Multilevel parking with automated very good one, this can be coupled with solar energy

Car pooling concept is best way to minimise the road congestion. Also govt can build super market in PPP model and can incentivise and subsidise the traders for shifting there shops from densely congested place. It will help to expand the footpath as well as fly over can be built and we can use the ground portion as parking place. Also we can built underground parking.
Govt should impose penalty as well as imprisionment for human encroachment of foot path areas.

The reality is that the city does not have space for cars. Use of public transportation should be encouraged, ply more buses, if needed A/C buses, so that people stop using cars in Mumbai. However,the best way to solve Mumbai's problem is to ease Mumbai from congestion. There should be very strong incentive to move businesses to Navi Mumbai/Thane area. Build excellent infrastructure and other facilities in Navi Mumbai/Thane area which will encourage businesses and people to move to these areas.

Parking problem and even traffic problem will resolve with below IDEA :
e.g. Just move some big IT companies from proper Mumbai to 50 km away.
this way if any disaster will come then some of the companies will not get affected.
Train/Road traffic will get diverted.
all problem will get resolve automatically.

Parking problem is a resultant of two other problems. a) absence of reliable / affordable / clean / comfortable public transport. b) no parking space. Need to have multi-level parking - atleast, 100/1000 families / houses. No new RWA should be approved by local bodies if it's without MLPs.

On Street Parking - Off Street Parking ! Is there place left on street for parking? Where people will walk? Have you consider how hawkers will use road there after? Even MCGM is well aware about this facts. Instead Govt should focus to make parking towers in prime areas. Why can't we make 30-50 floor parking towers. Just imagine how much cars can be accommodated in such buildings even we can half of the suggested. Prime Areas like Nariman Point, Dadar, Bandra, Andheri, Juhu etc.

And we can make an app on mobile where we can pay the charges on BMC app directly with mobile banking there with major service provider this can be done easily this will also solve problem of fake pay and park.

Sir in Mumbai BMC has made foot path on every roads which is a good innitative but where roads are small or only 2 lanes making footpath on both sides is not advisable. Also people should walk on them and hawkers should not be allowed to set up shops there. Due to this people don't walk on footpath made for them and there is no space for cars. Many places near church gate station pay and park charges is 80-100 rs pe hour there should be a unified charges

On parkings we should have footpaths compulsory on all roads and people particularly should be made to walk on footpaths to avoid any accidents. Stopping of cars on narrow roads should be completely stopped. Double parkings on road should be completely avoided as they disturb vehicular traffic. Sufficient parking slots should be built so that when people come out in their vehicles they can park in the slots and finish their work and move away.

Give permissions without formalities to buildings where builders have not built sufficient car parkings if they have sufficient space underground or otherwise. Handing over of convenience within 3 months of the OC should be made compulsory or the builder should be straightaway put in jail. The problems being faced for parking are due to the fact that builders are thinking that nobody can tough them for the wrongs they do.
