MEXICO CITY , Mexico ( CNN ) -- Buses that carry women only are experiencing a smooth ride with passengers in Mexico 's capital . A woman rides on a bus exclusively for female passengers last month in Mexico City . Fans of the new service call their daily commutes more pleasant now that bus rides steer clear of too-close-for-comfort contact with men . `` We 're not just talking about sexual harassment , about rapes or about incidents of violence , '' said Ariadna Montiel , director of the Network of Passengers ' Transportation for the Government of the Federal District . `` But also about touching , staring , which is what generally occurs on public transport . '' The single-sex service , which started in January , is available on four major lines in the city , and it 's expected to expand to another 15 . Other plans include replacing male drivers with women . One woman described the service as `` excellent , '' saying it 's `` more comfortable too because it does n't make as many stops . '' Another passenger said she feels more comfortable and safer . Last year , the government received seven complaints of sexual abuse aboard the city 's buses , which provide 200 million rides each year , officials said . Authorities said that a single complaint is enough to justify taking such measures . Juan Flores , who has driven buses in Mexico City for 15 years and now steers one for women only , said he even notices a difference . `` I feel more tranquil , I work more peacefully and the interior of the bus is cleaner , '' he said .
