tldw Hamburg wanted to build an urban highway network, but it wasn't complete and they built some nice things in the space left over.

Published in Transportation Research Record: Journal of the Transportation Research Board, the study analyzed data collected among riders in three metropolitan regions — the San Francisco Bay Area, San Diego, and Los Angeles and Orange counties — between Nov. 2018 and Nov. 2019. The data set consisted of 7,333 ride-hailing trips by 2,458 respondents.

About 47% of the trips replaced a public transit, carpool, walking or cycling trip. An additional 5.8% of trips represented “induced travel,” meaning the person would not have made the trip were an Uber or Lyft unavailable. This suggests ride-hailing often tends to replace most sustainable transportation modes and leads to additional vehicle miles traveled.

We predicted the amount, share, and value of land dedicated to roadways within and across 316 U.S. primary metropolitan statistical areas. Despite the amount and value of land dedicated to roadways, our study provides the first such estimate across a broad range of metropolitan areas. Our basic approach was to estimate roadway widths using a 10% sample of widths provided by the Highway Performance Monitoring System and apply our estimates to the rest of the roadway system. Multiplying estimated widths by segment length and netting out double counting at intersections provided estimates of land area. We also matched roadway segments and areas to existing land value estimates and satellite-based measures of urbanized land. We found that a little less than a quarter of urbanized land—roughly the size of West Virginia—was dedicated to roadway. This land was worth around $4.1 trillion in 2016 and had an annualized value that was higher than the total variable costs of the trucking sector and the total annual federal, state, and local expenditures on roadways. Conducting a back-of-the-envelope cost–benefit analysis, we found that the country likely has too much land dedicated to urban roads.

Banksy’s hope, it is understood, is that the uplifting works cheer ­people with a moment of unexpected ­amusement, as well as to ­gently underline the human capacity for ­creative play, rather than for destruction and negativity.

Some recent theorising about the deeper significance of each new image has been way too involved, Banksy’s support organisation, Pest Control Office, has indicated.

A contractor, who only wanted to give his name as Marc, told PA they were planning to pull the billboard down on Monday and had removed it early in case someone “rips it down and leaves it unsafe”.

He said: “We’ll store that bit [the artwork] in our yard to see if anyone collects it but if not it’ll go in a skip. I’ve been told to keep it careful in case he wants it.”

Mp3 Experiments feature thousands of people followed secret, synchronized instructions delivered via headphones. This 18th installment features some comments on urban planning.

For half a century, a litany of federal policies has favored large SUVs and trucks, pushing automakers and American buyers toward larger models. Instead of counteracting car bloat through regulation, policymakers have subtly encouraged it. That has been a boon for car companies, but a disaster for everyone else.
