3. INTRODUCTION
One of the problems created by road
traffic is PARKING. Not only do
vehicles require street space to
move about, but also do they
require space to park where the
occupants can be loaded and
unloaded.
A systematic study of the PARKING
CHARACTERISTICS and DEMAND and
REGULATORY MEASURES that are
possible for controlling parking is
of great help to a traffic engineer
as well as town planner.

4. INTRODUCTION CONTINUED . . .
. . . . .• The period over which a car is parked is very great compared with the time it is
in motion. The size of average parking space is 14 m2. It is roughly estimated that
out of 8760 hours in a year, the car runs on an average for only 400 hours,
leaving 8360 hours when it is parked.
• Every car owner would wish to park the car as closely as possible to his
destination so as to minimize his walking. This results in a great demand for
parking space in those areas where the activities are concentrated.

5. NEEDFOR THE STUDY
Various metro cities like Delhi, Bombay in India is now become a most congested city in India.
High volume of traffic consisting of both fast and slow moving vehicles is plying through the road.
The growth rates are reflected in the growth of traffic volume on the roads, thus leading to congestion
and subsequent reduction in speed. So it has become necessary to project the future traffic growth and
thereby finding out the requirement of increase in carriage way widths required to carry this traffic.
The parking space provided is not sufficient to meet the parking demand. Hence it is necessary to
conduct a detailed analysis of the traffic characteristics and parking demand of the area.

6. VARIOUS PARKING SIGN

7. There are various effects of wrong parking
on
society as well as on environment -
CONGESTION ACCIDENTS
OBSTRUCTION
TO FIRE
FIGHTING
OPERATIONS
EFFECT ON
ENVIRONMET
ILL-EFFECTS OF PARKING

8. CONGESTION
• One of the serious ill-effects of parking is the loss of street space and
the resulting traffic congestions.
• The capacity of the streets is reduced, the journey speed drops down and the journey
time and delay increase. The operational cost of vehicles is thereby increased, causing
serious economic loss to the community.

9. ACCIDENTS
• The consequences associated with wrong parking and unparking are
known to cause road accidents.
• Careless opening of the doors of parked vehicles, moving out of a parked
position and bringing a car to the parking location from the mainstream of
traffic are some of the common causes of parking accidents.

10. OBSTRUCTION TO FIRE-FIGHTING
OPERATION
• Parked cars obstruct the movement of fire fighting vehicles and
greatly impede their operations. They block access to hydrants
and access to buildings.

11. EFFECTS ON ENVIRONMENT
Parked vehicles degrade the environment of the town Centre.
Stopping and starting of vehicles result in noise and fumes.
Cars parked into every little available space debase the visual
aesthetics and “buildings seems to rise from a plinth of cars”.
In spite of the above ill-effects, parking has to be allowed on the
streets or off the streets close to the user’s destination.
The well being of the community and the town Centre demands that
great thought should be bestowed with the parking needs and how
best to fulfill them.

12. SOME COMMON TERMS USED IN
PARKING FACILITIES
PARKING ACCUMULATION
PARKING VOLUME
PARKING LOAD
PARKING DURATION
Percentage of parking bays actually occupied by parked
vehicles as compared to the theoretical number available.PARKING INDEX
The total number of vehicles parked in an area at a
specified moment.
The number of vehicles parked in a particular area over a given
period of time. It is usually measured in vehicles per day.
The area under the parking accumulation curve during a
specified period.
The length of time spent by a parked vehicle in a parking
space.

13. CLASSIFICATION
OF PARKING
FACILITIY
ON – STREET OR KERB PARKING
OFF – STREET PARKING

14. ON-STREET OR KERB PARKING
 In this type of parking vehicles
are parked on the kerb or
sections which may be designed
for parking.
 Kerb parking is quite
convenient for those who could
find a suitable space to park
their vehicles near to the place
they wish to stop, but for others
who could not find a parking
space it is a problem and often
they may have to park their
vehicles at a far off place you
know and walk done to
destination.

