"Post-Dec 16, security for women in the city has become better, but it is a long haul, (the change) is not going to be overnight. But the awareness on the security of women has increased," Dikshit told IANS.
Speaking on the sidelines of a conference here, the chief minister said Delhi Police was now more vigilant, and its personnel have been sensitised after the gangrape.
Four men have been convicted for the gangrape and murder of a 23-year-old physiotherapy intern, who died of the grave injuries she sustained in the attack.
Of the six involved in the crime, one was found dead in Delhi's Tihar Jail. A juvenile was held guilty too, and was sent Aug 31 to a reform home for three years.
The quantum of sentence of the four others convicted for the crime will be pronounced on Friday.
Rise in Delhi rape cases post-Dec 16: BJP
Meanwhile, the Bharatiya Janata Party (BJP) said on Thursday that there has been a 240 percent increase in the number of rape cases in Delhi since the gruesome Dec 16, 2012 gangrape and a 495 percent spurt in molestation cases.
Citing Delhi Police data, the state unit of the BJP said that from January to Aug 15, 2013, 1,036 rape cases have been reported from the city, as compared to 433 reported during the same period last year.
Similarly, 2,267 cases of molestation were reported in the first eight months of the year, as compared to 381 cases last year.
"It is ironical that in spite of the reprehensible rape incident last year, the cases of rape and molestation have increased in Delhi," BJP president Vijay Goel said.
Goel demanded that the Congress come out with an action taken report on the recommendations addressing the safety concerns of women put forward by the Justice Verma committee, set up after the brutal gang-rape.
"The Delhi government had promised to install CCTV cameras, GPS in all the city buses and also deploy home guards in these buses. But nothing much seems to have happened on the ground. The public transport in Delhi remains unsafe," Goel said.
