In general, transport systems and schedules worldwide have not been designed to meet the needs of women. In both developed and developing countries, women tend to make shorter and more frequent trips during the day than men, and are more often accompanied by children or elderly relatives. Women also have greater need of transporting water and wood for fuel, and of bringing food and other products to and from the market. Overall, their greater travel time means that they have less time to attend school or to participate in other economic activities. In addition, many public transport options are not safe or culturally appropriate for women and girls, including routes that are poorly lit or not well monitored and buses or trains that are dominated by male passengers. Improving the mobility of women and girls requires taking their specific needs and concerns into account when designing transportation policies.