PARKING

15. THE VARIOUS PATTERNS OF
“KERB PARKING”

16. OFF-STREET PARKING
On-street parking can only solve a part of the paring problem. For a
satisfactory solution various types of off-street parking facilities are also
be considered. The types of off-street facilitates commonly considered
are :
 SURFACE CAR PARKS
 ROOF PARKS
 MECHANICAL PARKS
 UNDERGROUND CAR PARKS

17. SURFACE CAR PARKS
 Surface car parks properly
located and developed on a
piece of vacant land.
 Great care is needed in their
design and operation. A variety
of layouts is possible depending
upon the area.
 A stall size of 2.5 x 5m is
probably adequate for INDIAN
CONDITIONS , predominated
by small size cars.
 for AMERICAN CONDITIONS
2.6 x 5.5m is recommended

18. ROOF CAR PARKS
 A very popular method of solving
the parking problems adopted in
many cities is to park the vehicles
on ROOF -TOPS.
 Access ramps or mechanical lifts
provide the necessary access to
roofs.
 To economies, many roofs may be
linked together served by a single
access ramp.
 An extensive system of linked car
parks at roof level, integrated with
multi level, integrated with
multistoried parking garages is in
use.

19. The great advantage of
underground car parks is that ,
least inappropriate welcome
they cause to the aesthetics of a
place.
These parking can be built in
the basement of any
multistoried building or below
open spaces.
Since the work involves large
quantities of excavation,
construction of retaining walls,
ventilation and lighting such car
parks tend to be very costly.
UNDERGROUND CAR
PARKS

20. PERIPHERAL PARKING SCHEMES
There are some alternatives parking options which
serves better parking facilities in the area, having
less space. These are : -
 PARK AND WALK
 PARK AND RIDE

21. PARK and WALK
 Under this scheme the motorist are made to park their vehicles at
the outskirts of the town.
 After that the rider / driver have to walk down to the town
Centre.
 The attraction is in the form of lower parking charges at the
periphery than at the town Centre or no parking charges at all.
 The less charges and other attractions should be very much
attractive if the scheme has to succeed.

22.  This scheme provide for peripheral parking facilities and public transport
side to the destinations in the town centre.
 This is an attractive scheme and has been tried with success in many
towns.
 For success, the total travel time including parking time, waiting time at
the bus stop and travel time by bus should not be excessively high to make
him look at it with disfavour and decide to bring the car to the town centre
in spite of the high parking charges there.
 Also, the cost of peripheral parking plus the charges for his journey by
bus should be less than the cost of travel by his car plus the charges for
parking at the town centre.
PARK and RIDE

23. Parking studies usually are prerequisite to developing
new or expanded parking programs. The studies should
be designed to :
Inventory of existing parking space supply and measure current
levels of space usage (accumulation and space turn over).
Identify salient parking characteristics (duration, purpose, trip
destination and walking distances to destination).
Qualify demands and needs.
Estimate facility capital and operating costs, usage and revenues.
PARKING STUDIES
and
SURVEYS

24.  Parking studies provide the data essential to develop programs to meet
parking needs.
A parking study may be concerned with an individual trip generator or facility,
such as a hospital or office building, or with the entire CBD. It should
determine not only where motorists can and do park, but also where they
would like to park and how there parking practices affect other transportation
facilities.
Full scale, comprehensive parking studies involving extensive data collection
through parker interviews and other means, and detailed analysis provide a
sound basis for estimating parking usage and determining appropriate actions.
A limited parking study may rely on measuring parking usage by hourly
accumulation counts of parked vehicles or facility occupancy checks.
PARKING STUDIES

25. The types of parking surveys are usually conducted
as follows:
Parking Space in inventory
Parking Usage Survey by Patrol
Questionnaire Type Parking Usage Survey
Cordon Count
PARKING SURVEYS

26. The first step in a parking survey is to collect data and amount,
type and location of space actually or potentially available for
parking in an area.The area to be surveyed should first
described.The Central Business District [CBD] is usually the
area where the parking survey is needed.The items to be
recorded include the following :
Parking Space in inventory
 FREQUENCY OF PATROL : Generally half N hour.
 METHOD OF OBSERVATION : A tape recorded may also be used to record
the registration numbers of vehicles.
 TIMING OF THE SURVEY : During working days.
 EQUIPMENT AND FORM OF RECORDING : Each observer will be equipped
with a watch, pencil, supply of forms, a map of the street and a form.

