• Rapid
• Urban
• Flexible

RUF International
2
Dualmode
Individual or collective
3
RUF drive system (patented)
Simple mechanically Same motors for both rail
and road Derailment impossible Smooth support
wheels with low rolling resistance Very low
noise - More wheels than normal
4
RUF power from monorail
Power from guideway Batteries are recharged
on guideway Only small batteries are needed
5
RUF slender guideway
85 cm wide 20 m long modules Produced on
factory Erected on site Optimized
construction Room inside Minimum visual
impact
6
RUF is better than the car
7
RUF is ready anytime

• Parked nearby
• No start motor problems
• No noise at start
• No cold start emissions
• Slight battery discharge

8
RUF can drive anywhere
RUF can use the very extensive road network
Range on batteries is 10 times longer than
normally required (lt3 km to get to network) A
hybrid unit can extend the range using gasoline
or hydrogen Range is virtually unlimited if the
network is extended
9
RUF uses very little energy
Electric propulsion is very efficient Power
from the guideway directly to motors Low air
resistance when coupled in trains (gt60 of the
time and gt90 of distance on the guideway) Low
rolling resistance on guideway due to smooth
support wheels. Emergency braking via rail
brake Efficient regeneration of braking power
No transmission loss between motor and rail
10
RUF can use wind energy
Synergy using masts from windmills Low
transmission losses Guideway contains power
cables from windmills Highest energy
consumption at high winds
11
RUF can use solar energy
Triangular guideway ideal for solar cells
Very low transmission losses - Shadow from
vehicles 10 of the time during rush hours
12
RUF is faster than the car

• RUF has a top speed of 150 km/h
• Average speed in a typical 5 km network is 122
  km/h
• The flow is continuous (30 km/h in junctions)
• Slow driving is impossible
• No overtaking is possible
• - Slowdown to 30 km/h every 5 km

13
RUF is safer than the car
No highway accidents Riding on top of a
triangular guideway is extremely safe Automated
driving is safer than manual driving No problem
with fog and darkness
14
RUF can handle snow
RUF is locked to guideway Snow piles does not
disturb RUF Rain is not collected on guideway
Snow cleaning robot can clean the guideway
Pressure against the guideway can increase the
friction
15
RUF is comfortable
Very low noise Very smooth ride Rolling
office gt you can earn money while you commute
Constructive time
16
RUF can serve Värmdö

• 100 km double RUF monorail and 19 junctions
  cost approx. 3.5 bill. SEK
• Average speed on network gt 100 km/h
• Energy consumption reduced to lt 1/3 compared to
  car
• No serious accidents on monorail
• Very low noise
• No animals killed

17
RUF can serve Värmdö
RUF
PRT

• RUF can cover Värmdö 100
• - PRT only covers to 400 m from stations and
  pass. will have to carry luggage

18
RUF can avoid congestion

• RUF is an elevated system for cars and busses
• Traffic flow can be controlled so that
  congestion on network can be avoided
• Automated parking in city can prevent too many
  cars in the streets
• - Careful planning of egress ramps is necessary

19
RUF users can relax

• RUF drives itself on the monorail
• Commuter time can also be used to work
  electronically and earn money
• - Users have to be ready at exit or they will be
  parked automatically and get a ticket

20
RUF is door to door transit

• RUF public transport is very attractive
• Car drivers might want to use it
• Door to door transport is possible
• Electric busses can be tolerated anywhere
• No noise
• No pollution

RUF has been tested
