The document discusses personal rapid transit systems (PRT), which use small automated electric pod cars to provide point-to-point public transportation. PRT systems allow non-stop travel between origin and destination stations on a network of narrow guideways. Existing PRT systems provide on-demand, congestion-free service 24/7 at airports and universities. Upcoming PRT projects are planned in India, South Korea, and other countries to help address increasing transportation demands and limited land/fuel resources.

TRANSIT SYSTEM

2.  PersonalRapid Transit is a fully automated rail-
based public transportation system.
 Ituses small automated electric driven „pod cars‟
with capacity of 4 to 6 people, on a network of
narrow segregated guide ways .
 Stations are located on sidings ,with merge/ diverge
points. This approach allows for nonstop, point-to-
point travel, bypassing all intermediate stations.
2

3.  It is cost-effective ,provides highly “on-demand”
, congestion free and 24X7 operation.
 Any destination can be reached directly, in a private
atmosphere and without intermediate stops or
transfers with very short waiting times.

4. NEED OF PRTS !
 INCREASING TARNSPORT DEMAND
 As the population is increasing so the transport
demand, especially in urban cities where problem of
traffic have become a great concern.
4

5.  LIMITED LAND AND FUEL RESOURCES
 Mostof the metropolitan cities are already facing
problem of land shortage to manage the growing
population so , its very difficult to extend and
expand roads inside the city.
 Depleting natural gas and petroleum reserve is a
major concern, vehicle running on electricity can be
helpful in decreasing load on fossil fuel.

6. DEVELOPMENT OF PRTS !
 First PRT came into service at West Virginia
University ,Morgantown in 1972.
 It has 8.7 miles guide-way with 5 stations and 70 pod
cars with about 15,000 riders per day.
6

7.  In
November 2010, a PRT system went into
operation in Masdar City in the UAE. It has only 1.2
km of one-way track, serving the Masdar Institute of
Science and Technology.
 SinceSeptember 2011, Heathrow PRT is fully
operational, connecting business car park to the
central terminal 5 area through 3.8 km of guide way
and 18 podcars.

8. UPCOMING PROJECTS !
 InSuncheon, South Korea , PRT System will
connect Suncheon to the future site of the
International Gardening Festival with 9.8 km
guideway 2 stations and 40 podcars by end of 2013.
 In
India, Amritsar will have the first and largest
urban PRT System with route length of total 22km
with 35 stations. The initial phase connects 3.3km
route with 7 stations being 500m apart with cost of
60crore per km with 30 podcars. It will be open for
8
public in 2014.

9. INFRASTRUCTURE
 PODCARS :
 Fabricated Aluminium „Ladder Frame‟.
 Dimensions - 3.7 x 1.47 x 1.8 m
 Weighs 850kg with maximum payload of 500kg.
 13" Wheels with automotive tubeless radial tyres.
 Average speed is 40km/h.
 It is of two types on basis of usage :
a) short distance
b) high speed ,high capacity 9

11. GUIDWAYS
 The guideways are usually designed as elevated
systems with concrete and steel beams and columns.
 Theyare interconnected at “ junctions “ which
allows podcar to select various paths.
 Guideway density and extent is determined by
maximum walking distance to nearest station and
number of origin and destination point to be served.
11

12. SPECIFICATIONS :
12

13.  TypicalElevated Guideway Headroom for main road
crossings is 5.7m whereas 2.5m over pedestal
crossing.
 Typicalcolumn weighs 10 tonnes with dead load
requirement of minimum 2.2kN/m².
 Guideways can be integrated into existing building
without significant strengthening or modifications.
13

14. STATIONS
 Off-linestations are designed with a “siding” track
or so that vehicles not stopping at a particular station
can bypass that station .
 Usinga 30 second dwell time, one typical station
bay can serve about 120 Pods per hour.
 These stations have all basic facilities ex passenger
interface which allows destination selection
14
console, communications, and segregation doorset.

16. OPERATING COST
 Podcars costs 92k USD each and Infrastructure
costs 4.6M USD/km with general formula of overall
cost:
1.23 (1,600 + 67.0(L-5) + 11.0(N-25)) K USD
*per annum
Where L is the length of single track
guideway (km) , N is the number of vehicles

17. SAFTEY AND SECURITY
 No human error so much safer than vehicles on road.
 Running gear mechanism to prevent derailment and
grade-separated guideways prevent conflict with
pedestrians or manually controlled vehicles.
 Public
transit safety engineering approaches, such as
redundancy and self-diagnosis of critical
systems, are also included in designs.
17
 Less crowded so less prone to terrorist attacks.

18. PROPULSION
 Electricitypowered 7kw linear induction motors and
rotary motors used.
 power is generally transmitted via lineside
conductors
 Systems retain a small on-board battery to reach the
next stop after a power-failure increasing the safety
and reducing the complexity, cost and maintenance
of the guideway.
 Laser sensors maintains vehicle to prescribed
path. 18

19. SWITCHING
 Two types of switching:
 Vehicle-switching
 permits faster switching
 Simplifies the guideway, makes junctions less visually
obtrusive and reduces the impact of malfunctions
 Track-switching
 replaces in-vehicle mechanisms with larger track-
moving components.
 simplifies the vehicles, reducing the number of small
19
moving parts in each car.

20. APPLICATIONS
 Airport shutles : connecting parking to terminals etc.
 Private property developments : ex educational
institutes , private firms and industry etc.
 Shortdistance urban connections: connecting tourists
spots etc.
 Fasterouter suburban connections:connecting
industrial areas to city center etc. 20

21. CHARACTERISTICS
 PRT is sustainable.
 PRT is safe.
 PRT produces zero local emission.
 Infrastructure fit within most urban fabric.
 PRT offers a 24h, on- demand, direct origin to destination
service.
 PRT has relatively low capital costs.
21
 PRT is accessible for all

22. IMPEDIMENTS TO DEVELOPMENT
 There is very less tested.
 There is a lack of awareness of the concept.
 Would not produce much employment.
 Financialrisk as implementing test program requires
substantial finance support .
 PRT may attract vandalism and pods may be target of crime.
22
 Not feasible for rural areas.

23. CASE STUDY

24.  Terminal 5 at London Heathrow Airport is connected
to its business passenger car park, by a 3.8 km PRT
system.
 Since september 2011 it is fully operational.
 The system cost £30 million to develop.
 The pods use 50% less energy than a bus.
 It
uses 18 podcars that runs 22 hours a day with 24
maximum speed of 40km/h.

25.  Operational
statistics in May 2012 demonstrate more
than 99% reliability .
 Average passenger wait time over the one year
period of 10 seconds.

26

27.  The route will focus on railway and bus stations to the
Golden Temple .
 The land area required for transportation will reduce by 30%.
 The project costs nearly Rs 250 crore and is to be taken up on
a public-private partnership.
