KIGALI, Oct. 17 (Xinhua) -- Africa's urban planners need to work closely with engineers to develop pedestrian-friendly infrastructure that promotes walking as a mode of transportation in African cities, experts and officials said on Tuesday.
"Walkability is the key to an urban area's efficient ground transportation. Walking remains the cheapest form of transportation for all people. Thus, the construction of a walkable city provides the most affordable and equitable transportation system," Pudence Rubingisa, mayor of Kigali, said while officially opening the 23rd International Walk21 Conference on Walking and Liveable Communities, which runs through Friday, in the Rwandan capital of Kigali.
