2. The Even Odd FormulaThe Even Odd Formula
The Even Odd formula works in a way
that even numbered vehicles to run on
even days while odd number vehicles will
run only on odd days.run only on odd days.
It is being implemented for January 1-15
on a trial basis.

3. Even Odd FormulaEven Odd Formula
Many reasons may be given in favor or
against the formula and its expected
success, but one thing is certain.
This clearly shows the alarming level ofThis clearly shows the alarming level of
Delhi pollution, and Government’s
willingness for its abatement.

4. Other OptionsOther Options
To me, multiple strategies must be applied
to counter the problem of Delhi
pollution.
In the next slides, I am going to presentIn the next slides, I am going to present
some of these.

5. Particulate MatterParticulate Matter
Presently, most severe problem comes
from PM10 and PM2.5.
These are nothing but very fine dust
particles of size around 10 and 2.5particles of size around 10 and 2.5
microns.
Due to being of very fine size, these do
not settle down easily and remain in air
for long time.

6. Use of AtomizationUse of Atomization
Fine water droplets have a very high
surface area, and are capable of attracting
suspended particulate matter in air.
Installation of Atomizers (foggers) atInstallation of Atomizers (foggers) at
different places particularly PM10 rich
areas can be done to ‘wash off’ the
polluted air.

7. Space Required for FoggersSpace Required for Foggers
At most places there are wide dividers on
the roads. Such foggers may be installed
on these dividers, where these can
effectively trap dust particles emittedeffectively trap dust particles emitted
from vehicles.

8. Water RequirementsWater Requirements
This will need adequate quantities of
water. If possible, treated effluent from
various industrial units can be used for
this purpose.this purpose.

9. Side AdvantagesSide Advantages
In addition to cleaning the air, this will also
result in relatively increased humidity
levels.
This locally increased humidity will not beThis locally increased humidity will not be
a problem as the scheme should be
implemented where particulate matter is
high, indicating reduced humidity levels.

10. Increased HumidityIncreased Humidity
More humidity means more possibility of
forming dew and hence the suspended
particles get grounded.
This will also help in maintaining greenThis will also help in maintaining green
cover in the divider areas of roads.

12. Reduce IndividualVehiclesReduce IndividualVehicles
Many people use private vehicles just
because they want to show off.Well, such
people are lesser in number.
More and more people are forced to useMore and more people are forced to use
their vehicles just to save time, effort and
have a convenience.
Next slide shows a roadmap for the
same.

13. CessCess
A Cess on Petrol is applied for all petrol
pumps operating in Delhi.
The cess amount collected is used only
in buying more and more vehicles underin buying more and more vehicles under
public transport.
Typically, we must be having at least 10%
number of buses compared to the
number of cars.The figure may be
modified depending on experience.

14. Limiting Load FactorLimiting Load Factor
A load factor survey must be done
regularly and displayed online. Suppose
there are 100 buses moving from Anand
Vihar to ITO in a day. In all of these,Vihar to ITO in a day. In all of these,
maximum occupancy should be limited to
less than 90%. In case there are more and
more passengers travelling, increase
buses.

15. Display Load Factor DataDisplay Load Factor Data
These data should be monitored and
displayed regularly, maybe through mobile
app, or electronic display boards.
The display of load factor data should beThe display of load factor data should be
regularly done, not only for buses but also
for Delhi Metro.

16. Limiting Load FactorLimiting Load Factor
Such exercise will develop a confidence in
public that if they want to use bus service
or Metro, they will NOT have to face
heavy crowd.heavy crowd.
If you see overloaded buses everyday, will
you be reluctant to travel by bus or not?
Is it not one of the reasons for people
buying more and more private vehicles?

17. NonNon--Route TravelRoute Travel
It is easy to get a bus from one stop to
another, but what if you have to go a couple
of kilometers off route?
Will you get a service or not?
This needs to be considered a need of time
to develop government owned auto type
This needs to be considered a need of time
to develop government owned auto type
system to ply passengers in case auto is not
available.
Presently OLA and similar parties providing
such services, but these need to be
enhanced particularly for smaller routes
having a span of 0.5-2.0 kilometers.

18. OverloadOverload
It is generally said that overloaded
vehicles create more pollution. However,
checking and weighing each and every
vehicle on the road is an extremelyvehicle on the road is an extremely
difficult task.
Overload vehicles not only create
instantaneous pollution, but also result in
damage to roads, due to which future
pollution rises due to obvious reasons.

19. Checking OverloadChecking Overload
Each and every weigh bridge must be
instructed to submit a copy of daily
weight measured of all the vehicles to
authorities. On the basis of collectedauthorities. On the basis of collected
information, authorities may issue notices/
challans to defaulter truck owners.

Later on, weigh bridges may be equipped
with online data submission to authorities,
so that an early action may be taken
against defaulters.against defaulters.
