  • Summary

    As an industrial revolution booms in Chile, the country’s air has been flooded by toxic emissions. Cities face the worst of the pollution, as factories are booming and urban centres are growing. Cars are one of the main contributors towards the accumulation of PM2.5. Sharing trips may help reduce the number of private and public vehicles on the road and thus reduce greenhouse gas emissions, travel time, and cost to individuals. In this study, I apply the concept of shareability networks to a survey of 113 591 trips taken in the city of Santiago in Chile, showing that with increasing but still relatively low passenger discomfort, cumulative trip length can be cut by 50 percent or more. I quantify the benefit of ride sharing in terms of traffic and emission reduction. I finally show that the ride-sharing potential is substantial, with nearly 100 percent of the trips shareable with current public transportation trip demand.
