard to enable card validation; destination can also be entered via a touch screen
Line Capacity
- Maximum flow: Two vehicles per second; i.e., 7200 Vehicles per hour at 0.5 second headway
