MIT study finds Uber & Lyft increase congestion, decrease transit ridership and don’t affect vehicle ownership

Green Car Congress

Researchers at MIT report that the entrance of transportation network companies (TNCs)—specifically Uber and Lyft, which together have a 98% share of the market—in cities led to increased road congestion in terms of both intensity (by 0.9%) and duration (by 4.5%); an 8.9% —Diao et al.

MIT Professor’s IoT Sensors Make Roads Safer

Cars That Think

Back in 2005, before smartphones were generally available, MIT Professor Hari Balakrishnan was so fed up with commuting delays in Boston that he built a mobile system to monitor road conditions. He interviewed for a faculty position at MIT and knew immediately it was where he wanted to work, he says. In the final year of his Ph.D.,

MIT/UC Davis professors challenge claims that ethanol production decreased gasoline prices in 2010 and 2011

Green Car Congress

Knittel/Smith results for implied gasoline price effects from elimination of ethanol for 2010 using Du/Hayes model and pooled-sample estimates. Christopher Knittel at MIT and Assoc. Our resulting estimates suggest that increases in ethanol production “cause” reductions in natural gas prices but increases in unemployment.

MIT study finds materials risk exposure increases significantly with vehicle electrification

Green Car Congress

The researchers devised a metric of vulnerability, referred to as exposure, which captures economic importance and susceptibility to price changes. The team analyzed part-level data of material use for seven current year models, ranging from internal combustion engine vehicles (ICEV) to plug-in hybrid vehicles (PHEVs), all provided by Ford.

MIT, Stanford and Toyota Research Institute use AI to predict accurately the useful life of batteries

Green Car Congress

Scientists at the Massachusetts Institute of Technology (MIT), Stanford University and the Toyota Research Institute (TRI) have discovered that combining comprehensive experimental data and artificial intelligence provide the key for accurately predicting the useful life of lithium-ion batteries before their capacities started to wane.
