Hi Kavita,
In some locations, we use the "FOR SHE" service of radio taxis which are driven by ladies. Where this is not possible, we have a security guard accompanying ladies - no male is allowed in the ladies' car drop. The guard and the driver both need to undergo a police verification.
We also do the same in some cities where we use Meru taxis. Fixed taxis with drivers are available for us - here too, a guard accompanies the drop, and both the guard and driver have to produce a police clearance.
Hope this helps.
Brinda
