Many of the largest cities in the world are in developing countries. The rapid urbanization seen in many developing countries is also happening in Nairobi, Kenya which has resulted in heavy traffic congestion. A survey done in 2011 by IBM ranked Nairobi fourth in terms of “commuter pain”. Much of Nairobi’s road system was developed over fifty years ago for a city with only 350,000 inhabitants. Nairobi has swelled to almost ten times that size with 3.2 million inhabitants.
While almost 82% of the adult population in Kenya owns a cell phone, only 19% have a smartphone. This puts geospatial technology like Google Maps and Waze out of reach of most commuting Kenyans needing to find ways around the gridlock. To combat this problem, IBM’s Nairobi lab debuted a program last year called called Twende Twende which means “let’s go” in Swahili. The mobile app uses image recognition algorithms to convert data from Nairobi’s aging network of traffic cameras into real-time traffic information sent to drivers via SMS. For those streets not covered by traffic cameras, a separate algorithm predicts traffic patterns. This information lets drivers who text the name of a street know traffic conditions and suggests alternate routes to gridlocked areas.
