A Thomson Reuters Foundation survey of 1, female travelers in Tokyo, London, New York City, Cairo and Mexico City found less than half supported women-only sections on trains and buses to boost safety. But nearly 70 percent of women in Tokyo backed the single-sex carriages introduced in the city in to combat a phenomenon commonly known as chikan, or groping, on trains. More than half of women surveyed in the city said safety was their top transport concern, but seven in 10 were confident they could now travel without being subjected to sexual harassment or violence. Women in Cairo and Mexico City also said safety was their biggest concern about using public and private transport, and 60 percent and 55 percent respectively said women-only sections on trains and buses would improve safety. But less than 30 percent of women were in favor of women-only carriages in New York and London, where the time and cost of travel were seen as more pressing issues than safety. The poll, supported by Uber, comes as cities around the world increasingly bolster efforts to ensure women have safe, efficient transport to give them full and equal opportunities for jobs and education.
