Peak pollution controlled despite fog and adverse weather
- Load of particulates and nitrous oxides from cars reduced by about 40%
- Areas with higher car density recorded more improvement in air quality
- Decongestion of roads, leading to better utilisation of vehicles and reduced travel time
OTHER POSSIBLE TEMPORARY MEASURES
- Extending odd-even rule to two-wheelers
- Shutting power plants and industries
- Declaring school holidays
LASTING MEASURES THAT DELHI NEEDS
- Congestion charges on the basis of time and location of travel
- Tax benefits for CNG and electric vehicles
- Phase out old vehicles
- Timely completion of phase-III of Delhi Metro
- Remove entry taxes for cabs, autos and buses within NCR cities
- Rationalise taxes on buses
- Substantially hike car parking charges
- Expand bus fleet to 11,000 from around 6,000 at present
- Build dedicated lanes for cyclists and pedestrians
- Implement Bharat-VI emission norm by 2020
- Islanding of Delhi by diverting trucks and commercial vehicles
JOBS UNDER THREAT
- Personal drivers: Taking a car out on alternate days could mean fewer people hiring personal drivers
- Parking attendants: Fewer cars and dwindling parking revenue could mean a cut on parking attendants
