Uber / Lyft Implications: Vehicle Ownership, Transit, Electrification, Air Emissions, Traffic Externalities, and Equity - Shared screen with speaker view
Who can see your viewing activity?
(effects of shift away from transit)
Jermey…some of these externalities are more evenly distributed than others…G
Do you have any data on the effect of Uber/Lyft entry on VMT?
less greenhouse gas emissions (greater efficiency?) when hot, as well as conventional pollutants?
Last time I took a pooled ride to LAG from downtown NYC we drove all over Manhatten topic people up…Never again!
topic = to pick
On the previous slide, was it showing a greater crash externality with TNCs, is that from TNCs having a higher crash rate? If so, how do you break out driving behavior from TNC impact?
Is this complicated by the facts that there are some places where electric vehicles, or those with two or more folks in a vehicle, get to use faster lanes?
Of course, no reason we should consider internalizing the externalities *only* for TNC vehicles.
(Which btw, CA was trying to do)
My comment about equity above had more to do with the reduction of public transit offerings due to a reduction in ridership because people who can afford to use TNCs do so.
Super cool question from Jay. Actually, “should” they be lobbying for stuff like more stopsigns and other strategies that would also help them with vehicle automation pilots or charging station locations for EVs if they end up at the forefront of electrification.
Will the welfare impacts always be indeterminate, or are more regulations/taxes going to be surely harming wealthier individuals whose marginal disutility is socially acceptable (at least on the demand side)?
My favorite essay on the travel cost method: http://john-adams.co.uk/wp-content/uploads/2006/hyde%20park%20airport.pdf
Were the TNC adoption rates for each city compared with the amount of deadheading per ride?
Of course, there is also an income equity benefit for ride hailing (taxicabs are a well-known first job for immigrants), and - under certain circumstances - TNCs.
Oh, don’t start complaining about Portugal.
Doesn’t that get at the open question of what equity looks like? Do we necessarily want to see everyone having equal access to TNCs across a whole city?
I gotta head to office hours. Thanks!!