27. The questionnaire Type Parking usage survey involves interviews with
the drivers who use the parking facilities.
As a result it is possible to collect information on the extend to which
existing facilities are being used, the parking requirements at the
process existing at the time of survey, the distribution of demand over
the area and time and journey purposes of car parkers.
In this interview of actual parkers, the information collected should
include:
Questionnaire Type Parking usage survey
• Address of origin of trip
• Address of destination of trip
• Trip purpose
• Time of arrival at the parking place
• Time of departure from the parking place
• Type of parking space used
• Type of vehicle used

28. Land use survey
Parking mainly depends upon the land-use pattern.Shopping centers
attract more people towards them than most other land-uses. But, the
parking requirements of different Commercial centers are not the same.
They vary from one to one. Some Commercial centre attracts more
customers to it.
Commercial centers are classified into two :
 Customer attractive Commercial centers
 Non-customer attractive Commercial centers
The nature of the Commercial centre was decided by making observations at the
particular site for 1 hour. Commercial centre in which more than 5 customers visited
within 1 hour was taken as CUSTOMER ATTRACTIVE COMMERCIAL CENTRE ;
otherwise it was taken as NON-CUSTOMER ATTRACTIVE COMMERCIAL CENTRE.
Shops like textiles attracted more customers whereas in Beauty Parlors, Printing shops
etc. customers were less.

29. DIVISION OF BUILDINGS
ACCORDING TO PARKING DEMAND
For all the sections need parking the buildings are
divided into :
 Customer Attractive Shops (CAS)
 Non-customer Attractive Shops (NCAS)
 Customer Attractive Office (CAO)
 Non-customer Attractive Office (NCAO)

30. No Customer attractive Shops Non-Customer attractive shops
1 Textile Electricals
2 Vegetable Shop Printing Shop
3 Restaurant Furniture
4 Stationery Grocery Shop
5 Flower marts Beauty Parlour
6 Fancy Shop Tailoring Shop
7 Internet café Hotel
8 Photostat shop Mill
9 STD Booth Appliances
10 Bakery Electronics Shop
Number Customer attractive Office Non-Customer attractive Office
1 Bank School
2 Post Office Government Offices
 In some offices, there was not any customer whereas customers in addition to employees
were seen in some other offices. The parking space required for the latter type is more.
Based on this the offices are classified as customer attractive and Non-customer attractive
offices -

31. MODERN AND CREATIVE METHODS
TO REDUCE PARKING PROBLEM IN
METRO CITIES
Basically there are two method which are largely adopting in various
metropolitan cities like Delhi , Noida , Bangalore and Mumbai etc.
 Multistoried Car Parks
 Puzzle Car Parking

32.  Multistoried parking garages are
restored to when the floor space
available for the parking garage is
less and is very costly.
 It is possible to construct
multistoried garages to park a large
number of cars at a time.
 It is necessary to provide the inter
floor travel facility for the vehicles,
such as elevators, ramps, etc.
 Multistoried car parks are
designed for a capacity of about
400 to 500 cars.
MULTISTORIED CAR
PARKS

33. Some of the desirable standards for
designing of the multistoried car parks
are :
 GRADIENT OF THE RAMP : 1 in 10 generally and 1 in 8 for very short ramps
 PARKING STALL DIMENSIONS : 2.5m x 5m
 CLEAR HEIGHT BETWEEN FLOORS : 2.1m
 INSIDE RADIUS OF CURVES : 7m
 WIDTH OF TRAFFIC LANE ON RAMPS AND ENTRANCES : 3.75m
 GRADIENT OF SLOPPING FLOORS : Not steeper than 1 in 20

34. PUZZLE CAR PARKING

35. CONTD. .
• This System Is
Electromechanically
Operated. Fast IN & OUT
Of The Cars Is Possible.
• Combination Of Multiple
Levels Vertically &
Horizontally Is Possible
• Mostly Preferred In
Residential Complexes, IT
Parks Commercial
Complexes, Malls, Hotels
Etc.
Suitable for :
Sedan Car For All levels &
SUV Car For only ground level.

36. CONCLUSION
As we know, The Numbers of vehicles are going on increasing at an
alarming rate and commercialization of the area is also happening at a
fast rate, thus demanding more parking spaces near the destination. All
these factors correspond to generate various parking
problems.Consequently it have various Congestion, Accidental problems
and it adversely affect the fire-fighting operation and Nature.
Thus Parking structures will need to be reconsider the
technology especially if they are located in heavy traffic areas. The
available legal parking spaces will have to be utilized to highest
efficiency. We have to follow the various parking policy while meeting
some parking needs and also lower the personal vehicle travel and urban-
peak traffic to reduce congestion, accidents and pollution. Now there is a
need of modifying existing parking facilities and construction of new
parking facilities such as puzzle car parking, Multilevel Parking
facilities, Underground parking and Roof Car Park etc.
