MIT Senseable City Lab
Potential taxi-sharing benefits in NYC
New interactive maps from MIT analyze the potential environmental and economic savings of ride-sharing in dense urban areas — in particular, the benefits of sharing taxicabs in New York City. The project, called HubCab, uses data from 170 million trips made by New York City's 13,500 taxis in 2011. High-resolution GPS coordinates and timestamps for each trip allowed researchers to pinpoint locations in the city that are high-traffic hubs for taxi pick-ups and drop-offs, as well as calculate fare savings, decreases in total miles traveled, and cuts in CO2 emissions if ride-sharing existed. The researchers found that taxi-sharing could reduce the number of trips by 40 percent with only minimal inconvenience to the passengers. The findings highlight the potential benefits of ride-sharing in New York and other cities, including lower vehicle emissions, reduced congestion, and savings in time and money. City planners could use commuter travel patterns identified by HubCab to develop more efficient ride-sharing systems and cut their overall traffic congestion, researchers say.
