David Matthew Levinson is an American civil engineer and transportation analyst, a professor at the University of Sydney since 2017. He formerly held the RP Braun/CTS Chair in Transportation at the University of Minnesota, from 2006 to 2016. He has authored or co-authored 8 books, edited 3 collected volumes, and authored or co-authored over 200 peer-reviewed articles on various aspects of transportation. His most widely cited works are on transportation accessibility and on the travel time budget. He has developed models of the co-evolution of transport and land use systems, demonstrating mutual causality empirically. He is a founder of the World Society for Transport and Land Use Research. In 1995 he was awarded the Charles Tiebout Prize in Regional Science by the Western Regional Science Association, and in 2004, the CUTC-ARTBA New Faculty Award. His travel behaviour research was featured in the book Traffic by Tom Vanderbilt. .. more

I’d think if they want higher across-the-board salaries (COLA) for their actual members they would renegotiate and give up fictional future union members. Obviously no reason for them to say that now.

But surely the contract expires multiple times before this line opens.

On Density and Synchrony (Scheduling Density)
Temporal coordination is about timing. Work and school schedules, transport services, parking, and energy use can be staggered or load balanced to avoid overload at any one moment. Tools include flexible work hours, congestion pricing, and off-peak utility tariffs. Some activities require synchrony, such as assembly lines or collaborative office work. Spatial coordination is about location. Co-location means more people in one place, i.e.

It's the kind of change a Democrat could never make. [terrible pun]. But now, more seriously, how will we pay tolls in Illinois?

Fun for all road tolling advocates!

(And yes, I suspect that from a wildlife perspective this is probably not ideal.)

How will robots get to work?
Our community has, for a long-time, been thinking about autonomous vehicles as the future of transport, and in some ways, they still are. But humanoid robots are also coming: see this article in USA Today, obviously there is still a lot of vapourware, but also some impressive technology. Humanoid robots have potential applications related to transport. They have the additional advantage of fitting into environments designed for people.

The federal government should be dissolved into almost nothing. Departments of Peace, Justice, Treasury, maybe nothing else. Everything else should be an independent institution/corporation/foundation with independent funding not subject to short term vagaries.
